Turbine on a VAZ 2114 - how to install a turbine on a VAZ 2114

Installation of a turbine on an 8 valve VAZ 2114 engine

Installing a turbine is the most common way to improve the power characteristics of VAZ cars. Atmospheric modification of the engine with a cylinder head bore, a sports exhaust system and sports shafts will be more affordable, but it is limited to a limit of 120-130 hp. Proper turbocharging allows you to remove more than 200 horses from a car.

When choosing between turbocharged and naturally aspirated engines, proceed from the tasks assigned to the car. Refinement of the naturally aspirated engine allows you not to get lost in city traffic among more powerful foreign cars. Turbo is better for racing.

In addition, it is almost impossible to legalize a turbo engine in a VAZ in Russia.

INSTALLING A TURBO ON A VAZ 2114: WHERE TO START

Installing a turbine on any car begins with a thorough examination of the hardware. You can’t just go to the store and buy a ready-made kit. And even if it is possible, the system will still have to be modified.

Turbocharged engine VAZ 2114

If you take on this task, consider the following:

1. A number of stock units of the VAZ 2114 are unsuitable for a car with a power of over 150 hp. It will not be possible to do without re-equipping the suspension and brakes, installing wider wheels with a turbo engine.
2. Tuning foreign cars is partly easier if the model being tuned has “bigger” brothers with turbo engines. Tuning usually comes down to searching, purchasing and adjusting ready-made factory units. It’s more difficult with Togliatti-made cars - VAZs don’t install turbines. Fortunately, in large cities there are tuning studios that develop and produce tuning parts. True, their products are mostly unlicensed, so there will be problems with legalizing changes.
3. The correct choice of turbine is the key to successful turbo tuning. Before realizing your dream, we recommend that you read brief descriptions of the turbines used to modify the VAZ.

TURBINES FOR VAZ CARS

There are many options for installing a turbine on the 2114 model. Theoretically, anything can be adapted, but the following models are best suited for an 8-valve engine:

• Garret 1752;
• Mitsubishi TD04 (installed on Mitsubishi Lancer EVO, Subaru Impreza WRX, and some other models);
• IHI VF10 (this model was equipped with the 1st generation Subaru Legacy cars), as a variant of the VF11-20 (stock for the 2nd generation Legacy);

The list can be expanded with dozens of positions, including more powerful turbines TD05, TD06, VF23-30.

Moreover, if there is not enough money for new equipment, it is not difficult to find used kits in decent condition due to the transition of their owners to more powerful equipment

TURBO KIT GARRET 1752

Turbo kit Garret 1752

Turbines from Garrett are consistently among the most popular among VAZ owners.

Among the reasons for this:

• sold as a ready-made set, there is no need to assemble individual elements using spare parts at car dismantling yards;
• relatively low cost (a new set will cost 30-35 thousand, used ones can be found in the range from 15 to 25 thousand);
• without any special modifications, you can remove the boost from the car to 0.5 bar, increasing power to 120-130 hp. and torque up to 180-200 Nm;
• with additional modifications to the boost system, the boost can be increased to 1 bar, power – up to 170-200 hp, and torque – up to 240 Nm.

The boost kit from Garret is optimal for novice fans of turbo tuning. By setting the boost to 0.5 bar, you can get a good increase in power without reducing engine life. For serious “rides,” this option is not suitable due to its limitations.

TURBINES BASED ON TD04 TURBO-COMPRESSOR

Turbine TD04L with actuator

The Mitsubishi TD04 compressor and its various invariants (TD04H, TD04L, TD04HL and others) are one of the most common Japanese turbo systems in Russia. Installed on Mitsubishi Lancer Evolution IV-V generations, turbodiesel Mitsubishi Pajero, as well as many Subaru models of the mid-1990s.

The advantage of this compressor is that in the factory version it made it possible to extract a solid 280 - 340 Nm and 280 hp from 1.6 - 2.0 liter engines. In addition, it is compactly placed under the VAZ hood.

High-performance turbos like the Garret GTX30 (installed on the Toyota Chaser or Mark II and German BMW e39 cars) are more difficult to place under the hood. There are precedents, but doing it on your own is not easy.

The build quality of the Japanese turbine is higher than the Chinese Garrett, and the resource reserve allows you to purchase even well-worn equipment. A distinctive feature of the turbine is its flat torque level. Peak performance varies depending on the type of compressor and additional equipment.

For racing where acceleration is of paramount importance, it is better to consider other turbos. On tracks with long straights, where it is possible to fully use the maximum revs of 4 - 4.5 thousand, the TD04 can compete with more productive models.

TURBINES BASED ON IHI VF10 COMPRESSOR

Turbocharger VF22

Subaru has experimented with turbo engine configurations more than other manufacturers. On the same WRXs you can find Garretts, and the famous Apexi, and Mitsubishi. Not the last place in this series is occupied by the American manufacturer IHI, whose superchargers were installed on legendary cars like the Chevrolet Camaro.

VAZ is equipped with many variants of turbines from IHI, including:

• VF22
• VF23
• VF24

These are classic drag racing turbos that boost extremely quickly, already at 2800-2900 rpm.

The VF10 is less powerful than either of these options. Peak power is about 250 horses (rarely, with very professional tuning and a strong reduction in resource - up to 300). By comparison, the 20th and 30th numbers are capable of developing up to 325 or more horses. But for the VAZ engine, the “ten” (as well as the VF11-20 turbines similar to it), according to many turbo experts, is optimal.

When compared with the TD04 and even the TD05, the VF10 will be faster at the bottom, but the turbo lag will be more noticeable. A VAZ 2114 with such a turbine will feel better on drag or in circuit racing with a minimum of long straights.

TURBINE INSTALLATION: PURCHASE OF PARTS

Assembling a turbo car is a creative process; much (if not all) depends on the construction kit you assemble.

It is impossible to give unambiguous advice here - all answers are only specific.

In the VAZ store you will need to purchase:

• new pistons (usually Niv ones are used);
• rings (the higher quality the better);
• cylinder head gasket (iron, suitable from Kalina for 8 valves);
• fuel regulator at 2.5-3 bar;
• throttle;
• vacuum tubes, tees, bends, etc.

Simple turbo kit for VAZ 2114

If you buy a ready-made turbo kit, everything is simple. We order and receive. If not, online stores, Japanese car dismantling yards and other e-bay are available. You will need:

• turbocharger (from the above or whichever you like);
• gaskets (pipe, downpipe, oil drain);
• inlet receiver;
• exhaust manifold (there are ready-made solutions for Garrett and TD04; for other turbines you will have to assemble it yourself);
• a set of pipes, clamps and other small things (ready ones available);
• intercooler (you can start without it, it gives an additional increase of up to 10 hp);
• fuel pump (with a capacity of about 250 l/h, the better the quality, the better);
• injectors (budget option - from Volga, more productive - from Subaru or Mitsu Evo);
• blow-off (bypass valve for excess air pressure in the turbine, deserves a separate discussion);
• boost controller (for the VAZ 2114 it is better to use a mechanical one, it is simpler and cheaper, however, you can install an electronic one);
• absolute pressure sensor (ABP), air temperature sensor (ATS), turbine pressure sensor (TP).

The budget can start from 40-45 thousand rubles and tend to infinity, depending on the cost of components and the amount of work performed in the tuning studio.

INSTALLATION: PROCEDURE

Turbocharging an engine is a lengthy process. Plans to “turban for vacation” are practically impossible. Plan your time in advance. If the car is your main one, it makes sense to think in advance about purchasing a temporary means of transportation.

Most turbocharging features are unique to different models of compressors and other equipment. The description below is average and schematic.

Stage 1. Preparing the motor . The engine is disassembled, a complete inspection of the cylinders, crankshaft, connecting rods, liners and oil pump is carried out, and the block is polished. Pistons are purchased after preparing the cylinders (boring may be required).

The cylinder head is checked (if necessary, the cylinder head is ground), hydraulic compensators and valves can be used as standard.

Stage 2. Assembly of attachments. New injectors are installed and the fuel pump is replaced. VAZ 2114 engines with 8 valves have a number of advantages compared to 16-valve engines. Firstly, there is no need to be clever with the return. Secondly, it is much easier to connect the fuel pressure regulator.

Next, installation of the receiver, installation of the exhaust manifold, fitting of the turbine. If you purchased an intercooler, we find a place for it and install it. We install piping and blow-offs. We are preparing the oil and cooling supply to the turbine. We remove the air flow sensor and install the DBP and DTV system.

Stage 3. When everything is assembled and secured, there is confidence that nothing is leaking anywhere, the most difficult part begins - setting up. All horsepower, Newton meters and fuel consumption depend on the skill of the tuner. There are good turbo specialists in large cities - do not spare money on their services, otherwise a much larger sum will go down the drain.

A good boost is the result of intellectual work and skill. For the results to justify themselves, remember: there can never be too much information. Study the question thoroughly - the result will amaze you.

Items required for installation

To install a turbine on a naturally aspirated engine, you will need to prepare the following parts:

1. The turbine itself.
2. Electronics that will provide fuel supply control.
3. An exhaust manifold.
4. High performance injectors.
5. Intercooler for air cooling.
6. The pipe connecting the turbine to the muffler (downpipe).
7. Air supply line made of stainless steel and aluminum tubes.
8. Pipes supplying oil and coolant.
9. Silicone pipes designed for connecting tubes.

To prevent overheating of the turbine, an additional cooling system is installed. An oxygen sensor is built into the downpipe. The turbine impeller rotates at very high speeds. To eliminate the risk of its premature failure, oil is supplied to it, which will be supplied from the engine. Excess pressure will be released using a valve called a blow-off.

Why is a turbo engine needed?

When installing a turbocharger on a car engine, compressed air enters the engine cylinders. It occupies the same volume as before installing the turbine, but due to compression, its specific mass increases. It becomes possible to proportionally increase engine power.

Fuel consumption does not increase when installing a turbine. This is achieved by increasing the density of the air as it cools in the engine cylinder. Emissions of combustion products are also reduced.

The most commonly used compressor is exhaust gas powered. It is driven by the flow of exhaust gases to the compressor drive. As a result, fuel and engine energy are not wasted additionally, as with a mechanical compressor drive.

A little theory

Toyota Sera 1.5 turbo 4WD Serafima Logbook MythBusters FHE connecting rods

Such improvements can be carried out more effectively by those who have a clear understanding of their own actions. To do this you need to understand the theoretical part.

So, the car’s power and fuel consumption depend on the properties and degree of enrichment of the fuel-air mixture entering the cylinders, as well as on its volume.

The fact is that an ordinary engine, when operating, pumps air into itself due to the vacuum created by the piston. In a turbocharged power unit, this work is done by a turbocharger. At the same time, the air is compressed earlier, which allows you to pump in a larger volume. In other words, you can burn a larger volume of fuel. The result is an increase in engine power in relation to engine volume and fuel consumed.

One fundamental point: air, as is clear, heats up under strong compression. Secondly, it will heat up during compression in the combustion chamber. With all this, detonation may occur. And, in addition, due to heating, the air density in the cylinder will decrease, which will naturally reduce the efficiency of the entire system. To remove these bad phenomena, intercoolers are used - air coolers from the turbine. They are a radiator.

As already mentioned, there are two types of compressors:

• A turbocharger that operates by using the energy of exhaust gases. The processed gases enter the impeller and spin it, which is why air is pumped;
• Mechanically driven compressor. It is powered by a motor drive. With all this, efficiency decreases and fuel consumption increases compared to the first version of the compressor, because the mechanical supercharger takes away part of the power from the internal combustion engine.

The entire system, not counting the turbine itself, contains several more fundamental components that need to be kept in mind during installation:

• a control valve that maintains this pressure;
• a bypass valve, which ensures that compressed air returns back to the compressor inlet pipes if the engine throttle valve is closed;
• a bleed valve that releases compressed air into the atmosphere when the throttle valve is closed;
• air pipes;
• oil pipes (serve for lubrication and cooling of the turbine).

Hi all ! In this video I will talk about the design of a turbo engine in our implementation. Enjoy watching.

Advantages and disadvantages of the turbine

As a result of using a correctly selected turbine, engine characteristics, including those on the VAZ 2114, are improved:

1. Fuel consumption is reduced compared to other ways to increase engine power.
2. The ratio between the weight of the engine and its power is optimized.
3. A turbocharged engine is quieter than an engine with the same power without a turbocharger.

The disadvantages of using turbines include:

1. The need to change oil and filters more often. In this case, only special oils can be used.
2. Short service life of the turbocharger, the need to replace it.
3. The effect of an “air hole” or “turbo lag” when starting the engine is due to low crankshaft speeds and a small amount of exhaust gases, which are not enough to start the turbine.

Mechanical supercharger for VAZ - pros and cons

The larger the engine and the more cylinders it has, the higher its power. This is the very first conclusion when observing motors and machines. But this is not always the case. The more fuel burned in the engine cylinders, the more power it can produce. But the cylinder volume is finite, and I want to have increased power. This is where a mechanical air blower comes to the rescue.

The principle of its operation is extremely simple and works on any car, including the VAZ 2107, 2106, 2114, 2112 family - it provides additional air to the engine, resulting in:

• the purging of the cylinders increases, and they are better freed from the remains of burnt fuel;
• more fuel enters the engine cylinders, which ensures more power;
• The compression ratio increases, which also gives an increase in power.

This approach is almost similar to the turbo mode used on diesel engines. Only there, for these purposes, a turbocharger is used, driven by exhaust gases, and in this case, a mechanical air blower, which is connected to the engine crankshaft by a belt. This approach is much simpler, the air supply depends on the engine speed, the higher it is, the more air is supplied; and also does not require ensuring the operating modes of the turbine and can be done with your own hands on any VAZ car.

Do not forget that you are boosting a VAZ engine, be it any of its models 2107, 2106, 2114, 2112, the work must be carried out comprehensively, and only then is it possible to obtain the expected result. However, this is not such a big price to pay for the increase in power.

Turbine for VAZ 2114

The choice of turbine for a VAZ 2114 8 valve has its own characteristics. First of all, this is due to the fact that the AvtoVAZ plant does not produce turbo engines.

Therefore, it is necessary to select turbines from foreign manufacturers that are suitable for an 8-valve engine:

1. Garret 1752 turbines (made in China) - most often used when installing a turbo on a VAZ 2114 8 valves. Their advantages:
   sold as a ready-made set - there is no need to assemble all the components separately;
2. reasonable price compared to other manufacturers;
3. do not require complex modifications to the engine to achieve power of 120-130 hp;
4. upon modification, a power of 170-200 hp is achieved, and torque increases to 240 Nm.
5. Mitsubishi TD04 and different variants of this compressor:
   has compact dimensions;
6. large resource of work;
7. high build quality;
8. without modifications it is capable of accelerating the engine to 280 hp. power and torque 280 – 340 Nm.
9. IHI VF is a turbocharger made in the USA (previously it was equipped with Subaru Legacy I). For VAZ you can use IHI VF10, VF 20-24. Their advantage is high peak engine power (from 250 to 325 hp depending on the turbine model). The disadvantages include noticeable turbo lag when starting the engine.

Important ! The factory suspension and braking system of the VAZ 2114 are unsuitable for using a high-power engine (more than 150 hp). Therefore, when installing a turbo system, it is necessary to further tune them. It is also recommended to increase the width of the wheels.

How to install a turbine on a VAZ 2114

Installing a turbine on a VAZ 2114 requires preliminary preparation.

You need to purchase spare parts for VAZ in the store:

• new pistons and rings (possibly from Niva);
• cylinder head gasket;
• fuel pressure control;
• throttle valve;
• vacuum tube system.

If the turbo system is not supplied as a kit, but only a turbocharger is available, you need to buy:

• intake receiver and exhaust manifold;
• fuel pump - preferably with a capacity of 130 liters per hour. Submersible gasoline pumps from various manufacturers are suitable for injection-type engines. When selecting, you need to focus on the desired engine power;
• fuel injectors with the ability to supply a larger volume of fuel - possible from Volga or Subaru;
• overpressure relief valve;
• boost controller – a controller for regulating turbocharger pressure. It can be mechanical or in the form of an electromagnetic valve;
• pipes, clamps, gaskets, etc.

Be sure to purchase new sensors - absolute pressure and pressure in the turbine, and air temperature in the intake manifold.

Next, it is necessary to inspect the engine - disassemble and fully inspect its key mechanisms (cylinders, valves, crankshaft, oil pump, etc.). If necessary, replace with new ones. Spark plugs and ignition system wires may also need to be replaced.

Sequentially install all components of the turbo system. To adjust the operation of the turbo engine, it is advisable to seek the services of a specialist.

Thus, installing a turbocharger on a VAZ 2114 can significantly increase engine power and improve vehicle performance. The main thing is to choose the right turbocharger and components, and take a responsible approach to installation and configuration issues.

How to install an air blower yourself

There are several approaches that allow you to install a mechanical air blower on VAZ family cars with your own hands. This means making a device yourself that provides turbo mode or boosting the engine, or using a ready-made KIT kit.

Homemade supercharger for VAZ

With this approach, the mechanical air blower will be decisive. The entire future design depends on it. The main thing is to find an air supercharger from an imported car that meets the requirements, or you will have to use a homemade one. This is also possible, and in this case suitable parts and components from completely unexpected devices, for example, a vacuum cleaner, are used.

When making such a homemade air supercharger, you need to take literally everything into account - dimensions, weight, placement in the engine compartment, how and where the drive pulley and belt will be located, the performance of this device, operating modes (short-term or long-term), the possibility of lubrication and much, much more. Once the compressor becomes clear, it is necessary to calculate the implementation of the turbo mode for the engine.

Even the far from complete list of questions shown shows that making a homemade air supercharger for a VAZ of any family, be it 2107, 2106, 2114, 2112, is quite difficult, but possible. An example would be a photo showing that such work has been successfully completed. True, this is not a VAZ, but the fact itself is important - it is possible to make a homemade air compressor in which its drive unit is connected to the engine crankshaft.

Do-it-yourself drive supercharger - from a KIT kit

Yes, there are such kits on sale that allow you to implement the turbo mode in VAZ 2107, 2106, 2114, 2112 cars with your own hands. As a rule, it includes everything needed to assemble and install such a device on a car - the compressor itself, belts, drive unit , brackets and air ducts. What such a kit is like can be seen in the photo below.

As an advantage of implementing the turbo mode in this way, it is worth noting that it is tailored specifically to VAZ cars of one model or another (2107, 2106, 2114, 2112). The advantages of this approach also include the fact that under some conditions, when the level of additional pressure created is not more than half a bar, no intervention is required in the vehicle’s fuel system.

Turbocharging for a VAZ, who cares

Turbocharging on a VAZ is certainly exotic. But the power advantages of turbo engines over “aspirated” ones themselves encourage the emergence of more and more cars that received a turbine. And not all of these cars are foreign cars...

Theory

Let's start with the theory. There is simply supercharging (mechanical supercharging, charger) and there is turbocharging. In both cases, the boost is created by a turbine installed between the air filter and the intake manifold. The difference is what exactly drives it.

In the first case, the engine itself turns the turbine. One of the advantages is the direct dependence of the turbine speed (the pressure created by the turbine) on the speed, i.e. no delayed reaction (turbo lag). The downside is that the engine spends part of its power spinning up the turbine.

Turbocharging is more complicated because consists of 2 turbines. One pumps more air into the engine and is driven by another turbine, which is installed immediately behind the spider (exhaust manifold). Thus, the chain looks like this: exhaust gases rotate one turbine, which is connected to a second turbine that forces air into the engine. The advantage of turbocharging is that it has greater efficiency because does not require engine power to rotate it. Minus turbo in the presence of the “turbo lag” effect. What does it look like? You sharply press the gas to the floor and wait for an instant response from the engine. And in order for a turbo engine to produce maximum power, it is necessary to sufficiently spin up the turbine, which “comes to life” only when the engine reaches 3000-3500 rpm.

Turbines can be conditionally divided into 2 groups: low pressure (up to approximately 0.2-0.6 bar) and high pressure (up to 1 bar and above). If a high-pressure turbine requires a fairly serious modification of the engine, then for a low-pressure turbine you can leave almost everything factory, but more on that later.

In fact, the main goal is to get the maximum possible number of horses. Well, at least for those who like to drive so precisely J With the same displacement, a turbocharged engine can have almost 2 times more power with approximately the same fuel consumption. So, small-displacement turbo engines have recently come into fashion. Fiat has been building small city hatchbacks with turbo engines and the dynamics of a sedan with a 3-3.5 liter engine for quite some time. A simple example of this is the Fiat Grande Punto with a 1.4 turbo engine with a power of 120 to 150 horses, and in some modifications up to 180. However, similar engines appeared in VW.

How can you boost a turbocharged engine?

The specificity of these engines is such that if some improvements give practically nothing on naturally aspirated engines, then on turbo the results obtained are simply amazing. A simple example is forward flow. Many people have the opinion that with it the engine “breathes” and spins easier, our forum is proof of this. But these are only subjective opinions. If in the case of a naturally aspirated engine the power is given more by the sound than the forward flow itself, then with a turbo, with the correct intake and exhaust you can achieve very good results.

The picture is the same with such a popular modification as chip tuning. If this procedure gives an aspirated engine no more than 10% of power, then a turbo will easily give up to 25%

Installation of turbocharging on a VAZ

Let's consider a more budget-friendly option, in terms of modifications, with a low-pressure turbine and a VAZ 21083 engine with distributed injection.

The cylinder block, crankshaft and connecting rods can be used as standard. Camshaft and valves too. The difference may be in the pistons and cylinder heads because... installing a turbine requires reducing the compression ratio. And this can be achieved either by enlarging the combustion chamber, or by using special pistons. Although you can leave the original pistons and limit yourself to just the head.

The exhaust is also different - there is now a turbine between the exhaust manifold and the exhaust pipe. The resonator and muffler can be used as standard ones, although a direct-flow exhaust can be installed to obtain more power.

The injection needs a larger receiver and a non-standard control program. The lubrication system will also require minor changes.

Low pressure turbine - at your discretion and capabilities. In the case of a VAZ, the turbocharger is mounted above the right wheel drive between the exhaust manifold and the exhaust pipe. The compressor is supplied with 2 air pipes. The first is connected to the air filter, and the second to the receiver.

Thus, the most expensive and scarce part is the turbine itself.

Remember also that in addition to the engine, you will also need to modify the brake system and, quite possibly, the transmission.

Installing boost on the engine

Installation of the turbine should be carried out only by those motorists who have sufficient experience and knowledge in the technical features of the operation of the entire system. Direct installation instructions are as follows:

After purchasing a supercharger, you need to unpack it and conduct a visual inspection - the body must be intact and have no deformed areas. It is also necessary to check the technical condition of the oil supply hole. Check carefully - there should not be even the smallest parts inside the boost. Before directly installing the turbine, it is necessary to fill it with oil. The type and characteristics of the oil play an important role in determining the performance of the device and the reliability of the entire system. The turbine should be positioned so that the oil supply hole is at the top. Oil is poured into the hole, which should fill the turbine to the brim. Using a hand pump, you need to create pressure that pushes the oil into the interior and lubricates all the internal parts. During pumping, a hissing sound may be heard - this is normal. The procedure is performed several times, after which all the oil is poured through the drain hole. The oil supply hole is located strictly vertically and is connected to the installed compressor on the engine

It is necessary to pay attention to the inclination of the feed hole angle. The permissible deviation from the norm should be within 10-15 degrees

The car owner must make sure that the oil drains freely, without additional force. For ease of installation of the turbine, it is recommended to remove the heat shield, generator and exhaust manifold. After this, all antifreeze is drained. A hole is carefully drilled into the engine, into which a fitting with a thin layer of sealant is then installed. A heat shield, the turbine itself and the intake manifold are installed. The next step is to attach the treatment hose to the fitting and turbine, and then install the external wastegate. A silicone hose is attached to the fitting, which is cut in half and connected to the T-fitting. After this, all that remains is to install the intake piping and intercooler.

And a visual video with the installation of a turbine on a VAZ 2109 engine:

After installing the turbocharger, it is necessary to conduct an initial test of the functionality of the entire system. To do this, you need to start the engine from the starter. In order for the starter to be able to crank the engine, but not start it, the car owner must remove the voltage wires. In this case, the oil pressure sensor will go out, and the pressure on the oil supply line will drop significantly. If the entire system is working normally, you need to start the engine and leave it running for 10-15 minutes at idle speed.

The first thousand to one and a half kilometers must be carried out in run-in mode. In this case, the running-in mode should be such that the turbocharging does not develop a pressure of no more than 0.5 bar. Drivers who do not have a cabin pressure sensor installed in their vehicle should not exceed 50% of the rev limit. Also, car enthusiasts should remember that the turbo must cool before stopping the engine completely.

The diagram below allows you to see what place it occupies in the system.

Turbo VAZ - instructions for turbocharging

Instructions for installing a turbo on a VAZ

Through the efforts of specialists, we decided to write instructions for beginners on how to independently install a turbine on a VAZ car for dragging.

The very first and most important question is where to start?

First of all, when you buy a car (especially if it’s used), I advise you to pay attention to its condition. If you understand this or want to become better acquainted with the machine and its structure, I advise you to disassemble it to the ground. Only when we strip everything down to the body will we be able to see the scale of the problem.

The most important problem we may encounter is rust. Most often, the bottom, fenders, and sills rust heavily. The “TV” is also a problem area for the “chisels”.

You must understand that a car made by VAZ has very thin metal, and such metal is not intended for high loads (the metal will simply tear), and rusty metal will “die” even earlier than usual, which is very dangerous for us and those around us. Therefore, we take a welding machine, fresh iron and replace all the rotted metal with fresh metal, or we drive the car to a service station.

We replace almost all of the metal in the engine compartment with stronger iron. Have you fixed all the metal jambs? Is the body like factory? Well done! Let's continue.

Now you need to put the car in order and make it move at least in stock. We change the wiring, put the engine in order (or immediately change it to a “gear”), gearbox, brakes. This is our starting point in turbocharging.

If you have returned your car to its original condition, and you still have the desire to turbocharge it? Let's continue.

Which engines are easier to turbocharge?

The simplest thing is to take a VAZ 16-valve engine. It is easy to repair and tune, and what is most important for us is that it can provide us with power suitable for motorsport without huge costs, effort and modifications to the car. A 16-valve valve is initially more powerful than any VAZ engine.

Let's look at other VAZ engines.

— Old carburetor engines cannot be turbocharged. — An 8-valve injector could be suitable, but we are building a racing car and every horsepower is important to us. — The 16-valve engine is our choice for drag!

When considering the option of an engine from a foreign car, you must understand that it will cost us quite a large sum and will also require large modifications. The foreign engine is more complex in design than the VAZ engine, and without a specialist you are unlikely to understand it. Our choice is “shesnar”.

What is needed to build a turbo engine?

For people who want to get 200+ hp. It is advisable to obtain a “Kalinovsky” block, since it is higher (+2.3mm). A dozen or more will do, but we are building a car for racing and every horse is a victory, so it requires a “Kalinovsky” crankshaft with a crank diameter of 75.6 mm.

We select forged pistons and machine a recess for the desired compression ratio (it is better to contact a specialist or buy in specialized stores).

Turbocharger

The small one works at low and medium speeds, but stops at high speeds, therefore the large compressor does the opposite.

• TD05 – Mitsubishi. Boost at 3k rpm. 250-300 hp
• IHI VF10 is a much larger turbine than the Subarov one. 250+ hp
• IHI VF22 – drag turbine. The largest of the series.
• Turbines are also good, but they are expensive and you need to wait until your order arrives.
• There are also many Chinese turbines on our market. The quality is weak, but the price does not bite. T3, T4 – 300+ hp

Turbo engine cooling

Everything is simple here. We need a new copper double-row radiator (2110) as it is much more productive than any VAZ radiator.

Intercooler.

A very large intercooler can cause so-called “turbo lag” problems. Turbo lag is how long we have to wait for boost pressure after we open the throttle. And the small one will not have time to cool the air.

Blow-off valve

An important part of a turbo engine, its function is to release part of the compressed air after closing the throttle valve. Otherwise, excess pressure may break all rubber connections. There are a huge number of options on the market, from stylish ala Lamborghinis to almost homemade ones.

Westgate valve

It is needed to allow part of the compressed air to bypass the turbine to maintain a given pressure in the turbo system. There are also a large number of executions.

Fuel system for VAZ turbo engine.

The fuel system must have a return line and a fuel pressure regulator installed in the rail. It is permissible to use an external fuel pressure regulator, but it must be connected with a vacuum hose to the throttle receiver, because In order for the injectors to overcome excess pressure in the throttle space, the pressure in the ramp must also increase.

Fuel pump

. The stock one is not suitable, its performance is too low. We take either from Volga or Walbro - 255 l/h.

Injectors

. Stock again won’t work, we need 350cc or more. DEKA 630cc injectors are suitable for us, for 200 hp engines. BOSH will also fit.

Everything is installed without any problems. You can do everything yourself (except perhaps for the firmware and configuration). If you have no time/too lazy/don’t want to tinker, then you can give everything to the service. There are no complicated parts or connections in what we need to get, everything can be done by yourself. Spare parts for attaching to the engine are usually included with the part. And if you have to buy more, it won’t be too difficult.

Exhaust system for VAZ turbo engine.

The exhaust system releases exhaust gases from the engine. This is a very important part, we don’t want to change the engine ahead of time, do we?

The temperature of the gases leaving the engine is enormous, about 900 degrees, when leaving the cylinder. In the case of turbocharging, these exhaust gases must not only be removed, but directed to the turbine wheel for spin-up.

You've all probably heard of the "spider". "Spider 4-2-1" is a system in which gases enter four pipes, are then collected into two, and then into one. The system is effective at medium speeds, a good choice for driving on the streets and rare “bullets” from traffic lights. “Spider 4-1” is a system where gases from 4 pipes are immediately combined into one. Effective for high speeds. Our choice.

Suspension for turbo VAZ.

Suspension affects handling. Therefore, for a car that plans to overtake everyone and everywhere, it needs to be modified. I advise you to modify the suspension thinking about your own safety, because if at full speed something falls off due to old age, the car may become uncontrollable, which can lead to an accident. Let's consider suspension options.

1) Soft suspension

: Pros: smooths out potholes, rides smoothly and comfortably Cons: poor maneuverability, rolls when cornering, skidding.

2) Rigid suspension

: Pros: turns like a glove, maneuverability, instantly reacts to steering wheel turns. Cons: It will be rough on the bumps!

Clutch and transmission for turbo vaz

The choice of clutch must be approached thoroughly. The clutch must be selected taking into account the engine power and torque. The stock clutch is designed for a quiet ride! We have several options:

a) budget: basket with increased downforce (there are different options). This option firmly holds the driven disk and increases the force on the pedal (pump your legs otherwise, you will lose a split second at the start). b) not budget: ceramics. It can withstand the stress of motorsports. Our choice.

Gearbox for turbo VAZ

A stock box is a box designed for quiet movement, standing in traffic jams and stirring up dirt in the countryside. The stock box has a very short first speed, only up to 40 km/h. Short first means that we will have to waste time and torque when switching to second.

To solve this problem we must choose a range of gear ratios. The optimal choice for turbo engines 103 series. The main pair reduces the speed transmitted from the engine to the wheels by about 4 times. The higher the gear ratio, the better the acceleration and the lower the maximum speed. Our choice is 3.7 or 3.9

Tuning a VAZ turbo engine

All this is done using a “wastegate”; the less pressure is released into the atmosphere, the greater the pressure in the system.

There are several ways to adjust the pressure, the best of them is a boost controller. You need it to set the pressure you need right from the cabin. It works simply, it prevents the safety valve on the manifold from releasing pressure, which contributes to a temporary increase in pressure.

Firmware

The standard control unit program requires significant adjustments. A properly tuned turbo engine will be more powerful, run smoother and be less voracious in terms of oil and fuel. The most reliable option is to find a specialist in your city (or in a neighboring one) who is not doing this for the second time in his life. You don't want to overhaul the engine every two days, do you? Therefore, firmware is a crucial moment.

What other improvements are needed?

The stock engine is not designed for racing loads, so most of the components and spare parts are replaced with more efficient and durable ones. This applies to pistons, rings, pins and connecting rods...

Also a prerequisite is the modification of the cylinder head channels; we need to make the timing system more efficient. 40% of success depends on the “head”.

We must remember that we are building a 70 hp production car into a 200+ hp race car. Stock and life-killed components are not designed for this, so you must understand that when the project is ready, there will be nothing left in the car from the stock, you will have to go through the entire car down to the bolt.

How to refuel a turbo engine

?

You need 95 or 98 gasoline. 98 is preferable for those who like “gas to the floor.” 92 in no case, you will destroy the turbine ahead of schedule and without getting a decent result from the speed, since low-quality gasoline increases the combustion temperature, which negatively affects the turbine blades and the engine as a whole.

What oil to use

?

The 16-valve engine has hydraulic compensators and for their best performance you need to choose synthetics. Yes, it’s not a budget, but we demand the best results from a car, right? So for this we need to give her the best.
