How to increase the power of a car without rebuilding a NIVA 4x4 engine

Let's look at the example of NIVA 2141 Lada 4x4, how you can increase hp power with the help of additives and oil additives.

NIVA is designed for off-road use, and its engine is not the most powerful for acceleration, overtaking or driving uphill.

Here under the hood there is an 8-valve 83 hp. engine injector.

But it drags well when driving in mud, slush, deep snow and steep ruts. But they also drive it on the highway, and here the performance is not the most outstanding.

When pressing the gas pedal, I would like to get better acceleration.

And this can be done without boring the motor to increase power.

And with the help of an effective additive for a sharp increase in torque, rapid fuel combustion.

But to get a result plus 5 - 6 hp, you need to do everything comprehensively. Firstly, after purchasing a LADA, you need to drain all the fluids in all components that were filled from the factory. Change everything in the box, in the engine, in the axles, in the transfer case, especially the antifreeze.

Not the best oils are used to protect parts from friction and wear.

Installation of turbocharging on a Chevrolet Niva

Turbine for Chevrolet Niva The second method of tuning the power plant of a Chevrolet Niva is to install a turbocharger.
Moreover, this method allows you to significantly increase power and also increases torque. Turbocharging provides significantly better filling of the engine cylinders with air due to forced injection.

With this tuning option, you should carefully select a turbine, otherwise the positive effect of its use may be significantly lower than expected.

Tuning in this way allows you to achieve an increase in engine power by 30%. At the same time, turbocharging only has a positive effect on fuel consumption, since it is reduced. And the increase in power is achieved due to better fuel combustion and ventilation of the engine cylinders.

Tip 9: How to increase carburetor power

A carburetor is a special device in the power supply system of carburetor engines, which is designed to mix air and gasoline, which creates a combustible mixture. In modern cars, carburetor systems have been replaced by injection systems.

You will need

Instructions

1. In order to achieve maximum power, the carburetor at the inlet (drivers call it a “huge hole”) must have minimal resistance, since otherwise it will be difficult to achieve a good mixture and fill the cylinders at high and medium cycles. However, when the carburetor throttle valve is sharply opened, the speed of air flow and vacuum in the diffuser decreases significantly, and the amount of fuel sucked in decreases, causing the combustible mixture to become leaner. Leaning of the mixture leads to the fact that at low cycles the power tends to zero (this fact becomes more noticeable with huge D of the main diffusers).

2. By installing a standard SOLEX 073 carburetor, you get a wonderful increase in high and medium cycles, but at the same time increase fuel consumption, and besides, there is a failure in low cycles. Carburetor tuning in this case consists of increasing the flexibility of movement in high and medium cycles, achieving filling in low cycles, as well as in transition modes.

3. Increasing carburetor power is more important than simply replacing old jets with new ones with a huge cross-section. This, in addition to everything else, is a metamorphosis of calibration data, the “filling” of the carburetor, as well as the introduction of additional systems into the design of this device. To do this, drill additional metering channels in the carburetor body, then equip the carburetor with additional equipment and configure this device.

Note! To achieve maximum power on a sports car, several carburetors should be installed at once.

Helpful advice The uniformity of the distribution of the fuel mixture among the cylinders largely depends on the intake manifold. Often the reason for the uneven separation of the mixture lies precisely in the design errors made when designing the collectors. In order to solve this problem, it is enough to remove part of the partitions located between adjacent channels.

Methods for tuning a VAZ engine and

It is believed that the main goal of engine tuning is to increase the power of the car. But this is only one of the benefits that the owner of a Niva receives. In addition to an increase in torque, increased dynamics and maximum speed, driving characteristics and controllability are improved, engine efficiency increases, and fuel consumption decreases. A positive point is the increase in engine life.

Tuning the VAZ 21214 (21213) engine can be divided into two directions:

• Mechanical modification of the engine (correction of the geometry of the power unit);
• Chip tuning (software upgrade of the ECU) is possible only on injection modifications of the SUV.

In the first case, to improve technical characteristics, direct intervention in the vehicle systems is necessary.

Chip tuning is carried out by flashing the settings of the electronic control unit. The process takes from 30 minutes to 1 hour, but requires knowledge of the software and the features of working with it.

Content

The most popular and widespread SUV of domestic origin can be called Niva 4x4. This car has been produced for many decades, once designed as the main transport for residents of difficult rural areas. Even with such serious competition associated with the emergence of a large number of different foreign cars, the model is in demand. This is primarily due to the relatively low cost and good cross-country ability of the vehicle. However, in technical terms, the SUV has long been outdated and is inferior to many analogues. That is why we will take a closer look at tuning the Niva 4x4 engine, increasing power using the most common methods.

Doing the work yourself

The low wear resistance and efficiency of an SUV engine of Russian origin determines that it is practically impossible to do without mechanical modifications. Many people call such work a change in geometry.

The internal combustion engine installed on the vehicle in question can have many systems modified. Experts recommend starting with upgrading the carburetor. This is due to the fact that due to the use of imperfect production technology, its efficiency is very low. Modernization is carried out as follows:

1. To begin with, it is recommended to replace the nozzle. The factory version is installed with 1 cam, but should be installed with 2 cam.
2. The pump accelerator should be updated.
3. All sharp corners that could cause turbulence in the air flow are removed.
4. Some craftsmen also clean accessible surfaces, reducing their roughness. Due to this, the efficiency indicator is significantly reduced.

Insert: Important: It is important to clean the carburetor structure from carbon deposits and dirt. To do this, use gasoline or a rag. If the dirt has become too deeply embedded in the surface, you can use special cleaning products.

Experts do not recommend chipping a naturally aspirated engine. You can further increase engine power if you try to increase the piston stroke. This can be achieved by installing another crankshaft with a stroke of 84 mm, suitable for the VAZ 2130

. The piston has a diameter of 82 mm, but the piston pin must be offset by 2 mm. After this, the working volume will become 1.8 liters.

In the future, if you bore the block to 84 mm. with the same crankshaft, the volume will become 1.9 liters. But that’s not all, in the future you can increase the filling capacity of the working cylinders. This is achieved by boring and installing valves with an increased diameter of their plates. This operation is quite complex and requires special equipment. It is also advisable to use lightweight connecting rods and then you can have about 100 horses at the output.

Lubricant supplied through the oil pump extends engine life. To improve the performance of the oil pump when tuning the Niva engine, you need to take another pump and cut off part of the housing with the parting plane from it. The thickness of this “pancake” should be about 11 cm. Using milling, cut off the excess and leave a thickness of 10 mm.

Next, do the following to remove chamfers on the edges of the teeth:

1. We compress, that is, remove, the drive gears.
2. We trim one of the gears by 0.75 mm on each side.
3. We cut the second gear to 11.5 mm (after trimming).
4. We repeat the operation with the remaining gears (driven).

This car is distinguished by its simplicity of design, easy accessibility to all components and mechanisms, as well as its increased reliability.

Tip 2: How to bore a VAZ engine

You will need

Instructions

1. Boring a new engine makes no sense, except for those cars that are being prepared for participation in sports competitions. In all other cases, the cylinder block is bored during a major overhaul of the power apparatus.

2. Due to the fact that the cylinder block is bored using special industrial equipment, during advance preparation for this process, the engine is removed from the engine compartment of the machine.

3. After completing this task, the motor is completely disassembled, and after this, all the parts from which it was recently assembled are checked.

4. The “bare” engine cylinder block is delivered by auxiliary transport to the workshop to an expert in boring the specified parts. The master, after researching and performing the necessary measurements of the internal surfaces of the cylinders of your block, will give recommendations on obtaining a repair piston group of a certain size, which, after purchase, is delivered to him in the workshop.

5. After boring the cylinder block, the engine is assembled, after which a thorough repair of the engine is considered complete, and as a result of the repair, the power unit is endowed with an increased displacement and acquires increased power.

Third step: flashing the ECU

The most inexpensive way to increase the power of an off-road SUV, because chip tuning is a software modification and does not involve technical intervention. Replacing and adjusting ECU software is the essence of flashing. In this way, it is possible to change the operation of the electronic control unit, adjust the fuel supply and reduce its consumption, due to the engine’s performance in terms of power and dynamics. You can increase engine power by about 15% just by chipping.

The main ways to help increase strength indicators

The most effective and common are:

• The geometry of components changes due to the replacement of factory-installed engine parts
• The so-called chip tuning, the electronic control unit is reflashed
• Turbocharging is installed

All of the above methods are associated with significant financial investments, and help the engine become more dynamic, while increasing its power.

Let's look at all the methods in more detail

Carburetor modernization is a common Niva tuning option

The carburetors installed by VAZ are, to put it mildly, low in efficiency. That is why many people start tuning by changing this element. The features of the work carried out include the following points:

• The pump accelerator nozzle is being updated. It often causes air turbulence, which reduces the efficiency of mixture enrichment.
• In almost all cases, a jet with an indicator of 1 cam is replaced with 2 cam. This also allows you to significantly increase the efficiency of the carburetor.
• It is recommended to clean all unevenness and roughness, as this leads to increased air resistance during operation. For this, files and sandpaper are used.
• The structure should also be cleaned of various soot or other combustion products. This may require a special cleaning agent. Some craftsmen use special baths to remove dirt.

In the case where an injector is installed, it is almost impossible to carry out modifications yourself. Only a professional who knows the features of such a design will be able to change the basic indicators to increase power or reduce consumption. Self-tuning in this case can lead to serious malfunctions.

Tip 7: How to increase the octane number of gasoline

There are two ways to increase the octane number of gasoline: simple - by adding anti-knock agents (special additives) to it, and difficult - using a special technology that will increase the cost of the product. It is possible to “make” AI-92 from AI-76 gasoline, and AI-95 from AI-92. However, this also has its negative side. Low-quality fuel at unknown gas stations, where the octane number is unnaturally increased, leads to serious and expensive car damage.

You will need

Instructions

1. Add MTBE (methyl tertiary butyl ether), which is a flammable colorless liquid with a specific odor, to the gasoline. This is one of the means now especially used to increase the octane level. MTBE has a high octane number and is non-toxic. When adding 10-15 percent to gasoline, the increase will be approximately 6-12 units. Many high-octane gasolines are produced using this or a similar ether-class additive. The disadvantage of MTBE is its high volatility, because in hot weather it can evaporate from gasoline.

2. Add alcohols (ethyl and methyl) to gasoline. Say, a 10 percent addition of ethyl alcohol to AI-92 increases the octane number to approximately 95 units. In addition, the toxicity of exhaust gases is reduced. But the use of alcohols leads to an increase in intense vapor pressure. This may contribute to the formation of vapor locks in the fuel system pipeline. In addition, an important task is the excellent solubility in water and hygroscopicity of ethyl alcohol. This requires special storage conditions for the mixture and periodic monitoring of the contents of the alcohol component. If this is not observed, water may appear in gasoline, and this leads to increased fuel consumption, poor combustion, and if its percentage is high, ice jams may appear in winter.

3. Add tetraethyl lead Pb(C2H5)4. TES is considered one of the best anti-knock agents. It is an oily, colorless liquid with a boiling point of approximately 200°C. The use of TES as an anti-knock agent began in 1921, and today it is one of the most effective and inexpensive means of concentration 0.05%. It gives the chance to increase the octane number of gasoline to 15-17 points. Tetraethyl lead is not added in its pure form, since during combustion it forms carbon deposits - lead oxide, which is deposited on pistons, valves and other parts. To remove it from the combustion chamber, ethyl bromide, dibromopropane, and dibromoethane should be used. When burned, they form volatile compounds with lead, which are easily removed from the combustion chamber. A mixture of thermal power plants with these components and a special dye is called ethyl liquid, gasoline with such components is called leaded. Today, the production of leaded gasoline is prohibited because it has a high degree of toxicity. Lead, accumulating in the body, causes multiple sclerosis because it is poisonous. Leaded gasoline is prohibited for use in vehicles equipped with a catalytic exhaust gas converter. They are damaged when the engine is running after a few hours. Antiknock agents are also isooctane, neohexane, isopentane, benzene, toluene, and acetone.

How to find out the power of a car engine by engine number

This is the most popular type of tuning, regardless of whether you have a Chevrolet Niva or some kind of Pajero Sport.

By changing the appearance, you can easily and sometimes relatively inexpensively distinguish your standard Niva from the gray, monotonous stream of cars.

• Body kits and sills. Partially decorative and practical modification. Increases dimensions, gives solidity, simplifies getting into and out of the car when installing the same lift kit;
• Radiator grille. Simple, beautiful and original. There are many ready-made radiator grille options available for the Niva from Chevrolet, although if you wish, you can make it yourself from available tools and materials;
• Optics. Installing new optics, front and rear lights helps improve the quality of visibility at night. It will also be useful to mount DRLs and fog lights if they are not available as standard;

• Anti-gravel coating. It does not greatly affect the appearance, but protects the body from damage caused by gravel and all those delights that lie on the roads or fly off from cars in front;
• Painting. The body can be painted partially or completely, using the popular airbrush method;
• Wheel disks. An integral component of any tuning. This is where you should start. If you don’t have the money to buy a new set, and the old one doesn’t look very good, use the powder painting method;

Replacing engine components

If we consider the Niva in relation to the new years, then we should take into account that engine tuning comes in two options:

Recently, chip tuning has become very popular, which allows you to significantly increase the power indicator in the shortest possible time. However, this tuning method should be treated with some caution, which we will discuss in more detail later.

Not all SUVs of domestic origin have an on-board computer. At the same time, we should not forget that some on-board computers are in poor condition and in fact do not affect the operation of the engine.

When considering this tuning method, we note the following points:

• You can increase the power by about 10-30 hp. or more. It all depends on what parameters were set before tuning.
• It is recommended to entrust this type of work to specialists who provide services in this field of activity. This is due to the fact that incorrectly carried out chip tuning can cause various problems with engine operation.
• The technical condition of the internal combustion engine design largely determines whether chip tuning can be carried out. If the motor is in poor technical condition, then increasing the load causes rapid wear. Therefore, if the process in question is carried out correctly, a complete diagnosis is first performed.
• As a rule, the automaker sets minimum power values, leaving a margin. If chip tuning has not been carried out previously, the programmer will be able to configure the engine to increase its power. If the modification in question has already been carried out previously, it will no longer be possible to carry it out again.

In general, we can say that chip tuning is carried out in many cases when it is necessary to increase engine power. However, in order to significantly increase traction, it is necessary to improve the geometry.

Modernization of the off-road features of the Chevrolet Niva contributes to a significant expansion of the vehicle’s capabilities:

• the upper shock absorber mounts are strengthened;
• The fastening of the upper bolt holding the front axle gearbox is being modernized.

Additionally, you can install a hydraulic power steering control, double or gas springs instead of the standard ones. All this is quite expensive, but if you do this tuning, you will never regret it.

The appearance can be significantly changed using the following details:

• front and rear bumper protection;
• thresholds;
• spoiler;
• kangurins.

You can see how tuned Chevrolet Nivas look in the photos or video clips attached at the end of the article.

Engine VAZ 21213 1.7 l. carburetor/injection (21214) in-line 4-cylinder with overhead camshaft, Niva timing belt has a chain drive. Based on the 214 engine, the VAZ 2123 engine is produced for the Chevy Niva; the differences in adapting the block for installing a pulley in the engine compartment and mounting attachments are technically almost identical.

The main differences between the VAZ 21213 engine and the 2106 are the cylinder diameter is 82 mm, the cylinder head, the Niva 21213 engine block from the 2106 is smaller in height. Among the advantages of the 213 engine, it is worth noting the presence of a chain tensioner (no need to tighten it) and hydraulic compensators (no need to adjust the valves).

The simplest modernization of a Chevrolet Niva engine involves replacing certain parts. First you need to bore the sleeves. After this, you need to select pistons and special ring-shaped elements that have a certain size.

The next step is to equip the engine with a crankshaft with larger arms and smaller connecting rods. The result of the above actions will be an increase in engine volume from 1.7 to 1.9 liters, and, consequently, power will increase.

It is also worth thinking about increasing the volume of fuel going to the cylinders. To do this, the cylinder head is modified, namely, the intake and exhaust ports are bored, the valve is replaced with a larger one, the valve seats are bored or completely changed.

Experts' opinion

Gena. The engine can be called the real heart of the car. Many people recommend starting tuning with it, since only by improving the engine can you make the car run over bumps and fords. I will say right away that the task is not an easy one. Improving an engine can take a lot of time and effort. Therefore, you should be prepared for difficulties.

Stanislav. The Niva is a good car, even one of the best produced by the domestic auto industry. However, it has many disadvantages, among which we note the low engine power and its unstable operation. That is why, almost immediately after purchasing this car, I immediately upgraded the engine.

https://www.youtube.com/watch?v=ytaboutru

Vitaly. I decided to modify the standard Niva engine. There was a lot of work, so I decided to entrust it to professionals. Although I myself have some experience in engine repair, I did not undertake its complete modernization. As a result of the work done, the guys increased the power by 60 hp. Of course, not an impressive result, but still the traction has increased significantly.

Geometry improvement work

Due to the low engine efficiency and low wear resistance, mechanical tuning of the Niva 4x4 engine is almost mandatory. Such work is called work to change the geometry of the power plant. You should start modifying the power plant by upgrading the carburetor. We do the following:

1. We change jets with an indicator of 1 kam to a jet with an indicator of 2 kam;
2. Renewing the accelerator pump nozzle.

If there is dirt or carbon deposits in the carburetor, we clean it manually. To do this we need a rag, gasoline and physical strength. If the dirt is very stubborn, a high-pressure cleaner or other device designed for washing the car will help. You can also use special “baths” to remove dried dirt from parts. In this way, the fuel supply to the gas distribution mechanism can be significantly improved.

If you are the owner of an injection Niva, then independently modifying the injector is unacceptable. Only a professional with knowledge of software can perform such tuning of the Niva engine.

Tip 5: How to increase octane number

Gasoline with a high octane number is produced by two methods: using difficult technological operations, which increases the cost, and by adding anti-knock additives. From 76 gasoline it is absolutely possible to obtain 92, from which fuel with an octane number of 95 is easily made.

You will need

Instructions

1. Methyl tert-butyl ether, which has the form of a colorless, flammable liquid with a specific odor, is especially widely used. It is characterized by low toxicity, but has a high octane number. When adding 15% ether, the octane number increases by 12 units. Many gasolines are produced using just such an ether class additive. MTBE is highly volatile, which makes gasoline easier to evaporate in hot weather.

Do-it-yourself turbine installation in Niva

Engineers have long been of the opinion that it is the turbine that provides a surge of greater power due to the active enrichment of the mixture. It is worth considering that installing a turbine is not a complicated modification, but the high cost of the compressor may become an obstacle to such tuning.

The design of the installed turbine is usually quite simple:

• The central part is a shaft that receives rotational motion.
• The impeller of the supercharger and turbine is installed on the shaft.
• The exhaust gases become a kind of drive, which also makes it possible to significantly increase the efficiency value.

The fact that the shaft does not receive rotational motion from the crankshaft itself or related mechanisms can significantly increase the efficiency of the installation and its power. It is possible to install the turbine yourself, but due to its relatively high cost, about 40,000 rubles for the simplest model, it is better to entrust the work to professionals.

We will improve the exhaust system

Since the exhaust system can increase the power and efficiency of the engine, tuning the VAZ-2121 engine includes the installation of modern exhaust and intake manifolds.

With their help, the process of air supply and exhaust gas removal will be optimized, and the efficiency of the power plant will become higher. To increase engine power, it makes sense to install a resonator from the muffler. With it, exhaust gas removal improves, and the running engine acquires a beautiful bass sound.

Tuning the VAZ (Niva) engine also includes moving the muffler further to the rear axle, when almost the entire exhaust system is dismantled. In this case, the resonator can be installed from any car, for example, from a Moskvich.

Oil pump work

Lubricant supplied through the oil pump extends engine life. To improve the performance of the oil pump when tuning the Niva engine, you need to take another pump and cut off part of the housing with the parting plane from it. The thickness of this “pancake” should be about 11 cm. Using milling, cut off the excess and leave a thickness of 10 mm.

Next, do the following to remove chamfers on the edges of the teeth:

1. We compress, that is, remove, the drive gears.
2. We trim one of the gears by 0.75 mm on each side.
3. We cut the second gear to 11.5 mm (after trimming).
4. We repeat the operation with the remaining gears (driven).

Let's start working on the body. To do this we do the following:

1. We release the driven gear axis from the housing.
2. We form a longer axis from the drive roller.
3. We insert the resulting axle into the body.
4. We press the narrow gear onto the second drive shaft.
5. Press on the wide gear.
6. We fix the wide driven gear in the housing.
7. We install a narrow gear into the housing.

The lower classes can't, the upper classes don't want to

I won’t bother you - I have a modified 105 hp engine under the hood. with a maximum torque of 160 N.m versus 79.6 “horses” and 127 N.m for the standard car.

Who is Volodya? The head of the LSGA engineering center, Vladimir Sharandin, is a specialist in engine development and has been a good friend of mine for almost two decades.

The idea to start working on Niva was born spontaneously. We discussed another car, but the conversation itself led to the all-wheel drive of the GM-AVTOVAZ joint venture. What does Niva lack in driving disciplines? Of course, engine vigor. Especially when driving on highways. Off-road, the lower row of the transfer case helps out, but on the highway... The car frankly falls out of the modern flow. This is especially noticeable during acceleration. Trucks have now become fast and overtaking them on Niva is quite problematic. You have to fire up the SUV ahead of time, calculate the situation almost to the horizon and, without resetting, so as not to lose speed, perform a series of overtaking. Dangerous? Yes! This is the problem Vladimir undertook to solve.

It is clear that no one was going to make a youth car for street racing - the device was not for such an audience. It was about safety: the fight against prolonged overtaking and at least some reserve of agility under the gas pedal. At the same time, it was necessary not to overdo it. It was necessary to maintain all the best off-road qualities, not to overload the transmission with excess torque, keep fuel consumption at the same level and fit all this into a budget feasible for Niv owners. Oh yes, a mere trifle, the cylinder volume is standard - no work on the block, pistons, connecting rods or crankshaft. We don’t touch the bottom of the engine, we only modernize the top: cylinder head, exhaust, intake.

The Niva LSGA with a 105-horsepower engine has not lost its best qualities on off-road. The Niva LSGA with a 105-horsepower engine has not lost its best qualities on off-road.

Mechanical modification of the Niva engine

For a 4x4 class car, which is the Niva, mechanical tuning is mandatory. The reason is the low performance of standard components in terms of geometry and wear resistance.

Engine tuning should begin with improving the carburetor. Here you should replace:

• Jets. Instead of 1 camera (t110 in ZD150), 2 cameras are installed (t125 in ZD135);
• Accelerator pump nozzle.

Be sure to clean the carburetor from carbon deposits. This can be done manually using a rag, gasoline and physical force, high-pressure washers designed for home car washing or specialized baths for cleaning parts. All of the above will allow you to debug the fuel supply mechanism to the timing belt (gas distribution mechanism).

Mechanical intervention in the injector is unacceptable; its adjustment is carried out using special equipment and software.

The second stage is tuning the timing belt and other mechanical components of the engine. You should immediately start correcting the geometry of the power unit. To do this, it is necessary to increase the diameter of the valves. It should be noted that sealing them increases motor power by up to 10%.

The same operation is carried out with the pusher wells of the intake and exhaust channels. This entails replacing the pusher itself. It is recommended that its diameter be at least 1 mm. This upgrade is very important for the 4x4 layout. The next step is to replace the injectors and control unit.

You can increase engine power by replacing the standard crankshaft with an advanced modification, as well as installing new piston rings. Installing a new crankshaft will give increased stroke to the pistons. In this case, they must be bored. Although many experts argue that this significantly increases fuel consumption, this operation cannot be avoided when replacing the crankshaft. All of the above operations also add power to the motor.

All of the above will significantly improve the technical performance of the Niva and reduce the wear of spare parts. The smoothness of the ride is also improved.

How much will such a service cost from a specialist?

The price depends on whether the car owner will pick up the controller, in this case the cost will be 12,000 thousand rubles. If the controller remains with the master, then this service will cost the driver 10,000 thousand rubles. And for the Niva 21214M version the cost will be 7,000 thousand rubles. Of course, in different regions and cities, prices for chip tuning may increase or decrease, but not by much.

If you still decide to do engine tuning yourself, be sure to watch this video:

Chip tuning of a Chevrolet Niva significantly increases its capabilities, but do not forget that only a professional can perform this procedure efficiently. If you are confident in your abilities and (or) want to save a tidy sum, you can try tuning the car yourself, but the risk of serious damage rests entirely on your shoulders.

Many of those owners who drive a Niva Chevrolet note one, but quite significant drawback on this car - the rather low final engine power. Due to the fact that the car has increased cross-country ability, its weight is quite large, and 80 “stock” horses are simply not enough.

Let's sum it up

There are quite a large number of ways to modernize the Niva engine, all of them have their own specific features. It would seem that replacing consumables with better ones is an insignificant upgrade, but it allows you to increase engine power by several tens of horsepower. More significant upgrades also improve the technical qualities of the engine, but do not forget about the increase in load, as a result of which its service life is reduced.

It is recommended to entrust serious engine modernization to professionals. This is due to the fact that even minor mistakes made can cause rapid wear and tear of the structure and render it unusable. If the engine is in poor technical condition, then attention should be paid to the possibility of completely replacing it: the amount of work and costs are reduced. The motor must be not only powerful, but also reliable, which should not be forgotten.

Niva with turbine

The most common way to add power to an engine is to install a turbine or compressor, which will significantly increase the volume of air entering the power plant.

Installing a turbine is not a complex tuning solution, since the turbine itself has a fairly simple structure. The supercharger and turbine impellers are mounted on the same shaft, and the exhaust gases are the drive. Thus, we can observe the most efficient use of energy from combustion products in a car. The absence of interaction between the crankshaft and the turbine shaft also increases the efficiency of the power plant.

In general, the Niva engine can and should be modified, and then your car will become more powerful and last much longer. This is what we should strive for!
