Engine from a foreign car for a VAZ 2115 - how to install, which one to install

If you drive a VAZ-2106, you know that this car's original engine has relatively little power. In addition, such engines are short-lived. Therefore, many owners of these cars at some point in time decide or are faced with the need to change the engine. What engine can be installed on the VAZ-2106? Theoretically, any engine that fits under the hood is suitable for such a car. Since there is quite a bit of space under the hood of this car model, the engine must be chosen from similar small cars.

When installing a new unit, you will not only have to redo the brackets and perform a number of other procedures, but also go through the car registration procedure again. When replacing engines, you will need to re-register the car with the traffic police. This need is due to the fact that there is a license plate on the engine block, which must be registered in the vehicle’s registration certificate.

Craftsmen often install engines from cars such as:

• BMW;
• Fiat;
• Priora.

When choosing, it is worth considering the permissible power of the unit. It should not be too powerful, otherwise there is a risk of destroying the brake system and breaking the bridge. Also in this case, the car’s suspension may not be able to cope with the heavy load.

It is better to buy the engine straight from the gearbox. So all you have to do is adjust the cardan and connect the gearbox to the axle.

Reworking the 2115 engine - reasons and difficulties

Generally speaking, replacing the motor is an undesirable procedure. The reason lies in the fact that the engine installed at the factory is the most optimal for this particular car - everything has already been thought out by the designers and engineers. True, the results obtained do not always satisfy motorists.

So, it’s worth comparing at least the total resource of domestic and foreign engines. For the first (specifically for the VAZ 2115) it is 250,000 kilometers, and for the second (similar in all other parameters) - 500,000 kilometers. Even this fact alone makes drivers think about installing an engine from a foreign car in a VAZ 2115.

It should be remembered that the problem of installing and altering the engine is not the only one that will have to be faced. Most drivers are not stopped by it, but by the enormous difficulties of further registering such a modified car with the traffic police.

Speaking about the choice of engine, we can answer very briefly - you can install absolutely any engine that fits in the engine compartment. True, in most cases, a bunch of other mechanisms will have to be replaced, as a result of which little will remain of the original car (except for the body and interior).

That is why you should give preference to the most compatible engines. Another, no less optimal option is to upgrade the original engine. It will be much cheaper and will not cause any problems with the police.

How to improve the power of a standard VAZ 2110 engine

We can talk about improving power in more or less budgetary ways only in the context of VAZ injection engines. However, there are not many dozen carburetor cars left on the roads. Usually, VAZ 2110 owners who don’t have enough power from the stock engine simply want to do chip tuning of the ECU and get a serious increase in power, but it’s not that simple.

It should be taken into account that VAZ designers saved a lot when developing and assembling these engines. This means that the intake and exhaust will not be the best in their class, the fuel supply system will have its limitations, and some sensors, even after tuning the ECU, will not fully carry out the computer’s instructions.

For normal tuning you will need to perform the following set of actions:

1. Air filtration system. It is worth installing a zero resistance filter and allowing the engine to breathe more easily.
2. Throttle valve. There is no point in modifying it in any way. You can look on the market for a new damper with a larger hole diameter. This will allow you to immediately get a small increase in power.
3. Inlet receiver. It’s worth replacing it with a more efficient one, but you can’t save money here. So, if you want to increase the power of your car on a budget, skip this point.
4. Tuning camshafts will also not be cheap, but it is worth undertaking for good results. In the stock version, the shafts do not cope with the tasks very effectively, and replacing them with tuning parts will clearly add power and torque to the motor.
5. An exhaust manifold. If air intake is already easier, the engine also needs to breathe out easier. Sports-type exhaust manifolds for the VAZ 2110 engine will greatly change your impression of operating a Russian car.
6. Computer. And only at this stage can you touch the ECU settings in the Ten and adjust all the parameters to the new parts. It is important to manually configure all the necessary parameters after installing the above elements.

By the way, the increase in power can be quite serious. Up to 30-40% of stock values. But, of course, it is worth considering that tuning has many nuances. The service life of the engine will decrease, you will have to look into the piston group more often, change the rings, and treat the cylinder head. Also, consumption will obviously increase, miracles do not happen. But the machine will start to bring a lot of pleasure for relatively little money. If you wish, you can continue to work with the engine more deeply and get even more interesting changes. But remember that tuning engines with mileage over 200,000 km is deadly for such engines.

Engine dismantling process

Of course, the best option would be to replace the engine in a fully equipped workshop, but if this is not possible (and you really want to do tuning), then you should have the following minimum set of equipment:

• winch, hoist or hydraulic lift;
• shoes;
• jacks;
• cart;
• knob with a set of heads;
• spanners;
• screwdrivers.

Dismantling is carried out in the following order:

1. The car is stopped using a hand brake and shoes, which should be placed under the rear wheels.
2. Place the front wheels on jacks.
3. With the hood open, disconnect the “mass” terminal and all small hoses and tubes suitable for the engine.
4. Seal the pipe inlets to the engine to prevent them from clogging.
5. Disconnect the throttle cable from the throttle pipe and bracket.
6. Disconnect the air intake hose together with its bracket.
7. To dismantle the air filter - to do this, use a sharp blade to cut off the three rubberized supports, due to which it is attached to the engine body.
8. Remove the hoses leading to the receiver.
9. Disconnect the hose intended for purging the adsorber from the nozzle.
10. Remove the wires suitable for the pipe, the ignition module, as well as all others connected to the internal combustion engine.
11. Remove the engine splash guard by unscrewing the mounting bolts.
12. Drain all the coolant by removing the plugs on the cylinder block and radiator (while opening the reservoir cap).
13. Drain the oil by unscrewing the plug cap on the gearbox.
14. Disconnect the clutch cable.
15. Secure the hooks of the lifting device to the eye bolts located on the gearbox and on the cylinder block, and then remove the engine.

Installation of the new motor is carried out in exactly the same order, but in reverse order. Also, it is important not to forget to connect the wires of all sensors to the correct connectors and refill all technical fluids that were drained during dismantling (coolant and oil).

Despite the fact that some car enthusiasts advise first removing the gearbox and then removing the engine, it is strongly recommended to remove the engine together with the gearbox.

Major renovation

As an alternative replacement option, you can consider major repairs or tuning. Repairing your original engine will allow you to save a lot of money. And as a result, you will receive a unit that will be in no way inferior to the new engine you purchased. If it is necessary to increase power, it is enough to install larger cylinders and bore the block. You can also increase the compression and install a turbine. Such tuning will make your car a real “beast”. To extend the life of the power plant, you need to install high-quality parts and use good quality oil.

The easiest way to increase power is to bore the power plant by 3 mm for an 82 mm piston. To get a more torquey engine and to further increase the volume to 1.8 liters, you will have to increase the piston stroke to 84 mm.

One of the advantages of repair and tuning is that there is no need to re-register the car. You can spend the saved money, for example, on improving the braking system, increasing comfort, etc. You don’t have to do all this yourself. Even if you use the services of a car service, it will cost less than buying and installing a new engine.

Which imported engine should you prefer?

Now let's move on to the main question - what engine can be installed on the VAZ 2115? Answering this question, I would like to remind you once again - you should choose only the one that can be installed without modifications or with a minimum number of them.

These imported engines include engines from:

• AUDI-80;
• BYD F3;
• Alfa Romeo;
• Chery Amulet;
• Chevrolet Aveo;
• Ford Focus;
• Fiat Bravo;
• Geely CK2;
• Geely MK1;
• Honda Civic;
• Daewoo Lanos;
• Opel Astra;
• Hyundai Accent;
• Opel Corsa;
• Opel Astra Kadett;
• Opel Astra Vectra B;
• Seat Ibiza;
• Mazda 323;
• Mazda 626;
• Peugeot 205;
• Peugeot 405;
• Toyota Supra;
• Renault Logan;
• Volkswagen Golf;
• Volkswagen Jetta.

All of the listed engines can be installed on the 15th VAZ with a minimum of alterations to other mechanisms, in most cases - without any alterations at all. This will help save not only effort and money for additional work on replacing units, but can also save a lot of nerves when registering a car with the road inspection (although registering such a tuned car will still be a very big problem).

That is why, before deciding which engine is suitable for a VAZ 2115 from a foreign car, it is better to think again about tuning an existing, original engine. There are quite a few ways to increase its power and service life without replacing it with another, and all of them are completely legal from the point of view of the law.

Number of valves per cylinder

Initially, all engines were equipped with two valves per cylinder: one intake and one exhaust. Such motors are simpler to design, but less efficient; one might say they are a thing of the past. Modern engines are usually equipped with four (and sometimes five) valves per cylinder, which makes it possible to fill the cylinder with the combustible mixture and remove combustion products much faster. As a result, power and torque increase , and fuel consumption decreases , so when choosing an engine, pay attention to how many valves it has per cylinder .

Possibilities for re-equipping a VAZ 2107 car

To improve the capabilities of their car, drivers often use tuning of the VAZ 2107 engine, replacing the standard power unit with a motor that has more power. To carry out this activity, it is necessary to consult with qualified specialists. When re-equipping a car, you need to consider the following possibilities:

1. Is the newly selected motor suitable for the “seven” in size and weight?
2. Is it possible to mate the new engine with the transmission of the car?
3. Is this motor compatible with each of the systems of this car?

What to put?

Indeed, the most important issue among VAZ 2109 owners is the range of engines that may be under the hood of their car.

Let's look at a few of the favorite solutions, which in most cases are found among those who decide to change the engine on their own VAZ 2109.

Gas is a more affordable alternative to gasoline, which will allow you to save money in the future at gas stations. This substitution is called easier. But you should take into account the fact that such a replacement will pay off only if the car is used frequently, and you will have a gas cylinder in the trunk. Such work can only be done by professionals with the appropriate qualifications and permits.

VAZ injector 1.5 liters

A good candidate to extract more power from your upgraded car. The injector is stronger, it requires less fuel, and provides the best dynamics. But in practice, changing engines from VAZ to VAZ is not the best solution, since there are a lot of options among more reliable, massive cars imported from other countries

Engines from Priora and VAZ 2112

Good Russian options that will simply fit into the space for the engine of your nine. Excellent performance, a good opportunity to transfer not only the engine, but also the gearbox itself

1.5 liter engine from Honda Civic

Here we are talking about 1.5-liter engines with a capacity of 92 horsepower of the 1991-1995 standard. Injection engines of that generation perfectly fit the dimensions of the VAZ 2109 engine compartment and have good technical features. A kind of improved variation of the previous version

Engines from Opel

Vectra engines of 1.4, 1.6 and 1.8 liters have proven themselves well. The engines, although old, are fast, quite massive, and relatively economical. Their main advantage is an affordable price with good build quality. If you find a decent German engine of any of the presented volumes, your VAZ 2109 will work much better compared to the factory engine

Motors from Mitsubishi Lancer

1.5-liter injection engines with a power of up to 100 horsepower are to the taste of many. Excellent dynamics, high-quality assembly, pleasant efficiency. Finding such a motor is not at all difficult, and there shouldn’t be any huge problems either.

Nice swap option for a fast, fun, reliable Korean engine

. The only important nuance is that the box from the nine does not correspond to the features of the engine from the Korean, so you will have to change everything together

My partner In a couple of days I’ll post how she rides! My friend Vova's channel, guys, support it.

VAZ 2110 WITH SUBARU WRX-STI ENGINE is a 1.6-liter engine with 16 valves and a power of 90 horsepower. You will find such engines on the Doblo model. There are quite a lot of them at car wrecking yards, so there shouldn’t be any problems finding them.

Torquey, quite powerful, dynamic engine with a good margin of safety. A good solution for our roads. Japanese quality is not much inferior to the presented analogues from Germany. At one time, engines for the 626 model received many positive reviews, which is why their installation on the VAZ 2109 is recommended by many experts

Replacing a motor is a complex operation that requires the participation of an experienced specialist. It is strongly not recommended to change the engine yourself in a garage environment.

Underwater rocks

There are several important, interesting and simply useful factors that must be taken into account when making a decision regarding replacing the engine on a VAZ 2109.

1. If you approach the issue from a practical point of view and take into account the ideal compatibility of parts, then your best solution will be to install an alternative engine. But often replacement is carried out in order to increase productivity and increase engine power. In this case, you have to look for alternatives among the VAZ, Lada or imported cars.
2. When replacing an engine from a 9 with a newer engine from the same model, you will not be able to install air conditioning. No, it is quite possible to carry out the installation, only then the power of the already not very playful standard engine will noticeably drop. In addition to the loss of power, you will have to change the generator to a more powerful one, since the factory generator will also not be able to handle the climate control equipment.
3. engine
   is good because it fits perfectly with the standard gearbox from the VAZ 2109. The same can be said about the Priora.
4. When increasing engine power, you will need to modify the brake system. Otherwise, the braking distance will increase significantly, and you will not be able to stop the car in a timely manner. So it is a mandatory step to replace standard discs and pads with more durable ones. If possible, replace the rear drum brakes with disc brakes.
5. You will have to make changes to the cooling system. The radiator must be changed to one that matches the characteristics of the new power unit. If its power is higher than the engine from nine, the parameters of a standard radiator will probably not be enough.
6. Documentation. Not long ago, the country passed a law that abolished the need for an engine number during registration. That is, from now on, the engine is just a spare part, which is equated to the same generator, air filter or wheel, for example. Due to this, the demand for replacement engines has increased significantly. But you must have documents for the motor. When buying an engine
   secondhand, make sure that the owner has papers confirming ownership.
7. Origin. The lack of papers makes the motor quite potentially dangerous for you, since its origin is unknown. It is not uncommon to find engines that were removed from stolen cars.
8. Contract motors. The most optimal option from the point of view of your safety is purchasing a new engine. Contract engines are provided by specialized companies, where in addition to the unit itself, they provide you with a guarantee and all the necessary documents.
9. Re-registration. Decide for yourself whether you will register the converted car with the traffic police. Experts advise contacting the appropriate authority so that you can get a new motor. This way you can avoid many problems and misunderstandings on the roads when an inspector stops you.

Replacing the motor

ndash; the task is not easy

Tuning is not just about changing the appearance of a car, as many people think. In fact, revisions often concern the technical component. Someone makes changes to the exhaust system, changes elements of the factory engine.

But there is a more drastic, expensive and interesting option - change the engine. With the new engine you get different technical characteristics, increased power, increased maximum speed, better acceleration.

Replacing a motor is a fairly serious step that requires thinking through every stage, from choosing a new motor to the consequences that such work may result in.

Wiring diagram VAZ 2107 injection wiring

In the mid-90s, a massive transition of Russian models from a carburetor to an injection power system began. This requalification also affected the VAZ 2107 and 21074 cars. As a result, the model received new elements that structurally distinguish it from its predecessor:

• electric fuel pump. It takes fuel from the tank, maintaining constant pressure in the fuel line. The carburetor version had a mechanical fuel pump;
• fuel injectors that inject directly into the combustion chamber. Therefore, the fuel-air mixture is formed directly in the combustion chamber. On the previous modification, the mixture was formed due to the opening of the carburetor air damper;
• new engine control unit, which determines the moment of injection and forcibly performs it. The fuel mixture is forced into the cylinders by the injection system, while in the carburetor the fuel is supplied due to rarefied pressure after the valve opens.

Accordingly, the electrical circuit of the Lada has changed somewhat:

• a wiring harness block was added to the fuel frame;
• their wires were connected from the controller to the ignition system harness;
• radiator sensors and a fan appeared;
• the electric fuel pump was also connected to the circuit;
• The VAZ 21074 injector itself received sensors for mass air flow, oxygen indicator, crankshaft position, as well as a special valve in the line itself.

A VAZ with an injector type engine has fewer problems. Many electronic equipment control relays are quite reliable. However, the system is still not without its shortcomings. Some chargers are not friendly with the battery, the control unit for the electro-pneumatic valve sometimes malfunctions, and the light switch does not work when the front door is opened.

The electrical diagram of a VAZ 2107 with an injector will help you understand the description and repair. The following circuit is for models equipped with a 37.3701 generator.

↑ Design of the injection version of the VAZ-2107

The transition of the car to the injection version entailed design changes. Naturally, there is no distributor and carburetor.

The mechanical elements responsible for the functionality of the ignition system and the preparation of the air-fuel mixture have been replaced with efficient electronic devices. As a result, the electrical wiring diagram is equipped with additional engine compartment connectors.

• 29 – pressure control sensor and low oil pressure indicator.

The electrical circuit is made using single-wire wiring, like most modern cars. The other terminal with a minus sign is connected to the ground of the machine. The electrical circuit includes the electronic engine control system.

The injection version of the “seven” has an electric fuel pump that provides the proper pressure at the outlet. It is an electric motor whose blades pump gasoline under high pressure into the system.

The electric pump is located in the fuel tank; when the ignition is turned on, it builds up operating pressure, after which it supplies fuel directly to the injectors. The VAZ 2107i injector is equipped with 4 nozzles. They are controlled by a microcontroller.
