Replacing the cylinder head gasket VAZ 2107 is not as difficult as a responsible operation. At self service"seven" every car owner has to deal with this work. Internal organization engine is the same for the entire line of "classics", therefore, the order of advice on replacing the cylinder head gasket is equally applicable when repairing engines from the "first" to the "seventh" model. When to change gasket...
The VAZ 2107 car was created on the basis of the 2105 model. New sedan designed for 5 seats, was equipped with a 5-speed mechanical box. The car was launched into the series in the 82nd year.
Initially, a carburetor engine from a VAZ 2103 car was used as a power unit. Carburetor internal combustion engines were also installed on subsequent models and modifications. For export models 21073 a new injection unit has been developed. He had sufficient power, as well as efficiency. The engine displacement was 1.7 liters. Further, injectors began to be installed on all "sevens". It was over modern engine(VAZ 2107 injector) with a volume of 1.6 liters. This made it possible to ensure compliance with existing environmental standards.
Let's figure out what an injector is, see the principles of its operation, technical characteristics.
History and device of the injector
The debate about which of the systems is better among specialists and motorists has not subsided so far. But let's leave these disputes to professionals. And novice motorists just need to know how this system works and how it works.
It is not at all necessary that motorists will need this knowledge to self-repairs. However, knowledge is power. This knowledge is needed at least so that the novice motorist is not deceived by cunning mechanics from the service station around the corner.
The history of this device begins in 1951. It was then that the well-known company Bosch installed such an injection system on a 2-stroke engine of one sports car. Then, in 1954, the well-known and popular car manufacturer Mercedes also began to equip their engines with a new system.
The serial use of injectors began in the late 70s. Even then it was clear that this device works better than the usual carburetor systems.
As a result, injectors completely replaced their "ancestors". Everything modern cars equipped with such distributed systems, as well as direct electronic injection.
The principle of operation of the injector in the power system
The injection system is designed to deliver fuel by direct injection using an injector directly into the intake manifold of the cylinder. Therefore, cars with a distributed injection system are called injector.
The classification of the injection method depends on the principle by which the system works, as well as where the injector is installed, and how many of them are in the car.
All modern cars carry out fuel injection using a distributed system. That is, each cylinder has its own injector. The principles of operation are based on the signals of the microcontroller, which receives information from a variety of sensors. Then, according to this information, the controller either opens or closes the nozzles.
VAZ 2107 injector: device
In VAZ 2107 cars, a distributed injection system is installed. She works with electronic system engine control. It's called an ECU. It uses numerous sensors to control the supply and amount of air and fuel that enter the cylinders. Also, the ECU, if necessary, starts or stops the fuel pump, controls the formation of a spark on the spark plugs, and also corrects the ignition angles. In addition to all this, the ECU regulates the frequency with which the crankshaft rotates for Idling and also, if necessary, starts the cooling fan and controls the cooling system.
Scheme of operation of the injection power circuit on the VAZ 2107
There is nothing complicated here. This scheme should not cause any difficulties even for beginners.
First, the fuel system starts with a tank that stores fuel, and fuel filter. Then, using the fuel pump, the mixture passes through the filter to the fuel rail. A special pressure regulator is mounted on the ramp, which regulates the process of supplying fuel to the injectors VAZ 2107 injector.
With the help of this regulator, a pressure of 300 MPa is created, and excess fuel is sent back to the tank. The nozzles are opened and closed by means of electrical impulses that come from the electronic control unit. They are designed to provide simultaneous fuel mixture into the intake manifold of each of the cylinders with each revolution of the crankshaft.
How combustible mixture gets into the cylinders, depends on the time at which the nozzles are open. This time is regulated by the controller according to the information received from the sensors.
Sensors (VAZ 2107 injector) installed on the engine give all the information necessary for this. For example, the crankshaft sensor provides information on which the controller calculates the time between pulses for injectors. If the operating mode of the power unit is increased, then the system increases the opening time of the nozzles. The controller calculates the time based on information from the throttle valve, as well as the mass air flow sensor.
The ECU constantly monitors the voltage in the electrical network of the car, therefore, in the event of a decrease in voltage, the opening time of the injectors increases. All operating modes of the motor and injector are controlled by the controller. This ensures the adjustment of the composition of the fuel mixture and the operation of the nozzles on the VAZ 2107 "injector" car.
Ignition system
Traditional devices are not used here. As systems that provide ignition, the VAZ 2107 (injector) is equipped with one module, which consists of two coils, as well as electronics. There are no moving parts in the system.
How does the injection system work on the "seven"?
How much fuel will be supplied through the injectors to the cylinders is controlled by an electrical impulse from the ECU. The block calculates the amount of fuel that the engine needs, and also determines how long the pulse will be.
When the crankshaft starts to scroll, the very first pulse from the idle sensor causes the ECU to turn on all the injectors. The very first injection takes place every time you start. How long the pulse will last depends on the temperature.
When the driver turns on the ignition, the fuel pump relay starts and pressurizes the fuel line. Next, the computer checks the temperature and calculates how much air and fuel is needed to create the mixture, and then feeds it to the engine. VAZ 2107 injector, by the way, is more economical than its carburetor counterparts. This is achieved through a more accurate dosage of fuel.
Generator
VAZ 2107 injector, in addition to all these devices and sensors for the correct operation of the injection system, is also equipped with a generator. It is necessary to charge the batteries and power all consumers of electricity and the injection system as well.
How does the generator VAZ 2107 model work? The injector dispenses fuel into the cylinder, after which the car is set in motion. At this moment, the generator generates the necessary voltage to charge the battery and power the electrical equipment.
VAZ 2107: reviews
As for the reviews of the direct owners, they are, as always, very controversial. Many of the drivers and owners of this car complain about high flow fuel, on the low dynamics of the VAZ 2107 model. At the same time, they do not scold the injector. Also, many drivers say that they are satisfied with everything in the design of the car, and in the design and operation of the power system. Some do not like the products of the Russian automobile industry at all, so they scold domestic cars in every possible way.
Today, if not all, then most drivers appreciated injection system injection on merit. And many began to install injectors on conventional carburetor machines. Today, you can purchase a new or used kit that includes everything you need to run the system.
How much does it cost to install an injector on a VAZ 2107? The price of this upgrade is about 20,000 rubles. But such a replacement will definitely pay for itself in the future.
So, we found out how the engine and generator work on the "seven". VAZ 2107 injector is much better than its carburetor counterpart.
Engine for VAZ-2107 can be supplied both from domestic and from imported manufacturers.
This type of improvement of the base model is considered tuning, and if it is done by oneself, then one can earn approval and hear words of admiration not only from drivers, but also from those who have never driven a car. Confirmation of this - video:
Reviews are only positive:
- The boys are real craftsmen.
- Great CDs, love it.
- The engine is such that there are no words!
- Great job: the piston is exactly 100 in diameter.
- How cool they connected the box with the engine from the GAZelle and rear axle. Virtuosi!
- The guys are just handsome, they managed to do this with their own hands, which is not a pity to praise.
- In addition to what has been said, take some advice: it is worth putting the bumper on stronger and in general then the tuning was 100% successful.
For some future car owners, the question is more serious: which engine to prefer -? Let's hear what experienced drivers have to say.
Mikhail, 40 years old, is the owner of a VAZ-2107 with a carburetor engine. He drives his second car with an injection unit. Ready to give a comparative analysis of the two systems. His seven became latest model the classic version, designed for economical fuel consumption, slightly increased dynamics. What actually happened?
Carburetor engine: comparative characteristics
To begin with, it is worth touching on the dynamics of a Zhiguli engine with an injector. What was said in the previous paragraph was not confirmed. Moreover, the problems have only intensified. The injection system did not reduce fuel consumption: such an engine began to accelerate even more slowly than its fellow carburetor. Many owners of such machines sin on the new "brains": the electronics think a little slow, but if you put it in, it should change for the better.
The manufacturer does not agree, he can not do a frisky foal. So far, the carbureted engine is a few steps ahead. You can’t talk about fuel consumption, it doesn’t please even the injection engine 2107 at all. Even the same driving style for a distance of 100 km suggests that it eats half a liter more than the second version of the car.
Injection engine: the second part
There are problems, both with one engine and with the other. The new injector is completely electronic, which means that replacing the ECU with 2107 in the event of a breakdown is possible only on the condition that it will significantly empty your wallet. If you change the entire injection system to the end, then it is better not to do this, but immediately buy a new car.
You can talk about two air flow sensors separately: their replacement will cost 30,000 rubles. For the carburetor, the situation is different: it can be completely replaced with a new one, discarding a third of the above amount. No carburetor either. ideal options. Its repair will be 2-3 thousand rubles less. Is it worth it to boil so much for this money?
Once the work under the hood is done, you can work on the box. Fiat has a larger one, so first you have to change the mounting frame. Blame the long 5th gear. It's okay, collect cardan shaft from 2 parts, where imported elements will stand in front, and native Zhiguli ones in the back.
Vibrations are also easy to pacify: shorten the splines on the front of the cardan by 2 centimeters. After the alteration, they were just at hand.
Now that's all, but if one of you is eager to perform feats, then you can get a blessing in the church or from the leadership of this site.
VAZ-2107: it's time to fill the engine with new oil
According to the rules for Maintenance cars of the 2107 series, you need to flush the entire engine lubrication system after 30,000 km. Drain the old oil, while it is forbidden to unscrew to the end oil filter. Pour into the flushing agent up to the “MIN” mark on your dipstick, start the engine, let it idle for 7-10 minutes. Drain the residue, replace the oil filter. Add motor oil keeping track of its level.
How to change the oil in a VAZ-2107 car engine? The labor process does not represent. Check out the step by step guide:
- Prepare a capacity of 5-6 liters.
- Warm up the engine.
- Install your car on a viewing hole or drive into a flyover.
- Remove the oil filler cap.
- Remove the air filter housing.
- Using a 12 mm (hexagonal) wrench, open the drain plug of the crankcase drain pan
- Drain the oil from the engine into a prepared container.
- Take a puller as an assistant to unscrew the oil filter.
- Use a rag to clean the thread of the plug from the drain hole, wrap it.
- Pour only fresh oil into a brand new oil filter and do not forget to lubricate the rubber gasket located right there with it.
- Screw the filter onto the fitting, after the gasket and the mating ring come into contact, turn the filter 3/4 turn to the right.
- Fill the engine with oil.
- Wait 3 minutes, check its level with a dipstick.
- Install the cover back.
- Run the engine for a couple of minutes, stop it, check the oil level, test for leaks from the gaskets.
Everything worked out? Yes, you are just a professional! Don't want to get to know? You can learn a lot of interesting things if you become a regular visitor to the tuning section. For now, you can only be a student, but remember how children come to first grade and how a small member of society grows up. This also happens to those who service the car.
Wiping away a nostalgic stingy tear, we state that the conveyor life of the VAZ 2107 has successfully ended. Moreover, it ended not at home in Tolyatti, but on a visit, at the Izhevsk Automobile Assembly Plant, where the production of Lada Vesta has been mastered today. The seven was produced for more than 30 years and was even exported to some countries of the world. However, in recent years, the car looked rather modest against the background of new foreign cars, despite the fact that front-wheel drive Ladas reliably covered its rear.
What does an engine replacement
The VAZ 2107 car is essentially a luxury equipment 2105, but all the rear-wheel drive classics are assembled on the basis of the Fiat 124 car and two engines that were assembled under license from the Italian concern. Of course, it cannot be argued that the seven is the same 2101, only with rectangular headlights and a more powerful engine. There is a difference, albeit minor, which clearly do not pull on new model in the factory line.
But since VAZ did not buy other cars, but could not develop its own, the seven can be considered in advance as another model, even according to all the canons automotive world this is far from true. In order not to create illusions, it is enough to look at the development of a single model, say, the Chevrolet Cheville. It was renewed every six months and had a dozen completely different engines and bodies.
Line of engines VAZ 2107
The seven also boasts more than one engine, and depending on which engine can be installed on the VAZ 2107, this was the modification of the car. If we take into account only VAZ engines, then 14 types can be installed. True, they are all the same structurally and repeat the same Fiat 124, but they have different working volumes, different power systems and different attachments. We will briefly try to consider the differences between potential engines for 2107. We do not promise much variety, that is, that is.
The native seven engine is a power unit from a VAZ 2105 car with a volume increased to one and a half liters. On the top five, for the first time in the country, a belt, rather than a chain, camshaft drive was used, which necessitated some changes in the design of the cylinder-piston group and other changes:
The next in the ranking was the engine from 2105 with a volume of 1300 cubic meters with a capacity of 66 forces. Also, at different times, motors from the VAZ 21011 with a timing chain drive were installed on the car, but many consider the triple engine to be the most successful option. The simplest and most correct, correct in terms of the ratio of cylinder diameter to piston stroke, the most verified VAZ engine is the 2103 engine, which was once the engine from the Fiat 125 Special.
We change VAZ to VAZ
But time passed and VAZ got new engines and systems that could be attached to the old engines of the classics. First of all, it concerns the injection system. The injection engine, more precisely, the classic carburetor engine from the seven with an injector was also installed as standard. In addition to the injection system itself, a system of hydraulic compensators, a catalyst and hydraulic system chain tension, if it was a 2103 motor.
However, the not entirely correct application of newer systems brought some inconvenience. Since the organization engine compartment initially did not provide for an injection system, its installation made engine maintenance inconvenient. The catalyst, which reduced ground clearance by a few centimeters. And on our roads, this often led to damage. exhaust system. In addition, drivers are accustomed to self-diagnose and adjust carbureted engines, but with the injector, these things no longer passed. Needed here computer diagnostics which not everyone could and wanted to afford.
The main difficulties in choosing a motor
After finalizing the 2108 engine and turning it into a 16-valve 106-horsepower engine, it became possible to install it on the classic seven. This required some modifications to both the engine shield and the engine mounts. In engines from front-wheel drive VAZ cars, it was necessary to remake the crankcase, since the regular crankcase from the Prior engine could not be installed without the intervention of a welder, the crankcase rested on the front beam. Also required alteration and pipes of the cooling system, starter and partly electrical equipment.
Many have taken the easy route. They simply installed a 1.7-liter 21107 engine from Niva, and both the injection system and hydraulic lifters were already installed on it. The engine was several horses more powerful, the exhaust, thanks to the injection, became cleaner, and the reaction of the engine to the fuel supply was brighter. Of course, Alfa Romeo from the VAZ 2107 will never work, but in the pursuit of perfection, some even installed engines from foreign cars on the seven. Fortunately, this stuff is enough for dismantling, the main thing is to choose a motor that is approximately suitable in size and configuration attachments. diesel engine was not taken into consideration at all, since serious problems could arise with the documents.
But the biggest problem when replacing the 2107 motor with a non-native one was the docking of the transmission with the engine. To do this, it was necessary to integrate the gearbox shaft bearing into the flywheel, since the design of the gearbox in front-wheel drive vehicles did not provide for high loads on the gearbox drive shaft. It is possible that there was some gain when installing another engine on the VAZ 2107, but the problems with passing the technical inspection for many became decisive when looking for the most powerful and modern car.
A slight addition of power to several horses, efficiency and higher dynamics could not cover all the disadvantages of the installation. modern motors on the seven, so for us it will forever remain the same seven, which was the most luxurious mass car in the country of the Soviets.
VAZ 2107 was produced from 1982 until 2012. During this time, he managed to become really people's machine. And no wonder. Cheapness, good reliability of components and assemblies, as well as the ability to repair cars almost “on the knee”. As you know, the "heart" of the car is the motor. And in this article the VAZ 2107 engine will be considered in detail.
What engine can be put on this car
Initially, 2 types of engines were installed on the VAZ 2107 model, these are:
- , with a working volume of 1.5 liters
- VAZ 2106, with a working volume of 1.6 liters
There were also 1.3 liter and 1.2 liter engines, but they are very few in number and almost never occur.
It is also possible to install an engine from a VAZ with a front-wheel drive, but it is too time-consuming and unjustified.
This is interesting!
Sometimes the English letter "i" is added to the name of the car. This means that the VAZ 2107 engine is an injector.Injector - fuel sprayer. Nozzle. According to the principle of operation, injection gasoline engines are very similar to diesel ones.

The main characteristics of the engine are presented in the table below:
| PARAMETERS | MEANING |
|---|---|
| 1972 - our time | |
| Supply system | Injector/carburetor |
| engine's type | inline |
| Number of pistons | 4 |
| Block material | cast iron |
| aluminum | |
| 2 | |
| piston stroke | 80 mm |
| Cylinder diameter | 76 mm |
| Engine capacity | 1452 cm3 |
| Power | 71 l. from. at 5600 rpm |
| Max Torque | 104 NM at 3600 rpm. |
| Compression ratio | 8.5 units |
| Oil volume in crankcase | 3.74 l |
IN this engine AI-93 fuel is used. In practice, motorists can fill in completely different fuels. The most frequent deviations from the norm are the flooding of AI-92 and AI-95. You can read more about this below.
- According to available data, fuel consumption in urban areas is 9.4 liters per 100 km.
- On a flat road at cruising speed, it will already be 6.9 liters per 100 kilometers.
- In mixed mode, the consumption will be from 8 to 9 liters per 100 km. Such figures do not allow us to call this motor economical, but in this case a lot depends on the driver himself.
- Another parameter that depends on the driver is oil consumption per 100 km. For the average driver of a car with this engine, it is 700 grams per 100 km. This, of course, is not small, but with careful driving, this consumption can be reduced up to 450-500 grams / 100 km.
- The weight of the fully assembled 2103 engine is 121 kg.
Its dimensions (the characteristic is indicated in millimeters):
Features of operation and maintenance
- Fuel selection
It was previously said that many drivers cannot decide on the type of fuel used for their engine on the VAZ 2107. And if everything is simple with AI-92, since its composition is very similar to AI-93, then everything is not so with AI-95 smooth.
Increasing the octane number increases the risk of burnt valves, but gives a small increase in power. The engine starts to run smoother and more stable.
But the designers still took into account the possibility of using AI-95 gasoline. You just need to correctly set the ignition timing on your car (if you own a conventional carburetor engine) or reflash the engine control unit (if your VAZ 2107 engine is injection). But usually even this is not required. Engines of this brand are very hardy and not whimsical to the type of fuel (within reason).
- Change of oil
Changing the oil on any engine must be approached with all seriousness. Poor quality oil can lead to not very pleasant consequences, such as accelerated wear of the main components and assemblies.
The ability to select oil is like a real skill. Take famous brands it is not always safe, since you are more likely to come across a fake of dishonest companies. At best, you won't get those positive qualities, which has this company. At worst, it will have to be overhauled.
Unknown brands are also not worth taking. In this case, you are buying a pig in a poke. You can buy oil that is not inferior in quality to expensive analogues, or you can fly into an expensive repair. It is best to take oil in specialized stores, where you can get at least some explanation and compensation.
Also, an important parameter is the class of oil according to the international nomenclature. True, everything is easier here. You just need to take the oil that the manufacturer himself recommends.
The manufacturer (AvtoVAZ) for VAZ 2107 engines and other models with this type of engine recommends:
- 5W-30;
- 5W-40;
- 10W-40;
- 15W-40.
Oil must be taken about 4 liters. When changing 3.5 liters of oil is usually enough. The rest is better to carry with you in the trunk, as the oil consumption in this engine leaves much to be desired.
- Oil change in the VAZ 2107 engine
The procedure itself is quite simple and should not raise questions. It is better to change the oil on the VAZ 2107 in the warm season.
- First you need to start the car and warm it up to operating temperature.
Then shut off and let the oil sink back into the crankcase. This will take about half an hour. During this time, we prepare a receiving container with a volume of 4-5 liters, as well as new oil, a watering can and a hose. - We unscrew the plug on the crankcase with a special key and wait until the old oil flows out.
- If you change the type of oil or brand, you must also take flushing oil, which will clean the motor of the remnants of the old. We pour it out in the same way.
- Then we twist the crankcase cover and fill in new oil through the neck on the cylinder head. We measure the level with a dipstick. It should be somewhere between the MIN and MAX marks. Please note that oil is not water and it cannot quickly sink into the crankcase, and therefore, after a short stop, the oil level in the crankcase will rise a little more.
Usually, along with the oil change, the oil filter is also changed. It's even easier here:
- We unscrew the old one using a special tool (you can also use an ordinary rope), lubricate the sealing ring of the new filter with oil and screw it in place of the old one.
- Adjustment of valves
Adjusting valves is a rather complicated process and requires certain skills and tools. Actually, it is advisable to entrust the valve adjustment itself to competent specialists, but if you want to do everything yourself, then this video is for you:
Overhaul and maintenance
If the valves can be adjusted at home, then the overhaul of the engine should only be entrusted to specialists.
During overhaul all components and assemblies of the VAZ 2107 engine are checked for serviceability. You will be checked for:
- Valve condition, adjustment;
- Chain, chain tension;
- Condition of oil seals, valve stem seals;
- The geometry of the cylinder block;
- piston condition, crankshaft, fingers, connecting rods;
- Wear of compression rings;
- Condition of the oil pump and coolant pump.
In the event of a breakdown, the part will be replaced. The cylinder block is bored out, which will increase the combustion chamber and working volume. After this procedure, several thousand kilometers of the car will be run-in.
Usually, the run-in lasts 5-10 thousand km. At this time, it is not desirable to give the engine heavy loads. After going through this procedure, your engine will please you.
Faults
1. Engine won't start
| Cause of failure | Elimination method |
|---|---|
| No fuel in carburetor | |
| Clogged fuel line | Blow out the fuel line, flush the fuel tank |
| clogged carburetor and fuel pump filters | Rinse filters, replace if necessary |
| Faulty ignition system | Check the ignition system, replace broken parts |
| Does not open air damper carburetor at the first flashes in the cylinders | Eliminate leaks starting device carburetor |
| The carburetor solenoid valve does not open when the ignition is turned on: | |
| break in the wire going to the valve | Check the wire and its connections, replace the damaged wire |
| faulty solenoid valve | Replace valve |
2. The knock of the main bearings of the crankshaft
Usually a dull tone, metallic. Detected upon sudden opening throttle valves at idle. Its frequency increases with an increase in the frequency of rotation of the crankshaft. Excessive axial clearance of the crankshaft causes a sharper knock with uneven intervals, especially noticeable with a smooth increase and decrease in the crankshaft speed.
| Cause of malfunction | Elimination method |
|---|---|
| Too early ignition | Adjust ignition timing |
| Insufficient oil pressure | Check oil pressure |
| Loose flywheel bolts | Tighten the bolts to the recommended torque |
| Increased clearance between necks and main bearing shells | Sand the necks and replace the liners |
| Increased gap between thrust half rings and crankshaft | Replace thrust half rings with new ones or with increased thickness. |
Engine tuning
The most popular types of tuning engines of this type are an increase in working volume, replacement of a camshaft, installation of a filter zero resistance and direct exhaust.
The most efficient way (and most expensive) is to install a turbo kit.
- Increasing the working volume
The device of the VAZ 2103 engine allows you to increase the working volume quite well, since its cylinder block is almost identical to the block of the VAZ 2106 engine. And when boring this block, it can be made under the piston and rings of the VAZ 2106 engine.
Thus, we get an increase in displacement, which increases fuel consumption and power. If even this is not enough, then they grind the pistons from the side of the valves and install the crankshaft from the Niva, which also increases the working volume. Presumably, after these operations, you can get an engine with a working volume of 1.7 liters, sometimes 1.8 liters.
- Installing a new camshaft
This modification does not increase the power of the engine, but changes the nature of its operation. In most cases, they try to install a camshaft that will transfer the maximum torque to the lowest possible speed. This makes the engine more responsive at lower revs, which is very good when driving at low engine revs. The best way for such a modification, this is a camshaft from Niva 21213.
- Installation of direct-flow exhaust and filter of zero resistance
The most popular modification. First, it's pretty cheap. Secondly, it allows the owner of the car to brag to his neighbors in the garages. In fact, it does not bear any practical benefit for the stock engine. Allows you to feel a slight increase in power only at high speeds.
Quite effective when installing Turbo, as it does not crush the engine, which is now capable of developing huge power. The straight-through exhaust is not convenient by increasing the sound of the exhaust. The filter is dangerous to use in wet weather, as it can let water into the engine, causing water hammer.
- Turbo boost installation
The most expensive and effective way to increase engine power, while its resource drops sharply by 2-3, sometimes 4-5 times.
Requires deep exhaust refinement:
- Installing T-Valves
- Imported rings and forged pistons
- Lightweight cranked feces
- intercooler and more.
It is also imperative that your VAZ 2107 engine be injection. The carburetor from such a large pressure can simply break. This article will not describe the procedure for installing Turbo on a VAZ 2107. There is enough such information on the World Wide Web. Here we simply indicate the price of approximately 15% of the value of the car. If you're willing to spend your money on this, go for it.

It is completely identical to the VAZ 2103 engine (see the similar part of the VAZ 2103 engine). The volume of oil in the crankcase is also the same and is 3.75 liters.
Engine tuning
Also identical to the VAZ 2103 engine. See Engine Tuning (VAZ 2103). About the features of boring will be described below.
- Increasing the working volume
It is identical to the paragraph “Increasing the working volume of the VAZ 2103 engine” with the edit that this engine does not require sharpening the cylinder block. It has already been bored out to the desired values.
This article has come to an end. We hope that you were interested and you found answers to the questions: “What engine can I put on my car?”, “How to increase engine power without losing reliability?” and "What is an injector?" As can be seen, despite its modest engine performance, the VAZ 2107 has the potential for modernization and, in terms of speed characteristics, may not be inferior to modern cars.
