Engine for VAZ-2107 can be supplied from both domestic and imported manufacturers.
This type of improvement of the base model is considered tuning, and if it is done with your own hands, then you can earn approval and hear words of admiration not only from drivers, but also from those who have never driven a car. Video confirms this:
Reviews are only positive:
- The boys turned out to be real masters.
- Excellent discs, I liked everything very much.?
- The engine is such that there are no words!
- Great job: the piston is exactly 100 in diameter.
- How cool they connected the box and rear axle. Virtuosos!
- The guys are simply handsome, they managed to do something with their own hands that you don’t mind praising.
- In addition to what has been said, take this advice: if you install the bumper stronger, then the tuning will be a 100% success.
For some future car owners, the question is more serious: which engine to choose? Let's listen to 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 comparative analysis two systems. His seven became the latest model of the classic version, designed for economical fuel consumption and slightly increased dynamics. What actually happened?
Carburetor engine: comparative characteristics
First, it’s worth touching on the dynamics of a Lada with an injector engine. What was said in the previous paragraph was not confirmed. Moreover, the problems have only gotten worse. The injection system did not reduce fuel consumption: this engine began to accelerate even more slowly than its carburetor counterpart. Many owners of such cars are guilty of new “brains”: the electronics are a little slow to understand, but if you install it, it should change for the better.
The manufacturer does not agree; he cannot handle a frisky foal. While carburetor the engine is running a few steps ahead. There is no need to talk about fuel consumption; even the injection engine 2107 is not at all happy with it. Even the same driving style over a distance of 100 km suggests that it consumes half a liter more than the second version of the car.
Injection engine: second part
There are also problems, both with one engine and with the other. The new injector is completely controlled by electronics, which means that replacing the ECU with a 2107 in the event of a breakdown is only possible if it significantly empties your wallet. If you completely change the entire injection system, then it is better not to do this, but to immediately buy a new car.
We can talk about the two air flow sensors separately: replacing them 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. The carburetor also does not have ideal options. Its repair will cost 2-3 thousand rubles less. Is it worth it to get so worked up over this money?
Once the work under the hood is done, you can move on to the box. The Fiat has a larger one, so first you will have to change the mounting frame. The long 5th gear is to blame. No problem: collect cardan shaft of 2 parts, where imported elements will be in front, and native Zhiguli ones in the back.
Vibrations are also easy to tame: shorten the splines on the front part of the cardan by about 2 centimeters. You can leave the rear axle domestic, make a tunnel cut out in the cabin to move the handbrake, otherwise on a Fiat the rocker is located and the shift knobs are a little further away from the driver. After the alteration, they were just at hand.
Now that’s it, but if any of you are eager to accomplish feats, 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 standards provided for Maintenance cars of the 2107 series, you need to flush the entire engine lubrication system after 30,000 km. Drain the old oil, but do not turn it all the way oil filter. Fill in the flushing agent up to the “MIN” mark of your dipstick, start the engine, let it run at Idling minutes 7-10 min. Drain the residue, replace the oil filter. Add engine oil, monitoring its level.
How to change the oil in the engine of a VAZ-2107 car? The process of labor does not represent. Check out the step-by-step instructions:
- Prepare a container of 5-6 liters.
- Warm up the engine.
- Place your car on a viewing hole or drive onto an overpass.
- Remove the oil filler cap.
- Remove the air filter housing.
- Using a 12mm hex wrench, open the crankcase drain pan plug.
- Drain the engine oil into a prepared container.
- Use a puller as an assistant to remove the oil filter.
- Using a rag, clean the plug threads from drain hole, wrap it up.
- Fill a completely new oil filter with only fresh oil 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.
- Replace the cover.
- Start the engine for a couple of minutes, stop it, check the oil level, test for leaks from the gaskets.
Everything worked out? You are simply a professional! Don't want to meet? You can learn a lot of interesting things if you become a regular visitor to the tuning section. You may only be a student for now, but remember what children are like in first grade and how a small member of society grows up. This happens to those who service cars.
VAZ 2107- five-seater a car classic layout with a front longitudinal arrangement of the power unit and rear drive wheels. Engine - four-cylinder, four-stroke, eight-valve, in-line, carburetor or fuel injection. The body is a supporting structure, all-metal, welded. Body type - sedan.
On a VAZ 2107 car it is installed carburetor engine VAZ 2103 model with a working volume of 1.5 liters. The modification of the VAZ 21074 car is distinguished by the engine of the VAZ 2106 model with a displacement of 1.6 liters.
IN last years The production of this model produced modifications of the VAZ 2107-20 car with a VAZ 2104 engine with a displacement of 1.5 liters and VAZ 21074-20 with a VAZ 21067 engine with a displacement of 1.6 liters, equipped with fuel injection, the mechanical part (cylinder block, connecting rod-piston group , crankshaft) of these engines is respectively identical to the VAZ 2103 and VAZ 2106 engines. The VAZ 2104 and VAZ 21067 engines are equipped with more powerful generators and starters with planetary gearboxes. The installation of engines with distributed fuel injection in cars, as well as the use of a gasoline vapor recovery system and catalytic converters in exhaust systems, made it possible to reduce the toxicity of exhaust gases and fuel consumption, and increase the reliability of engine starting in cold weather. Body, chassis and the transmission remained unchanged.

The VAZ 2107 has long become a classic domestic auto industry. However, not all owners know that the model is ideal for tuning and various upgrades. For example, you can significantly optimize the dynamic properties of the “seven” by replacing the motor. The VAZ 2107 easily tolerates all innovations in terms of engine modifications.
What engines is the VAZ 2107 equipped with?
The VAZ 2107 model was produced from 1982 to 2012. Over the 30 years of its existence, the car has been repeatedly refined and changed to more accurately meet modern requirements. Initially, the “Seven” was conceived as a car with rear wheel drive small class sedan. However, in some countries the VAZ 2107 was refined and modified, which is why it can be considered a universal car model.
Depending on the year of manufacture and the country of origin (at different times, the VAZ 2107 was produced not only by the Russian AvtoVAZ, but also by factories in European and Asian countries), the model was equipped with various types musculoskeletal systems:
- LADA-2107 (engine 2103, 1.5 l, 8 cells, carburetor);
- LADA-21072 (engine 2105, 1.3 l, 8 cl., carburetor, timing belt drive);
- LADA-21073 (engine 1.7 l, 8 cells, mono injection - export version for the European market);
- LADA-21074 (engine 2106, 1.6 l, 8 cl., carburetor);
- LADA-21070 (engine 2103, 1.5 l, 8 cl., carburetor);
- LADA-2107–20 (engine 2104, 1.5 l, 8 cells, distributed injection, Euro-2);
- LADA-2107–71 (engine 1.4 l, 66 hp, engine 21034 for A-76 gasoline, version for China);
- LADA-21074–20 (engine 21067–10, 1.6 l, 8 cl., distributed injection, Euro-2);
- LADA-21074–30 (engine 21067–20, 1.6 l, 8 cl., distributed injection, Euro-3);
- (engine 21067, 1.6 l, 53 kW/72.7 hp 8 cells, injector, catalyst) (2007);
- LADA-21077 (engine 2105, 1.3 l, 8 cl., carburetor, timing belt drive - export version for the UK);
- LADA-21078 (engine 2106, 1.6 l, 8 cl., carburetor - export version for the UK);
- LADA-21079 (rotary piston engine 1.3 l, 140 hp, originally created for the needs of the Ministry of Internal Affairs and the KGB);
- LADA-2107 ZNG (engine 21213, 1.7 l, 8 cells, central injection).
That is, in total there were 14 versions in the VAZ 2107 line - either with carburetor engines or with injection ones.
Read about the device injection engines VAZ 2107:
Technical characteristics of VAZ 2107 (carburetor)
The VAZ 2107 was initially equipped with a 1.5 and 1.6 liter carburetor. In the USSR in 1980–1990, almost all produced models were equipped with engines of this size - this power was quite enough for trips around the city and country roads. The engine uses AI-92 gasoline to create the air-fuel mixture. There were also 1.3 and 1.2 liter carburetors, but they were not particularly popular.
The carburetor on the “seven” does not have large dimensions: the device is 18.5 cm wide, 16 cm long, 21.5 cm high. The total weight of the entire assembled mechanism (without fuel) is 2.79 kg. The engine works with spark plugs of a certain type - brand A17DVR or A17DV-10*.
The maximum power was calculated according to GOST 14846: 54.8 kW (or 74.5 horsepower).
The diameter of the working cylinders is 79 mm, while the piston stroke can reach 80 mm. The established order of operation of the cylinders is carried out according to the 1-3-4-2 scheme (every auto mechanic needs to know this scheme, since if the cylinders are not started in an coordinated manner, the operation of the carburetor will be disrupted).
The crankshaft size is 50.795 mm, the shaft itself rotates at a speed of 5400 rpm. When viewed from the front of the car (radiator side), the crankshaft rotates clockwise. The flywheel installed on the model has an outer diameter of 277.5 mm.
Check out the possibilities for tuning the VAZ 2107 carburetor:
The lubrication system on VAZ 2107 carburetors is combined, that is, the rubbing parts are lubricated both under pressure and by splashing. If you follow the recommendations of AvtoVAZ engineers, then you need to fill the carburetor engine of the “Seven” with oils that meet the API SG/CD standard. It is also recommended to select lubricant according SAE classification(Society of Automotive Engineers in the USA). Thus, if you combine these two principles for selecting oils, then it is better to fill the “Seven” carburetor engine with:
- oils produced by Lukoil in the Lux and Super versions;
- Esso brand oils;
- lubricants Shell Helix Super;
- Norsi Extra oils.
AvtoVAZ has established acceptable oil consumption during vehicle operation. Thus, a loss of 0.7 liters of oil per 1000 kilometers is considered acceptable (of course, if there are no leaks).
Where does this rate of 700g per 1000 come from??? This is more like the GAZ-53 norm, at least in the farm where I worked at one time they gave a liter of oil for about 200 liters of gasoline. I wrote purely on my own occasion - I always kept MAX oil. in the crankcase, and did not leak or drip from anywhere, and when replacing the level was 2 matches below MAX. there was, and it was over 8000. This is normal oil consumption, as in the book “natural oil consumption for waste.” And when did it become when replacing MIN. I put it on capital, and, as it turned out, it was not in vain

Carburetor engine life up to overhaul relatively small - approximately 150–200 thousand kilometers. However, due to the simplicity of the design, major repairs will not be required large investments, while the updated motor will operate in the same mode as the new one. In general, the service life of the VAZ 2107 engine greatly depends on the driver’s driving style and care:
It depends on how you drive and what kind of oil you use. Ideally - 200 thousand, then capital is guaranteed
Enlightened
I used 270 thousand, I would have used more, but an accident forced me to disassemble it and replace everything that was needed without boring.

Where is the engine number
Each model vehicle, produced at the factory, is equipped with a motor with a personal number. So, the engine number on the “seven” is its identification number, which can be used to determine the identity of the stolen car and its history.
The engine number is stamped on the cylinder block on the left side, immediately below the distributor. In addition, the number is duplicated in the summary table, which is attached below the air supply housing. The metal plate contains information about the car, such as model, body number, model and number of the engine unit, equipment, etc.
What engine can be installed on a VAZ 2107 instead of the standard one?
Some car enthusiasts who are accustomed to upgrading cars with their own hands decide to replace installed motor to a more productive one. Like any other car, the “Seven” can be converted and equipped with an engine from another car, but a number of rules must be followed:
- The replacement engine must exactly match the dimensions and weight of the standard device. Otherwise, there may be problems with the operation of the new motor.
- The new engine must be mated to the existing transmission.
- The power of the new power unit cannot be greatly overestimated (no more than 150 hp).
Motors from other VAZ models
Of course, first of all, the owners of the “Seven” turn their attention to the engines of other VAZ models. The best option(slightly more powerful and more durable) - this is a carburetor from a VAZ 2114. It fully matches the dimensions of the VAZ 2107 carburetor, but is a more modern and productive device. In addition, you can install the engine with a VAZ 2114 practically without any modifications - the only problems may arise with the RPD, but they are easily solved.
Motors from earlier VAZ models (2104, 2106) are also quite suitable in their dimensions and weight to replace the VAZ 2107 motor, however, replacement will not be advisable, since outdated devices will not give the car dynamics and durability.
Engines from foreign cars
The VAZ 2107 can also be equipped with an engine from an imported car. Ideal for replacement power units from the Fiat and Nissan brands. The thing is that the progenitor of VAZ engines were Fiat engines, which also served as the basis for the development of Nissan engines.
Therefore, engines from these foreign cars can be installed on the “Seven” without any alterations or modifications.
Rotary engine
There was a period in the history of AvtoVAZ when some car models (including the “seven”) were equipped rotary piston engines. Initially, such installations were highly productive, but the VAZ 2107 with such engines had many disadvantages:
Today, rotary motors are installed only on Mazda models, so if you wish, you can purchase such a power unit at a showroom or in official Mazda stores
A new rotary engine can be installed on the VAZ 2107, but the design of the car itself will not allow for maximum optimization of all the capabilities of the car. Therefore, rotary engines are not popular among VAZ 2107 owners.
Diesel engines
Car enthusiasts, in order to save on fuel, sometimes replace gasoline power units with diesel ones. On a VAZ 2107 you can also carry out this procedure. Again, for replacement it is better to take engines from Fiat and Nissan. Diesel engines more economical than gasoline, but require increased attention from a car enthusiast, as they are very capricious in terms of maintenance.
The undoubted advantage of diesel is lower fuel consumption. I really don’t know how much VAZ diesel consumes. But our price for Euro diesel fuel is almost equal to 92 gasoline. Namely, one dollar per liter without a few kopecks…. like this

Thus, the VAZ 2107 carburetor was initially designed for typical loads and a short service life before the need for repair. However, the repair itself is considered a simpler and more accessible procedure than, for example, the overhaul of an injection engine. In addition, the nuances of the “Seven” design give owners a chance to install engines from other car models in order to get the quality of work that is required.
VAZ 2107 was produced from 1982 until 2012. During this time he managed to become truly people's car. And no wonder. Cheapness, good reliability of components and assemblies, as well as the ability to repair a car almost “on the knee”. As you know, the “heart” of a car is the engine. And in this article the VAZ 2107 engine will be discussed in detail.
What engine can be installed 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 L and 1.2 L engines, but they are very few in number and practically never found.
It is also possible to install an engine from a VAZ with front-wheel drive, but it is too labor-intensive and unjustified.
This is interesting!
Sometimes the English letter “i” is added before 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 very similar to diesel ones.

IN this engine AI-93 fuel is used. In practice, motorists can fill in completely different fuels. The most common 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 conditions is 9.4 liters per 100 km.
- By smooth road at cruising speed it will already be 6.9 liters per 100 km.
- In mixed mode, consumption will be from 8 to 9 liters per 100 km. Such figures do not allow us to call this engine 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 g per 100 km. This, of course, is not small, but with careful driving you can reduce this consumption down to 450-500 g/100 km.
- The weight of the 2103 engine when fully assembled is 121 kg.
Its dimensions (characteristics are indicated in millimeters):
Features of operation and maintenance
- Fuel selection
It was said earlier that many drivers cannot decide on the type of fuel used for their engine on the VAZ 2107. And if with AI-92 everything is simple, since its composition is very similar to AI-93, then with AI-95 everything is not so smooth.
Increasing the octane number leads to an increased risk of valve burnout, but gives a small increase in power. The engine begins 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 have a conventional carburetor engine) or reflash the engine control unit (if your VAZ 2107 engine is fuel-injected). But usually even this is not required. Engines of this brand are very durable and not picky about the type of fuel (within reasonable measures).
- Change of oil
Changing the oil on any engine must be approached with the utmost seriousness. Poor quality oil can lead to not very pleasant consequences, such as accelerated wear of main components and assemblies.
The ability to select oil is a real skill. Taking well-known brands is not always safe, since you are very likely to come across a counterfeit from dishonest companies. At best, you will not receive the positive qualities that this company has. At worst, you will have to carry out major repairs.
You shouldn't buy unknown brands either. In this case, you are buying a pig in a poke. You can buy oil that is of a quality that is not inferior to expensive analogues, or you can end up with expensive repairs. It is best to buy oil in specialized stores, where you can get at least some explanation and compensation.
Another important parameter is the oil class according to the international nomenclature. True, everything is simpler 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.
You need to take about 4 liters of oil. When changing 3.5 liters of oil is usually enough. It’s better to carry the rest with you in the trunk, since oil consumption in this engine leaves much to be desired.
- Changing the oil in the VAZ 2107 engine
The procedure itself is quite simple and should not raise any questions. It is better to change the oil on a VAZ 2107 in the warm season.
- First you need to start the car and warm it up to operating temperature.
Then turn it off and let the oil fall 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. - Use a special wrench to unscrew the plug on the crankcase and wait for the old oil to drain out.
- If you change the type of oil or brand, you must also take flushing oil, which will clean the motor from the remnants of the old one. We pour it in the same way.
- Then we tighten 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 changing the oil, the oil filter is also changed. It's even simpler here:
- We unscrew the old one using a special tool (you can also use an ordinary rope), lubricate the o-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:
Major repairs and maintenance
If valve adjustment can be done at home, then major engine repairs should only be entrusted to specialists.
During a major overhaul, all components and assemblies of the VAZ 2107 engine are checked for serviceability. They will check for you:
- Valve condition, adjustment;
- Chain, chain tension;
- Condition of oil seals, valve stem seals;
- Geometry of the cylinder block;
- Condition of the pistons, crankshaft, pins, connecting rods;
- Wear of compression rings;
- Condition of the oil pump and coolant pump.
If damaged, the part will be replaced. The cylinder block will be bored out, which will increase the combustion chamber and working volume. After this procedure, the car will be run-in for several thousand kilometers.
Typically, running-in lasts 5-10 thousand km. At this time, it is not advisable to give the engine heavy loads. After completing this procedure, your engine will make you happy.
Malfunctions
1. Engine won't start
| Cause of failure | Elimination method |
|---|---|
| No fuel in carburetor | |
| Fuel line clogged | Blow out the fuel line, flush the fuel tank |
| Carburetor and fuel pump filters are clogged | Wash filters and replace if necessary |
| Ignition system is faulty | Check the ignition system, replace broken parts |
| The carburetor air damper does not open at the first flashes in the cylinders | Eliminate leaks in the carburetor starting device |
| 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 |
| solenoid valve faulty | Replace valve |
2. Knocking noise from the crankshaft main bearings
Usually the knock is dull, metallic. Detected upon sudden opening throttle valves at idle speed. Its frequency increases with increasing crankshaft speed. Excessive axial clearance of the crankshaft causes a sharper knock with uneven intervals, especially noticeable with a gradual increase and decrease in the crankshaft speed.
| Cause of malfunction | Elimination method |
|---|---|
| Ignition too early | Adjust the ignition timing |
| Insufficient oil pressure | Check oil pressure |
| Flywheel mounting bolts are loose | Tighten the bolts to the recommended torque |
| Increased clearance between journals and main bearing shells | Sand the journals and replace the bearings |
| Increased clearance between thrust bearings half rings and crankshaft | Replace thrust half-rings with new ones or thicker ones |
Engine tuning
The most popular types of engine tuning of this type is to increase the working volume, replace camshaft, installation of a zero-resistance filter and direct-flow exhaust.
The most effective way (and the most expensive) is to install a turbo kit.
- Increase in working volume
The design of the VAZ 2103 engine allows for a good increase in displacement, since its cylinder block is almost identical to the VAZ 2106 engine block. And when this block is bored, it can be made to fit 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 sharpen the pistons on the valve side and install a crankshaft from the Niva, which also increases the working volume. Presumably after these operations you can get an engine with a displacement of 1.7 liters, sometimes 1.8 liters.
- Installing a new camshaft
This modification does not increase engine power, but changes the nature of its operation. In most cases, they try to install a camshaft that will transfer maximum torque to as low a speed as possible. This makes the engine more responsive at lower speeds, which has a very good effect when driving at low engine speeds. The best option for this modification this is a camshaft from Niva 21213.
- Installation of direct-flow exhaust and zero-resistance filter
The most popular modification. First of all, it's pretty cheap. Secondly, it allows the car owner to show off to neighbors in the garages. In fact, it does not have any practical benefit for the stock engine. Allows you to feel a slight increase in power only at high speeds.
It is quite effective when installing Turbo, since it does not put pressure on the engine, which is now capable of developing enormous power. Direct-flow exhaust is not convenient due to increased exhaust sound. It is dangerous to use the filter in wet weather, as it can let water into the engine, causing water hammer.
- Installation of turbocharging
The most expensive and effective method increase engine power, while its resource sharply drops by 2-3, sometimes 4-5 times.
Requires deep exhaust tuning:
- Installing T-Valves
- Imported rings and forged pistons
- Lightened crank feces
- Intercooler and much more.
It is also necessary that your VAZ 2107 engine be fuel-injected. The carburetor can simply burst due to such high pressure. 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 will simply indicate a price of approximately 15% of the cost of the car. If you are ready to spend your money on this, go for it.

Dimensions and Weight are identical (see paragraph Characteristics of the VAZ 2103 engine).
Features of operation
Completely identical to the VAZ 2103 engine (see similar VAZ 2103 engine design). The oil volume in the crankcase is also the same and is 3.75 liters.
Engine tuning
Also identical to the VAZ 2103 engine. See the section Engine tuning (VAZ 2103). The features of boring will be described below.
- Increase in working volume
Identical to the point “Increasing the displacement of the VAZ 2103 engine” with the exception that this engine does not require sharpening the cylinder block. It has already been bored to the required values.
This concludes the article. We hope that you were interested and found answers to the questions: “What engine can be installed in my car?”, “How to increase engine power without losing reliability?” and “What is an injector?” As you can see, despite its modest engine performance, the VAZ 2107 has the potential for modernization and speed characteristics may not be inferior to modern cars.
