The VAZ 2112 model began production more than 15 years ago. The car was a fairly successful project in terms of design, since it was due to it that it clearly carried out all the commands given by the driver through the steering wheel. Since then, this car has not ceased to be improved, equipping it with the best components and devices.
The year 2004 became very important for domestic manufacturers, since during this period the car engine was replaced with a more powerful one (124 hp). Its volume also changed – it was now 1.6 liters. At the same time, the height of the crankshaft was changed: it increased by 2.3 mm, which made it possible to improve the running capabilities of the piston by 4 mm.
Features of the VAZ 21124 engine
In addition to the new engine, the car received a slightly different name - VAZ 21124.
Tuning VAZ 21124
What is characteristic is that during the start, the traction at the bottom became more noticeable in it, and the engine operation differs from previous versions in a special calmness (now there is no place for harshness in it).
Often, owners of sixteen-valve units are faced with a problem when the valves in the piston are bent. In the VAZ 21124, the possibility of such a problem is completely excluded: there are special recesses in the piston bottom, as well as sports shafts that control the rise of the piston.
DIY chip tuning
Chip tuning of the VAZ 21124, like other cars, involves flashing the factory engine with camshafts. In order not to harm your “iron horse,” it is preferable to entrust such improvement to professionals, that is, seek help from a specialized center. However, once you understand this procedure, you can tune the car yourself.
Connectors for tuning
The principle of doing chip tuning using Stolnikov 8.9/280 or Nuzhdinov 8.85/273 camshafts with your own hands is as follows: a direct-flow exhaust system (4-2-1 manifold), a receiver and a 54–56 mm damper are installed in the VAZ system. This helps to increase engine power. Replacing the standard piston with a lightweight one from the Lada Priora will also help increase engine efficiency. Thus, changes are made in the system, resulting in a reduction in fuel consumption and an increase in the power of the power unit.
If the power is still not satisfactory after the above manipulations, you can install a wide-phase camshaft and upgrade the cylinder head. In addition, those who like to drive at high speeds can add a compressor and four-throttle starting turbines to the car, which are necessary for stable engine operation and increased sensitivity of the gas pedal.
It works as follows: each cylinder of the engine gets one of the throttle valves, which eliminates resonant air vibrations and, as a result, stable operation of the engine from bottom to top. In this case, attention should be paid to the fact that in addition to such a throttle system, you will need:
- special collector;
- pipe;
- zero resistance filter;
- fuel pressure control;
- absolute pressure sensor;
- System firmware for a four-throttle engine.
After chip tuning of the VAZ 21124 is carried out, the engine power will increase to 180–200 hp.
Advantages of chip tuning
Professional chip tuning of the VAZ 2112 in Moscow from the specialists of the Chipmaster workshop brings benefits:
- improvement of vehicle acceleration dynamics;
- reducing the response time of the gas pedal to pressing;
- increasing the maximum speed of the car;
- eliminating overclocking problems when the air conditioner is running.
If you want to achieve such results at a low price and as quickly as possible, you should order firmware for the VAZ 2112 engine. The price in our workshop is one of the lowest. We provide a long guarantee on all work!

Engine malfunctions and repairs 21124
AvtoVAZ continues to develop 16 valve engines and in 2004 the VAZ 2112 engine was replaced with a 124 engine. It uses a Kalinovsky high block, it is 2.3 mm higher compared to the old block 2112, the piston stroke has increased from 71 mm to 75.6 mm, due to this the volume has become 1.6 liters. On the same block, behind the air filter, above the gearbox casing, there is a platform on which the VAZ engine number 21124 is stamped. By adapting the 124 engine to Euro-3 standards, its environmental performance has increased, low-end traction has appeared, the engine has become quieter and a little noisier than the twelfth . Engine 2110 124 1.6 l. injection in-line 4-cylinder with overhead camshafts, the gas distribution mechanism is belt driven. The service life of the 21124 motor, according to the manufacturer’s data, is 150 thousand km; in practice, the motors run about 200 and even 250 thousand km. This engine solves the problem of 16-valve engines - the VAZ 21124 engine does not bend the valve, for this purpose there are holes on the bottom of the piston and with standard shafts or sports ones with moderate lift, the owner has nothing to fear. Among the disadvantages, it is necessary to tighten the timing belt once every 15 thousand km. If the VAZ 21124 engine is troublesome, there is a knocking or noise, do not be afraid, this is a common situation for AvtoVAZ, read the description of the problems HERE, there is also an answer to the exciting question why the VAZ 21124 engine is overheating According to general reviews, the 124 engine is considered one of the best VAZ engines and is recommended for purchase, especially if serious modifications are planned. In 2007, a new engine was released, replacing the 124th engine - the well-known Priora engine. In addition, based on the 124 engine, the Super-Auto company produced a 1.8 liter VAZ 21128 engine, something is also said about it)
Chip tuning of VAZ 21124 engine: photos and videos
The VAZ 2112 car began production in 1999. The car was a 5-door design with a hatchback body and a convenient design. Thanks to its design, the VAZ 2112 could clearly respond to steering wheel turns. Car production continued, 16-valve engines were improved and developed, and in 2004, designers replaced the car's engine.
The new engine with a capacity of 124 horsepower has changed the height of the crankshaft in the system by 2.3 mm, which is why the piston stroke has increased by 4 mm, and the engine volume is now 1.6 liters.
Engine tuning 21124
There is no point in considering chip tuning of a 124 engine, it will not make any noticeable changes on a standard car, the firmware is needed for more thorough and correct tuning, after the engine has been modified, we will start with it. The simplest and most standard way to increase the power of the 21124 engine is to replace the camshafts with Stolnikov 8.9 280 or Nuzhdin 8.85, install a 4-2-1 direct-flow exhaust, a receiver and a 54-56 mm damper, this will give us a total of more than 120 hp, and for more efficient operation of the motor, we replace the piston with a lightweight Prior one. This will further increase power and reduce fuel consumption. If these numbers are not enough, it is recommended to modify the cylinder head and install wide-phase shafts, which will give an output of 150+ hp.
Compressor for VAZ 21124 16V
As an alternative, and also to obtain similar power over the entire range, you need to install a compressor. The most common compressor for VAZ is the St. Petersburg kit based on the PC-23, but the Internet is full of videos on compressors both on the 8 valve and on the shesnar, in one of the most famous videos, the owner of the motor on the compressor clearly explains all the nuances of installation and what is required for the successful implementation of the project using the example of an eight-valve engine. This compressor can also be installed on a 16 valve engine.
Attention MAT (18+)
It is possible to increase power without using a turbine up to 200+ hp, using a 4-throttle intake, but the most optimal options suitable for urban use are the methods described above.
Fuel supply
Conventional injectors are not enough to operate the engine at high speeds. Since they are constantly in operation, the working pressure in the ramp is simply not enough. In order to increase engine power, you should install the most efficient nozzles, which can increase the volume of sprayed liquid several times. Such changes work most effectively with the 4-2-1 release technology.
Turbocharging
- The most effective, widespread and most expensive type of tuning is the installation of a turbine. After all, it is known that in order to increase engine power, it is necessary to supply the largest amount of a mixture of air and fuel into the cylinders.
- However, to increase the volume of fuel, a mandatory increase in the amount of air will be required, which is what the turbine does. The exhaust gases enter the turbine impeller, then it rotates and drives the compressor, which in turn pumps air into the cylinders.
- Since the air is pumped under pressure, its quantity increases significantly, which leads to an increase in fuel combustion, which results in an increase in power.
- Remember that installing a turbine will lead to a mandatory upgrade of the cooling system (diagram of a standard cooling system here).

Performance Improvement Methods
Increasing the working volume
The best modification of VAZ 2112 engines is this method, it is the most convenient, quite simple, and the most common. It allows you to increase engine torque without changing your driving style. This can be done in two ways - boring the cylinders and increasing the piston stroke, now in more detail:
Increasing the compression ratio
“Compression ratio” is essentially the ratio of the total volume of a cylinder to the total volume of its combustion chamber. By increasing the compression ratio, it is possible to significantly increase the engine power and its efficiency, in addition to slightly reducing gasoline consumption. So:
Chip tuning
Today, perhaps, it is considered the most modern method. It is characterized by relative simplicity and effectiveness. His method is to change the settings of the motor control unit, due to this you can improve some of its characteristics without the risk of repairing this unit afterwards:
Description
The VAZ 21124 engine is part of the line of 16-valve power units produced by AvtoVAZ JSC. It is an in-line 4-cylinder power unit with overhead camshafts and electronic fuel injection (injector).
The gas distribution mechanism is driven by a belt, which must be changed every 45,000 km. At the same time, the manufacturer recommends inspecting it for damage and eliminating sagging every 15 thousand km of the distance traveled.
The VAZ 21124 engine is assembled on the basis of a tall (197.1 mm) cylinder block modification 11193-1002011, the use of which made it possible to increase the piston stroke to 75.6 mm. This led to an increase in the useful volume of the cylinders to 1.6 liters, torque and power of the power unit.
The developers of the 21124 motor managed to eliminate a significant drawback inherent in many motors. If the drive belt breaks, the power unit does not bend the valve. This was achieved by equipping the pistons with special holes that prevent contact between the piston and the valve in an emergency.
The use of hydraulic pushers made it possible to eliminate the need to adjust valve mechanism clearances. True, at the same time, the sensitivity of the engine to the quality of engine oil has increased.

Chip tuning of VAZ 2112 engine
The first thing that comes to the mind of a novice tuner is engine firmware; all companies promise that your engine will at least fly... all this is heresy. Firmwares give the most minimal effect, which is very difficult to feel; you have to think about chip tuning when the engine is with a turbine; aspirated engines are a waste of money. Since it is correct to boost the VAZ 2112 engine, with minimal loss of life and with a maximum increase in horses. The simplest and fairly standard way to increase the power of a VAZ 2112 engine is to replace the camshafts with STI-1 (for a standard receiver), STI-3.1, STI-2 or Stolnikov 8.9 (more expensive than others), to make life easier for the engine, we install a light ShPG from 126 engine, throttle body 54-56 mm, mounted receiver and exhaust 4-2-1. At the output we have about 120 hp. Refinement of the cylinder head and evil wide-phase shafts can increase power to 130-140 or more hp. To this it is worth adding a crankshaft with a stroke of 75.6 to increase the engine capacity of the VAZ 2112 to 1.6 liters, lightweight T-shaped valves, modification of the cylinder head and intake manifold, at the output we get about 140-150 hp. For the city, these indicators are enough for almost any car enthusiast.
Installing a compressor on a VAZ 2112
An alternative method of modifying the 2112 engine and obtaining similar power is to install a compressor. The well-known video clearly explains everything that is required for the successful implementation of the project using an eight-valve engine as an example; this compressor can also be installed on a 16-valve engine, the engine output will be more than 130 hp. You can use other compressors, but blowing more than 0.5 bar into a standard engine without reducing the compression ratio is risky.
Attention MAT (18+)
Throttle for VAZ 2112
To increase the stability of the engine and the response of the gas pedal, install 4 throttles. The bottom line is that each cylinder receives its own throttle valve and, thanks to this, resonant air vibrations between the cylinders disappear. We have more stable engine operation from bottom to top, plus this intake is shorter and air gets into the cylinders as quickly as possible. The most popular method is to install a 4-throttle intake from Toyota Levin on a VAZ. You need to purchase: the unit itself, make an adapter manifold and pipes, in addition to this you need a nulevik filter, injectors, MAP (absolute pressure sensor), fuel pressure regulator and firmware. There are also ready-made 4-throttle intake kits on sale that are quite suitable for use. It is recommended to install a light piston engine (from Priora, for example), because turning a heavy piston is an additional waste of energy, wide-phase shafts, for example STI-6 or STI-7 Touring Light, a modified cylinder head with light valves and solid pushers, Opel C20XE springs, spider exhaust 4-1 or 4-2-1 at 51, and better than a 63 pipe. With the correct configuration, the 2112 engine produces about 180-200 hp. To completely launch the car into space, at a volume of 1.5 liters, we install STI Sport-8 shafts. There is no point in writing a motor configuration for such shafts; very few people decide to assemble such a thing. The disadvantages include a reduction in engine life and this is not surprising, because the engines on the pipes spin at 8000-9000 or more rpm. So you cannot avoid constant breakdowns and frequent repairs of the 2112 engine.

Maintenance
Maintenance of VAZ 21124 engines generally comes down to periodic replacement of consumables - engine oil and coolant.
The main requirement that must be fulfilled is to inspect the engine for leaks. As a rule, replacement of technical fluids is carried out after eliminating detected leaks within the time limits specified in the maintenance regulations:
- engine oil - after 15,000 km;
- The coolant is changed if it has radically changed its original color. Typically, the coolant acquires a rust color after 25-40 thousand km. Before replacing, it is advisable to flush the cooling system.
Malfunctions
VAZ 21124 engines have the same set of characteristic disadvantages characteristic of all VAZ engines. The most common:
| FAULTS | CAUSES | REMEDY METHODS |
| The engine is unstable or stalls at idle. | Ÿ Broken idle speed sensor. |
Air leaks through the crankcase ventilation hoses and the hose connecting the intake manifold and the vacuum brake booster.
If this does not help, check the serviceability of the fuel injection system.
