We increase the power of the VAZ-2112 16 valve engine with our own hands - tuning detected!

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.

Installation of a zero resistance filter

A zero-resistance filter, or simply “zero filter,” is mounted instead of the air filter and its housing. It is designed to reduce the resistance of incoming air into the system. Large filter throughput allows you to increase engine power by a couple of percent. Remember that the correct choice of filter and impregnation for it is the key to proper engine operation.

This tuning is one of the most affordable.

Channels and valves

• The exhaust and inlet channels are supposed to be ground , increasing the diameter at the inlet, and not changing the diameter at the outlet. We remove all irregularities and various joints that can in any way slow down the flow.
• Valves - it is better to use special lightweight or increased diameter ones. It is also expected to use the stiffest or sportiest springs, as well as lightweight valve plates.

Some conclusions

The VAZ 2112 16-valve engine has proven itself to be a reliable and fairly repairable power unit. The most powerful representative is the internal combustion engine VAZ 2112 1.6 liters 16V.

Most car enthusiasts carry out repairs on a sixteen-valve engine with their own hands. Restoring the power unit is quite simple, since it has simple design features.

Currently, the automotive world is developing very well. The fact is that this is the only way to stay afloat and make a good profit from sales. This applies not only to the vehicles themselves, but also to simple units. For example, the VAZ 2112 engine.

In this article we will talk only about this model of the power unit. After all, it has many features that are inherent not only in Soviet times, but also in the present.

The steel receiver looks powerful and beautiful

All VAZ-2112 hatchback engines differ in characteristics, and the differences are significant. It seems that the best option would be a 16-valve 1.5-liter engine. But the 21124 (1.6) engine has its advantages:

• Rated power is achieved at 5000 rpm rather than 5600;
• A broken timing belt does not lead to bending of the valves and their replacement;
• It is acceptable to use 92nd gasoline.

Any 21124 engine can be converted to Euro-4 or meets these standards immediately.

The appearance of the 1.5 liter engine inspires respect. But if you remember about bending the valves, the choice becomes difficult to make. A steel receiver and a beautiful schedule are not everything.

Various nuances

Motor 21124 is more modern than its brother. It has spark plugs with individual coils installed on it. Experienced craftsmen also know about the tuning possibilities specific to the 21120 engine (for example, installing a turbine). In defense of the latter, we can say the following: the service life of the two engines under consideration is approximately the same. After the first 120 thousand, the 20th engine deserves a rating of “4.5 out of 5”.

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)

Ignition system

This component is designed to prepare an air-fuel emulsion and deliver it to the cylinder inlets. It consists of 3 parts: air supply system, gasoline and receiver.

The fuel system includes a fuel rail with injectors, an electric pump, a tank and connecting pipes. The air supply system consists of a paper air filter, hoses and a throttle assembly.

The fuel supply works as follows. Based on a signal from the engine control unit, the pump is turned on and fuel enters the ramp. From it, fuel is injected through nozzles into the receiver, where it is mixed with air. The resulting mixture is drawn into it using the vacuum in the cylinder.

The VAZ 21124 16-valve engine is equipped with an ignition system consisting of NGK BCPR6ES or AU17DVRM spark plugs, a knock sensor and individual ignition coils. The latter are the third innovation in the design of the motor and improve its dynamic characteristics.

Engine control unit and its sensors.

This part is the “brain” of the power unit. It provides all the technical characteristics of the VAZ 21124 engine declared by the manufacturer. The block is designed to coordinate and synchronize the work of all subsystems. It receives information about the current state of the motor using sensors:

• Crankshaft position and speed.
• Mass air flow (MAF).
• Coolant temperature.
• Camshaft positions.
• Detonations.
• Throttle valve positions.
• Double lambda probe, which determines the amount of oxygen in the exhaust gases, installed before and after the converter.
• Rough road sensor.

The described engine is equipped with an ECU 21124 with a BOSCH M 7.9.7 controller, ensuring compliance with Euro 2 and 3 environmental standards.

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).

Specifications

The power unit was installed on VAZ cars: 21104, 21114, 21123, 21124 and 211440-24 (“Super-auto”).

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.

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.

Results

As you can see for yourself, there is nothing complicated about tuning the engine on a VAZ-2112 yourself. However, remember that independent modifications that somehow increase its power have the greatest impact on its gradual wear. Therefore, on a modernized engine, much more attention should be paid to the quality of maintenance, engine oil and fuel used.

Malfunctions

VAZ 21124 engines have the same set of characteristic disadvantages characteristic of all VAZ engines. The most common:

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.
