It's no secret that in its standard, that is, in serial form, the engine does not develop all the power it is capable of. You can configure the firmware in a new way, but you won’t be able to significantly change the load curve without reducing the environmental class. You can buy a "racing camshaft" to install in place of the stock one. But then the firmware will have to be changed to accommodate the new phases... Let's consider what happens if we use only accessible tuning methods. Let's say right away that on the VAZ-2114 hatchback the increase in power can be 20% or even 25%, and we are talking about only 8 valves. There is no need to bore the valve channels.
Let's leave illusions in the past, and for this we watch one video.
An example of increasing the power of a VAZ-2114 engine
During the tuning, the 2111 (1.5 l) engine was modified.
- Boring of seats along the internal diameter, which is equivalent to enlarging the valve;
Valve seats, VAZ 2111 engine
New cylinder head elements
Tuning timing gear
Our new engine remains “not plug-in” - the valves do not reach the pistons. When tested on a bench (the sensors were turned off), the result was not impressive.
Checking without adjusting the ECU
If you install the engineering firmware, you can select the parameters “from start to finish.” And then the picture looks better...

All sensors, including the lambda probe, were connected in the latter case. We managed to get 96 “forces” at 5300 rpm!
How not to increase power!
- Do not attempt to bore channels. This operation can be performed in the absence of ball cutters, but in garage conditions nothing will work even with cutters. The bottom line is that the accuracy of the cutter installation is important - the error should not exceed 1-2 microns.
- As you can see, on the stock VAZ-2114 hatchback the increase in power was 24%, and this is without installing a “chandelier”, “improved exhaust” and other expensive elements.
- There is no point in buying a “racing camshaft” without having the appropriate tuning firmware.
Compressor or turbine for the “six”
You can increase engine power by installing a compressor or turbine, but first you need to figure out what is required for this. First of all, you need to understand that, due to its design features, it is possible to install a turbine on a carburetor engine, but it is quite problematic. The nuances include both large material and time costs. The most important points to think about when equipping a car with a turbine are:
- Mandatory installation of an intercooler. This part is a kind of radiator, only the air is cooled in it. Since the turbine creates high pressure and the air is heated, it must be cooled to obtain the effect of the installation. If you don't use an intercooler, there will be an effect, but much less.
When equipping a car with a turbine, you will also need to install an intercooler. - Equipping a carburetor engine with a turbine is a dangerous undertaking. According to the experience of car owners who carry out such modifications, the exhaust manifold may “bang” and the hood will fly off. Since the intake principle on an injection engine is different, a turbine for this engine is a more preferable option, albeit an expensive one.
- Based on the second point, the third follows - it will be necessary to convert the engine into an injection one or install one.
Installing a turbocharger on a car requires large financial investments.
If you are not such an avid racing driver, then you should look towards the compressor, which has the following differences from the turbine:
- Does not develop high blood pressure.
- There is no need to install an intercooler.
- You can equip a VAZ carburetor engine.
To equip a VAZ 2106 with the unit in question, you will need a compressor kit - a kit that includes everything necessary for converting the engine (pipes, fasteners, supercharger, etc.).
The compressor kit for the “classic” consists of a supercharger and the necessary components for installation
The product is installed according to the manufacturer's instructions.

What to do with engine 11183?
It is clear that a mandatory step in tuning the 11183 engine will be replacing the ECU. It’s simple: the standard M74 block cannot be flashed, but “January 7.2” is a good and time-tested solution. You will also have to abandon the “E-Gas” option, which means replacing the throttle assembly and receiver.
Everything I had to throw away
The intake tract parts were borrowed from the 2111 engine. A cable pedal was installed, and the engine began to look human.
Everything works well with the “January” controller, but standard firmware is not an option if the camshaft has been replaced. And it, in turn, has the following parameters:
- Release phase width – 104 ;
- Intake phase width – 109 ;
- Opening angle at outlet – 272 ;
- Inlet opening angle – 268 ;
- Valve travel (exhaust/intake) – 9.5/10.1 mm.
After installing the new shaft, the motor became plug-in. However, on the 2114 hatchback, increasing power almost always comes with a compromise. In this case, we had to sacrifice reliability. What's improved:
- Maximum torque increased by 14 N*m ;
- The power also increased – the limit of “90 horsepower” was passed.
By the way, any tuning leads to a decrease in durability. Make a choice.
Installation of hydraulic compensators
It will be much easier to purchase an assembled cylinder head with hydraulic compensators for a VAZ-2107. But if you still decide to redo it yourself, then follow these steps:
- All channels through which oil flows must be closed during the work.
- Install hydraulic pusher bushings.
- Press the block head washers.
- Press the O-rings into the hydraulic tappet plate.
- Mount the entire mechanism on the head.
- Install the springs and plungers, then install the valve drive levers 4, 6, 7, 8.
- Check the stroke of the plungers and make adjustments if necessary.
- You need to make a hole in the camshaft pastel and place a tube in it.
- When installing the hydraulic system, ensure that all pipes are directed correctly.
Typically, hydraulic pushers come with detailed instructions that indicate the pipe routing diagram for each engine type.

Method for increasing the power of an 8 valve engine with a split gear
The split, that is, adjustable gear was not used in the last project. It is better to install it on “non-plug-in motors”. Setting method:
- The moving and fixed parts are marked with a mark, the same as on a standard pulley;
- Installation is carried out in the usual manner, aligning the crankshaft and timing mechanism according to the marks (as when replacing a belt), you should also remember about the correct tightening torque of the belt;
- If in the 4th cylinder the intake and exhaust valves are not open “to the maximum”, we carry out an adjustment: loosen the outer screws, and, holding the outer part of the gear, set the camshaft correctly. Tighten the fixing screws.

Filter
Installation of another filter serves to reduce air resistance; alterations are minimal. There are options. The first is to install a new filter in its original place, the second is to install it through an extension cord.
For engines with air injection, there is only the second option, with an air duct extension.
When using a newly installed filter, it is necessary to clean it regularly to ensure consistency of its characteristics.
Tuning parts, popular and not so popular
We have arranged all the elements in order of increasing uselessness:
- Receiver with increased volume. After replacing the standard unit, there is an increase in output at medium and high speeds. But for the region of 1000-2500 rpm, it would be preferable to have a standard receiver.
Receiver with increased volume (shorter path)
Tuning throttle assembly
As for the exhaust tract, you can install a “4-2-1 spider” - it creates a vacuum in front of the valve that is not yet open... Torque and power are improved from this, the question is by how much.
Any “tuning” begins not with the engine, but with the selection of “gear ratios”... This advice is common, and it also applies to the VAZ-2108 and 2114 families.
Working volume
It is possible to increase the engine displacement in several ways. Modernization includes: replacement of the crankshaft; increase in piston diameter. But the above two methods are not very effective.
The most applicable engine tuning is to increase the engine displacement by about 0.1 liters.
A labor-intensive method, but one that gives the best result from the above methods, is to enlarge the cylinder by boring. It is possible to increase the engine volume to 1.8 liters.
Without removing the gearbox
In short, it is quite possible to remove the engine from your “nine” without removing the gearbox. To do this you will have to follow these steps:
- Place bricks or other reliable supports under the gearbox;
- Unscrew the left crab, move the stretcher aside;
- Remove the generator, crankshaft pulley, and camshaft gear from the engine;
- The pump, tensioner pin, distributor, and exhaust pipe are also dismantled;
- If a major overhaul is planned, then you can also remove the head;
- Then the engine mount is removed;
- The motor is moved from the box and lowered to the floor. To remove the engine, the front part is raised higher using a jack and the volume is removed;
- Or you can pull it out through the top using a winch.
In practice, all experts recommend dismantling the engine along with the gearbox. Especially if you plan to replace the engine or increase the power of the standard engine. In this situation, the box itself is often changed so that it can clearly interact with the new motor.
Gearbox from nine
Motor power system
It is possible to make changes to the power supply system of the unit as follows:
- Replace the carburetor with an injection power system.
- Replace the injection engine - install a carburetor.
- Replace the carburetor with an improved model.
The most labor-intensive is the first method of modernization. But other methods also require the purchase of additional components.
Cylinder head
Modernization of the cylinder head is carried out by the following work:
- An absolute match between the collector and the head is achieved.
- The channels are expanded and the internal surfaces are polished.
These works allow you to increase power up to 10%.
What can be changed?
In order to get started, you need to set precise goals. An example would be:
- Increased power. In almost 80% of cases, the engine power is increased, which determines the acceleration time from 0 to 100 km/h. Increased power also causes increased traction in low gears.
- Some are upgrading the engine in order to reduce fuel consumption. Note that fuel consumption can be reduced without significantly changing the engine design - it is enough to restore its condition and configure it correctly.
- You can increase the maximum speed. In some cases, the manufacturer installs a speed limiter that prevents the car from accelerating. An increase in engine size also causes a significant increase in the maximum possible speed.
Sidebar: Important: Changing the engine should also affect other vehicle systems. An example is that fast acceleration can only occur with the correct camber setting, stiff suspension and fairly good brakes. VAZ 2110 engine tuning should be carried out in stages, since mistakes made can ruin the engine.
