The engine power of a car like the VAZ 2114 may seem insufficient for many car enthusiasts. However, this can be fixed. Let's figure out how to convert an 8-valve engine to a 16-valve in a VAZ 2114

If you install a cylinder head with 16 valves, the car's power can exceed all expectations. The reason for this is that the engine cylinders with a similar block head can be filled with a special air-fuel mixture.

As a result, the power of the power unit increases significantly. It is important to note that this is an absolutely safe way to increase the “strength” of your car. So how to convert an 8 valve engine to a 16 valve VAZ 2114?

The question also arises about the difference in power of cars. For example, the power of a car whose engine has a volume of 1.5 liters and 77 horsepower can be significantly improved. If you replace the 8-valve head with a 16-valve one, it will increase to 90 “horses”!

This is quite a big difference, so you should figure out what needs to be done (and in what order) to improve your own car.

Features of engine disassembly

The first thing to do is to disassemble the engine as carefully as possible. This element of the car is the most valuable, so you need to disassemble the engine with extreme caution. It is best to carefully study the instructions and watch videos on the Internet about how craftsmen cope with this task, and only after that do the disassembly yourself.

Under the valve cover you can find many unpleasant defects, including the poor condition of the roller. The cylinder head may also not look its best, and the bushings may be so worn that many are surprised that they still work.

All this means that after the engine is disassembled, a lot of faults or worn parts can be found. It is best to replace each of them. This will increase the reliability of the car and will allow you not to worry that the increased power of the VAZ could become a fatal factor and lead to breakdown in the near future.

It is best to install bronze bushings. They are highly reliable and quite durable.

Specifications and description

The VAZ 2115 has technical characteristics that are quite typical for the 2113-2115 family of models. Thus, the well-known engines of the 2111 and 1118 series were installed on the car. Let’s consider the main characteristics and design of the power unit:

VAZ 2111

VAZ 21114

VAZ 11183

Like the 2114, the 15th model had engines similar in characteristics and design. Of course, the VAZ 2115 engine did not receive the injector 16-valve power unit that car enthusiasts so wanted. Nevertheless, the car still managed to gain popularity and become popular not only in Russia, but also in the CIS countries.

Conversion of an 8 valve engine into a 16 valve VAZ 2114

During the process of improving the engine, it is necessary to modify the bolts. They are used to secure the 16 valve head. To modernize a VAZ engine, there is no need to change the cylinder block, but the head still needs to be changed. In order for each bolt to fit securely into the head mounting hole, it should be adjusted not only in diameter, but also in length.

Important information. The holes that can be found in the gasket also need some work. They should perfectly match the size of the bolts. If this is not done, the level of engine reliability will decrease significantly.

After this you should change:

• first the pistons;

• and then the connecting rods.

Connecting rods VAZ 2114

This must be done while assembling the cylinders.

Now it’s time to refine and adjust the wiring.

It is important to see the difference in the structure of 16 valve pistons from 8 valve pistons. In addition, the location of the sensors also differs. This means that it may be necessary to extend the wiring.

After the engine is assembled, the wiring needs to be finalized. If the car owner would not like to incur extra financial expenses, then he needs to leave the ignition module, and then connect the module using high-voltage wires. This is the easiest way to save money, so don't ignore it.

Cooling

This moment of installation becomes a real problem, because the cooling systems are very different. The algorithm of actions here will be somewhat variable, everything will depend on what you can afford:

If you have the money, you can immediately change the radiator to 2112, but at the same time you will have to fool yourself with modifications to the “TV”, because the new radiator will be much wider. But you can leave the native one, then the problem will arise in the following point:

Although there won’t be any special cooling problems with the original radiator, the radiator from 2112 will more fully cope with cooling the Priorov “heart”.

The bolts may be visually very different from each other, but do not be alarmed. Modified bolts must be used.

Such bolts have the following characteristics:

1. The diameter is equal to an 8 valve bolt;
2. The length is 16 valve.

To make it easier for these bolts to fit into the hole, they should be pre-drilled. If you install the modified bolts according to all the rules and as carefully as possible, then the reliability of the engine can only be envied.

When the car owner thinks that he is not able to perform this operation on his own, then it is better for him to seek help from qualified craftsmen with sufficient experience. They will definitely do everything right and as it should be.

An additional option to increase the power of the car is to tune the exhaust manifold. This is a great way to increase the power of your vehicle a little more.

Engine dismantling/installation

If you have experience installing an engine from a VAZ 2112, then no questions will arise, because the Priora engine on a VAZ 2114 is installed in exactly the same way.

The algorithm of actions is as follows:

If you decide in advance to change the gearbox to a similar one from 2110, then this procedure will not cause problems at all. The only thing is that you need to replace the starter with the 2110, they are slightly different. By the way, you can save money if the starter is KATEK - you only have to change the overrunning clutch and head.

How to increase engine power

To make the correct engine tuning, you need to choose one of several ways to modify the power unit. There are four types of engine modifications that will not cause harm to the latter and will not reduce the life of the engine.

• cylinder boring;
• installation of a new air filter device;
• turbine installation;
• chip tuning or electronic modification of the engine's brains.

You also need to take into account that as the engine power increases, fuel consumption will also increase. Therefore, before you decide to tune your engine, think about whether you need increased fuel consumption.

Increasing the volume of engine chambers

Let's consider the first method of engine tuning - increasing power by increasing the volume of the combustion chamber. To do this, the diameter of the cylinders is bored, and the surface is carefully ground to a mirror finish. The procedure is carried out on a special machine.

They replace regular pistons with forged ones, and the rings with lighter ones. Replace the connecting rods that connect them to the crankshaft.

Experienced mechanics recommend replacing oil injectors if forged pistons are installed. This is necessary for good oil cooling to occur. Since old injectors become unsuitable for further operation.

Installing a new air filter

To properly tune the engine, install an intake filter with reduced aerodynamic resistance. This ensures that air enters the mixer with the least effort. As a result, power increases by four horses.

Attention! In this case, fuel consumption is reduced, which has a beneficial effect on the car owner’s wallet.

Tuning by installing a new air filter is done as follows:

1. Grind the internal intake channels.
2. They install receivers.
3. Change the throttle valve to a new one with a larger diameter.

A direct-flow muffler is installed at the exhaust. All work is carried out in service centers. Under no circumstances should boring channels be carried out in a garage.

Turbocharging installation

Engine power is increased by installing turbocharging. Despite its great efficiency, many car enthusiasts do not dare to take this step due to the high financial costs. Installing a turbocharger requires contacting specialized workshops.

First of all, you need to choose a turbine suitable for the VAZ 2114 engine. There are two types of this device:

• low pressure turbocharger. By installing such a compressor, there is a chance to increase power by 15 percent. However, you will have to tinker with installing such a device;
• high pressure turbocharger. Increases power by 30 percent.

Another point why car enthusiasts do not dare to install turbochargers: the life of the engine is reduced. Since the motor is operated at full power at all times. Wear on parts increases and the engine heats up.

Therefore, you need to install a good engine cooling system. Under no circumstances should you pour water into it, as many car owners like to do. Always use antifreeze to cool power units.

Tuning the gas distribution mechanism

By tuning the gas distribution mechanism, you will not harm the VAZ 2114 engine. In addition, the 8-valve engine will reduce fuel consumption. And the power will be increased.

To tune the engine timing, do the following:

1. Bore the valve seats.
2. The intake and exhaust valves are changed to lightweight ones.
3. The bushings are also changed to light ones.
4. Install the split gear. But it must be configured correctly so as not to subject the engine to major repairs.

Next, let's look at what needs to be done with the split gear to increase the power of the motor.

Split gear method

To make the correct adjustment of the split gear, you need to set the piston to a point called TDC. To lower the speed or bring the speed to an average speed, make the gas-dynamic boost angle smaller and increase the angle of the opening exhaust valve.

To increase speed, the shaft is turned in the opposite direction of rotation of the crankshaft. In this case, the angle of gas-dynamic pressurization becomes larger.

There is another type of increasing the power of a domestically produced power unit. This is chip tuning. Specialists are involved. To improve engine tuning, the electronic engine control unit is reprogrammed. This is done using equipment called a programmer.

Experienced mechanics advise carrying out chip tuning in specialized workshops.
