Let's figure out how to convert an 8 valve engine to a 16 valve engine in a VAZ 2114

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.

Why install a new power unit?

Installing a new engine can be useful for those motorists who want to improve their outdated car. Many domestic car enthusiasts know that the “nine” has pretty good driving characteristics, requires little gasoline and is generally not as demanding to maintain as foreign cars, which is why it is often tuned. Replacing an engine from an 8 cl to a more advanced model has its advantages:

1. Increased power.
2. Improved driving characteristics at high speeds.
3. Efficient use of fuel due to the injection system.
4. More stable operation of the power unit.
5. No constant valve adjustment required.

But there are also disadvantages:

1. You need a lot of parts and tools to replace them in your garage.
2. At low speeds the 16 cl engine is slightly worse than its 8 valve counterpart.

There are two replacement options here:

1. Installation of the entire engine from the 2112 model. In this case, not many parts will need to be replaced, but the cost of the entire engine may discourage this idea.
2. Modification of the cylinder head for new components. This is a more economical, but very labor-intensive process.

Installation of a 16 valve head on a VAZ 2114

In order to perform this simple operation, the engine must be disassembled. It is worth warning that many parts will have to be replaced.

These include:

• antifreeze tube;
• oil pump;
• oil sump;
• various sensors;
• crankshaft and much more.

Despite the impressive list, the method described below will really help make the car even more powerful than before.

Cylinder head modification

Installing a 16-valve engine on a VAZ 2109 will be much more difficult if you replace individual parts.

You will need:

• A 16-valve cylinder head with a corresponding receiver (the kit must include a manifold with a knock sensor, a throttle valve and a pressure switch);
• another fuel supply system: gas tank, fuel line, ramp with suitable injectors;
• electronics kit - wiring, controller;
• new sensors for thermostat, oil level, crankshaft position, phases;
• mechanics: thermostat, pulleys for the camshaft, pistons with finished rings and pins, connecting rods, pulley for the crankshaft;
• complete replacement of the exhaust system;
• power supply: generator with suitable tensioners, generator drive;
• other parts: throttle pipes, idle speed regulator, housing for the oil pump with a cast-in mounting location for the crankshaft sensor.

All parts must be suitable in power to work with a 16-valve engine and injection system. The kit is impressive, and there is even more work to complete the VAZ 2109 with 16 valves. Engine conversion begins:

The motor is ready for use.

It’s easier to install a power unit from a VAZ 2112. Of course, you will need a crane to pull out the engine itself, but this is nothing compared to the work that will have to be done to modify the “nine” unit.

Quite a lot of drivers are interested in how difficult it is to install a 16-valve engine on a VAZ 2109. After all, such engines are more efficient than the standard ones installed on the VAZ. This power unit makes you feel much more comfortable on the road. After all, engines with 16 valves are more modern. Such a rework is the most justified and logically sound.

At the same time, it practically does not require complex equipment; there is no need to bore the block and do other things. At the same time, all work is carried out quite quickly and without any interference.

Engine
Installation of a 16 valve engine on a VAZ 2109
can be done in 2 ways. Each has its own pros and cons. Therefore, you can choose one of these methods:

• Installation of the whole unit;
• Replacing the cylinder head.

The final choice depends on your goals and capabilities.
If you have a complete and serviceable engine, you can install it. Otherwise, when buying parts from scratch, it is better to install a new head. To remake your "nine" it is best to use a motor from a VAZ 2112

. They are almost identical. The differences are only in small details. But these nuances are precisely what make this engine more modern. What is important for you is that this engine fits perfectly into the mounts. In this case, you can even use the original box and clutch basket. Next, we will analyze these methods in more detail.

Engine Installation

Let's start with the simplest option - installing a whole motor in the "nine". To do this, in addition to the unit itself, you will need a steel or copper fuel pipe and a gas tank. It is advisable to take the engine with a body kit. So it will cost much less. The installation work is carried out in the following way:

• First, the old motor is dismantled, here everything happens according to the usual scheme;
• We are preparing the new engine for installation. To do this, you need to replace all consumables. Usually they change seals, gaskets, belts;
• The power unit is put in place and attached to the pillows;
• They installed a tank from 2112. It fits perfectly. The difference is in the design of the fuel pump and the presence of sensors. If you don’t have such a tank at hand, you can leave your original one. But you will have to install an external fuel pump from the Volga
  ;
• The next step is to install the fuel line. It is best to use copper tubing. It's more flexible. If you decide to install steel, then heat it on fire before fitting. This will allow you to bend it as needed without any problems;
• Wiring is being installed. On cars younger than 2002, no modifications will have to be made. There is already a hole for the wires coming from the injector, as well as other elements necessary for fastening. If the car is older, you will have to cut the hole yourself. Studs are placed under the bottom for attaching the absorber and gasoline filter;
• The wiring will have to be redone. Some sensors have short wires. In this case, we lengthen them;
• To install the generator you will have to buy new mountings, otherwise you will not be able to install it;
• The box won't fit a little. You need to try it on and grind off the extra corners with a grinder. It's a matter of a couple of minutes;
• The starter installed on 2109 has 11 teeth, it will not converge with the flywheel. Therefore, replace the bendix, take one with 9 teeth;
• The exhaust system will also have to be overhauled and adjusted.

In general, the work of installing such an engine is not too difficult.
In practice, it is not too different from replacing a conventional power unit. Replacing the cylinder head

Compared to replacing an engine, this work is more complex. However, both options have common actions. This applies to installing the tank and connecting the wiring. But there are also enough differences; the work is done as follows:

• First, the engine is removed from the car and disassembled. To do this, remove the cylinder head, pan, dismantle the pistons;
• New pistons from 2112 are installed. They have more reinforced connecting rods, and they also have recesses for the valves;
• Replace the fuel pump;
• Shorten the cylinder head mounting bolts. 12 holes are drilled in the new cylinder head;
• A hole of 8 is drilled in the block and a thread is cut

Tuning is not just about changing the appearance of a car, as many people think. In fact, revisions often concern the technical component. Someone makes changes to the exhaust system, changes elements of the factory engine.

But there is a more drastic, expensive and interesting option - change the engine. With the new engine you get different technical characteristics, increased power, increased maximum speed, better acceleration.

Replacing a motor is a fairly serious step that requires thinking through every stage, from choosing a new motor to the consequences that such work may result in.

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;

Piston VAZ 2114

• 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.

How to convert an 8 valve engine to a 16 valve Installation features

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.

We install the finished engine

We put the 2112 engine on the “nine”, since the power units of the models are similar to each other. You will also need a fuel pipe of a suitable diameter (you can take a steel one, but copper is better) and a gas tank from the same 12th model. The following work is carried out:

1. We dismantle the old power unit, disconnect all pipes and electronics. In order to remove and install the engine, a crane is needed for convenience, since the entire assembly is heavy. This is a major problem in the garage.
2. When the engine is removed, you can install a new one in the seat. It is worth immediately checking the condition of the seals and gaskets if the unit is used. Also check the belt tension.
3. Next you need to replace the entire fuel system: tank, fuel pump, fuel lines.
4. An excellent replacement for the “nine” tank is the analogue from 2112. The parts are the same in size, but their design is different, which is not an obstacle to installation.
5. For fuel lines you need to take copper tubes, which bend better.
6. Now you can start wiring the injector. If the “nine” was produced in 2002 and younger, then there will be no special problems with connecting the wires, but for older models you will have to make new holes manually.
7. You need to install an absorber and a gasoline filter. They are usually placed under the bottom and secured with studs.
8. We install the sensors, change the wiring to one that is suitable in length.
9. Installing the generator will have to work hard, since the original mounts do not fit. Find suitable ones, replace them and you can install them. If the gearbox is not changed, then it will have to be sharpened with a grinder.
10. The starter will have to change the bendix from 12 to 9 teeth.
11. The last modification is the exhaust system. The pipes will not fit, so they will need to be welded. Fitting helps put all the parts in place.
