Engines 21083 and 2111 of VAZ 2108, 2109, 21099

One of the most famous developments of Soviet motor vehicles is the VAZ 2109 engine and its various modifications. Thus, the motor, which was developed back in 1982, serves faithfully to this day. This is one of the most common engines in the CIS.

It must be said that this is not considered one of the reliable units, but it is very repairable, which makes it quite popular among car enthusiasts.

Description and modifications

As such, a “nine” engine does not exist in nature. At least, the AvtoVAZ plant did not produce it. All 2109 models were equipped with a figure-eight power unit and its modifications. Of course, in many documents you can find the VAZ 2109 engine, but this is deception or ignorance.

But in the technical documentation of the manufacturer you cannot find information about the 2109 engine, since such an engine does not exist. Over the entire period of their production, all “nines” were equipped with engines with the following markings: VAZ-21081 (1.1 8V), VAZ-2108 (1.3 8V), VAZ-21083 (1.5 8V), VAZ- 2111-80 (1.5i 8V) and VAZ-11183-20 ​​(1.6i 8V).

What influences the replacement

There are two main factors that force motorists to replace airbags.

1. Natural wear and tear. Each pillow has its own service life, exceeding which is very rare. Often they don’t work it out for the second reason.
2. Mechanical impacts leading to breakdowns. These are our roads, potholes, accidents, collisions with manholes, etc.

When replacement is required

There are several factors you should know about replacing engine components.

We recommend: High-quality batteries for cars and motorcycles

If you do not replace the supports in a timely manner, this will lead to more serious consequences and expensive repair of the breakdown. Therefore, it is better to replace the pillows when primary signs of wear are detected. To do this, we additionally recommend periodic inspection of the unit.

Specifications

All engines that were installed on the VAZ 2109 were small in volume, but had sufficient power characteristics and dynamics. But things didn’t work out with the traction power. The engine power of the VAZ 2109 ranges from 54 to 81 horsepower. It is worth considering each engine option and its technical characteristics separately.

21081 (1.1 8V)

2108 (1.3 8V)

21083 (1.5 8V)

2111-80 (1.5i 8V)

11183-20 ​​(1.6i 8V)

As you can see, the evolution of engines has come from the carburetor type to the injection type. Although with an increase in engine volume, fuel consumption also increased proportionally.

Another important fact remains the question: where is the engine number on old models of engines? As you know, the engine number was stamped on the cylinder block only from 1984 and on earlier versions that were exported. Therefore, you shouldn’t even look for this identifier on a 1983 power unit, since it simply doesn’t exist.

Exhaust system

Studies have shown that a car loses a significant part of its power precisely due to the exhaust gases leaving the system. Accordingly, if you modify the exhaust system, you can significantly increase engine power. This method is good because it does not require an experienced mechanic's hand. There is also no need to modify the motor itself. Engine

remains in the same state. But in order for gases to be released at a greater speed, you need to carefully calculate the design of the exhaust system of your car. The whole point of the modification is to increase the diameter of the pipes, change their profile and internal polishing. The method is less complicated than the previous two, but also very labor-intensive.

What can this do? Thanks to modifications to the exhaust system, engine power increases by 15 percent. I'm going to change my winter tires soon. What tire size is suitable for the VAZ-2114 (except 17570 R13)?. If you consider that during the work you never disassembled the engine, but simply “tuned” the pipes, then this method can be considered one of the most effective among all others.

Repair and service

On average, repairs to internal combustion engines of VAZ 2109 modifications are done based on mileage. This figure is about 200,000 km. Engine overhauls are carried out similarly to any Zhiguli power unit. Since, compared to the Volgovsky engine, the Vazovsky is quite small, motorists often do the bulkhead in their garage with their own hands.

The 2109 engine is highly repairable, since the cast iron block is quite difficult to destroy, and the cost of the head is low, which allows you to repair the internal combustion engine cheaply and without much expense with your own hands. Another positive factor in the repair is that the power unit is simple in design and even inexperienced car enthusiasts are able to carry out minor repairs to the VAZ 2109 engine with their own hands.

The main problems that many people face include: changing the oil in the VAZ 2109 engine, replacing spark plugs and high-voltage wires, as well as overhauling and adjusting the carburetor. By the way, almost all engines were equipped with an excellent injection element, which everyone knows as “Solex”.

Another question that car enthusiasts often ask is how much oil should be poured into the engine? This indicator depends on the type of motor. For example, for a VAZ-21081 this will be one indicator, but for a VAZ −11183-20 ​​it will be completely different. Therefore, if a motorist wants to know how much oil is in his power unit, he needs to look at the technical documentation.

Which option is best?

As you can see, there are a lot of ways to modify the “nine” engine. We recommend simply replacing the motor with another one. But not from a foreign car, but from an injection VAZ. Fuel pump for VAZ 2108 2109 21099 fuel pump injector VAZ 2108 2109 21099 1) and video. This way you won’t have problems with installation (after all, the body design has not changed for decades) and queues at the traffic police. As a last resort, you can make the engine in the PTS numberless.

Well, in addition to the new engine, you can modify the old exhaust system, replace the manifold and muffler. By performing all these operations, you will increase the power of your car by 30-40 percent. What thermostat should I put on the 402 engine? Engine. After such tuning, the car will “take a hundred” in 10 or even less seconds. The main thing is to know the sequence of all tuning work.

Tuning

Tuning the VAZ 2109 engine is quite simple and without any particular difficulties. So, the first thing motorists do to their engine is change the ignition system. Of course, on older models there is a contact version installed, which has long been obsolete, and therefore contactless is installed.

At the same time, spark plugs and high-voltage wires are changed. Don't forget about the ignition coil either. All this will give improved fuel combustion in the cylinders only if everything is configured correctly.

Next comes boring and reassembly of the cylinder block. So, many car enthusiasts install a sports piston version, which provides a lightweight crankshaft, pistons and connecting rods. Then, the guide bushings and valves are changed. All these modifications will give an increase in power by about 25-30 horses.

The last stage is external tuning. This may include: installing a zero-resistance air filter, overhauling the carburetor, replacing water cooling pipes, installing an improved pump and generator.

Do not forget about such an important element as the starter, a range of varieties that can be found in tuning stores. It is also recommended to replace the radiator with a lighter one, that is, install an aluminum one. All this will give more opportunities for the engine, and accordingly for the motorist.

Installation of a 16 valve engine on a VAZ 2109. More power my lord

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

• 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.

• 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 for the knock sensor;
• They install a pump from 2112, at the same time install a thermostat from “Samara”;
• Change the breather;
• All that remains is to assemble the entire body kit for the engine, install the wiring and configure the unit.

Conclusion

The VAZ 2109 engine, or rather its varieties that were installed on the car, became legends of the Soviet automobile industry. So, having a fairly small size, it was powerful, which gave it great popularity among motorists. Another positive factor was that repairing the VAZ 2109 engine is quite easy to do with your own hands, which allows any car enthusiast to reduce costs at a car service center.

With the popularization of tuning, most drivers who owned 2109 engines began to carry out modifications and, as practice shows, quite successfully.

Replacement

Now we move on to replacing elements. Doing it yourself or contacting a car service is purely your personal decision.

For the VAZ 2109, the use of three supports is provided:

• Front;
• Rear;
• Left side.

The replacement of each of them should be discussed separately, since the processes differ from each other.

Replacing the rear cushion

1. Find a suitable place to carry out repairs. You will need a pit or overpass.
2. Place the car there, secure it with stops, and put the car on the handbrake.
3. Disconnect the negative terminal from the car battery.
4. Using a 17mm spanner, unscrew the nut that holds the cushion to the body.
5. Using a 17 socket, remove the mounting nuts of the support bracket to the gearbox. There are 3 of them in total.
6. Remove all the bolts and remove the old engine mount.
7. Install a new motor element and reassemble the unit.

Dismantling works

1. Provide yourself with free access to the bottom of your VAZ 2109.
2. Secure the vehicle with jack stands and the handbrake.
3. Disconnect the minus from the battery.
4. Remove the left engine splash guard.
5. Using a 17mm spanner, remove the nut that holds the cushion to the body.
6. Using a 17 socket, unscrew the 3 mounting nuts of the support bracket, removing them from the gearbox.
7. After removing the mounting bolts, replace the worn engine mount with a new one.
8. Carry out the reassembly procedure. Stick to strict consistency.

Replacing the front airbag

Here, follow all the same conditions that were relevant for previous works. That is, drive the car into a pit, place supports and turn off the power to the car by removing the negative terminal from the battery.

1. Using a 17mm spanner, remove the nut holding the cushion to the body.
2. Using a 17mm wrench, remove the 4 fastening nuts securing the airbag to the engine.
3. Remove the rubber element from the eyelet.
4. Place a new support in place of the old unit.
5. Reassemble the unit.

When replacing engine mounts, be sure to make sure that the new mounts meet the quality and size requirements. It is also recommended to thoroughly clean the seats before installing a new element, which will extend the service life of the new motor mounts.

Replacement does not require special skills, special tools or special conditions. Therefore, VAZ 2109 owners often change the pillows with their own hands. But if you are not confident in your abilities, contact a trusted car service center.
