Body type: SUV
The five-door crossover VAZ 2131 Niva has been produced in small batches at the AVTOVAZ Pilot Plant since 1995. When designing, the designers started from the VAZ-21213 all-terrain vehicle.
The appearance of the engine 21083 is due to the need to increase the power of the serial ICE 2108 of the AvtoVAZ manufacturer. To do this, the designers increased the size of the cylinder, but "forgot" to design the intake manifold for the changed modes.
As a result, cracks in the exhaust manifold open, the bosses are crushed, and the plane of the head is pressed through. Acceleration to 100 km / h occurs in 14 seconds, but the speed is too high for the resulting torque.
Motor Performance 21083
In theory, the technical characteristics of the ICE 2108 should have satisfied the modes of movement of the three-door hatchback VAZ 2108. In practice, tuning was required to increase power, and a little later, a reduction in volume to 1.1 liters for the supply of the Eight for export to countries with special requirements for performance ICE.
Moreover, the model 2108 was designed by the Germans from the Porsche concern for a 5-speed manual transmission, the budget of the AvtoVAZ manufacturer’s plant was not enough for a larger budget, so the internal combustion engine was boosted by domestic designers, the result was a 21083 engine with a volume of 1.5 liters, and then 21081 with a volume of 1.1 liters.
For the latter option, a special inlet manifold was created, as for an export engine. On modification 21083, an intake manifold from 2108 was mounted, which is initially incorrect, since the needs for the quality of the fuel mixture for the formed engine are not met. The same requirements were entered into the manual, which oil to pour, and the regulations for replacing coolants were left the same.
At the output, the characteristics of the engine were as follows:

From the above characteristics, you can see which engine oil is recommended by the manufacturer. Despite design flaws, the 21083 engine has low consumption of gasoline and other operating fluids.
Design features
The main feature of the internal combustion engine, by analogy with the sample 2108, was the use of a belt drive on the timing pulley. In addition, the engine circuit has nuances:
- the camshaft remained inside the cylinder head, that is, on top of the block;
- used non-contact ignition from a distributor, switch and coil;
- to reduce the cost, parts from 2108 are used: crankshaft, flywheel and connecting rods, intake manifold and block;
- pistons created jointly with Kolbenschmitd and Porsche, instead of tin, a micro-profile coating was used to retain lubricant on the surface;
- rings are chrome-plated to increase the resource;
- cylinder head with oversized valves 37 mm.
The modernization also affected the pump of the cooling system, but the resource of this unit increased slightly. As a result, the increased volumes of the combustion chambers added only 6 liters. from. power, but the gear ratios of the gearbox were not selected and the design of the intake manifold was improved. For recognition of the internal combustion engine, AvtoVAZ management decided to paint blocks 21083 blue.
Disadvantages and advantages
The main advantage is that the 21083 engine does not bend the valve when the timing belt breaks. In addition, the engine incorporates design solutions that provide a number of advantages:
- no oil starvation at start-up - a special coating is used to preserve oil on the surface of the pistons;
- free rotation of the finger in the connecting rod bosses - overhaul is less common;
- massive upper head of the connecting rod - the resource of the crankshaft is increased, the overhaul is cheaper;
- refinement of the pump - the cooling system lasts longer.
Despite the fact that the cylinders have a maximum diameter, it is possible to tune the internal combustion engine with your own hands in other ways. The cons are:
- it is impossible to install pulleys of additional attachments on the internal combustion engine shaft;
- torque at high revs is low;
- high thermal loads are dangerous by punching the plane of the head, crushing the bosses and cracking the exhaust manifold.
The second modification of the 21081 motor was more fortunate, since, on the contrary, its volume was reduced, and the development was carried out more carefully for export abroad.
Cars of the VAZ line using the 21083 engine
The 21083 engine was used to complete the following models of the VAZ manufacturer:
- 2108 - three-door hatchback;
- 21083 - three-door hatchback;
- 2109 - five-door hatchback;
- 21093 - five-door hatchback;
- 21099 - sedan;
- 2113 - three-door hatchback;
- 2114 - five-door hatchback;
- 2115 - sedan.
That is, the entire line of front-wheel drive cars produced before 2013 was equipped with these internal combustion engines.
Maintenance
The classic ICE device in combination with the transverse arrangement of the engine under the hood of front-wheel drive cars is subject to the following maintenance regulations:
| maintenance object | Time or mileage (whichever comes first) |

The accompanying instructions contain a description of the parameters, the manufacturer strongly recommends that you follow the maintenance procedure for the 21083 engines.
Malfunctions: causes, elimination
The main problems of this type of internal combustion engine are:
Specifically, the modification of the 21083 motor is characterized by burnt valves that cannot cope with the temperature conditions of the internal combustion engine. This structural flaw is "cured" by tuning existing units.
tuning methods
Several types of tuning are used:
- "chipping" - installation of an electronic analogue of a mechanical regulator, power increases by 15% maximum;
- air filter replacement - low resistance options are used, an exhaust manifold with the same length of pipes and a 52 mm throttle.
Thus, modification 21083 was not the best option for internal combustion engines for VAZ cars. However, a noticeable plus is the safety of the valves in case of a broken timing belt, an improved Ozone carburetor and an increase in power by 6 liters. from.

The VAZ 2108 car is one of the first domestic designs with front-wheel drive. Engineers of the VAZ factories worked on its creation, from time to time resorting to the help of Porsche design consultants.
For the first time, the car went to the masses in 1985, in the back of a hatchback, with three doors. General technical solutions boiled down to equipping this car with a four-cylinder engine with a volume of 1300. It was believed that the power it gave out would be quite sufficient for such a light car. Since then, a lot of time has passed, and the manufacturer AvtoVAZ has not remained standing still. In addition to the standard 1.3 engine, its modifications were born - 1.1 and 1.5. Next, we will learn more about them.
The standard VAZ engine, with a displacement of 1300 cubic meters, can be found on most samples of this model. Its technical characteristics were not at all inferior to the previous Lada models, with an engine capacity of 1500. This was due to the fact that the weight of the 2108 model was much less.
Acceleration to hundreds, the car made in 19 seconds, and the maximum speed was 148 km / h. Engine power is 63 hp, at which fuel consumption per 100 kilometers in the urban cycle was 8.5 liters.
VAZ 2108 with such an engine could be equipped with a four or five-speed gearbox. More often, a 5-speed was used, as it allowed the car to go more smoothly in city traffic, and gave an economical fifth gear when driving on the highway.
After some time, AvtoVAZ released a modification of the previous car, which had the VAZ 21081 index. The difference from the standard engine was that its volume was reduced to 1100. This decision was made due to the fact that Samara 2108 was released for export abroad . And in countries such as Portugal, Belgium, etc., the tax on a car was determined depending on what displacement the engine had. A meeting of domestic design engineers decided to put a shortened crankshaft in the engine, which significantly reduced the piston stroke and reduced its working volume. The cylinder block, in its structure, was completely the same as on the 1300 cc engine. The only difference was that the block itself was located 5.5 mm lower.
The reduction in volume somewhat affected the technical characteristics of the car. For example, acceleration to 100 km / h took as much as 22 seconds, instead of the regular 19, and the maximum speed was 140 km / h. Engine power dropped to 54 hp. But, despite the decrease in all indicators, fuel consumption has not changed - 8.2 liters per 100 kilometers.
Of course, in addition to the export and standard variations of the engine, there was another one developed literally a year after the release of the car from the assembly line - VAZ 21083. It can be safely called the most successful. They worked on its manufacture for quite a long time, since the purpose of the modification was to improve the performance of the car without changing the engine device.
The maximum speed of the improved motor could reach 155 km / h, and acceleration to hundreds in 17 seconds. This gives a significant advantage over the models 2108 and 21081. Power increased by 70 hp, which is 7 hp. more than the stock sample. At the same time, fuel consumption did not increase much, and amounted to 8.6 liters.
Based on this, the question: “what engine to put on the VAZ 2108, for its maximum productivity?”, We can safely answer - the VAZ 21083 engine, with a volume of 1500
Engine device VAZ 2108
Any factory engine of a VAZ 2108 car, no matter what volume it has, has the same design. Before we get acquainted with it, let's figuratively divide the engine into several separate mechanisms:
- Crankshaft;
- Piston group;
- Cylinder head and gas distribution mechanism;
- Parts exposed to high heat and requiring constant lubrication.
Let's start with the crankshaft. Its purpose is to convert the translational movements of the piston into the rotational movement of the wheels. This part is made of cast iron, and has 4 bends (1 for each of the cylinders). There are several holes in the shaft through which oil passes, being cleansed of that dirt and impurities along the way. A flywheel is attached to one end of the crankshaft. It has a significant weight, and serve to maintain rotation, due to its own inertia.
Next comes the piston group. It can be divided into several parts: pistons, rings, pin and knee. All of these parts are exposed to constant high temperatures, so they are made of steel. The exception is pistons. Aluminum is used for their smelting. The piston itself has three rings (2 compression and 1 oil), which prevent exhaust gases from entering the combustion chamber and remove oil from the cylinder walls.
The device of the cylinder head includes the functions of a gas distribution mechanism. This unit ensures that timely fuel injection takes place in the engine, and the exhaust gases leave the cylinder capacity in time. The head is made of cast iron, and the pistons are made of steel.
Additional units
On the VAZ 2108 engine, you can install the Ozone, Solex, Daaz or Weber carburetor. All of them are identical, and apart from the different cross-section of the jets, they do not have any special differences. The factory carburetor on the VAZ 2108 is considered Solex and Daaz, depending on the engine modification.
Also, a fuel pump is installed on the engine, which supplies gasoline from the tank to the car cylinder under high pressure. Along the way, the fuel passes through several filters: a coarse filter, a fine filter, and a mesh filter located inside the carburetor.
Engine maintenance and operation
Repair of the VAZ 2108 engine can take you a lot of money and time. Therefore, in order to avoid breakdowns, you should know how to properly operate the car, and what maintenance should be carried out.
Turn on the ignition, make sure the box is in neutral. It is recommended to start the car with the clutch pedal depressed, as the oil in the gearbox thickens and puts an additional load on a cold engine, which can soon lead to serious damage. Before you start driving, the car needs to be warmed up by raising the number of revolutions per minute to 1500 - 2000.
It is not recommended to fill the VAZ 2108 with leaded gasoline, as it will accelerate the wear of catalytic converters. At least once a week, check the condition of the covers and casings that protect the undercarriage units, since the presence of cracks or holes in them contributes to the penetration of moisture, which will almost instantly disable any unit.
As often as possible, check the condition of the wires, especially the terminals. They must be tightly clamped so that when the ignition is turned on, a spark does not break through them. Otherwise, it may lead to accelerated battery wear.
Engine performance may degrade over time if oil and filters are not changed on time. For example, after every 5,000 kilometers, the driver must install new gasoline filters, as a large amount of water will accumulate in the old ones.
From what kind of oil to fill in the engine, it will be determined how much mileage it can withstand until it is completely worked out. Mineral oil is designed for 3000-3500 km, and semi-synthetic and synthetic - for 5000-7000 km. Before you put any additional unit (supercharging, forward flow, etc.) on the VAZ 2108, make sure that its installation is not prohibited by the car manufacturer. Otherwise, such an improvement can not only reduce the technical characteristics of the engine, but also lead to serious damage to it.

Tuning engine VAZ 21081 1.1 l.
All the improvements of this engine are like a dead poultice, but if your hands itch .. finalize the carburetor, in fact, no matter how it didn’t go, it won’t go. The best tuning replacement of 081 motor with 083 1.5 liter engine.
In the Zhiguli era, the most modest in volume was the 1200 cc engine 2101, which traced its pedigree from Fiat. displacement, and up to 1.2 liters at that time the rate in the Benelux countries (Belgium and the Netherlands) was significantly lower than for cars with engines of larger cubic capacity.
It was in order to increase the attractiveness of cars in the eyes of stingy Europeans that a modification of the VAZ-21081 engine was released. Both stingy burghers and parents of novice motorists liked to buy Lada Samara 1100 - albeit not prestigious, but there are less chances of getting killed at high speed.
Most Samaras with this engine in our country turned out to be the way of re-export. These were dealer modifications of Deutsche Lada (for example, the same Hanseat!), which ran their way around Western Europe, differing from the “bare chisel” in a modified interior and exterior.
