Tuning the VAZ “classic” engine: how to increase power

Increasing the power and engine capacity of the VAZ 2114

The VAZ 2114 engine size and its characteristics changed and improved throughout the entire production period, from 2001 to December 2013.
The first batch of VAZ 2114 cars were equipped with 1.5 liter 8-valve injection units. After the modernization in 2007, new engines with a volume of 1.6 liters were installed on the “fourteenths”. New production VAZ-11183-1000260 engines received environmental class 3, Euro-3. The most powerful of all VAZ units was assembled and installed on the Lada Priora in 2010. The power of this power plant was 98 horsepower. A common feature of all engines of the VAZ 2114 model is that they are 4-stroke and have the same distributed fuel injection system. Fuel is supplied to the engine cylinders thanks to installed injectors. Today, this method of powering engines is the most efficient of all fuel supply schemes. The engines have a standard, in-line appearance, and their camshaft is located on top. A closed liquid system is used to cool the units. Some mechanisms are lubricated with oil under pressure, others by spraying oil.

Characteristics of VAZ 2114 engines

A very common engine model on the VAZ 2114 was an engine with a total power of 81.6 hp. With. with serial number VAZ 21114. This is an in-line type of power plant that uses an injection power system. The cylinder block is made of cast iron. The rotation speed of the power unit reaches 5200 rpm. For high-quality operation, the engine is filled with AI-95 gasoline.

Unlike its predecessor (VAZ 2111), in the updated VAZ 21114, due to the installation of an improved crank and an increase in the stroke of the piston system, the engine volume increased by 0.1 liters. The total volume of the VAZ 21114 engine was 1.6 liters. In addition, it has become much more powerful. The downside to the increase in volume was a decrease in torque.

The piston stroke of such an engine on a VAZ 2114 reaches 71 mm. The cylinder diameter size is 82 mm. Engine displacement varies from 1499 to 2114 cm³. Torque - 116 Nm/3000 rpm. Fuel consumption in the city reaches 8.8 liters, on the highway it is significantly lower - 5.7 liters per 100 km. Oil consumption - 50 g/1000 km. Engine weight 2114 - 127 kg.

According to factory data, the resource of the unit is 150 thousand km, in fact – up to 250 thousand km. Definitely, the VAZ 2114 will not suit adrenaline junkies and fans of racing on the highway. This option is perfect for business, self-confident people. The car will cope perfectly with the need to transport heavy trailers and so on.

If you want to have a faster option, it is better to opt for the one and a half liter VAZ 2111 engine. The reduced stroke of the piston system allows the engine to gain speed faster.

Selecting the number of engine valves

The selection of an engine largely depends on the number of valves installed. Early VAZ 2114 models were distinguished by engines with 8 valves. After 2007, eight-valve engines were replaced by engines with 16-valve heads. Valves in internal combustion engines are used to admit the air-fuel mixture and exhaust exhaust gases. Accordingly, the higher the valve capacity, the stronger and more powerful the motor.

It is easy to conclude that the gas throughput through a head with 8 valves is much lower than through a 16-valve head. Although 8-valve engines perform poorly at high revs, they produce excellent low-end torque.

An engine with 16 valves can pass more gases through itself, due to which the car accelerates faster. Unfortunately, this design also has disadvantages, the main one of which is the deformation of the valves themselves. 16-valve engines have not yet stood the test of time, so eight-valve engines are still considered more reliable.

When choosing an engine for a VAZ 2114, you must be guided by the following principles. A 16-valve engine (1.6 L) or an 8-valve engine (1.5 L) is chosen if high speed and high torque are required. With an emphasis on stable and powerful low-end thrust, the 1.6L 8-valve engine is the best option.

Causes and repair of motor malfunctions

As already mentioned, according to AvtoVAZ, the maximum service life of the VAZ 2114 engine is 150 thousand km. With normal and timely maintenance, the engine can work longer. The standard operating temperature range is from 95 to 103 °C. An oil change should take place on a warm VAZ 2114 engine every 10-15 thousand km. When the first signals about a car malfunction appear, you must contact the station or find the cause yourself. The most common engine problems.

1. Floating engine speed. As a rule, this happens in new cars and at idle speed. If the car has no mileage, go for diagnostics; repairs should be carried out under warranty. The cause of the problem may be the idle speed control, throttle position sensor or vacuum unit.
2. The car engine stalls while driving (floating engine speed plus problems with the mass air flow sensor) - the causes of the breakdown are the same.
3. Uneven engine operation (troit). Cylinder compression measurements should be taken. If one of them has low compression, then the valve or head there has burned out. If the difference in measurements is small, then the pressure in the valves should be adjusted or the gasket replaced. If compression measurements do not show any deviations, then you need to check the ignition module.
4. The engine does not reach normal operating temperature. The reason lies in a faulty thermostat.
5. Noises and knocking noises in the engine. As a rule, the cause is poor valve adjustment. If the sounds get louder when you press the gas pedal, you need to go to a specialist. Problems may arise in the connecting rod or crankshaft bearings or in the cylinder pistons.

Tuning VAZ engines

Engine tuning is carried out for the reason that VAZ cars are simple and unpretentious to maintain, but the factory settings do not allow maximum use of the engine's resource. You can independently increase the power of the VAZ 2114 engine and increase its acceleration speed by using basic methods.

1. Increasing engine power by increasing engine displacement. With this effect, it is possible to increase up to 15 horsepower to the existing engine power.
2. Fine tuning of the fuel injection system. There are two main ways: replacing the factory engine power supply system with a more expensive one and replacing the carburetor circuit with a gasoline injection system. The advantages of the gasoline injection system are better mixing of fuel with air, which improves the combustion of gasoline and leads to a reduction in its consumption.
3. Installation of an aerodynamic air filter. The design of the filter is such that air passing through it experiences the minimum possible resistance and enters the mixer with less effort. An increase in power is possible by 5% with minimal effort from the car owner.
4. Adjusting the motor head. This method, like the previous one, is based on reducing the resistance to the movement of air flows in the places where the cylinder openings combine with the collectors.
5. Engine chip tuning. This is done by changing the settings of the electrical control unit for fuel injection and ignition system. Available exclusively for vehicles with direct injection engines.

More than three decades on the road

It is quite difficult to meet the model in question on the road today. This is due to the fact that many models are already more than 2 decades old, during which they have been used on the harsh roads of the CIS. Over such a long period of time, the upholstery and other elements of the interior became unusable. Also, do not forget that at that time poor quality speakers were installed for radio playback. Also, the instrument panel requires significant improvement - it is quite difficult to read information at night.

If you can put up with some problems in the interior, then you should deal with a lot of noise in the cabin while driving. Many owners of this car note that after being in the car for several hours, the car starts to hurt. The hum and vibration, especially after overcoming the 70 km/h mark, is very disturbing to both the driver and passengers.

In winter, the cabin is very cold; the body does not contain the heat emanating from the stove. That is why in winter, comfort when driving a “penny” drops so much that an emergency situation is created.

The above information indicates that VAZ 2101 interior tuning consists of the following points:

• We are replacing worn and frayed panels and sheathing materials. If possible, you can replace the installed seats, as this will increase comfort and make the interior more attractive.
• It is necessary to carefully work out the insulation of the car. There is quite a lot of work here, since factory insulation is almost completely absent. However, without completing this step, you should not expect that the car’s interior will be comfortable.
• Many owners of such a car install new speakers and significantly increase their number. To achieve good sound quality, you need to position the speakers correctly, which will require altering the side panels of the doors. In addition, a place is created for the radio.
• If desired, you can change the instrument panel or the entire panel. Such work also significantly changes the appearance of the interior.

In general, we can say that there are a lot of ideas for improving the interior of the “penny”. It is worth considering the fact that it is relatively small in size. Therefore, to increase comfort, you can make various drawers and pockets.

CHIP tuning of VAZ 2114 injection engine

Zero resistance filter

The concept of “tuning” appeared in Russian everyday life several years ago, and translated from English meant tuning or adjustment. Today it is:

• improving the appearance of the entire car;
• change in its power;
• conversion of factory settings, etc. This procedure allows you to make the car unique and should be carried out according to the personal requests of the owner.

Most car enthusiasts consider this a whim, but drivers who have tuned the VAZ 2114 engine say that the car began to behave differently, this is especially noticeable at lower speeds. The power of the engine increases, the car picks up speed better, acceleration to 100 km/h occurs faster, and the driving dynamics become greater. This is a huge advantage when overtaking on the highway, when you need to give sharp acceleration, as well as in the city when maneuvering in traffic jams.

Why do you need chip tuning?

Today we will talk about chip tuning for the VAZ 2144, which affects the behavior of a passenger car on the road, changes the dynamics and declared engine power, and also allows you to use the unused “talents” of the car. Such changes can only be made in those machines where “brains” or an electronic control unit with a microcircuit are installed. This type of updating your iron friend is the most popular and widespread. After this, engine operation becomes more forced.

There are a lot of specialists who advertise reprogramming services, but here it is worth remembering that flashing the VAZ 2114 firmware should be performed by professionals for whom your order is not the first “hack job”. You also need to be sure that in addition to knowledge and skills, they also have the necessary equipment - a programmer. Improperly performed work will not only not improve the vehicle's performance, but may also require replacement and repair of electronic systems, and therefore incur additional costs.

Engine ECU VAZ 2114

The average price starts from 1500-2000 rubles and depends on the year of manufacture of the updated vehicle, but it is possible to carry out chip tuning of a VAZ 2114 with your own hands. In addition, to improve performance, there is no need to replace the engine with a turbocharged one, which also reduces costs and does not require re-registration of the vehicle's passport, and also allows you to easily undergo annual technical diagnostics (inspection) of the car.

Flashing changes the parameters set by the manufacturer. But its task is not only to change, but sometimes to remake poorly configured data. Thanks to this, control and adjustment of fuel supply, ignition systems, air supply and other modes become more advanced and can already comply with Euro 2 and 3 standards, which is bottled in our gas stations. Reprogramming also helps very well when the catalytic converter breaks down, eliminating this error.

How to properly perform chip tuning with your own hands?

To update the program qualitatively, you need to decide what tasks you set for yourself.

1. To improve all characteristics, you need not only to flash the brain, but also to do additional actions, such as replacing the air filter. This will increase the engine power of your car by 5-10% at once. The first visible drawback of such improvements is increased fuel consumption, but the figures level out after some time.
2. After replacing the filter, the panel with microcircuits is removed from the electronic unit, which is connected to the programmer, which enters the required information and updates the software.
3. These are minimal changes, and after installing the electronic board in place, you can try another power of your “swallow”.

It is also worth considering that chipping allows you not only to increase power, but also to set the engine modes to economical, starting or transitional. As mentioned above: it all depends on the desires and capabilities of the client.

Where can I find the programmer?

The programmer can be bought in many online stores with delivery, and its task is not only to flash the car’s brains, but also to diagnose engine problems, as well as remove errors that arise. Their cost varies, as do their functional characteristics, which depend on your desires and requests. But for the sake of one-time manipulations with the engine, it is not worth purchasing it; it is better to contact car workshops and auto electricians, and better on the recommendation of friends. It would also be a good idea to read reviews about automotive specialists and companies on specialized forums. A competent specialist may advise changing the settings for the toxicity of exhaust gases, as well as converting the ignition system timing parameter.

If you are still asking yourself the question “Is it worth making changes to your car or not?”, then the answer is a clear “YES”. And it’s better to start with chip tuning of the VAZ 2114 engine. With small financial and time costs, your iron horse will become 15 percent faster in total and will delight you with fast acceleration. When the car is fully loaded, it becomes easier to maneuver, and dynamics and acceleration increase.
The only advice: you should not make engine improvements if the car is still under warranty and service, as this may reduce or void the warranty period.

Interior tuning

As has already been mentioned several times above, “kopeks” are already very old cars, veterans of Russian roads, and therefore the condition of the interior, as a rule, leaves much to be desired.

Tuning the dashboard of VAZ 2101

Auto-tuning experts claim that there are two main ways to improve the dashboard of a VAZ 2101 - install a torpedo removed from a foreign car, or a torpedo from a more modern “relative”. In the first case, the BMW E30, equally beloved by all tuners, would be the best choice, in the second - the domestic “five”, “six” or “seven”.

First you need to dismantle the old dashboard. For this:

1. Remove the instrument panel.
2. Remove the glove compartment shelf.
3. Remove the fasteners that secure the panel to the engine compartment.

Installation of a new torpedo is carried out in the reverse order, but there are a number of nuances here. For example, if you are using a torpedo from a “seven”, it will be necessary to make some changes to the car’s heating system, since it is different for the two cars.

Which material to choose

There are four main materials used for upholstery of car interiors - leather, faux leather, Alcantara and velor.

Leather is the most durable material that will last a very long time and give the interior a sophisticated look. However, you will have to pay a lot of money for all this.

Leatherette allows you to create an expensive, status look, but at the same time it costs much less and is less demanding to care for.

Velor is a soft, velvety material. It can be called quite capricious: it does not like moisture. In addition, problems may arise if soiled: velor cannot be washed with soapy water.

Alcantara is the optimal choice for upholstering the interior of a VAZ 2101. Alcantara is a synthetic material that looks like suede. The softness and texture of suede are complemented by the most advantageous features of artificial materials - wear resistance, ease of cleaning, etc.

Seat reupholstery

Reupholstering the seats of a VAZ 2101 is a painstaking and rather complicated job. Sequencing:

1. First you need to dismantle the seats.
2. Squeeze out the iron clips on the back of the seats and remove the “original” covers.
3. Rip the cover apart at the seams in order to later transfer it as a pattern to new material. In this case, you should label the parts of the cover so as not to get confused later and sew the new cover correctly.
4. Each part of the old cover must be pressed tightly against the new material; it is advisable to place a weight on top or secure it with pins. Trace the outline and cut out the details.

Do-it-yourself VAZ 2101 door cards

Door cards (door trim) wear out over time and can even sag. In this case, it is worth making new ones. The most economical option is to make them from a sheet of plywood. So, to make new VAZ 2101 door cards you will need:

• plywood sheet 4 mm thick;
• jigsaw;
• scissors;
• glue (we recommend Mah, a German-made glue designed specifically for auto work);
• foam;
• textile.

The work is carried out in the following sequence:

1. First you need to remove the old door trim, attach it to a sheet of plywood and trace it.
2. Cut a new plywood frame along the contour with a jigsaw, not forgetting to make holes for the door handle, window handle, etc.

How to increase engine power in a VAZ 2114

In order to increase the power of the VAZ 2114 engine, you must first understand how this engine works. The VAZ 2114 piston internal combustion engine is a kind of large pump. It is capable of absorbing air and fuel, burning it inside itself. As a result of combustion, thermal energy is generated, which the engine converts into kinetic energy. This kinetic energy then causes the wheels to spin. Knowing the operating principle of the VAZ 2114 engine, you can increase its capabilities. Experts will tell us how to increase the power of the VAZ 2114 engine.

If you tune the VAZ 2114 engine, and also convert 8 valves to 16, then the engine power will exceed your expectations. To do this, you need to take into account all the subtleties and details.

In order to increase the power of the VAZ 2114 engine, the main goal of tuning is the following:

— the resistance of the gas distribution mechanism must be reduced;

— the absorption (pumping) capacity of the engine must be increased;

— It is also necessary to improve the purging of the cylinders.

Firstly , first you need to install the throttle valve.

It will reduce the resistance that the air-fuel mixture encounters on its way into the cylinders. To do this, it is necessary to increase the diameter of the throttle valve. Also, for this purpose, it is necessary to increase the diameter of the channels and valves of the cylinder head or install multi-throttle intake manifolds on each cylinder.

Secondly , it is necessary to increase the volume of fuel combustion chambers. If there is a large volume, then the pressure difference will be greater. This difference in atmospheric and internal pressure increases the rate of penetration of air, and therefore the fuel-air mixture, in one stroke. The more of this mixture, the higher the engine power. This can be achieved by increasing the diameter of the cylinder and piston.

Power point

“Kopeyka” is a car whose tuning can be so irrational that it causes true admiration and bewilderment. The low cost of the original can be increased tenfold by bold and comprehensive tuning. The engine occupies a dominant place in the life of a car. As you know, the original installation could not boast of particularly outstanding parameters.

Therefore, many people start tuning a “penny” with the engine. If you do not approach this issue globally - simply replace the engine, increasing the displacement is the main way to refine the power plant. You can simply bore the cylinders to the maximum size or install shortened connecting rods, which will increase the volume of the combustion chamber. At the same time, many people change the camshaft, installing an analogue from Niva. In any case, this will not bring dramatic improvements.

How to increase the power of a VAZ 2114

The content of the article

• How to increase the power of a VAZ 2114
• How to increase engine power in a VAZ 2109
• How to increase the power of a VAZ carburetor engine

The greatest effect is achieved by the integrated use of several methods for increasing the power of the VAZ2114. Typically, the essence of the intervention in the engine lies in 3 points: increasing the total volume of the cylinders, increasing the absorption capacity of the engine, and improving the purging of the cylinders. Each method is worth understanding in more detail.

Volume increase

At first glance, everything is clear - more volume, more power. To increase it, you will have to change the crankshaft, pistons and connecting rods, and bore the cylinder block. The volume will increase due to the increase in piston stroke. However, this method has a serious disadvantage - an increase in friction, which will lead to faster wear of the cylinder-piston group (CPG). To somehow compensate for this drawback, many use lightweight pistons on the VAZ2114 (they simply shorten them by cutting off the skirt). Boring the cylinder block will reduce the maintainability of the engine. Also, do not forget that an engine tuned in this way will become less revving.

Increased absorption capacity

In order for the engine to “absorb” the fuel-air mixture faster, on the VAZ2114 it is necessary to remake the air damper (increase its diameter). This will significantly reduce the resistance on the way of the mixture into the cylinders. The second part of the work to increase the absorption capacity of the engine is to increase the diameter of the cylinder head valves and the corresponding channels. As an option, you can install a multi-throttle intake manifold (one for each cylinder).

Scavenging

Here, already tested technology in the form of turbocharging is most often used. Today, manufacturers offer many ready-made, assembled kits, which are not difficult to install and will significantly increase engine efficiency. However, it is worth remembering that the device is not cheap, and also requires maintenance during operation: you will have to change the oil and take other features into account; for example, you cannot suddenly and immediately turn off the engine. Another disadvantage is that the turbocharging begins to work after reaching 2.5-3 thousand revolutions, so when driving in the city it is almost useless.

Another option for purging the cylinders is to install a compressor. This is a much more effective method - the compressor starts working from the lowest speed. The main disadvantage is the complexity of installation; you can’t do it without a good locksmith. Compressors are easy to maintain, but have a lower efficiency compared to turbocharging. As an addition, after improving the purging of the cylinders, a direct-flow muffler can be installed, which will facilitate the rapid removal of exhaust gases.

From the history of VAZ

The main differences between the VAZ - 21011 - 013 and the VAZ - 2101:

Dimensions in the headlights; the sidelights contain only a direction indicator, the orange lenses have a flat profile; a larger number of vertical bars in the decorative radiator grille; ventilation holes on the rear pillars; new bumpers with protective rubber lining without fangs; holes under the radiator grille for better ventilation; rear reflectors are integrated into the new shaped lights; a reversing light appeared under the rear right lamp; the inscription “Zhiguli” has been changed and moved under the left rear light; wood trim on the dashboard; torpedo with fewer decorative ribs on the panel; instrument panel with black background; new design door trims without pockets; plastic handles for opening doors and windows; The upholstery pattern and seat shape have been changed.

Engine tuning VAZ 2114 8 valve injector

The domestic auto industry produces many worthy models that are affordable and of quality.
But still, some cars have their drawbacks. For example, many modifications of the Lada (including the 14th) are distinguished by a rather weak engine. When faced with this problem, car enthusiasts often choose to improve the car on their own (or at a service station), in other words, to tune it. There are many methods for increasing engine power that you can implement yourself. To maximize the machine's capabilities, new cylinders must be added. But this is the most radical and expensive method; experts advise doing without it or contacting a specialist car service center.

General information about the VAZ 2114 engine

There are three modifications for this model. If you are asking yourself the question of where to start tuning a VAZ 2114 engine, then first you need to understand what material you will have to work with. There are the following types:

1. Eight-valve 1.5-liter engine.
2. Eight valves, but with a volume of 1.6 liters.
3. Sixteen valves with a volume of 1.6 liters.

Most often today you can find the second option. However, compared to the first point, this engine gained only 4 horsepower, which can hardly be called decent power in our time. Any repair shop provides a tuning service.

Experts will say that the most inexpensive way to “accelerate” a car is to install a zero-resistance filter and an enlarged throttle valve. It is also possible to install a sports camshaft (increase power by 20%). You can go a more complicated route, replacing many parts with lightweight ones (pistons, connecting rods, crankshaft).

Ways to increase power

Having decided to tune the VAZ 2114 engine, you need to act on the principle of “do no harm”, because some modifications can negatively affect the functioning of the car. Therefore, if you do not have experience in replacing parts under the hood, then it is better to choose the most gentle changes. These include:

• increase in cylinder displacement;
• replacing the standard air filter;
• installation of a turbocharger;
• chip tuning.

The first method is one of the most reliable and effective. After preliminary diagnostics, which will provide detailed information about the parts and internal systems (carried out at any service station), you need to correctly bore the piston, change the intake manifold and crankshaft. Without a machine and tools, this operation will not be possible. After all, if you sharpen the piston incorrectly, literally making a mistake of a couple of millimeters, the results will be catastrophic. From a financial point of view, such an operation will cost about 400-500 dollars in a workshop, but the power will increase by 1.5 times. Unfortunately, fuel consumption will also increase along with it.

Alternative methods

An easier method is to replace the air filter. Fuel consumption does not increase here, but power increases by 10%. Along with this procedure, you can remove roughness on the cylinders and grind the intake channels. In other words, carry out a “spring cleaning” of the VAZ 2114 engine. But you need to be careful when installing a turbocharger. Despite the apparent ease of installation and standard equipment (such a part can be bought at any car market, just knowing the model of your car), this system will place a very large load on the transmission.

The simplest option is chip tuning. We are talking about reprogramming the engine computer system. Today there are a lot of tools, each of which changes a certain aspect of the work. For example, you can reduce fuel consumption, increase acceleration power, and so on. But here you cannot do without special equipment - a programmer. But after installing the electronic board on the engine, you can independently and repeatedly change the parameters.

Fuel supply system

When doing deep tuning of the VAZ 2106 engine, it is advisable to replace the carburetor with an injection fuel supply system. You can install a more productive Solex carburetor, select jets, etc. But the point is that this car unit is very capricious.

Its operation is affected by the quality of gasoline, the atmospheric air supplied to the system, and even the location of the car relative to a horizontal surface. By installing the injector, you will notice many new positive qualities in your car, namely:

• Mixing of fuel and air occurs directly in the combustion chamber, which allows you not to lose up to 10% of engine power.
• The increased dynamics of the car is due to sensor monitoring - when the load changes, injection is instantly regulated.
• No need to warm up in winter, easier starting compared to carburetor cars.
• High reliability and long service life.
• Greater environmental friendliness.
• In 1.5-2 years you will fully recoup the cost of the injector due to the saved fuel.

Installation of this system can be done by yourself. The main thing is not to forget to lay another fuel line for the return.

And don’t forget about one more thing when tuning the engine on a VAZ 2106: the throttles must be replaced with a throttle unit, into which the corresponding dampers and idle air control are installed.

How to increase the power of a VAZ 2114

The VAZ 2114 car has three engine modifications. Initially, the production of the fourteenth was carried out with an eight-valve 1.5-liter engine, after which eight-valve engines with a volume of 1.6 liters were developed. 16-valve 1.6-liter engines were then on sale for some time, but their production quickly ceased. Currently, VAZ 2114 cars only with 8-valve 1.6-liter engines. This motor's technical characteristics are almost identical to previous versions. Compared to the 1.5-liter, the power of this engine increased by only 4 hp. It seems that the AvtoVAZ developers, having turned to increasing the service life of engines, forgot about such an important parameter as its power. In this regard, car owners are independently trying to increase the power of the VAZ 2114 . Some craftsmen even managed to develop 140 hp. from a VAZ 2114 engine, which is twice the factory specifications. However, with an increase in engine power, its service life decreases. So let's talk now about how to increase the power of the VAZ 2114 engine and not significantly shorten its life.

Output result

All of the above manipulations with your car will lead to the fact that upon completion of the work you will be the owner of a Zhiguli car. “Kopeyka” will essentially remain what it was. Moreover, regardless of the amount of effort and money invested. That is why many who are so enthusiastic about tuning “penny” cars, upon completion of work and after a couple of months of operation, put up their miracle car for sale.

Therefore, when starting work, be sure to ask yourself what you want to achieve with it. Perhaps you just needed to buy a new car? And you did the tuning. Think about it.

We perform tuning of the VAZ 2114 engine with our own hands

In its factory form, the VAZ 2114 engine does not develop all its potential power. Therefore, how you can tune a VAZ 2114 8-valve injector engine with your own hands is of interest to many owners of this car.

VAZ 2114 engine

How does the VAZ-2114 engine work?

The main feature of this type of engine is the presence of an injection system. The engine is four-cylinder, with two valves (intake and exhaust) on each of the cast iron cylinders.

Several types of engines were installed on the VAZ 2114. The 8-valve engines that can be found on this car model include:

1. VAZ-2111 - its volume is 1.5 liters, maximum power is 78 hp, maximum torque is 116 Nm.
2. VAZ-21114 – 1.6 l, power 80-84 hp, maximum torque – 125 Nm.
3. VAZ-11183 - 1.6 l, maximum power 81-82 hp, maximum torque - 132 Nm. This type of engine is also available with 16 valves, but we are considering an 8-valve one.

The service life of the VAZ-2114 engine, according to the manufacturer, is 150 thousand km. With careful handling and modification of the engine in a safe way, this resource can be extended.

In order to improve the power and other performance indicators of the engine, it is necessary to modify it - tune it.

How to increase engine power

There are various ways to modify a VAZ 2114 8 valve engine at home. They can be used either separately or in combination, depending on the desired result.

Increasing the volume of engine chambers

There is a direct proportional relationship between engine size and power. The most popular option for the VAZ-2114 is to increase the volume from 1.5 to 1.6 liters. (or from 1.6 liters to 1.8 liters depending on the specific engine model). To increase volume, you need:

• install a lightweight crankshaft;
• replace the pistons with forged ones and replace the piston rings with lightweight ones;
• change the connecting rods that connect the pistons to the crankshaft;
• increase the diameter of the cylinders and grind the surface (this is done to increase the number of crankshaft revolutions).

As a result, the engine power increases by about one and a half times. But this also increases fuel consumption.

It is also necessary to replace the oil nozzles - forged pistons require oil cooling. And in the process of boring parts, old injectors become unusable.

Installing a new air filter

To increase engine power, an intake filter with reduced aerodynamic drag is used. As a result, air enters the mixer with less effort. This can add an additional 5-8 horsepower to the engine. At the same time, fuel consumption is reduced.

To tune the intake system, you need:

• polish the internal intake channels (done in car repair shops);
• install receivers;
• install a throttle valve with a larger diameter.

The exhaust system is also modernized by installing a direct-flow muffler.

Important! Boring and grinding of intake channels should not be done at home. This work requires increased precision, so it is better to contact a specialist for this.

Turbocharging installation

This is one of the most effective, but at the same time costly, methods for tuning the 2114 engine. The increase in engine power depends on the type of turbine used:

• low pressure turbocharger – increases engine power by 15%. This is the least labor-intensive option for installing a turbine;
• high-pressure turbines - increase engine power by 25-30%.

If a turbine is installed on a VAZ-2114, there is a high probability of premature exhaustion of the engine's life. This is due to the fact that all working elements wear out ahead of schedule.

Some nuances to consider after installation

Engine torque and power. What is more important A few words about speed. In simple words formulas and videos

Like any other complex system, a turbocharger has features that are strongly recommended to be taken into account when operating it. Moreover, a negligent attitude to these requirements can reduce the service life to a minimum and the costs of tuning will never pay off.

Here are some highlights:

1. It is necessary to monitor the oil and filters. Change it in a timely manner and do not use additives.
2. It is advisable to use only oil recommended by the manufacturer.
3. Avoid sudden starts with heavy loads.
4. Avoid abrupt engine stops under load.
5. Avoid idling for long periods of time.
6. Tightness.
7. Change the air filter promptly.

Specifications

The “2101” engine, the ancestor for all models, is carburetor. The camshaft has an overhead position. Chain timing mechanism drive. The engine life is more than 18 thousand kilometers. The assembled engine, together with the clutch and gearbox, is attached to the front and rear cross members through three shock-absorbing mounts. The clutch is dry, permanently closed, single-disk. The suspension is independent with a spring and telescopic shock absorber.

Specifications

Modifications

• 2101 - Basic model. Four doors. "Sedan". It was produced in very small quantities as a “limousine” and a “pickup.” Power 58.7 l/s.
• 2102 - "Universal". Issued since 1971 to 1985 For transportation of goods and passengers. The springs and shock absorbers of the suspension are reinforced. The rear seat is folding to increase the luggage compartment. The low level of the outer trunk wall made loading and unloading easier. Power 62 l/s.
• 2103 - interpretation of “penny”. 1972 — 2005 (Export version of Lada 1500). Luxury interior and trunk. Power 77 l/s.
• 2105 - The model marked the beginning of the second generation VAZ cars. The exterior and interior have been modernized. For the first time, the timing belt drive. Heated rear window and defrostered door windows. Five-speed gearbox. 1983 — 2010 75 l/s.

Possible breakdowns and their elimination

The VAZ 2101 engine is quite capricious, difficulties constantly arise in operation, this happens so regularly, and breakdowns are so stereotypical that you can make a list of causes and effects that will be accurate in 99% of cases:

• If dense smoke comes from the exhaust, this indicates a malfunction of the bushings and guides, and may also be a symptom that the seals have failed;
• Large oil leakage from the engine. In the case of the classic, for which the consumption of 700 grams of oil per ten thousand is the norm, great care is an elastic concept. However, if the oil “leaks” the reasons for this are wear of the piston group, or wear of the sealing gaskets. If during a visual inspection no leaks are found, the situation is bad, this means that the 2101 engine needs a major overhaul;
• In cases where the engine overheats, we are talking about a failure of the cooling system: you need to check the fan, water pump and thermostat. One of these units needs to be replaced;
• Also, the engine may knock, and this knock will be heard even from the side - this is due to loose valves. It is necessary to disassemble the engine and carry out their adjustment.

Touching upon such a topic as repairing a VAZ 2101 engine, one cannot fail to mention the carburetor and ignition system. These two wonderful units fail so often that you can devote more than one wonderful evening to adjusting their operating parameters. It is best, in the context of tuning, to install an electric ignition system on the classic engine to save yourself time and nerves.

By the way, decreased power absolutely indicates wear of the piston group.
