How to increase the power of a VAZ-2114 8 valve engine

What engines were installed on the VAZ-2114

The very first engine used on the VAZ-2114 was an injector with 8 valves and a volume of 1.5 liters. It is one of the most common on this car model, as it was installed on the VAZ-2114 for 6 years. Their series was designated: VAZ-2111, units with it had a rather modest power of 77 “horses”.

In 2007, the production of the “fourteenth” models was modernized, which gave motorists an updated engine. It had 16 valves and a larger volume of 1.6 liters. The series of this engine is VAZ-11183-1000260.

In addition to more modern characteristics, this power unit has received the Euro-3 environmental standard. However, engine power increased only in 2009. The first versions of this engine were with 77 hp.

With. , and then their strength increased to 89.

In 2010, the VAZ-2114 again received a new engine. It had 8 valves and a volume of 1.6 liters, exactly the same one was installed on the Priora. Significant modifications to this engine helped it reach 98 horsepower.

Many car enthusiasts were interested in why modifications with 16 valves stopped coming off assembly lines. The need to change the power plant was associated not only with an increase in power, but also with the fact that when the timing belt broke in the previous model, the valves were bent.

What all powerplants have in common is that they use the same fuel injection system. Before entering the cylinders, the fuel passes through the nozzles in all modifications, and the installation is cooled using liquid. Well, the last similarity is that all units are four-stroke.

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.

Basic engine malfunctions

All modifications of VAZ-2114 engines have a number of characteristic breakdowns. The most common are:

Floating engine speed at idle. Most often, this problem occurred on new cars and was corrected under warranty. The cause is most often a malfunction of the throttle position sensor, idle speed control or vacuum unit.
The same reasons lead to the car stalling while driving. An additional problem in this case is the incorrect operation of the mass air flow sensor.
During operation, the power unit froze. First you need to measure the compression in the cylinders; if it is low in one of them, the cause is burnt valves or a head. With the same difference in compression, the problems are hidden in the valve pressure settings or their gasket. If there are no deviations, then you need to check the ignition module.
Failure to heat up to operating temperature (from 87 to 103 degrees) is due to a faulty thermostat.
Engine noise occurs due to unadjusted valves. If it intensifies when you press on the gas, then you need to check the connecting rod bearings or cylinder pistons.

If it seems to you that the power plant has lost power, then you should look for other symptoms. They are the ones who will tell you why it does not develop speed and does not meet the stated characteristics.

The main mistakes made when tuning

Many people try to add power to the engine, but at the same time make typical mistakes. The leading ones among them are:

installation of cutters in garage conditions (this work requires high precision);
use of unnecessary and expensive spare parts;
lack of suitable firmware for a sports camshaft or other elements.

Before buying expensive spare parts, you should pay attention to the recommendations of the specialists. They created a list of useless components:

A receiver with an increased volume is good only at medium and high speeds, but for work in the range from 1000 to 2500 rpm, a standard spare part is more preferable.
A zero filter, called a “chandelier,” is a fairly useful addition, but you will have to constantly clean it with special chemical compounds. This will increase the cost of maintaining the car.
A throttle valve of increased diameter does not increase power too much, since the engine always has enough air.

Tuning an injector with 8 valves

To increase power from 77 to 96 horsepower of the very first engine of the VAZ-2111 model, you need to do:

boring valve seats along the inner diameter;
boring the channel necks for installing duralumin plates and loosening the springs by 1.5 millimeters;
replacing standard valves with lightweight ones;
recessing of guide bushings from special brass;
installation of a split timing gear;
use of imported valve cotters;
installation of a narrow-phase shaft.

The tuning shaft has an inlet of 70 degrees and an outlet of 66. Its opening angles are 250 and 246 degrees, respectively. After completing the work, it is necessary to install the engineering firmware and carefully configure the motor parameters. Only in this case, after all sensors are turned on, the engine will start working normally.

It is better to use a split gear on non-plug-in motors. For installation, it is necessary to carry out the work in almost the same way as when replacing the timing belt, that is, apply marks, disassemble the mechanism, and align the crankshaft. After installing the new gear, pay attention to the 4th cylinder. If the valves in it are not open to the maximum, in this case you will need to loosen the outer screws and adjust the camshaft, after which you need to tighten the fasteners.

Method for increasing the power of an 8 valve engine with a split gear

The split, that is, adjustable gear was not used in the last project. It is better to install it on “non-plug-in motors”. Setting method:

The moving and fixed parts are marked with a mark, the same as on a standard pulley;
Installation is carried out in the usual manner, aligning the crankshaft and timing mechanism according to the marks (as when replacing a belt), you should also remember about the correct tightening torque of the belt;
If in the 4th cylinder the intake and exhaust valves are not open “to the maximum”, we carry out an adjustment: loosen the outer screws, and, holding the outer part of the gear, set the camshaft correctly.
Tighten the fixing screws. Split gear with retaining screws removed

Increasing the power of the VAZ-11183 engine

The engine of this modification cannot be modified without changing the ECU. From the factory it was equipped with an M74 block, which needs to be replaced with Yantar 7.2. It is also necessary to abandon the e-gas function, which will require replacing the receiver and throttle assembly. Borrow the intake tract from the modification of the 2111 engine, and replace the electronic pedal with a standard cable pedal.

The Yantar controller has already been time-tested and works fine, but only if you have not replaced the camshaft. You can supply a part with the following parameters:

release phase – 104;
intake - 109 degrees;
for release, the opening angle is 272;
inlet - 268;
valve travel – 9.5/10.1 (inlet/exhaust) mm.

After this, you can pass the limit of 90 “horses”, but you will have to sacrifice reliability. If you want to increase the power of the power plant, remember that this will reduce its service life. With proper care, a stock engine can cover over 250 thousand kilometers, but with a tuned one there is no guarantee that the mileage will exceed 120 thousand.

You carry out all work at your own peril and risk. You should not start them without having the necessary knowledge, because in this case you will have to carry out a major overhaul of the power unit, which will require additional investments.

Recently, many car enthusiasts, especially representatives of the younger generation, are improving their “iron horse” through tuning procedures.

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.

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.

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.

VAZ 2114 engine ECU 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 the 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.

We recommend: Replacing the front and rear crankshaft oil seals on a VAZ 2114. Reflashing 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.

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.
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.
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.

Ways to increase power

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.

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.

We recommend: Measuring compression in the cylinders of a VAZ 2114 engine. 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.

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 in the VAZ 2114 was the 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 is 127 kg. The resource of the unit according to factory data 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.

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.

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.

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.
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.
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.
The engine does not reach normal operating temperature. The reason lies in a faulty thermostat.
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.

Increasing engine power by increasing engine displacement. With this effect, it is possible to increase up to 15 horsepower to the existing engine power.
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.
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.
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.
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.

Selecting the number of engine valves

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.

16-valve engine 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. 16-valve engine (1.6 l) or 8-valve (1.

5 l) are 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.

When upgrading the engine of a VAZ car, as a rule, several methods of increasing engine power are combined simultaneously. The choice depends on what engine resource needs to be increased. You should refrain from wanting to increase power by more than 30%. If this is not taken into account, then the cost of maintaining the car will increase, which will “block” the effect of the tuning.

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.
