Engine tuning: Niva 4x4 - increasing power using common methods

Let's look at the example of NIVA 2141 Lada 4x4, how you can increase hp power with the help of additives and oil additives.

NIVA is designed for off-road use, and its engine is not the most powerful for acceleration, overtaking or driving uphill.

Here under the hood there is an 8-valve 83 hp. engine injector.

But it drags well when driving in mud, slush, deep snow and steep ruts. But they also drive it on the highway, and here the performance is not the most outstanding.

When pressing the gas pedal, I would like to get better acceleration.

And this can be done without boring the motor to increase power.

And with the help of an effective additive for a sharp increase in torque, rapid fuel combustion.

But to get a result plus 5 - 6 hp, you need to do everything comprehensively. Firstly, after purchasing a LADA, you need to drain all the fluids in all components that were filled from the factory. Change everything in the box, in the engine, in the axles, in the transfer case, especially the antifreeze.

Not the best oils are used to protect parts from friction and wear.

Replacing engine components

If we consider the Niva in relation to the new years, then we should take into account that engine tuning comes in two options:

• Chip tuning.
• Mechanical modification.

Recently, chip tuning has become very popular, which allows you to significantly increase the power indicator in the shortest possible time. However, this tuning method should be treated with some caution, which we will discuss in more detail later.

Not all SUVs of domestic origin have an on-board computer. At the same time, we should not forget that some on-board computers are in poor condition and in fact do not affect the operation of the engine.

When considering this tuning method, we note the following points:

• You can increase the power by about 10-30 hp. or more. It all depends on what parameters were set before tuning.
• It is recommended to entrust this type of work to specialists who provide services in this field of activity. This is due to the fact that incorrectly carried out chip tuning can cause various problems with engine operation.
• The technical condition of the internal combustion engine design largely determines whether chip tuning can be carried out. If the motor is in poor technical condition, then increasing the load causes rapid wear. Therefore, if the process in question is carried out correctly, a complete diagnosis is first performed.
• As a rule, the automaker sets minimum power values, leaving a margin. If chip tuning has not been carried out previously, the programmer will be able to configure the engine to increase its power. If the modification in question has already been carried out previously, it will no longer be possible to carry it out again.

In general, we can say that chip tuning is carried out in many cases when it is necessary to increase engine power. However, in order to significantly increase traction, it is necessary to improve the geometry.

Modernization of the off-road features of the Chevrolet Niva contributes to a significant expansion of the vehicle’s capabilities:

• the upper shock absorber mounts are strengthened;
• The fastening of the upper bolt holding the front axle gearbox is being modernized.

Additionally, you can install a hydraulic power steering control, double or gas springs instead of the standard ones. All this is quite expensive, but if you do this tuning, you will never regret it.

The appearance can be significantly changed using the following details:

• front and rear bumper protection;
• thresholds;
• spoiler;
• kangurins.

You can see how tuned Chevrolet Nivas look in the photos or video clips attached at the end of the article.

Engine VAZ 21213 1.7 l. carburetor/injection (21214) in-line 4-cylinder with overhead camshaft, Niva timing belt has a chain drive. Based on the 214 engine, the VAZ 2123 engine is produced for the Chevy Niva; the differences in adapting the block for installing a pulley in the engine compartment and mounting attachments are technically almost identical.

The main differences between the VAZ 21213 engine and the 2106 are the cylinder diameter is 82 mm, the cylinder head, the Niva 21213 engine block from the 2106 is smaller in height. Among the advantages of the 213 engine, it is worth noting the presence of a chain tensioner (no need to tighten it) and hydraulic compensators (no need to adjust the valves).

The simplest modernization of a Chevrolet Niva engine involves replacing certain parts. First you need to bore the sleeves. After this, you need to select pistons and special ring-shaped elements that have a certain size.

The next step is to equip the engine with a crankshaft with larger arms and smaller connecting rods. The result of the above actions will be an increase in engine volume from 1.7 to 1.9 liters, and, consequently, power will increase.

It is also worth thinking about increasing the volume of fuel going to the cylinders. To do this, the cylinder head is modified, namely, the intake and exhaust ports are bored, the valve is replaced with a larger one, the valve seats are bored or completely changed.

Let's sum it up

There are quite a large number of ways to modernize the Niva engine, all of them have their own specific features. It would seem that replacing consumables with better ones is an insignificant upgrade, but it allows you to increase engine power by several tens of horsepower. More significant upgrades also improve the technical qualities of the engine, but do not forget about the increase in load, as a result of which its service life is reduced.

It is recommended to entrust serious engine modernization to professionals. This is due to the fact that even minor mistakes made can cause rapid wear and tear of the structure and render it unusable. If the engine is in poor technical condition, then attention should be paid to the possibility of completely replacing it: the amount of work and costs are reduced. The motor must be not only powerful, but also reliable, which should not be forgotten.

What can be improved in the Niva 4×4 model

Most representatives of the domestic automobile industry require high-quality improvements, and Niva is no exception. Tuning can significantly improve many parameters of an SUV, from the interior to pumping the chassis.

Changing the suspension helps increase the vehicle's passing ability. You can also change the external design of the body, making it more modern and original. Many people try to increase the power of the power plant by tuning the engine.

https://www.youtube.com/watch?v=ytcopyrightru

Most often, supporters of updates turn to professionals for help, although tuning a Niva 4x4 with your own hands is quite possible. You just have to take into account that remodeling a car will require significant costs and certain skills.

The small SUV went into mass production in April 1977. Today the VAZ 2121 is a passenger car with increased cross-country ability. Available in two body types: a three-door hatchback and a five-door station wagon. It has permanent all-wheel drive and a five-speed manual transmission.

Two-stage transfer case with center differential lock. High cross-country ability of the car is ensured by significant ground clearance (220 mm). The wheelbase is 2.2 meters. Earlier modifications were equipped with engines based on the engine of the sixth VAZ model.

When new modifications were released, the previous engine was replaced with a more powerful four-cylinder unit producing 81.9 liters. s., having a working volume of 1.69 liters. Average fuel consumption in mixed mode is 10 l/100 km.

Content

The most popular and widespread SUV of domestic origin can be called Niva 4x4. This car has been produced for many decades, once designed as the main transport for residents of difficult rural areas. Even with such serious competition associated with the emergence of a large number of different foreign cars, the model is in demand. This is primarily due to the relatively low cost and good cross-country ability of the vehicle. However, in technical terms, the SUV has long been outdated and is inferior to many analogues. That is why we will take a closer look at tuning the Niva 4x4 engine, increasing power using the most common methods.

The main ways to help increase strength indicators

The most effective and common are:

• The geometry of components changes due to the replacement of factory-installed engine parts
• The so-called chip tuning, the electronic control unit is reflashed
• Turbocharging is installed

All of the above methods are associated with significant financial investments, and help the engine become more dynamic, while increasing its power.

Let's look at all the methods in more detail

Tip 9: How to increase carburetor power

A carburetor is a special device in the power supply system of carburetor engines, which is designed to mix air and gasoline, which creates a combustible mixture. In modern cars, carburetor systems have been replaced by injection systems.

You will need

Instructions

1. In order to achieve maximum power, the carburetor at the inlet (drivers call it a “huge hole”) must have minimal resistance, since otherwise it will be difficult to achieve a good mixture and fill the cylinders at high and medium cycles. However, when the carburetor throttle valve is sharply opened, the speed of air flow and vacuum in the diffuser decreases significantly, and the amount of fuel sucked in decreases, causing the combustible mixture to become leaner. Leaning of the mixture leads to the fact that at low cycles the power tends to zero (this fact becomes more noticeable with huge D of the main diffusers).

2. By installing a standard SOLEX 073 carburetor, you get a wonderful increase in high and medium cycles, but at the same time increase fuel consumption, and besides, there is a failure in low cycles. Carburetor tuning in this case consists of increasing the flexibility of movement in high and medium cycles, achieving filling in low cycles, as well as in transition modes.

3. Increasing carburetor power is more important than simply replacing old jets with new ones with a huge cross-section. This, in addition to everything else, is a metamorphosis of calibration data, the “filling” of the carburetor, as well as the introduction of additional systems into the design of this device. To do this, drill additional metering channels in the carburetor body, then equip the carburetor with additional equipment and configure this device.

Note! To achieve maximum power on a sports car, several carburetors should be installed at once.

Helpful advice The uniformity of the distribution of the fuel mixture among the cylinders largely depends on the intake manifold. Often the reason for the uneven separation of the mixture lies precisely in the design errors made when designing the collectors. In order to solve this problem, it is enough to remove part of the partitions located between adjacent channels.

What else can be done to improve?

The low wear resistance and efficiency of an SUV engine of Russian origin determines that it is practically impossible to do without mechanical modifications. Many people call such work a change in geometry.

The internal combustion engine installed on the vehicle in question can have many systems modified. Experts recommend starting with upgrading the carburetor. This is due to the fact that due to the use of imperfect production technology, its efficiency is very low. Modernization is carried out as follows:

1. To begin with, it is recommended to replace the nozzle. The factory version is installed with 1 cam, but should be installed with 2 cam.
2. The pump accelerator should be updated.
3. All sharp corners that could cause turbulence in the air flow are removed.
4. Some craftsmen also clean accessible surfaces, reducing their roughness. Due to this, the efficiency indicator is significantly reduced.

Insert: Important: It is important to clean the carburetor structure from carbon deposits and dirt. To do this, use gasoline or a rag. If the dirt has become too deeply embedded in the surface, you can use special cleaning products.

Experts do not recommend chipping a naturally aspirated engine. You can further increase engine power if you try to increase the piston stroke. This can be achieved by installing another crankshaft with a stroke of 84 mm, suitable for the VAZ 2130

. The piston has a diameter of 82 mm, but the piston pin must be offset by 2 mm. After this, the working volume will become 1.8 liters.

In the future, if you bore the block to 84 mm. with the same crankshaft, the volume will become 1.9 liters. But that’s not all, in the future you can increase the filling capacity of the working cylinders. This is achieved by boring and installing valves with an increased diameter of their plates. This operation is quite complex and requires special equipment. It is also advisable to use lightweight connecting rods and then you can have about 100 horses at the output.

Lubricant supplied through the oil pump extends engine life. To improve the performance of the oil pump when tuning the Niva engine, you need to take another pump and cut off part of the housing with the parting plane from it. The thickness of this “pancake” should be about 11 cm. Using milling, cut off the excess and leave a thickness of 10 mm.

Next, do the following to remove chamfers on the edges of the teeth:

1. We compress, that is, remove, the drive gears.
2. We trim one of the gears by 0.75 mm on each side.
3. We cut the second gear to 11.5 mm (after trimming).
4. We repeat the operation with the remaining gears (driven).

Tip 6: How to increase the cross-country ability of the Niva

Even such a recognized all-terrain vehicle as the Niva sometimes needs fine-tuning so that its cross-country ability satisfies the owner. To do this, increase the ground clearance of the car, which in the basic configuration is not too large. The power suspension will protect the body from damage during impacts and will help jack up the car if it gets stuck.

You will need

Instructions

1. the Niva chassis , simply replace the wheels and tires. In the base, the car is equipped with not the best version of tires, because the main criterion when choosing it is low price. For off-road use, choose wide tires, with a huge number of stiffening ribs on the tread. It is desirable that there are special ribs on the sides, which are called lugs.

2. If it is necessary to increase the wheel offset, change the wheels to match the tire size, install a reinforced hub on double-row bearings, and on the hub stands made of a special alloy, which will help increase the wheel offset. When increasing the wheel diameter, change the main pairs of axles, increasing the gear ratio . It is easy to calculate the new gear ratio - to do this, find the ratio of the new wheel diameter to the old one and multiply by the initial gear ratio. From the available options for the main pairs, choose the set that is closest in terms of your collections.

3. If increasing the Niva ’s ground clearance by replacing wheels is unsatisfactory, lift the car’s suspension using special spacers for its elements. To do this, purchase a lift kit, which for the front suspension is a set of washers installed under the spring and the upper arm, while swapping the steering knuckle arms so that they can move normally and not touch other suspension elements. For the rear suspension, special cups are provided for the springs, which are mounted on top, and brackets are installed below, which extend the shock absorber by 5 cm.

4. To protect your car from possible damage, install a power body kit on it. As usual, it consists of a front and rear bumper, a guardrail and power sills. When choosing reinforced bumpers, consider the likelihood that you will have to lift the Niva on it with the help of a rack and pinion jack. When choosing a “kenguryatnik”, keep in mind that its main function is not to give a hostile appearance, but to protect the headlights and radiator. When traveling to the forest, install branch guards, which are cables stretched from the roof rack for the roof rack. They will truly protect your windshield.

DIY methods for increasing engine power

The simplest and most common ways to increase engine power:

1. Replacing standard engine components with tuning elements means changing the geometry of the components.
2. Installation on a power turbocharging system.
3. Chip tuning is a software re-flashing of the “brains”.

All of the above methods can “revive” the engine, increase dynamics and power, but financial sacrifices will be required.

The Niva car is not distinguished by hurricane dynamics and high maximum speed. Consequently, those who want to get more power and thrust from this machine have developed and tested various methods of engine tuning, differing in the difficulty of installation and use and the resulting result.

https://www.youtube.com/watch?v=upload

You will need

• The original Niva. The car must be in good working order and as less worn out as possible.

Instructions

1. You can independently increase the power of the Niva engine using the following methods: - install lightweight valves and their guides, a lightweight flywheel; - increase the cross-sections of the exhaust and intake channels of the cylinder head; - increase the cross-section of the intake manifold; - install a camshaft, which increases power and torque by medium and low cycles;

- install a direct-flow exhaust system; - install a sports (lightweight) timing drive. - install a zero-resistance air filter; - bore the engine cylinders (in order to increase the working volume). For a carburetor engine, a Solex carburetor with 24-26 mm diffusers is additionally installed instead of the standard one.

The ignition system is changing to electronic with a Hall sensor from more modern VAZ models. A motor with increased power will require the installation of a radiator with an increased cooling area. The described program allows you to remove up to 120 hp from a VAZ-2121 engine. When installing 2 Solex carburetors, it is possible to increase the power to 136 hp. 2.

Many specialized companies offer the installation of turbocharging for Niva and Chevrolet Niva cars based on the GARETT GT17 turbocharger. Installation cost is about 60,000 rubles. Result: an increase in power from 80 to 105 hp, torque from 120 to 170 Nm, and a slight decrease in fuel consumption. The source of the engine is preserved, the fuel quality is gasoline with an octane rating of at least 95, and maintenance is standard for turbocharged cars. 3.

Fine tuning of the motor control system with support for chip tuning. Metamorphosis of the program in the electronic control unit eliminates shortcomings made by the developers and not noticed during testing. For a standard Niva engine, chip tuning will give an increase in power and torque of 10-15%, for a turbocharged one up to 35-40%.

The key parameter of any internal combustion engine is its working volume, measured in liters. This value has a direct impact on the power developed by the motor. And the more powerful the engine, the more dynamic the car and the higher the ease of driving it.

You will need

• – machine for boring cylinder blocks,
• – new piston group.

Instructions

1. Boring a new engine makes no sense, except for those cars that are being prepared for participation in sports competitions. In all other cases, the cylinder block is bored during a major overhaul of the power apparatus. 2. Due to the fact that the cylinder block is bored using special industrial equipment, during advance preparation for this process, the engine is removed from the engine compartment of the machine. 3.

After completing this task, the motor is completely disassembled, and after this, all the parts from which it was recently assembled are checked. 4. The “bare” engine cylinder block is delivered by auxiliary transport to the workshop to an expert in boring the specified parts. The master, after researching and performing the necessary measurements of the internal surfaces of the cylinders of your block, will give recommendations on obtaining a repair piston group of a certain size, which, after purchase, is delivered to him, to the workshop. 5.

One of the options for increasing the engine power of a Niva car is chip tuning of the electronic control unit (ECU). Making changes to the software of the specified device optimizes the operation of the injection engine. As a result, the crankshaft rotation speed increases, operating fuel consumption decreases and engine power increases.

You will need

• – computer or laptop,
• – adapter,
• chip tuning software.

Instructions

1. It’s no secret that the firmware of the Niva car’s ECU, installed by the manufacturer in accordance with technical regulations, significantly limits the likelihood of its power plant. 2. Let's say the fuel-air mixture supplied to the engine cylinders is deliberately lean, although the engine was originally designed to work with a richer mixture.

But at the insistence of environmentalists, the supply of gasoline to the injectors was reduced. 3. In order to make metamorphoses to the existing engine operating parameters, you need to connect the computer or laptop adapter to the diagnostic connector of the car. Of course, the appropriate applications must be installed on the computer. 4.

Using the software, the operating parameters of the engine systems are adjusted, as a result of which the engine operation is optimized, and it becomes more responsive due to modified injection and increased power. The dynamics of the Niva car while driving also improves. 5.

Paradoxical but true. Despite the increased supply of gasoline to the working mixture, the vehicle's operating fuel consumption is reduced, which has a beneficial effect on the ecological atmosphere of the environment. Note! There are programs on sale on the market that are intentionally prepared for chip tuning of Niva cars.

What Russian doesn't like fast driving? If there is no chance of buying a car with a huge number of horses under the hood, the search begins for methods to increase the engine power of your car. It will be easier to do this with a carburetor engine, because in an injection engine the control is carried out from the control unit. You can “work magic” with a carburetor in your own garage with basic auto mechanic skills.

Instructions

1. Injection system - carburetor. A primitive method to slightly increase power is to replace the jets in your carburetor. True, using this option, you will increase not only power, but also gas mileage. 2. Another option is to replace the camshaft. In this case, you are changing the camshaft to a shaft with different cam angles and heights, which will provide a large amount and duration of valve opening.

This will change gas exchange and increase power. But there are negative results from replacing the camshaft - increased loads on the gas distribution mechanism, valves may begin to stick. To prevent this from happening, it is necessary to install sports (titanium) valve springs. The valves can break off due to a sharp lift by the installed camshaft; therefore, the valves themselves need to be replaced with reinforced ones. 3.

A more labor-intensive option is boring the cylinder head (cylinder head). When boring the cylinder head, the diameter of the intake and exhaust channels increases, and valves with huge diameter plates are installed. The disadvantage of this method is major wear and tear on the gas distribution mechanism. 4. Boring the cylinder block. By choosing this method, you increase the engine displacement and, consequently, power.

https://www.youtube.com/watch?v=ytdevru

The disadvantage of this method is the risk of damage to the engine cooling system. If the cylinder block is made of light alloy metal, there is a possibility of the engine overheating. 5. Nitrous oxide N20. This forcing option is the most unreliable and quite precious. Nitrous oxide is supplied to the cylinders with fuel.

It is a well-known recreational gas used for anesthesia. The thesis is that under the influence of high temperature, nitrous oxide breaks down and an additional proportion of oxygen is obtained in the cylinders, which increases detonation. With this method, there is a risk of burning out the piston rings and the pistons themselves.

Gasoline with a high octane number is produced by two methods: using difficult technological operations, which increases the cost, and by adding anti-knock additives. From 76 gasoline it is absolutely possible to obtain 92, from which fuel with an octane number of 95 is easily made.

You will need

• – anti-knock substance.

Instructions

1. Methyl tert-butyl ether, which has the form of a colorless, flammable liquid with a specific odor, is especially widely used. It is characterized by low toxicity, but has a high octane number. When adding 15% ether, the octane number increases by 12 units. Many gasolines are produced using just such an ether class additive.

MTBE is highly volatile, which makes gasoline easier to evaporate in hot weather. 2. To increase the octane number, it is also possible to add alcohol to the fuel. The addition of 10% ethyl alcohol to the entire liquid allows you to change AI-92 to AI-95, while reducing the toxicity of the exhaust gas. However, you should be more careful when using alcohols, because...

they can cause the formation of special vapor locks that disrupt the operation of the vehicle’s fuel system. Moreover, ethyl alcohol is highly soluble in water, which requires the use of special fuel storage conditions and monitoring of the alcohol content. If the storage data is not observed, this may cause water to appear in gasoline, which leads to increased fuel consumption and the appearance of ice jams in the fuel system in winter. 3.

One of the most effective anti-knock agents is tetraethyl lead, which looks like a colorless liquid and has a boiling point of about 200 degrees. It is inexpensive and effective - at a concentration of 0.01% it is possible to increase the octane number by 3 points. Tetraethyl lead must certainly be mixed with another substance that will ensure the removal of lead oxides from the combustion chamber, which are deposited on the valves and pistons of the fuel system.

However, when combined with ethyl bromide or dibropropane, the substance forms leaded gasoline, which is extremely toxic. Inhaling the fumes of such gasoline causes the accumulation of lead in the body and is the cause of multiple sclerosis. Note! High-octane fuel ensures more stable and economical engine operation, reducing the number of harmful emissions into the atmosphere.

Tip 5: How to increase octane number

Gasoline with a high octane number is produced by two methods: using difficult technological operations, which increases the cost, and by adding anti-knock additives. From 76 gasoline it is absolutely possible to obtain 92, from which fuel with an octane number of 95 is easily made.

MTBE is highly volatile, which makes gasoline easier to evaporate in hot weather.

Refinement of the gas distribution mechanism

The timing also largely determines the power and other technical features of the engine. Tuning the gas distribution mechanism consists of increasing the diameter of the valves followed by sealing. As practice shows, such modernization allows increasing power by almost 10%.

In many cases, when improving the engine part in question, the pushrod is replaced. Its improvement consists in increasing the intake and exhaust tappets, which can significantly increase the engine power rating.

The modifications under consideration make it possible to improve the smoothness of the ride, reduce wear of parts, and significantly increase the power rating. Of course, there are other methods of engine modification that can achieve attractive values. An example is the case of modifying the oil pump, which also makes it possible to make the engine more torquey.

Tip 7: How to increase the octane number of gasoline

There are two ways to increase the octane number of gasoline: simple - by adding anti-knock agents (special additives) to it, and difficult - using a special technology that will increase the cost of the product. It is possible to “make” AI-92 from AI-76 gasoline, and AI-95 from AI-92. However, this also has its negative side. Low-quality fuel at unknown gas stations, where the octane number is unnaturally increased, leads to serious and expensive car damage.

You will need

Instructions

1. Add MTBE (methyl tertiary butyl ether), which is a flammable colorless liquid with a specific odor, to the gasoline. This is one of the means now especially used to increase the octane level. MTBE has a high octane number and is non-toxic. When adding 10-15 percent to gasoline, the increase will be approximately 6-12 units. Many high-octane gasolines are produced using this or a similar ether-class additive. The disadvantage of MTBE is its high volatility, because in hot weather it can evaporate from gasoline.

2. Add alcohols (ethyl and methyl) to gasoline. Say, a 10 percent addition of ethyl alcohol to AI-92 increases the octane number to approximately 95 units. In addition, the toxicity of exhaust gases is reduced. But the use of alcohols leads to an increase in intense vapor pressure. This may contribute to the formation of vapor locks in the fuel system pipeline. In addition, an important task is the excellent solubility in water and hygroscopicity of ethyl alcohol. This requires special storage conditions for the mixture and periodic monitoring of the contents of the alcohol component. If this is not observed, water may appear in gasoline, and this leads to increased fuel consumption, poor combustion, and if its percentage is high, ice jams may appear in winter.

3. Add tetraethyl lead Pb(C2H5)4. TES is considered one of the best anti-knock agents. It is an oily, colorless liquid with a boiling point of approximately 200°C. The use of TES as an anti-knock agent began in 1921, and today it is one of the most effective and inexpensive means of concentration 0.05%. It gives the chance to increase the octane number of gasoline to 15-17 points. Tetraethyl lead is not added in its pure form, since during combustion it forms carbon deposits - lead oxide, which is deposited on pistons, valves and other parts. To remove it from the combustion chamber, ethyl bromide, dibromopropane, and dibromoethane should be used. When burned, they form volatile compounds with lead, which are easily removed from the combustion chamber. A mixture of thermal power plants with these components and a special dye is called ethyl liquid, gasoline with such components is called leaded. Today, the production of leaded gasoline is prohibited because it has a high degree of toxicity. Lead, accumulating in the body, causes multiple sclerosis because it is poisonous. Leaded gasoline is prohibited for use in vehicles equipped with a catalytic exhaust gas converter. They are damaged when the engine is running after a few hours. Antiknock agents are also isooctane, neohexane, isopentane, benzene, toluene, and acetone.

We will improve the exhaust system

Since the exhaust system can increase the power and efficiency of the engine, tuning the VAZ-2121 engine includes the installation of modern exhaust and intake manifolds.

With their help, the process of air supply and exhaust gas removal will be optimized, and the efficiency of the power plant will become higher. To increase engine power, it makes sense to install a resonator from the muffler. With it, exhaust gas removal improves, and the running engine acquires a beautiful bass sound.

https://www.youtube.com/watch?v=ytpolicyandsafetyru

Tuning the VAZ (Niva) engine also includes moving the muffler further to the rear axle, when almost the entire exhaust system is dismantled. In this case, the resonator can be installed from any car, for example, from a Moskvich.

Tuning options

When refining a Niva engine, a new crankshaft, cylinders and piston system are most often installed. As a result, the car receives excellent speed characteristics and cross-country ability.

There are two types of Niva engine tuning. The first includes chip tuning, and the second includes mechanical modification of the element. Chip tuning includes software upgrades, and is carried out only on new, fuel-injected SUVs. It includes flashing the control unit settings. It is performed by specialists quite quickly - within half an hour, but requires knowledge of software and additional electronic equipment.

Mechanical modifications are possible on any Niva, and this is the most popular type of tuning of a car’s power plant. With its help, you can significantly improve the technical characteristics of vehicles, and it is based on making some changes to the vehicle systems.

Experts' opinion

Gena. The engine can be called the real heart of the car. Many people recommend starting tuning with it, since only by improving the engine can you make the car run over bumps and fords. I will say right away that the task is not an easy one. Improving an engine can take a lot of time and effort. Therefore, you should be prepared for difficulties.

Stanislav. The Niva is a good car, even one of the best produced by the domestic auto industry. However, it has many disadvantages, among which we note the low engine power and its unstable operation. That is why, almost immediately after purchasing this car, I immediately upgraded the engine.

https://www.youtube.com/watch?v=ytaboutru

Vitaly. I decided to modify the standard Niva engine. There was a lot of work, so I decided to entrust it to professionals. Although I myself have some experience in engine repair, I did not undertake its complete modernization. As a result of the work done, the guys increased the power by 60 hp. Of course, not an impressive result, but still the traction has increased significantly.

"Niva Taiga" History and tuning of VAZ 21213

Story

Just think - the Volzhsky Automobile Plant did not make changes to the design of the VAZ 2121 Niva, released in 1977, for almost 16 years! Such an original car has justified itself. However, nothing lasts forever - in the early 90s, the Niva began to become obsolete. Therefore, it was decided to carry out some modernization of the existing car.

The first result of this modernization was the appearance of a restyled version of the Niva - VAZ 21213, which entered mass production in 1994. The car received the name “Niva Taiga” from the designers. However, it turned out to be so similar in appearance to its predecessor that car enthusiasts pretended that they had not noticed the appearance of the new model, continuing to call the “Taiga” “Niva”.

Indeed, the external similarity between the VAZ 2121 and the VAZ 21213 is obvious - they are still the same three-door, four-seat all-terrain station wagon. But there are still differences. And with a more detailed study, they become increasingly easier to notice. Thus, the rear door was extended to the bumper, thereby reducing the loading height. The rear light block, which the Niva inherited from the VAZ 2106, was replaced with its own square one. The atmosphere inside the cabin has also changed - its comfort has increased (largely due to the installation of updated front seats), a new dashboard has appeared (borrowed from the VAZ 2108). Otherwise, the appearance of the Niva Taiga remained the same as that of the VAZ 2121.
