Many owners of domestic cars are thinking about modifying their "iron horses." Given that more modern models are equipped with injectors, it is available to install a 16-valve power unit on them. The Niva-Chevrolet with the engine from the Priora is very popular, as well as the classic VAZ models with the same modified engine.
Features of the installation of the power unit
Engine installation from Priora to Niva-Chevrolet or VAZ 2107 will take one or two days from a specialist. But first, it is worthwhile to devote a lot of time and money to the preparatory work. First you need to buy the engine itself. If you purchased a used motor, you need to sort it out, which will allow to extend the working life in the future.
Another advantage of disassembling and revising the unit is the ease of installation of the transition elements and the cylinder block, especially if the parts for the Chevrolet Niva with the Priora engine were made by hand. Manipulation is best done with a screwed oil pan, which will also require refinement.
Start of preparatory work
Begin preparations for installation by dismantling the flywheel of the new power unit. Its teeth will be incorrectly located in relation to a gear wheel of a starter. It is necessary to purchase a suitable crown and put it on the flywheel.
It should be borne in mind that the Chevrolet Niva with the engine from Priora is modified only in the motor part. The gearbox remains unchanged, so you should take care of a reliable and proper connection of these two blocks. Optimally, this operation is carried out using a special adapter plate. You can buy a finished item or make to order. An alternative to connecting the gearbox and the engine can be fixing the engine block to the gearbox directly. In this case, only three mounting bolts will be involved. Many motorists who have tested this in practice claim that the clutch is quite reliable.
Niva-Chevrolet engine powered by Priory: the main stage of preparatory work
The updated engine will be slightly extended towards the passenger compartment. For its correct installation, it is necessary to cut out a part of the partition from metal that separates the motor unit and the interior of the car. Manipulation is recommended to be carried out carefully so as not to cut out the excess part, since the processed element provides body rigidity. Alternatively, you can use a saw grinder, if you have the appropriate experience.
In the front part of the crankshaft of the newly installed motor, the installation of a support bearing will be required . VAZ-2107 and 21213 "Niva" with the engine from the "Priora" need fitting element. Any turner will help to cope with this problem, work will not take much time. Adapters with holes should be prepared on the engine mount pads.
The final stage of preparatory work
If the car under development was equipped with a carburetor system, you should install an external electric gasoline pump, a gas pedal with a cable, and a fuel filter. The discharge element from the Volga with an injector is quite suitable. You will also need to install a special adapter for the clutch unit.
If the car is equipped with an injection fuel system, then installation and connection of control electronics will not constitute special problems. When installing a VAZ-2112 or Priora engine on a Niva, you will have to spend a lot of time preparing. However, the subsequent effect and the new “heart” of the iron horse are worth all the effort.
Power Unit Installation
Having completed all the preparatory work, you can proceed with the installation of the motor. This process rarely takes more than one day from a professional repairman. Self-participation requires more time and effort.
The largest amount of work will have to be done with the alteration of the cooling and exhaust system. The old collector from the VAZ of early releases will not fit the Priorsky motor, as well as the connecting pipes, some elements of the cooling system. The parts under consideration are problematic to purchase in finished form, but they can be made to order or using gas welding.
The adjustment of the products under consideration is carried out after a new power unit with a cylinder block is mounted on the pillows. Experts recommend transferring the neck for filling oil into the motor, since it abuts against the baffle, which complicates the process of filling the mixture and setting the valve cover.
Advantages of the engine
The engine with 16 valves turned out to be very successful. Many owners put it not only on the “classics” of the VAZ, but also on new models (Niva-Chevrolet, 2109, 2114). On such cars, the installation of the power unit is greatly facilitated due to the combination and identity of most elements.
VAZ-2107 with an engine from Priors has the following advantages:
- high characteristics of the motor in terms of torque, power and fuel consumption;
- the product is created using modern technology;
- the universality of many elements and assemblies compatible with other VAZ engines allows you to install the unit on different models of cars;
- the design of the power unit from the Priors does not imply a constant adjustment of the valves and pulling up the timing chain;
- the motor is considered one of the best among domestic units.
Chevrolet Niva with an engine from Priora, the price of which depends mainly on the general condition, is more economical, without losing maneuverability and power. The unit will cost in the amount of 35 to 100 thousand rubles.
Technical characteristics of the latest modifications of the Priors motor
A common model of the motor in question is released under the index 21126. The unit has a working volume of 1.6 liters, a capacity of 98 horsepower. In 2013, a new modification was released, which is equipped with a VAZ-2107 car.
For greater clarity, below is a table with the technical data for the Priors power unit (21127).

Novelties equipped with the engine in question
Soon, the VAZ developers plan to release into serial production an updated Niva, which will be equipped with an engine from Priora. The new power unit will make it possible to significantly reduce fuel consumption, while increasing the speed indicators of the car.
Active work is underway at the plant to adapt the motor to the Niva. The car can be produced in two variations: with a unit with a capacity of 98 horsepower or a modified analogue that pulls 106 horses, has a torque of 148 Nm. In addition to the updated engine, the car in question will receive a new steering rack, subframe, improved seats, heating, the installation of an air conditioner is provided.

Owner reviews
The best recommendations can be given by the direct owners of the model in question, who have tested the car in various weather and road conditions. If you take the Chevrolet Niva with the engine from the Priors, the reviews of the owners indicate that the car has changed for the better. Among the special advantages, the following are noted:
- the power unit has a solid margin before overhaul;
- reduced fuel consumption, and quite noticeably;
- high speed characteristics and power;
- reliability of the unit;
- high engine performance.
Creating a Niva Chevrolet with an engine from Priora is easy. It will take some refinement of the cooling system, the seat for the unit. All manipulations can be performed in just a couple of days.
The minuses of the device in question include one point that some owners and specialists noticed. In case of a timing belt break, the inevitable interaction of the pistons with the valves occurs, as a result of which the latter bend. To avoid this, you can purchase special pistons with samples for valves.
Features
"Niva-Chevrolet" with the engine from the "Priors" has some features, compared with similar classic models of VAZs. Firstly, the installation of the power unit is simplified, since the location of the motor is identical. Secondly, variations were produced with almost the same engine as the Priors. In addition, a new serial version of the domestic SUV is being developed, under which the Priora motor is adapted, which is considered one of the best among our manufacturers.
Given the high resource and versatility of the engine in question, its installation is advisable for many VAZ models. Moreover, relatively modern modifications will require a minimum of improvements, and more classic options will gain new power and speed.
Total
Having studied all the characteristics of the motor, it can be noted that the Priors power unit is a reliable and well-developed engine. The use of modern technologies and new developments has allowed the creation of a reliable and high-quality site for domestic developers.
In addition, the reviews of the owners and the desire of many motorists, despite the additional costs of time and financial resources, to equip their vehicle with the Priora engine in addition to this unit testify.
