126 motor design features description
The Lada Priora engine is installed on a VAZ 2170 car and its modifications. In the cylinder-piston block of the 21126 engine, the cylinder walls are well honed to obtain improved internal surfaces. The 11183 cast iron crankshaft features a larger crank radius. The original toothed pulley is indexed with special number 21126.
The semi-circular profile of the teeth ensures engagement with the branded belt, which has 137 teeth of the same profile, the gas distribution mechanism. The service life of the gates timing belt is designed for 200 thousand km.
The connecting rod and piston group was developed by Federal Mogul. Engineers have created a design that weighs 30% less than the 2110. Federal Mogul piston rings are thinner. In order to reduce friction losses, the connecting rod is thinned, and its head does not touch the crankshaft. Original single use bolts are used to install the connecting rod cap. Width of new connecting rod bearings equal to 17.2 mm.
Thinner piston rings, compression upper and compression lower, have a height equal to 1.2 and 1.5 mm, respectively. Oil scraper ring made 2 mm high.
The cast-iron cylinder head 21126 - 1003011, designed for Priora 16 valves, has a platform suitable for the new timing belt tensioner. The head is molded together with the glasses of the wells for candles.
The cylinder head gasket has two metal layers, its total thickness is 0.45 mm. The design of the part provides special holes for the cylinders. The diameter of each hole is 82mm.
Catalytic converter - catolector model 11194 - 1203008 - 10(11), ensures compliance with Euro 3 toxicity standards. For Euro 4 standards - model 11194 - 1203008 - 00(01), respectively.
Changes have been made to the water pump to extend the service life - the use of bearings and seals of a different type.
Ignition system and fuel system the power unit does not differ from the VAZ 11194. Spark plugs for Priora 16 valves are equipped with individual ignition coils. Fuel rails made of stainless steel are suitable for installing branded SIEMENS or BOSCH injectors that supply fuel in accordance with certain phases.
The universal scheme of the lubrication system consists of the following components:
- Oil pump, consisting of gears.
- Steel crankcase under the cylinder block.
- Oil filter.
- Oil pressure sensor.
The electronic control system of the engine is equipped with a January 7.2 or M 7.9.7 controller.
Factors affecting the resource of the VAZ 2170
According to the manufacturer of the internal combustion engine 21126 for sixteen valves, it has a stable operation duration of 200 thousand kilometers. After a certain mileage, it is necessary to carry out overhaul. Respect for the VAZ 2170, serviceable Maintenance(TO) and timely replacement of damaged components and parts will lead to a long service life of the car.
Reasons affecting the duration of the operation of the power unit:
- Engine overheating. Elevated temperatures of a running engine negatively affect the overall life of the motor. Maintaining the operating temperature of the elements of the power unit at a constant level significantly lengthens the time of its operation.
- Fuel. The vehicle owner's manual contains detailed information about the recommended brand of gasoline. Pour fuel into the engine at Priora 16 valves of proven quality.
- Machine oils. What oil is better to fill in, its brand and how much is needed lubricant indicated in the accompanying documentation for the car. The 126 sixteen valve engine is most suitable for semi-synthetic and synthetic motor oils. Complete replacement oil should be carried out annually or after a run equal to 15 thousand kilometers.
The optimum temperature value of the working engine is 90 - 95 °C. The rules allow the operation of the power unit with a temperature reaching up to one hundred degrees, provided that the radiator fan is running. The engine temperature is below +90°С. In cold weather, more time is needed to warm up the engine to the desired mark on the device.
When servicing your VAZ 2107 car, the car owner can do the oil change with his own hands. To do this, you need to know how to drain the used lubricating fluid, which oil to pour into Priora and how much engine oil pour into the neck.
Is the valve bent
In Lada Priora cars, even in a 16-valve power unit 126, valves can often bend. The reasons for this defect lie in non-compliance with the rules of operation, in case of violation of the regulations for the replacement of the following components and parts:
- rollers;
- timing belt (timing);
- water pump.
If one of the listed components breaks down, the pistons, rendering mechanical influences on the valves, they can be bent. Design features engine - these are the reasons that the engine can bend the valves. The deformation of the valves makes it necessary to overhaul the Priora engine.
To avoid this defect, the car owner needs to timely check the timing elements. Of particular importance is the belt, which is subject to a thorough examination after 50 thousand kilometers. The check excludes the following faults:
- cracks;
- bundles;
- breaks.
The timing rollers and pump 126 should also be inspected, because. the motor bends the valves even if they malfunction.
Signs of worn timing belt and other timing components are vibrations and an unpleasant rattle in engine compartment. In this case, it is urgent to repair or replace the broken elements in order to avoid deformation of the engine valves.
Why does the engine troit
Of the frequently occurring breakdowns of this power unit, defects such as unstable operation and motor tripling are noted. Such failures occur due to the appearance of malfunctions in the components and parts of the engine:
- fuel pressure reduction;
- defects in the elements of the gas distribution mechanism;
- malfunctions of sensors;
- violation of tightness in hoses;
- faulty throttle valve.
The power of the power unit is reduced for the following reasons:
- low compression in one or more cylinders;
- burning gaskets;
- cylinder wall wear;
- erasure of piston rings;
- deformation of pistons under the influence of high temperatures.
Trouble of the engine can be eliminated by flushing the nozzles. The reasons for the unstable operation of the power unit may lie in the malfunction of the following devices:
- candles for Priora 16 valves;
- ignition coil;
- throttle valve;
- regulator idle move;
- battery;
- starter;
- ignition coil;
- gasoline pump;
- fuel filter;
- fuel pressure regulator.
Candles on Priora can be replaced independently. To do this, you need to familiarize yourself with the principles right choice and replacement of these nodes, described in special articles on the Internet.

In addition to the considered method of converting a power unit to increase dynamic performance, there are several more ways to tune a car of this model.
How much horsepower in Prior
car now Lada Priora enjoys well-deserved popularity, not only among Russians, but also in the market of other European countries. And this is not easy, because Priora has not only a nice price, but also a huge number of both external and internal features, therefore it is able to compete with many cars in its own price sector.
The history of Priora has already 7 years of successful production. Since 2007, it has been modernized many times - today Lada Priora has the following features:
There are two modifications of engines - with 8-valve and 16-valve engines, with a volume of 1.6 liters. Equipped with a manual gearbox and front-wheel drive, Lada Priora, whose horsepower is 90 liters and 98 liters, depending on the installed engine, indicates a surprisingly very fast ride.
The highest torque, which was introduced with the help of foreign production.
The environmental friendliness of the motor has increased.
LADA PRIORA priora power measurement
Review and test car Lada Priora. Taking into account all the alterations, the engine power is about 150 horses.
Priora power check in the FCC. 145.2 HP
Add me to friends! https://vk.com/id292199998 For cooperation! [email protected] Shafts approx.
The power of the updated version of the car was increased by 10%, due to this issue how much horsepower is in prior, has become more relevant, because an increase in power means an increase in the amount of horsepower. The engine size has also become larger in new modification Frets, by increasing the piston stroke, while the cylinder diameter remained the same.
Power units such as Lada Priora – horsepower in principle, they have practically gone out of use, but in Russia they are still common where internal combustion engines are used.
Since horsepower is often calculated after upgrading a car, it takes place in kilowatt / hours and they are indicated in the vehicle’s data sheet, find out How many horsepower in Lada Priora it is possible, according to this translation: 1 l / s equals 735.5 W or 0.735 kW.
The developers also upgraded the cooling system of the unit and equipped the drive with an automatic tensioner. They try to reduce mechanical losses, thereby reducing noise and vibration.
No matter how hard the manufacturers try, malfunctions can be in a car of any brand, the most frequent problems Lada Priora engine:
1) Power reduction
2) Black exhaust
3) Difficulty starting the engine
4) Too high fuel consumption
The above malfunctions can be easily identified by the color of the exhaust: blue smoke can mean that the cylinder and piston parts are significantly worn out; White smoke means that coolant has entered the combustion chamber, and black smoke indicates a malfunction of the control system.
Among motorists, the Lada Priora is considered the most controversial model of all the cars in the VAZ line. It was based on the platform of the 84 model. This machine became a replacement for the VAZ-2110. The car turned out to be much more interesting than its predecessor. What engine is on the Priore? Let's see.
This car can easily compete with inexpensive foreign cars. It has normal comfort, as well as good dynamics and reliability. Compared with previous models, designers have managed to significantly improve all indicators of handling.
The car received a lot of unfounded criticism, especially the old 8-valve Priora engine was to blame. However, after the power units for them were replaced with new ones, they simply amazed motorists. If you look at it, it's almost impossible to see much of a difference. But consumption decreased by 1 liter, power increased. The engine began to work much quieter than its ancestor. This is felt by both the driver and passengers. Just look at the photo of the engine to understand everything.
The unit runs smoothly at all speeds. If the "ten" required getting used to, then here you can ride, almost without straining. This was achieved with the improvement of the design.
The Priora engine has a capacity of 98 hp. With. and a volume of 1.6 liters. This motor complies with Euro 3 requirements. Let's look at it in more detail.
Design
The power unit of Lada Priora cars provides torque, which is transmitted to the drives and wheels using the transmission system. This ensures the movement of the car.
VAZ-21126 units are installed on cars. These motors are designed on the basis of VAZ-2112 engines. Engineers increased the engine displacement to 1.6 liters, and also lengthened the piston stroke. The cylinder diameter remained the same.
Engine characteristic
Before us is a 1.6-liter sixteen-valve injection unit with Euro 3 standards. It is equipped with a distributed injection system controlled by an ECU. Cylinders are in-line. The working volume of the engine is 1596 cubic meters. see Maximum power - 72 kW. The torque that the engine produces is 145 Nm. 95 gasoline is supposed to be used as fuel. Fuel consumption on this unit is equal to 7.2 liters according to the passport. The maximum speed that Priora is capable of with a new motor is 183 km / h. The car can accelerate to 100 km in 11.5 seconds. Despite the fact that you can put such an engine on the Priora, the price of which is about 35-100 thousand rubles, in almost any garage, it is definitely worth the money.
- materials
This assembly is made of specially developed cast iron alloys with high strength characteristics, which made it possible to obtain the necessary indicators of rigidity and strength. The channels for the circulation of the coolant now run along the entire height of the block. This made it possible to significantly improve cooling and also reduced the deformation of the cylinder block due to overheating, which did not differ in uniformity. The channels for the passage of coolant are located at the top of the cylinder head.
Below you can find five supports for the crankshaft. Covers are fastened with bolted connections. Inserts are installed in bearing supports. They are made of a special steel-aluminum alloy. They are used as bearings for the crankshaft. The middle support has special grooves. In the latter, persistent half rings are mounted. They are designed to securely fix the shaft. This way you can avoid moving the part along the axis.
Compared to the 2112, this unit is slightly taller. You can see a photo of the engine.
Crankshaft and its features
This assembly is made by casting from special alloys of high-strength cast iron alloys. In order for the part to be lubricated along with the connecting rod bearings, it has technological lubrication holes or channels. They are closed with caps.
To reduce vibration during operation, the engineers used eight counterweights. They are located on the crankshaft. The radius of the crank mechanism is now (in comparison with previous modifications) increased by 2.3 mm.
A pump is installed in front of the device for oil system as well as for the timing belt. Also, the Priora engine is equipped with a generator drive with a damper. At the rear is a cast iron flywheel. It has a special gear rim made of steel.
connecting rods
These nodes are made by forging steel. They have caps on the heads underneath. They are produced by tearing off solid connecting rods. In this way, higher accuracy characteristics can be achieved. In the lower part of the connecting rod, liners with thin walls are mounted.
Pistons
The Lada Priora engine has many features. In particular, it is equipped with pistons made of special aluminum. Each of them has special rings in the amount of three pieces. The top two on each piston are compression rings, and the third, bottom, is oil scraper.
The bottom has a flat shape, as well as four recesses for valves. At the same time, the recesses on the pistons are slightly increased compared to the previous modification of the engine. The piston group is cooled with oil. To do this, the engineers provided for the presence of nozzles in the main bearing supports. These are tubes with balls on springs. When the engine is running, these parts allow you to create a supply of oil to the piston.
cylinder head
The cylinder head is mounted on top, on This part of the engine is made by casting from special aluminum alloys. Its lower part has channels for the circulation of the coolant. Top mounted camshafts. One is used for intake valves, the other for exhaust valves. The cylinder head on this engine is significantly different from the previous modification. Larger area flanges are used here, as well as the walls of candle wells. The latter are now integral with the head.
camshafts
These nodes are mounted on supports that are located at the top of the cylinder head. They are made from high strength cast iron. The Priory engine is equipped with hydraulic pushers, which, in automatic mode adjust valve clearances. The motor for the entire period of operation will not require its owner to adjust the clearances.
The unit has four valves per cylinder. The guide bushings and seats are firmly pressed into the cylinder head. Also, the first parts are equipped with retaining rings. The guides are provided with caps for removing oil.
Lubrication system
This node is made in the form of a combined system. Oil is supplied both by spraying and under pressure.
Engine cooling system
It is presented in the form of a cooling jacket in the engine block and cylinder head. As well as in many other models from AvtoVAZ, there are other nodes in the SOD. This is a radiator, a coolant pump, and an expansion tank.
Food
This part of the engine design is also no different. It, like previous models, consists of standard parts. The only difference is in the fuel rail. Now it has the shape of a pipe without backflow. It is made of stainless steel, not aluminum, as before.
The injectors have also been changed. Now they are slightly smaller. The pressure regulator has also changed. AT new version it is located in the fuel pump housing. The throttle assembly does not have a hole that in past designs connected the air supply hose to the intake module.
Ignition
This system is presented from individual coils on the cylinder head and candles. All this economy is controlled by the ECU. This innovation made it possible to abandon the high-voltage part, as well as to make the system more reliable in operation.
Additional information about the engine
"Priora" (16 valves) was designed and developed together with the VAZ-11194 unit. Although these models had a difference in volume, in most of the designs and main components, the two motors are the same. One of the main tasks that the developers faced was to achieve an increased resource. The engineers took the VAZ-21124 as the basis. Thus, the use of new technologies and solutions has allowed designers to significantly increase the period of work.
Lubrication question
Many motorists who have just become owners of this car do not know how to lubricate the engine. "Lada Priora" can work on various types lubricants.
Today there is big choice materials for these motors. The main point here is to prevent mixing oils for the transmission and for the engine. In "Prior" these fluids work as efficiently as possible, and the consumption will be reduced to almost the minimum.
For each specific power unit, the consumption will be different. However, even if you know what to pour into the engine, it is still better to consider the opinions of experienced motorists.
Before choosing an oil, it is better to first evaluate the color and density. lubricating fluid. It is important that the density matches your motor. Often the characteristic of the engine includes just such information.
You can check the quality of the oil right at home. To do this, you need a piece of toilet paper or a napkin. You need to drop a little on a piece of paper or napkin. So, if the oil is absorbed quickly, then it is perfect.
Viscosity in winter and summer
So, what kind of oil to fill in a VAZ Priora car? You can pour into the engine of this machine different types liquids. But first things first.
Many people ask how to change lubricants in different seasons. As experienced drivers say, you need to select fluids according to the characteristics that are indicated in the service book for the car.
In winter, in order for your Priora to start up even in the most severe frosts, buy goods with the OW index in the title. If the frosts are small, then 15w-40 is ideal for a normal winter.
In the summer, you can get by with absolutely any oil. It is important to make the replacement on time. This way you can save a lot of money on repairs. Especially it concerns automatic boxes gears.
How much does a motor cost
Often they are interested in how much it costs to put the engine on the Priora. The price for a 16-valve unit will be from 35 to 100 thousand rubles, depending on the technical condition.
rebirth
AvtoVAZ recently announced the start of sales updated versions car data. It will be a 1.8-liter engine. The small-scale production of these units is carried out by the company "Super-Auto"
Previously, such machines have already been manufactured. But now it will be perfect new engine. "Priora", namely her power point, will be named 21128. The torque will be 145 Nm, and what the power will be, while the manufacturer keeps it secret. But it is already known that the dynamics have slightly improved on the new engine, and fuel consumption has remained the same.
Engine VAZ 21126 1.6 liters. injection in-line 4-cylinder with overhead camshafts, gas distribution mechanism has a belt drive. The resource of the motor 21126 prior, according to the manufacturer's data, is 200 thousand km, how much the engine runs in practice ... how lucky, on average, it is about the same.
The car received a lot of unfounded criticism, especially the old 8-valve Priora engine was to blame. However, after the power units for them were replaced with new ones, they simply amazed motorists. If you look at the technical specifications, it is almost impossible to see much difference. But consumption decreased by 1 liter, power increased. The engine began to work much quieter than its ancestor. This is felt by both the driver and passengers. Just look at the photo of the engine to understand everything.

The 21126 engine is a continuation of the VAZ 21124 tenth engine, but with a 39% lighter SHPG manufactured by Federal Mogul, the valve holes have become smaller, another timing belt with an automatic tensioner, thanks to which the problem of tightening the belt on the 124 block has been solved. The Prior engine block itself has also undergone minor changes, such as better surface treatment, cylinder honing is now carried out in accordance with the more stringent requirements of Federal Mogul. On the same block above the clutch housing there is a place with the prior engine number, to see it, you need to remove it air filter and arm yourself with a small mirror.
There is a lightweight version of this engine - the viburnum engine 1.4 VAZ 11194, as well as a sports forced version - the VAZ-21126-77 engine (120 hp). This is the result of the refinement of the VAZ-21126 engine. A distinctive feature of the motor in power, which is added after 3000 rpm. The rest of the engines are almost the same. When the timing belt breaks, the valve will also bend. Among the shortcomings of this power unit, it is worth noting unstable operation, loss of power, timing belt. The reasons for unstable operation and refusal to start may be problems with fuel pressure, malfunction of the timing, malfunction of sensors, air leakage through hoses, malfunction of the throttle. Loss of power can be associated with low compression in the cylinders due to burnt gaskets, wear of cylinders, piston rings, burnt pistons. A significant drawback is that the priors 21126 engine bends the valves. The solution to the problem is to replace the pistons with plug-in ones. Nevertheless, the prior motor is currently one of the most advanced domestic engines, perhaps worse reliability than the 124th, but the motor is also very good and powerful enough for comfortable movement in the city. In 2013, a modernized version of this engine was released, marking the new priory engine VAZ 21127. In 2015, the production of a sports NFR engine called 21126-81 began, which used the base 21126. And since 2016, cars with 1.8 liter engines are available, which was also used by 126 th block.
The most basic malfunctions of the 126 motor
Let's move on to malfunctions and shortcomings, what to do if the prior engine is troiting, sometimes flushing the nozzles solves the problem, maybe it's the spark plugs or the ignition coil, but the usual thing in this case is to measure the compression in order to eliminate the problem of valve burnout. But the most cheap option go to the service for diagnostics.
Another common problem is when the engine speed of the prior 21126 floats and the engine runs unevenly, a common disease of the VAZ sixteen valves, your DMRV is dead! Not dead? Then clean throttle valve, there is a possibility that it is asking for a replacement of the TPS (throttle position sensor), perhaps the IAC (idle speed controller) has arrived. What to do if the car does not warm up to operating temperature, there may be a problem in the thermostat or too very coldy, then you have to collective farm cardboard on the grille. Regarding overheating and warming up, do I need to warm up the engine? Answer: it definitely won’t get worse, warm up for 2-3 minutes and everything will be fine. Let's get back to the jambs and problems of motors, your prior engine does not start, the problem may be in the battery, starter, ignition coil, spark plugs, fuel pump, fuel filter or fuel pressure regulator. The next problem is that the priors engine makes noise and knocks, this occurs on all Lada engines. The problem is in the hydraulic compensators, the connecting rod and main bearings (this is already serious) or the pistons themselves can knock. You feel a vibration in the prior's engine, it's the high-voltage wires or the IAC, maybe the nozzles are dirty.
Engine tuning Priors 21126 1.6 16V
Chip tuning engine Priora As a pampering, you can play around with sports firmware, but there will be no obvious improvement, how to properly raise the power, see below.Tuning motor Priors for the city
There are legends that the Priora engine produces 105, 110 and even 120 hp, and the power was underestimated to reduce the tax, various measurements were even made in which the car produced similar power ... what everyone decides to believe for himself, let's dwell on the indicators declared by the manufacturer. So, how to increase the power of the priors engine, how to charge it without resorting to anything special, for a small increase, you need to let the motor breathe freely. We put the receiver, exhaust 4-2-1, throttle 54-56 mm, we get about 120 hp, which is quite nothing for the city.
Forcing the priors engine will not be complete without sports camshafts, for example, STI-3 rollers with the above configuration will provide about 140 hp. and it will be fast, great city motor. The refinement of the priors engine goes further, sawn cylinder head, Stolnikov shafts 9.15 316, light valves, 440cc nozzles and your car easily produces more than 150-160 hp.
Compressor on Priora
An alternative method of obtaining such power is to install a compressor, for example, the most popular option is the Auto Turbo Kit based on PK-23-1, this compressor is easily installed on a 16-valve Priory engine, but with a reduction in compression ratio. Then there are 3 options: 1 . The most popular one is to lower the SJ with a gasket from a dvenashka, put this compressor, exhaust on 51 pipes, Bosch 107 injectors, install and go to the track to watch how the car knocks. And the car doesn’t really bring down … then run to sell the compressor, write that Autoturbo doesn’t go and all that … not our option. 2 . We lower the coolant by installing a thick cylinder head gasket from 2112, for a St. Petersburg supercharger at a pressure of 0.5 bar this will be enough, we select the optimal narrow-phase shafts (Nuzhdin 8.8 or similar), exhaust pipe 51, Volga BOSCH 107 injectors, receiver and throttle valve standard. To completely squeeze out the configuration, we give the cylinder head for cutting the channels, install enlarged light valves, this is not expensive and will give additional power throughout the entire range. The whole thing needs to be set up online! We will get an excellent motor that rolls in any (!) range with a power of more than 150-160hp. 3 . We lower the SJ by replacing the piston with a tuning one for a turbo, you can put a proven Nivovsky piston with a puddle for a turbo on 2110 connecting rods, you can put a more efficient compressor on such a config, for example, Mercedes, blow 1-1.5 bar with a power far beyond 200+ hp . and blame like the devil!) The advantage of the config is the ability to install a turbine on it in the future and blow out at least all 300+ hp. if the piston does not shatter to hell))Engine boring Priors or how to increase volume
Let's start with how not to increase the volume, an example would be the well-known VAZ 21128 engine, don't do it)). One of the most simple options increase the volume install a motor kit, for example, STI, we choose it for our 197.1 mm block, but do not forget about the jambs of the 128th motor, do not rush to install a long-stroke knee. You can go the other way and buy a high block 199.5 mm prior, 80 mm crankshaft, bore cylinders up to 84 mm and a connecting rod 135.1 mm pin 19 mm, this will give a total of 1.8 volume and without damage to R / S, the motor can be free to twist, put evil shafts and squeeze out more power than the usual 1.6l. To spin your motor even more, you can build up a standard block with a plate, how to do it, how it spins on a 4-throttle intake and wide shafts.
To increase the stability of the engine and the response of the gas pedal, put 4 throttles on the intake. The bottom line is that each cylinder receives its own throttle valve and due to this, the resonant oscillations of the air between the cylinders disappear. We have a more stable operation of the motor from the bottom to the top. The most popular method is to install a 4-throttle inlet from Toyota Levin on a VAZ. It is necessary to purchase: the assembly itself, make a manifold adapter and pipes, in addition to this, you need a nulevik filter, Bosch 360cc injectors, DBP (absolute pressure sensor), fuel pressure regulator, wide shafts (phase over 300), sawing cylinder head channels 40/35, light valves, Opel springs, hard pushers, spider exhaust 4-2-1 on 51 pipes, and preferably on 63 pipes. There are ready-made 4-throttle intake kits on sale that are quite suitable for use. With the correct prior configuration, the motor produces about 180-200 hp. and more. To go beyond 200 hp on a VAZ atmosphere, you need to take shafts like STI Sport 8 and spin it at 10,000 rpm, your engine will give out more than 220-230 hp. and it will be quite a hell of a drag cramp. The disadvantages of chokes include a reduction in engine life, and this is not surprising, because even city engines on pipes spin at more than 8000-9000 rpm or more, so you cannot avoid constant breakdowns and repairs of the 21126 prior engine.
There are many methods for building a turbo prior, let's see the urban version, as more adapted to operation. Such options are most often built on a TD04L turbine, a field with grooved pistons, ideally Stolnikov 8.9 shafts can be USA 9.12 or similar, 440cc nozzles, 128 receiver, 56 damper, exhaust on a 63 mm pipe. All this junk will give more than 250 hp, and we'll watch the video how it will go. And what about the serious valilov? For the construction of such motors, we leave the bottom the same on a reinforced block, a sawn head, Nuzhdin 9.6 shafts or similar, hard studs from 8 valves, a pump of more than 300 l / h, nozzles plus or minus 800cc, we put a TD05 turbine, direct-flow exhaust on 63 pipes. This set of iron will be able to inflate 400-420 hp priors into your motor, for a light car weighing a little more than a ton, this is enough to take off into space)
