Improving performance begins with installing other spark plugs, more accurately selecting the advance angle, etc. Perform tuning yourself, “squeezing” 120 hp out of the Kalina-2 engine. – however, it will not succeed. The 120-horsepower Granta-Sport engine is built on the basis of the 21126, but has differences from it.
The engine of the Granta-Sport car is no less durable and reliable than the prototype (the 21126th engine of the second Kalina). To increase power, different camshafts are installed here (with a modified cam profile). Reducing the exhaust-intake resistance is another, and final, “mechanical” change. It was possible to achieve maximum power by changing the firmware.
The developers of Granta-Sport assure that up to 3,000 rpm, the engines “behave” the same. But driving at speeds above 3,500 cannot be called economical. We conclude: installing a Granta-Sport engine in a Kalina-2 with an automatic transmission is a low-use (but even more expensive) tuning method.
What about Kalina RC?
The rally version of the “second Kalina” uses an atmospheric engine (also based on the “26th”). It features forged pistons, which are lighter than stock cast pistons. It is unlikely that you will be able to carry out such tuning on your own. Tolerances must be “maintained” even more accurately than at the factory. What is most often “forgotten” when offering to buy tuning parts.
In addition, the engine was boosted. The compression ratio has increased, power has increased (up to 155 horsepower), however, durability has significantly decreased. The period of operation of sports cars is less than 1,000 kilometers (then the car is sent for overhaul). We will leave the choice to the consumer.

There are other tuning methods. For example, the installation of turbines, which is officially 100% prohibited.
The maximum moment of force on the Granta-Sport engine shaft is 140 N*m, “Kalina RC” is 175 N*m. All of the above suggests the following: the serial engine 21126 has potential for tuning. But the benefits of the changes are unlikely to be achieved without replacing mechanical parts (including ShPG elements).
However, a more affordable upgrade option, the so-called “chip tuning”, also makes sense. Which is true for most power units produced by VAZ. The question is what exactly needs to be achieved in the end.
Plug-inless motors again
From the latest news on Grant and AvtoVAZ engines: the plant is going to return to the so-called “contactless” engines, and the restyled Granta will be the first to try out a new line of engines.
What are we talking about? Not only service personnel (they know this thoroughly), but also many car owners are afraid of a situation where the timing belt breaks. At this moment, the pistons “meet” the valves and destructive consequences are inevitable. Up to engine overhaul. The new engines will be equipped with different pistons with a special selection at the bottom... exactly the size of the valve heads, which will avoid those very “critical consequences”. The official supplier of motors for the AvtoVAZ conveyor, Federal Mogul, has already mastered their production and improvements will affect: - 8 VAZ-11186 valves; — 16 VAZ-21126 valves; — 16 VAZ-21127 valves, — ..which are just being installed on cars of the Granta and Kalina families. According to the plant itself, the 106-horsepower VAZ-21129 engine, intended for Vesta and XRAY, should soon receive the same “free” version, but in the future, and with it the new 122-horsepower VAZ-21179 units. (volume 1.8 liters) and VAZ 2190 Sport “will cost” for now.

Based on your wishes - It is worth limiting the rise to 10mm and the “advertising” phase to 285 degrees PKV. Something like STI-3, Nuzhdin 9.65 (263), OKB Engine 37/42.
Friend, take normal shafts right away, I ride STI 7 shafts every day, phase 314vp 308vp.
1) 13tr? ... well, not 13t.u.e! Although if you try, why not buy a used one (for 5tr)?
2) How are they driving? look at the VSKh motor LADA-GRANTA-SPORT or Kalina2-SPORT. Both have such shafts. Compare the VSKh with a Priora motor of the same configuration, but with stock shafts! Or any other city priors with easy tuning.
3) Are you asking for city ones? So they are urban...easy tuning. Not a single SPORT shaft will fall into the urban category! Not a single Stolnikovsky camshaft will fall into the CITY category. Well, perhaps an exception can be made for 8.9 Stolnikov. All the other shafts of Stolnikov are FALLING NON-CITY RAMPS! You have conflicting desires (you have both the crane and the tit... there is only one road. PHASE ROTATION)
4) Everyone who sells SHAFT will write numbers (I’m talking about the phase) that are convenient for them for their marketing and economic BENEFIT. Those. They will tell you the phase so that they sell better! Or they’ll write just to write... they have to announce something (they won’t write a slogan... “don’t ask about the phase... we don’t know the phase”).
4) Everyone measures as it seems TRUE to him! True from the technical side or from the marketing side!
So I tried on the Lada-Grant shafts... taking them out of the KALINA2-SPORT engine. I am publishing what I measured... INTAKE 9.5mm phase 293.1gr (with a gap of 0mm) phase 255.9 (with a gap of 0.15mm) phase 241gr (with a gap of 1.27mm) 0.05 inches
Release 9.0mm phase 294.6g (at 0mm) phase 260g (at 0.15mm) phase 214.8g (at gap 1.27mm) 0.05in
5) Now it’s fashionable to mention the phase according to the American method... with a gap of 0.05″ Is it fashionable? Well, here’s the phase at 0.05″ And what does it give YOU? She gives quiche in her head!
Sometimes you see posts like this. “Before the valve opens at 0.1 mm, there is practically no gas flow, so the Americans measure from such and such a value). To which I will answer you... “YOU, on an 8V engine, adjust the valve clearances not to 0.25 -0.35 (gap), but tighten the valve by 0.1mm. Try measuring your compression. Try starting the engine! After this, the quiche in your head will subside.”
The phase with a gap of 0.2-0.3mm is relevant if YOU are using a shaft for a hard cup!
The phase of the beginning of the opening and the end of the closing of the valve is a value that helps determine the degrees of advance of the opening and closing of the intake and exhaust SHAFT relative to DVN and YVN/ Knowing the profile of the SHAFT and knowing the advance angle, YOU can determine the amount of overlap in metric values (mm), well, if YOU have a measuring tool in inches, then in principle it can be determined for inches too! I wrote the previous paragraph to YOU correctly, but I think that few people understood what it was... and that’s good! The point is that YOU “don’t give a damn” what phase the GRANTA-SPORT shaft has.

| Height | 1470 mm |
| Wheelbase | 2490 mm |
| Front track | 1430 mm |
| Rear track | 1420 mm |
| Turning diameter | 10.6 m |
| Clearance | 150 mm |
| Curb weight | 1140 kg |
| Full mass | 1540 kg |
| Trunk volume | 520 l |

Diagram of the manual transmission mechanism of model 2181
The image below shows the synchronizer device for the 2181 gearbox:
The number 1 shows the gear responsible for shifting the first gear. Under the numbers 2 and 3 are intermediate and blocking rings, respectively. The synchronizer clutch is located after them and is designated by the number 4. The hub of the synchronizer clutch is located under the number 5. The latch is under the number 6. And under the number 7 there is a gear responsible for switching the second speed mode.
The figure shows the switching mechanism itself:
Modifications Grants
Another undoubted and indestructible trump card of this car is its maintainability. Not only and not so much in the “technical” sense, but in the “geographical” sense. Yes, absolutely everything in this car cannot be repaired “on the knee”, since any modern car has on-board electrics and some kind of electronics. But there are so many specialized car services on the world map that no matter which way you look, you’ll find a specialist in VAZ products.
That is why, probably, among the models (and their modifications) the Grant is in the lead in its simplest design. And this is absolutely no (or almost no by today’s standards) bells and whistles, no “buggy electronics”, and the motor is the most basic and simple. This is a 1.6-liter 8-valve engine with a capacity of 87 horses, coupled with a five-speed manual 5MT, in the Standard version. With such a car you can drive into the very wilds of some Altai/Siberia/Far East and you won’t be left without help (if something happens). This configuration “is missing everything,” which is why some buyers “don’t like” the modern global auto industry. Is there only one airbag and only for the driver? Well, okay! Mechanical windows? Arranges!
But the ground clearance (even on the most “poor” 13-inch wheels) is as much as 165 mm! The trunk is almost 500 liters (480 liters, to be absolutely precise). Until recently, even the vaunted Mercedes-Benz S-Klasse could not boast of a luggage compartment of such volume.
Granta has only 3 (three) modifications: - Granta sedan, - Granta liftback, - Granta Sport versions,
...but with three engines, as well as three gearboxes, plus a flexible (and very long) list of additional options, the sales manager can offer the buyer several dozen (!) specifications for this car.
Consider for yourself: - engines: 8-valve VAZ-11186 with factory indexing, 87 hp. s., plus two 16-valve engines - VAZ-21126 with 98 hp. and one more, this is a VAZ-21127 with a capacity of 106 horses, plus two boosted ones for the Sport version; — three gearboxes: 5-speed manual and 2 (two) automatic transmissions for 4 and 5 gears. Now start putting together a mix from what was presented, as well as from a multi-page additional list of options for active and passive safety, comfort, media and entertainment, so you get an “unmeasured” list of configurations that allows the seller not to let the buyer bird out of his net. However, why “from the networks”? Sometimes there are even queues for the products of the Tolyatti automobile plant, and, moreover, they are completely voluntary. Other buyers are ready to wait for several weeks or months for the required equipment or to independently go to another region/city to get it, sometimes hundreds of kilometers from their own home.
From practical experience
Since this car still belongs to the economy segment of the global auto industry, the buyer should be prepared for crickets, squeaks from the sedan and rattling of the shelf that covers the lift-up luggage compartment. If we take all these squeaks and crickets and the generally “traditionally Russian” build quality of the interior, “as the norm”, car owners have practically no special complaints about the body of this car. (the body) is quite strong, well welded and will compete with other cheap foreign cars.
The only recommendation is that if you happen to take a close look at a used Granta, get high-quality diagnostics at a car service center. He got into a car accident? It is difficult to hide traces of body repair from a competent craftsman, and the body is actually the main, supporting, and most importantly, the most expensive part of any car. The exception may be high-performance versions of engines in the luxury and sports car segment, where the price of the engine is sometimes significantly higher than the price of the rest of the car, but this is certainly not the case with the Grant. Here the body is “more important” than the rest of the car.
Body features and parameters
Among car enthusiasts, there is a category whose representatives, when first getting acquainted with a car, tend to pay attention to the spaciousness of the model, and subsequently to the speed capabilities. Note that the overall parameters of the LADA Granta Sport allow for the transportation of medium-sized standard cargo, because the volume of the luggage compartment is 520 liters.
Body technical characteristics are slightly superior to those present in the “rival sister” Kalina Sport, but they are not capable of having a significant impact on increasing the degree of comfort in the cabin.
- the length of the car “grew” to 428 cm;
- width was 170 cm;
- height is characterized by 147 cm;
- note that the front axle track is 143 cm, and the rear axle track is only 1 cm narrower (i.e. 142 cm);
- base – 249 cm.
Comparison of gearbox models 2180 and 2181
In fact, the difference in these models is significant:
- For the functionality of the second model, a cable developed by Atsumitec is used. The vibration level of the second model is lower due to the cable structure;
- special synchronizers are installed in first and second gears to increase service life;
- since the diameter of the clutch of model 2181 is increased by 21.5 centimeters, a different crankcase is installed in the gearbox, and the starter is placed not along the box, but along the engine;
- the speed selection mechanism is completely new, developed by Schaeffler;
- shifting gears in cold weather is much easier, and the level of vibration on the switch is much less;
- The design of the gearbox provides for a lock in case of accidental switching to reverse gear;
- as mentioned above, the oil volume was reduced from 3.10 to 2.25 liters;
- Semi-synthetics are poured into the new gearbox, and not, as before, simple mineral water.

Grant Sport engine life: 1. According to the plant – 200 thousand km 2. In practice – 200 thousand km
TUNING Potential – 400+ hp. Without loss of resource - n.d.
Valve overlap
Valve overlap is the moment when the intake valve and exhaust valve are simultaneously open, that is, the exhaust valve has not yet closed, but the intake valve has already opened. The piston is at TDC at this moment. The simultaneous opening of the valves is necessary for the so-called cylinder purging, when the exhaust gases carry the working mixture with them through the intake valve. (by the way, a tuned exhaust manifold or “spider” can help us here) The amount of overlap is expressed in mm (in a standard timing belt, the overlap is almost 0)
Technical specifications in numbers
With 118 hp engine Mechanics
Stiffer shock absorbers and larger front and rear disc brakes are installed. R16 Yokohama tires and forged aluminum wheels, thanks to this, the braking distance is 4 meters shorter than the regular Granta. Gearbox with cable drive and short gears with a 4.3 main pair. And of course, the 1.6-liter engine produces 118 hp; the camshafts have been replaced with sports ones, thanks to which the torque increases to 156 Nm at 4900 rpm.
Safety in the car is ensured by ABS with Brake Assist, ESP, front airbags, daytime running lights and Isofix child seat mounts. In the crash test of the AutoReview Grant magazine, the sedan scored 2 stars out of 5.

The first of September became not only a day of knowledge, but also the day when AvtoVAZ raised the price tags for all its Lada Vesta models except for the maximum Exclusive configuration. Cars have risen in price by 9,000 rubles.
The time has come - the Lada Vesta SW Cross impresses with its thoughtfulness, ergonomics and attention to detail, especially in the luggage compartment. As mentioned, the Lada Vesta Cross in the new 2022 body immediately greets us with attention to detail, it all starts with the fifth door lock - there is no cylinder on it, but only a rubberized, convenient button, which is located above the license plate.

Engine
The larger the engine capacity, the more powerful the car, and, as a rule, the larger it is. There is no point in installing a small-capacity engine on a large car, the engine simply cannot cope with its weight, and the opposite is also pointless - installing a large engine in a light car. Therefore, manufacturers are trying to select a motor. to the price of the car. The more expensive and prestigious the model, the larger the engine capacity and the more powerful it is. Budget versions rarely boast a cubic capacity of more than two liters.
Engine displacement is expressed in cubic centimeters or liters. Whichever is more convenient for you.
The engine capacity of the Lada Granta Sport is 1.6 liters.
Engine power of Lada Granta Sport is from 106 to 118 hp.
"Bite" electric power steering and sport are incompatible
Power steering is another reason for improvement. It is electric and on our Lada Granta Sport it was of domestic production. Whatever the speed, it is almost impossible to find zero. On a track or on a circuit there are no complaints about it; with constant shifting, zero is simply not needed, but when driving in the city or on the highway, you want more confidence in the car.
The thoughtful “steering wheel” compromises the car in the city and on the highway.
Without a clear steering wheel, the driver is constantly in tension, doubting whether the car is going straight, the steering wheel has to be squeezed more than usual, and on a long journey this becomes tiring. So the ride is not relaxed, but truly sporty, even when you don’t ask this from the car. Quite a bit - 150-200 km along the highway, and you already want to get out from behind the wheel and take a break. It's too early for a modern car.
There are no complaints about the brakes. The rear spring cups have been raised relative to stock to accommodate 16-inch wheels.
Benefits of using modified camshafts
Installing a tuning shaft will help, by reconfiguring the valves, supply the required amount of combustible mixture to the internal combustion engine. The modified cams of the sports shaft are characterized by smooth profiles. All this allows the gas distribution mechanism to operate more reliably.
A distinctive feature of sports shafts can be considered the ability to push back the detonation limit, especially when working at lower crankshaft frequencies. Currently, you can find sports camshafts on VAZs, which are used for driving on different types of roads.
In particular, they are divided as follows:
- Instant low camshaft, which behaves best when driving on city highways;
- Universal type, intended for use of the car both in the city and on the highway;
- A riding shaft that performs best when traveling on country roads.
If you select a camshaft for an internal combustion engine with the possibility of lower valve lift, this will allow you to achieve good results at lower crankshaft frequencies. Choosing a camshaft with a higher cam lift will help increase engine performance at higher frequencies. The shafts currently produced make it possible to change the indicators of both torque and power of the power unit either in the area of lower or higher speeds.
"Lada Granta Sport" - wheel sizes and parameters
Car manufacturers were sensitive to the creation of original parts. The new Granta Sport wheels meet high quality requirements. New technologies, more durable materials are used, and there is complete conformity of dimensions for both new cars and early models.
Stock
The basic version is equipped with 16-inch silver-colored alloy wheels, which are treated with a special protective coating to avoid material corrosion and scratches from mechanical impact. The cost of original ones averages 14 thousand rubles. Knowing the article number (21905310101577), it’s easy to find suitable ones. An inexpensive alternative is to install stamps.
Basic equipment "Lada Granta Sport"
Characteristics of Granta Sport wheels for R16 tires from the factory:
- width – 195 mm;
- profile – 50%;
- radius - 16 inches.
These are installed by the manufacturer on all versions of the car (2016, 2022 and 2022).
Acceptable
If the owner is interested in a special style, then it is worth choosing wheels from third-party brands that supply wheels for the Lada Granta. Here everything is limited only by your imagination, the amount available and the size of the wheels. For Lada Granta Sport, wheels with a diameter of 15-17 inches are suitable, corresponding to DIA, PCD and ET. There are many options for tire width and profile. It is possible to put wheels on R14 tires, but the Granta looks unaesthetic on them. Therefore, if you need a spectacular appearance of the car, then you should not install wheels with a diameter of 14 inches.
Painting the part in a different color will also help make the car stand out on the road.
Sporty on the outside and no less sporty on the inside
The gearshift lever and steering wheel are now covered with very high-quality leatherette, a seven-inch touch (!) display has appeared on the console, and the front windows are electric “already in the base.” By the way, the 2022 Lada Granta Sport is comparable in cost to a “non-sport” car, but in the “Lux” specification. However, even in the previous generation, the Granta Sport version was never cheap.
Lada Granta Sport 2022 – interior/front
Today's sports "civilian" Grant has a 1.6-liter engine, boosted to 120 horses and 160 Nm, against the "former" 145. This power unit was designed on the basis of a serial engine with the VAZ 21126 index - a very productive engine. Among other things, this version was equipped with brake components from AP-Racing with 200 mm 4-piston ventilated front disc brakes and 135 mm 2-piston rear disc brakes.
So-called semi-sports seats with pronounced lateral support are installed here. They have a long cushion, but are also designed in a “sporty” way.
Differences between the Granta-Sport and 21126 engines (Kalina-2 with automatic transmission)
Structurally identical motors can develop different power. Improving performance begins with installing other spark plugs, more accurately selecting the advance angle, etc. Perform tuning yourself, “squeezing” 120 hp out of the Kalina-2 engine. – however, it will not succeed. The 120-horsepower Granta-Sport engine is built on the basis of the 21126, but has differences from it.
The engine of the Granta-Sport car is no less durable and reliable than the prototype (the 21126th engine of the second Kalina). To increase power, different camshafts are installed here (with a modified cam profile). Reducing the exhaust-intake resistance is another, and final, “mechanical” change. It was possible to achieve maximum power by changing the firmware.
The developers of Granta-Sport assure that up to 3,000 rpm, the engines “behave” the same. But driving at speeds above 3,500 cannot be called economical. We conclude: installing a Granta-Sport engine in a Kalina-2 with an automatic transmission is a low-use (but even more expensive) tuning method.
What about Kalina RC?
The rally version of the “second Kalina” uses an atmospheric engine (also based on the “26th”). It features forged pistons, which are lighter than stock cast pistons. It is unlikely that you will be able to carry out such tuning on your own. Tolerances must be “maintained” even more accurately than at the factory. What is most often “forgotten” when offering to buy tuning parts.
In addition, the engine was boosted. The compression ratio has increased, power has increased (up to 155 horsepower), however, durability has significantly decreased. The period of operation of sports cars is less than 1,000 kilometers (then the car is sent for overhaul). We will leave the choice to the consumer.
Motor power function 21126
There are other tuning methods. For example, the installation of turbines, which is officially 100% prohibited.
The maximum moment of force on the Granta-Sport engine shaft is 140 N*m, “Kalina RC” is 175 N*m. All of the above suggests the following: the serial engine 21126 has potential for tuning. But the benefits of the changes are unlikely to be achieved without replacing mechanical parts (including ShPG elements).
However, a more affordable upgrade option, the so-called “chip tuning”, also makes sense. Which is true for most power units produced by VAZ. The question is what exactly needs to be achieved in the end.
Answers (2)
The engine installed on the Lada Granta Sport is a serial 16 valve engine from Priora, but with some modifications.
Thus, in the sports version of the engine, camshafts with a modified cam profile are installed, which is reflected in a more complete filling of the cylinders and better purging of exhaust gases. In addition to this, the brains of the ECU were “reflashed”. Also, the intake and exhaust resistances in the engine were reduced, which overall gave an increase in power, and the engine output began to amount to 120 hp. and 154Nm of maximum torque. For comparison, the engine of the Lada Grand sedan is 106 hp and 145 Nm.
The main increase in traction occurs at high engine speeds, and up to 3000 rpm, the engine characteristics essentially remain the same. To pick up the “bottoms,” the engineers modified the gearbox (5-speed manual), where a main pair with a gear ratio of 4.3 was installed (the base had 3.7). This made it possible to accelerate to the first hundred in only 9.5 seconds and raise the maximum speed to 197 km/h in fifth gear (Grand sedan 177 km/h). In this change to the standard series of gear ratios, the fifth gear was almost straight, rather than overdrive, and the fourth turned from direct to intermediate. At the same time, fuel consumption was 7.8 liters per 100 km. Gasoline AI-95.
But about the Lada Granda Sport Turbo engine - purely for sports competitions on closed tracks
The basis is the basic 1.6 liter VAZ 21126 engine, which after modification received the TMS index -21126-045. The engine is equipped with turbocharging (excessive boost pressure of 1.2 atm) and develops maximum power from 235 to 240 hp (depending on the setting) and 280 Nm of torque. Acceleration from 0 to 100 km/h takes 5.6 seconds.
The cylinder block and cylinder head are basic, and the piston group is of its own TMS-Sport design. The engine crankshaft is created on the basis of a serial one, but using special hardening technology. In the cylinder head, the intake and exhaust channels have been modified, new camshafts with a modified cam attack have been installed. To increase reliability, the oil pump was modified and the engine heat transfer process was improved. The turbine control system has been specially developed. The engine control unit has also been modified in TMS Sport.
For the World Circuit Racing Championship, a turbocharged 1.6-liter engine with 300 hp was developed to meet the requirements of the new WTCC regulations.
