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.

Racing model? Granta Sport 2022 - review
The characteristics of the premier 2011 Lada Granta Sport, at first glance, were not impressive, although “from the start” it was developed specifically for circuit racing. Under the hood was installed a 4-cylinder turbocharged 1.6-liter engine with a torque of 300 Newtons per meter, paired with a sequential 5-speed gearbox. Even though this engine then developed “only” 235 horses, the car entered the pool of the strongest. Granta Sport produced such characteristics and proved itself in such a way that by 2014 the so-called “civilian” model was developed.
As for the appearance of the updated Granta, the designers in the 2022 modifications “redrew” the configuration of both bumpers, and for their manufacture the designers recommended not plastic, but the now very popular fiberglass - a much more practical and durable material. A small (and we especially emphasize - factory) spoiler was installed on the trunk lid, the ground clearance was reduced by 20 mm and the shape of the radiator grille was changed. By default, the “sporty” Granta is now available not only with standard “civilian” ones, but also with solid 195/50 R16 wheels.
"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.
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:
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.
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.
Synchronizers
They decided to change the gear part a little. Multi-cone synchronizers were installed in first and second gears, which increased the reliability of the unit and reduced the effort when engaging these gears. In the future, the Lada Granta VAZ-2181 box will be installed on cars with more powerful engines, so the diameter of the clutch, which has a larger moment of inertia, has already been increased. On the old manual transmission, the clutch housing accommodated a maximum disc size of 200 mm; the new housing allows the installation of 215 mm discs. These changes forced the developers to change the location of the starter; it is now located along the engine, and not along the box, as before.
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!

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”).
Grants box shift mechanism
Many important elements of the old manual transmission were located at the bottom and were bathed in an oil bath - the shift mechanism, the rod clamps and reverse forks, the gear set seal, the reverse light switch. All of these elements were potential sources of leakage. Many people solved the problem with sealant, but moving the elements upstairs solved the problem once and for all.
The new gear shift module on Grant is a separate mechanism that, if necessary, can be removed without disassembling the box. The mechanism has a selector grille that clearly follows the gear shift pattern and prevents accidental engagement of reverse gear.
The center detent now rides on the center plate and transfers force to the lever without sliding bearings. This solution made it possible to eliminate all mechanical losses and increase the information content of switching.
Standard equipment for all Grant models:
1. Standard 2. Standard plus 3. Classic 4. Classic start 5. Comfort 6. Comfort optima 7. Luxe 8. Luxe prestige
And here is a (not yet complete, moreover) list of additional options for the highest version called Luxe prestige, which AvtoVAZ offers:
• ESC system coupled with traction control • airbag not only for the driver, but also for the front passenger • front seat belts with pre-tensioning when the car hits an obstacle • three L-shaped headrests for the rear seats (they “know how” to hide flush with the backrest and do not interfere rear view) • alarm when the driver's seat belt is not fastened • rear seat belts - modern three-point • ISOFIX mountings - for installing child seats • safety bars in all 4 doors • brake discs - ventilated • hill start assist system • muffler made of alloy steel ( stainless steel)
And between these two trim levels (Standard and Luxe prestige) there is a whole field of diversity in filling with additional options. Compare the maximum configuration with the Standard configuration, where the car, as other buyers put it, is “empty as a drum,” and you will realize the true width of the “price range” - from 369 thousand to 594 thousand rubles.
The electrical equipment of the “most sophisticated” version uses a modern so-called Can-bus, which significantly increases the performance and reliability of all vehicle systems. The motor pistons are coated with graphite, which significantly reduces the coefficient of friction when starting a cooled motor. Plus DRLs - newfangled running lights.
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.
An interesting photo has appeared on the Internet; it shows a road train transporting Lada cars, including several Lada Vesta SW Cross off-road station wagons.
Specification for bodies
But what we should dwell on in more detail is the bodies. The sedan body is honored not only by Russians, and for these reasons.
If in relatively warm Europe or the USA, where frosts occur exclusively in the strip bordering Canada, you open the trunk of a hatchback or station wagon “for a minute,” then nothing special will happen to the temperature of the cabin and to the well-being of passengers. And you try to open the trunk somewhere higher in such a body in winter at minus “at least” 20 degrees Celsius... The interior will get cold not even in minutes, but in seconds!

From practical experience
Since this car is still from the budget segment of the global automobile industry, the buyer should be prepared for “crickets” and creaks in the sedan, and for the rattling of the shelf covering the luggage compartment of the liftback. If we take as “the norm” all these squeaks and crickets and in general the “traditionally Russian” quality of interior assembly, then car owners have practically no special complaints about the body of this car. It (the body) is quite durable, well-welded and will be worthy competition for other budget foreign cars.
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)
Standard camshaft
The lift of the 16 valve camshaft is 7.55 mm, the valve opening angle is 273 degrees. valve overlap 0.3 mm.
Not the most important parameter when choosing a camshaft, it characterizes the maximum amount of valve lift and, as a result, the pushing/suction of a larger amount of the fuel-air mixture from the combustion chamber per unit time. We called it not the most important, because there are other ways to increase the amount of mixture entering the cylinders through the valves (for example, installing valves of larger diameter). High lift is preferred for high-speed and high-volume engines.
Full base camshaft, not full base camshaft
The camshaft lift is determined by the formula Lift = A-B where A is the distance from the camshaft axis to the top of the cam, B is the distance from the factory base to the camshaft axis. How in
It is clear from the formula that you can increase the camshaft lift either by increasing A or decreasing B. When the workpiece does not allow you to further increase distance A (there is not enough “meat”, usually when the camshaft is made from a standard workpiece), they begin to reduce distance B and distance B1 appears, and, as can be seen from the formula, the camshaft lift increases. When installing a partial camshaft, in order to compensate for the gap that appears between the base and the valve, so-called “thrust bearings” or “tablets” are used - this is a set of circles of a certain thickness. The use of partial shafts in sports is highly undesirable, since the overall design loses reliability with the appearance of unnecessary parts.
Plug-inless motors again
From the latest news about Grant and AvtoVAZ engines: the plant is going to return to the so-called “plug-in” engines, and the first to try on the new engine line is the restyled Granta.
What are we talking about? Not only motorists (they know this thoroughly), but also many car owners are afraid of the situation when 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 have different pistons with a special selection in the bottom... exactly the size of the valve heads, which will help avoid those very “critical consequences”. The official supplier of engines to the AvtoVAZ conveyor, Federal Mogul, has already mastered their production, and the changes will affect: - 8-valve VAZ-11186; — 16-valve VAZ-21126; - 16-valve VAZ-21127, - ... which are exactly 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 also soon receive this same “plug-inless” version, but in the future, and the new VAZ-21179 units with 122 hp. With. (volume 1.8 liters) and VAZ 2190 Sport will “get by” for now.
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.
Granta Sport camshafts - characteristics
The most popular camshafts are with the following characteristics: lift 9.55/9.15, phase 286/230. They are praised for their “ability” to spin even beyond 7,000 rpm. But as for “motors in general,” the most popular question is: maintainability and reliability. So, all of them (ALL engines) are extremely reliable and virtually indestructible, provided, of course, that competent and systematic routine maintenance prescribed by the manufacturer is observed. And when purchasing a used Granta, we recommend that diagnostics be carried out exclusively at a branded service center, or, in extreme cases, at an AvtoVAZ-certified enterprise.
As for the gearboxes, all three gearboxes are problem-free. The 5-speed manual transmission is a native VAZ development, and 4- and 5-speed automatic transmissions “came” to AvtoVAZ together with the Renault-Nissan alliance, and are also considered by professionals to be the standards of the global automobile industry. In particular, these boxes are found on most Renault models, starting with Logan and ending with Laguna, and in the Nissan line - this is almost its entire passenger model range from Micra to Almere.
Tuning and sports camshafts
Each of us tries in every possible way to improve our car, and there are a great many ways to achieve this.
When it comes to the engine, everyone unanimously talks about increasing its power. Although, if we take a more serious approach to the issue, then first we need to pay attention to its torque. We know that it is possible to squeeze out the most power at a stable maximum speed, but this engine mode is rarely used. For the average driver, what is more important is the car’s throttle response, which obediently responds to the gas pedal both when moving from a standstill and when accelerating. This behavior of the car is ensured by large and relatively constant torque at low and medium speeds, which is what VAZ engines “sin” about. At low engine speeds they do not have sufficient “traction”.
Owners of a VAZ car often complain about the car jerking when starting to move, noticeable dips when sharply pressing the gas, many have a fast clutch, and almost everyone notes the ineffectiveness of fifth gear. Indeed, at engine speeds less than 3000 rpm. its insufficient pickup capacity is observed. The torque curve depends on the valve timing parameters, the so-called “camshaft phases”, as well as the “time-section” of valve opening, which are determined by the profile of the camshaft cams. Depending on its angle of rotation, different amounts of valve opening are obtained. For better functioning of the car at low speeds, they quickly supply the required volume of working mixture into the cylinder, that is, they noticeably narrow the opening phase of the intake valve.
Unlike conventional camshafts, sports models use cams with different geometric dimensions. Their taller and wider shape means that the valve rises to a greater height and stays open longer, which ensures the supply of a complete mixture. The profile of the cams is characterized by a smooth shape, which makes the operation of the gas distribution mechanism more reliable at wide phases.
From the above it follows that the maximum engine power and its torque can have different values. And if the use of a standard camshaft implies increased torque at medium speeds, then the sports one provides maximum output at high engine speeds. The sports camshaft on VAZ cars is installed with a split gear (camshaft sprocket or pulley), with the help of which more precise adjustment and adjustment of the phases becomes possible. With its help, the maximum power is adjusted at the required engine speed.
By using tuning camshafts, you can achieve engine operation under load without noticeable interruptions, even when the speed is reduced to the maximum level. At the same time, the detonation limit moves away, that is, the “knock of fingers” at low and medium crankshaft speeds stops. There is a noticeable reduction in fuel consumption and exhaust toxicity. As a result, the engine’s tendency to detonate decreases, which means its service life increases.
Camshafts on VAZ engines are quite sensitive to gap adjustment, so on tuning camshafts the cam run-off area on the valve closing side is noticeably increased. This makes it easier to adjust the gaps and reduces their number several times. Let's trace this fact using the following example: after installing a tuning camshaft, valve clearance adjustment is required after 60,000 km of engine mileage. Using a conventional camshaft would require at least four adjustments. This significantly increases the service life of the product and saves money and time required for each valve adjustment. Do the math for yourself: proper adjustment takes at least 3.5 hours and costs about $20.
The result of modernizing the Granta box
Gear shifting has become clearer and easier, and vibrations on the gear shift lever have been eliminated.
Minimal changes in the internal design made it possible not only to improve the quality of gear shifting, but also to make the entire unit more reliable and demanding of the driver.
The manual transmission VAZ-2181 became the first AVTOVAZ gearbox for which a complete computer calculation of all parts subject to loads was carried out.
The volume of oil in the Granta box was reduced by a third, the factory began to fill in semi-synthetic rather than mineral water, the oil itself now does not require replacement for the entire service life of the car - five years or 200,000 kilometers.

Features, malfunctions and repair of the Lada Granta Sport engine
The basis for the creation of the first serial sports engine was the 21126 Priora engine, with a lightweight ShPG and, very importantly, with wider shafts. This engine was equipped with TMS lift camshafts 9.55/9.15, phase 288/282, modified intake, exhaust with a spider, and of course its own firmware. All this added up to a smooth engine, running from the bottom without problems and developing about 120 hp. See the measurement schedule below.
By nature, the engine up to 3000 rpm drives like a regular 126 engine, then it’s faster until the cutoff. Fuel consumption on the Grant Sport has remained virtually unchanged (with quiet operation). Otherwise, this is a Priora engine with all its shortcomings and features, the malfunctions and their causes coincide one to one, we read about them in the section “Faults 21126”.
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.
