About LADA 2109 engines 1st generation (1987 - 2011)

VAZ 2109 (Lada Samara), popularly known as a nine, is a five-door hatchback, a continuation of the Samara line.
It was developed in 1987 using the three-door hatchback VAZ 2108 as a basis. The nine itself became the basis for the creation of the VAZ 21099. The car became widely popular thanks to its rapid design, good engines for those times, as well as a practical five-door body. All this, coupled with its low cost, as well as a wide selection of spare parts, made the VAZ 2109 very attractive. This attractiveness was passed on to its successor, the VAZ 2114. In contrast to the VAZ, the injector was installed as standard on the 2109 engines (power unit 2111).

In addition to the injector, the 2109 was equipped with a carburetor with a displacement of 1.1 l, 1.3 l and 1.5 l. Such engines can be seen if you look under the hood of the 2108.

In the article we will look at the engines themselves for the VAZ 2109, their characteristics and weaknesses.

The 1.3 engine is the base for the eight, it was developed from scratch, and is structurally similar to the 21011 1.3 liter engine. there is nothing in common. This engine became the basis for the creation of power units for installation on the Samara family with a displacement of 1.1 liters and 1.5 liters. This is an in-line carburetor type engine, has 4 cylinders and an overhead camshaft. The timing drive uses a belt.

Regarding the service life of the engine, it is fair to say that careful and quiet operation, proper and constant maintenance will allow you to exceed the official 120 thousand km and the service life can be 180-200 thousand km.

In terms of disadvantages, the following are most often noted. The parts of the cooling system wear out quite quickly. Frequent oil filter replacement and valve adjustment will be required. Oil leaks often occur due to unreliable seals of the valve cover, fuel pump and distributor sensor. It should be noted that unreliable Solex-type carburetors in general, and EPHH in particular.

If the timing belt breaks, the valves may bend. Also, over time, problems with ignition and engine tripping may occur. In addition, due to ignition problems, the engine may detonate. Another reason for this may be low-octane, low-quality fuel. Detonation is indicated by black smoke coming out of the exhaust pipe and loss of power.

Engine VAZ 21081 1.1 l. is an analogue of the power unit 2108 1.3. However, it has a crankshaft of less stroke, and as a result, reduced traction. This is an in-line carburetor-type engine with four cylinders, an overhead camshaft, and a timing belt. As for the resource, if you ensure careful operation and quality maintenance, you can count on an official 125 thousand km.

The difference between 21081 and 2108 is due to the reduced piston stroke and, as a result, the reduced displacement. In addition, the difference is a lower cylinder block compared to 2108.

The VAZ 081 engine is rare, as such engines were exported. This is probably for the best, since this is a frankly frail unit. It should also be remembered that if the timing belt breaks, the engine may bend the valves. ENGINE VAZ 21083 This engine is the progenitor of the current power units for Lada; it became the basis for 16 valve engines 2112, 124, 126 for Priora, 127, 114, 116, 194 for Kalina.

The replacement for this engine was the same injection-type version. VAZ 2108 1.5 l. is an in-line carburetor-type engine with four cylinders and an overhead camshaft. The timing drive uses a belt; if it breaks, the valve slide will not bend.

What does the initial acceleration depend on?

The traction force of the Priora depends on the gear ratio in the gearbox, the so-called transmission. The latter consists of a clutch (the connection between the gearbox and the engine mechanism), drive shafts and a gearbox, which transfers power and torque from the engine to the wheel shafts. Gear ratios can be of: 2 types.

If you need quick acceleration to 100, then use gear ratios with a short ratio.

In addition, the Lada can accelerate faster if the number of the main pair is increased (for this family the standard number is 3.7). It is believed that setting the pair to 4.1 or 4.3 allows you to get a noticeable (but is it necessary) advantage for breaking away at a traffic light, and sports models are equipped with modifications with numbers 4.7 or 5.1 (for crossovers). Cars used in urban environments, where acceleration to 100 is not necessary, are equipped with a gearbox with a balanced series of gear ratios, which does not provide rapid acceleration, but provides high speed, if necessary.

It is worth remembering that not every Priora will withstand the load from additional numbers for a long time with a standard clutch. That is why when tuning you need to install more durable and reliable components that are produced by AP LockheeD or “Luk”. You should also think about purchasing high-stiffness springs and cermet discs for the clutch basket. In addition, to reduce the load on the clutch, crankshaft and gearbox, you can install a lightweight flywheel for the Priora, which is on average 2-3 kilograms lighter than the standard one (additional fuel savings). But experts do not recommend lightening the crankshaft, because in a garage, or even most car repair shops, it is impossible to select balancers for the connecting rod journals for a new shaft, which can lead to the collapse of the entire system.

Lada Priora has a slower acceleration to 100 kilometers per hour than, for example, a rear-wheel drive model with the same engine characteristics, since the basic configuration of this car is not intended for sports. Therefore, it has a lighter torque transmission design and no cardan, which adds greater controllability and efficiency to this urban car.

When the question arises about buying a low-budget car or a car for a beginner, usually the first two models that come to mind are the VAZ-2107 and VAZ-2109. Even today on the secondary market you can find copies up to 30 thousand rubles.

Both cars were released in the 80s of the last century and, despite their age, are still popular among buyers. Over the past month, “seven” was struck 32,311 times through avtocod.ru, “nine” - 18,271 times.

We decided to find out which is better - VAZ-2107 or VAZ-2109, and compared the cars with each other. Who is more fragile? Who's the sharpest on the move? What problems might competitors have with selling on the secondary market? Let's figure it out.

One brand - different approach to design: who is sharper on the move

“Seven” is a direct successor to the Fiat 124, which was developed back in the 1960s of the last century. Compared to modern cars, it has neither a smooth ride, nor steering sharpness, nor composure. At high speeds the car floats, so it feels completely uncomfortable on the highway. But the cross-country ability due to the ground clearance of 170 mm is excellent.

And because of the rear-wheel drive platform, the car can be turned from a boring family sedan into a drift car for winter rides. True, for these purposes the suspension will have to be modified.

The “Nine”, although it came off the production line in the same decade as the “Seven”, has a more modern design. Thanks to the Porsche and ItalDesign specialists who had a hand in creating the Samara. The car received a new front-wheel drive platform and suspension design, so it handles much sharper than the “Seven” and seems more collected and obedient on the move. But the ground clearance here is 1 cm less, and, accordingly, the cross-country ability is worse.

At the front, the “nine” has an independent MacPherson strut, and the “seven” has double wishbones. The designs are simple, reliable and rarely present “surprises”. Most often, ball joints and wheel bearings fail in both cars. The cost of parts is from 500 to 1,000 rubles, replacement will cost about the same. The Sema's rear brake cylinders also become sour - we recommend changing them as often as the pads.

Why does Priora jerk when accelerating, jerks in motion?

The car should accelerate smoothly. The car jerks, this is either due to your switching, or to the box itself. Jerking is usually present on a faulty machine. But if Priora is in good working order, it will show a fairly decent result. Everything will depend on the skill of the driver. In addition, the following parameters must be observed in order to repeat and exceed the performance from the test site:

• vehicle weight;
• weather;
• quality of road surface;
• driving style;
• the accuracy of the stopwatch with which acceleration time is measured.

If, when all these conditions are met, it is not possible to achieve a normal acceleration time and jerks appear, you need to change the gear shift process. This problem can also occur with automatic transmissions - for an automatic transmission this is almost a standard problem that needs to be repaired.

How to fix jerking, what to watch

When jerks appear when accelerating and even at low speeds the Priora jerks, you need to first try a smoother shift when accelerating, “listen” to the car. If jerking persists during smoother gear changes and stable acceleration, pay attention to the gearbox and clutch basket.

The oil inside the gearbox must be changed on time, and it itself must be clean so that the gears shift cleanly. The slide must not be damaged - all grooves must be visible, and the corners must not be smeared. A burned clutch is a surefire way to delay gear shifting. After correcting all the problems, you can begin to learn how to overclock.

In cramped conditions, but don’t be offended: which car has more space?

It will be easier for rear passengers to fit in the 2107, although the differences in the size of the cars' interiors are minimal, and it is better not to travel in either one on long trips. If you are 180 cm tall, on the back seat of the “nine” you will rest your head on the ceiling and your knees on the backs of the front seats. In the "seven" there is a little more headroom.

It is more comfortable for the driver to drive the Samara. Firstly, due to the overview, especially for the standard mirrors of both cars, and secondly, due to the fit and location of the controls. The seats here are also more comfortable than in the “seven”. They have more developed lateral support, and the filler material sag less over time. If you are looking for a “nine”, look for one with a low or “European” panel. The high panel rattles a lot on bumps.

Nominally, the trunk of the VAZ 2107 is larger - 379 liters versus 330 liters for the “nine”, but due to the folding seats and body type, the second one wins in terms of cargo capacity. The loading height is inconvenient for both cars.

Neither VAZ has even a hint of comfort options. The only thing you can find is electric windows in the VAZ-2109. Otherwise, these are gray and nondescript cars. Thank God, at least the instruments are readable.

How to properly accelerate in a Priora

The skill of correct acceleration will be similar to playing sports: first you need to learn the theory, then try to make the movements slowly. Only after this should you try to make the correct acceleration. The main work will be done to get the speed right.

During everyday driving, almost every driver changes gears with a movement practiced to the point of automaticity, which may be lubricated - the transmission does not shift at the right moment, but the car will still go. During this moment, her speed will drop, which cannot be allowed. The Priora's engine needs to be turned so that it moves - and there is no drop in speed.

The scheme is as follows:

• in first gear you need to start from 800 to 2 thousand rpm;
• on the second - from 2 to 4, then the third: from 4 to 5 thousand revolutions. The key is don't under-rev and don't push the car too hard.

Option two:

1. or it will stall in place;
2. or it will make noise, but will not go anywhere.

Remember that from 2 to 4 thousand is the maximum torque of 126 motors, then the torque decays. You need to hold out for this second, switching strictly “like in a driving school.” You'll have to perfect your movements. With such acceleration, you will reach one hundred in third gear. Consumption will not increase much if acceleration is smooth.

Which is faster: VAZ 2107 or 2109

In total, the “Seven” has 13 modifications with different engines, which were equipped with four- and five-speed manual transmissions. More often there are three engines on sale: a “five” carburetor 1.3 liter with 64 liters. s., carburetor 1.5 l per 71 l. With. and injection 1.6 liters for 72 liters. With. On the last two, the timing drive is chain, which means that most car enthusiasts will not be able to service it themselves. In the service, the replacement procedure costs about five thousand rubles.

The “nine” also has three engine options. Depending on the years of production and modifications, their power varied: carburetor 1.3 liters - 64–68 liters. s., 1.5 l - 68-77 l. With. and injection 1.5 l - 77.8 l. With. The timing drive here is belt driven and can be easily changed even on the highway. And in general, 2109 is easier to maintain.

It's the little things that most often fail in motors. For the “nine” it is a starter solenoid relay, for the “seven” it is a pump. The cost of the part is about 1,500 rubles.

You will also have to deal with adjusting the valves and carburetor. You can learn to perform both procedures yourself. And in general, rivals can be good teachers in terms of self-repairing a car.

The VAZ-2109 is faster than the Sema in accelerating to 100 km/h by as much as 2.5 seconds (12.5 seconds versus 15 seconds, respectively).

I would choose 16 valves and wouldn't even look at 8.

But the 16 valve valve still has more advantages!

Last winter began with cold weather, and therefore it would be a shame not to remember the characteristic disease of sixteen-valve VAZ engines - difficult starting. A couple of years ago, factory workers overcame the defect. The transition from the January-4 controller to Bosch-M 1.5.4 and January-5 seemed to give a positive result. In the winter from 2000 to 2001, a car equipped with a “January-5” controller and a J5V05F16 control program easily started up to -25°C. He overcame the next season with a tuning program (ZR, 2001, No. 7). Despite the very mild winter, we still managed to test its starting properties. The same -25° degrees did not take the serviceable motor by surprise. And this is the current season. He was greeted armed with the latest version of the factory software. There was no reason to worry, but my instinct told me to stock up on a couple of cans of ether-based starting fluid. You guessed it! Starting difficulties begin at minus 22-23°C. If it’s lower overboard, it’s better not to approach the car without a magic potion. Factory workers should think about it - where did they have to make such a mistake that even companies specializing in chip tuning now refuse to improve the starting properties of sixteen-valve engines? He writes while driving. and also what pulls from the bottom 8 is better than 16, this is definitely proven! Here, in principle, there is a dispute about who has the motor rolled out and what consumables! But I don’t argue that the 16 is faster at speeds from 120. But in service. especially the Kulibins’ ass if they get stuck on the highway!

What you will have to face when buying VAZs

The main drawback of 2107 and 2109 is the poor quality of spare parts and metal. “Saffron milk caps” appear very quickly and almost everywhere. The “nine” most often rusts the trunk lid, rear fenders, bottom of the sill and bottom of the doors. The doors, sills and bottom of the “Seven” are rotting.

On the VAZ-2109, in addition to the “saffron milk caps,” the door handles will also annoy you: they constantly jam and do not open the doors, so immediately after purchase it is better to change them to the “Euro version” (issue price is about 2,000 rubles).

What to take - VAZ 2107 or 2109 and for whom

By modern standards, both Ladas are very outdated. There is neither safety nor the slightest hint of comfort in them, but with them you will learn a lot both in terms of driving and in terms of maintenance.

Both cars are best considered as a first or temporary option. “Nine” is more preferable for beginners: it is easier to control and easier to repair. “Seven” is suitable for fans of winter “drifting”. The rest is just a matter of taste.

Which car from this pair would you prefer and why? Write in the comments.
