What is the modification of a VAZ 2107 with your own hands, it will probably be useful for all owners of the classic Zhiguli to know. Although production of the model was stopped in 2011, this does not mean that you can forget about it, and the seven will be seen on all roads in Russia for many years to come. Because it was sold in unlimited quantities during the entire production period. And tuning classic VAZs has become a habit and is already akin to a certain ritual for the owners of these models.
Do-it-yourself modification of the VAZ 2107 is usually carried out in several stages. They start with the appearance of the machine (and here, obviously, there is something to improve). The interior decoration of the cabin and its amenities can also be significantly modified with your own hands, based on the available funds and expected investments. It often happens that all the mince of this not too expensive model weighs much more in money than its real cost (especially if the car is used).
Airbrushing and the application of artistic tuning to some parts of the body are also popular (although on the 2107 it looks very funny, especially from other drivers, but if you have the inscription “Tazs are knocked down” pasted on the glass, then it’s okay). In terms of engine modifications and improved driving performance, there is also something to work on. As they say, there is no limit to perfection. In this article we will talk about only a few popular improvements that are especially popular among owners of the legendary seven.
Appearance
Among the most popular and less expensive modifications are the installation of spoilers and a wing. In principle, both of them are quite functional things (though, rather, for racing and sports cars). So, in addition to taking care of beauty, you also get an improvement in the aerodynamic properties of your car.
Spoilers can be purchased at any auto store. It's easy to install them yourself, following the instructions. Some craftsmen make the wing from light metals on their own, but you can also buy it in the store. Installing it is also quite simple (usually on the trunk lid) - anyone can cope with the task.
The radiator grille is replaced with a more modern one. This procedure will not take much time and effort, but the appearance of your car will become more solid (or sportier - depending on the type of grille you choose). And some also add an overlay to the front bumper. Here you will have to tinker a lot, since you need drawings, measurements and templates. It is better to perform this operation with the help of, for example, a neighbor in the garage who has already done it.
You can install alloy wheels and lowered tires, which will significantly improve the modernity of the car. It couldn’t be easier to do this - there would be money allocated for modernization, because four good wheels from well-known companies and four high-quality tires would already cost a tidy sum. Well, everything is simple here: I bought it and changed it (on my own or at a tire shop).
Regarding the modernization of light and optics:
many install the popular xenon. They also improve the optics itself through which the headlight light passes. You can also install LED lights: both the headlights themselves and the car body. But this procedure is not for everyone, since at night the car turns into a Christmas tree. You can get by with a mini option: LED illumination of headlights and dimensions, rear numbers. And very light - the bottom of the car. Then, at least, it won’t look too wild at night.
Rear beam stabilizer bar
The element's purpose is to reduce the lateral roll of the car, improve the interaction of the wheels with the road surface when cornering, as well as distribute the load between the rear shock absorbers when one of the wheels drives over uneven surfaces.
The fact is that when you hit deep potholes, extremely strong suspension occurs, often causing the rear shock absorber strut rod to be pulled out.
When working in compression, the shock absorber, on the contrary, is overly susceptible to breakdown, which seriously affects its durability.
This does not happen with amplification. The resulting force is distributed between both wheels with an approximate ratio of 3 to 2, which has a positive effect on the quality of control and the reliability of the suspension elements.
The stabilization bar is installed directly on the rear beam of front-wheel drive models of domestic VAZ and other cars.
Installing a beam reinforcement should not cause any problems for most drivers. To do this, you need to use a trestle or inspection hole, and then fasten the rod to the beam according to the instructions.
The only difficulty that may arise is the need to drill eight holes in the beam housing.
Salon
For many car owners, this is a source of personal pride. In this temporary house, the owners tend to collect all possible innovations for coziness and comfort, fashionable gadgets and completely necessary features.
To begin with, update the casing
. Of course, the leather interior on the seven will look a little strange. But it is quite possible to take care and purchase beautiful modern materials, paying attention to the selection of colors and the quality of the material. Reupholstery is usually done with the help of a craftsman who is well versed in this (because there are certain nuances). But you can master it on your own with the guidance of the Internet (on forums they usually share advice and even put entire master classes on public display).
Types of work on tuning "Seven"
What types of work are there to upgrade such a domestic car? As a rule, the performance of the car interior, engine, and also the appearance of the vehicle are improved.
Everyone knows that domestically produced cars are not distinguished by excessive “stuffing”. For a driver who loves comfort above all, who has a desire to operate a serviceable, safe car, tuning the VAZ-2107 is simply necessary.
In the cabin, you can change the steering wheel, trim, install a good audio system and much more. As for upgrading the “filling”, car enthusiasts get to spark plugs, cylinders, a carburetor and more. External transformations are carried out by replacing wheels and painting the car.
Turbo principle
To increase engine power, you need to increase the fuel supply. But that’s not all; in order for this fuel to burn completely, the air supply must be increased. Domestic classics were produced with naturally aspirated engines, but here you can’t jump over your head. You can increase the volume of supplied air using various devices. For example, a compressor successfully used in models. However, the compressor is practically not used by other manufacturers. Another device that is much more popular is the turbine.
The turbine cuts into the exhaust system and, using the excess pressure of the exhaust gases, forces atmospheric air into the cylinder block.
Tuning the interior of the VAZ-2107
So, tuning the interior of the VAZ-2107. It is much more pleasant and comfortable to be in a beautiful salon, because both your mood and attitude towards the driving process directly or indirectly depend on this. Tuning the interior of a VAZ-2107 may include various manipulations.
Most Seven car owners are dissatisfied with the steering wheel. Even the one that comes in cars produced in the last 2 years. Drivers complain that with such a steering wheel, driving a car becomes much more difficult; driving does not bring pleasure, but only causes discomfort. Therefore, this problem requires improvement. Most owners change the steering wheel to a smaller one.
Improvement is also really needed in the area of seat upholstery. Naturally, sitting will not become more comfortable, but the appearance will be much better. As an option, you can purchase ready-made kits for upholstery of seats. Kits from the 1993 Toyota Corolla are well suited to the “Seven”. Another option is to simply buy the material and replace the seat trim using special glue. The dashboard can be covered with materials of different composition and color. It all depends on the personal preferences of the car owner.
Conversions can be made regarding the rear view mirror. In this case, everything is simple: attach a new large mirror to the standard one. The next step in improving the car could be replacing the sun visors with tuning ones.
It often happens that there is not enough space in the cabin to distribute all sorts of little things; there is simply nowhere to put them or place them. To eliminate this problem, you can do the following: ready-made kits with various stands and pockets are available for sale, which will be an excellent addition to the dashboard.
Don't forget about the audio system. For lovers of high-quality sound, the car interior should be equipped with a good audio system that will turn the driving process into a pleasure.
The improvement in the trunk also cannot be ignored. Many owners of Sevens and VAZ-2105 resort to fairly simple methods of converting the trunk. Often you create a raised floor for the trunk with your own hands. To do this, you need ordinary boards, which need to be connected in such an order that you get a convenient design with compartments, sectors, into which you can then place various objects, so that there is order in the trunk. In addition, many resort to welding the spare wheel into the trunk floor (suitable for both VAZ-2105 and VAZ-2107), gluing special material for sound insulation (this is mainly necessary if a subwoofer is placed in the luggage space - this way the sound becomes cleaner and better quality).
Engine Lada 2101-2107. Boring of cylinder heads. Part 2.
The story will mainly be about how the cylinder head of the VAZ 2101-2107 was modified:
After disassembling the block, it was time to disassemble the cylinder head. To do this, I needed a tool: a desiccant and a beater for the valve guides. This was all bought. A universal beater for engine repair, of this type:
1. Desiccant - 120 rubles 2. Set of mandrels - 200 rubles 3. Key for lapping valves - 70 rubles
I sorted everything out without a book, let’s say by intuition. =) I really like to figure out everything myself, how and what is taken apart and done, moreover, with a full understanding of the operation of the system. Among the peculiarities during disassembly, I will say one thing: some valves do not want to come loose. This is not a reason to be upset = ) ) ) Take a spark plug wrench, place it on the valve plate and hit it with a hammer or sledgehammer. Then you take the desiccant again and everything desiccates perfectly. If you know this method, you will dry out the valves in 5 minutes. The guides are easy to knock out, there will be no difficulties with this! The rule is: knock out the cylinder head on a cold one, hammer in on a hot one! Then everything will be as it should!
I laid out all the spare parts neatly on the shelves so that they weren’t lying around underfoot and everything was correct and clear. It was necessary to do this from the very beginning of analyzing the engines... everything comes with experience!
Then it was time to cut the intake manifold and cylinder head. After practicing boring channels on a test manifold, I realized my mistake - I was taking the channel in the wrong direction. It's not very good. I think I wasn't the only one who had this error. Here's what it is:
crookedly bored manifold
On the left is a smooth, undirected channel, on the right is a curved and directed channel) the difference, I think, is noticeable to everyone. What is the method for smooth boring of a channel? I found a way to avoid such channel slippage so that everything would be smooth and the channels would be round. This method is just banal drawing. The manifold channels are smooth and round by nature (unlike the cylinder head channels). Therefore, you measure how many millimeters you need on each side and draw... like this:
And now you definitely won’t take away the channel. You will know which direction to move. A very convenient method. I recommend it to everyone. Seven times measure cut once. I sharpen the channels with sandpaper, but it’s a chore, I agree, but it’s still reliable. The chances of cutting into the cooling channel are low. Therefore, work is much calmer. The tool is used like everyone else: drill -> hose put on a little and tightened with a clamp -> fabric (rags) -> sandpaper wrapped overlapping. The downside of this tool is that the hoses often break. After a long time of sawing the channels, washing and externally sanding the collector, it turned out like this:
Hooray! The collector is bored out. Channels are 32-33 mm in diameter. That is, the exhaust valve fails and dangles in the channel. Sharpening the commutator is very tedious. The problem is the hoses keep breaking...so be patient. After the collector wasted away, he decided to go buy some goodies:
So, here is a complete list and prices for all parts: 1. Reamer for valve guide - 200 rubles 2. Pin driver - 100 rubles 3. VALEO clutch - 2700 rubles 4. Main and connecting rod bearings ZMZ - 185 and 149 rubles 5. Set of engine gaskets – 495 rubles 6. SM rings – 715 rubles 7. SCT oil filter – 121 rubles 8. Suppressor – -54 rubles 9. Tensioner shoe – 45 rubles 10. Pins – 160 rubles. But I took the wrong ones. I need from 2108... 11. AMP valves (Poland) - 900 rubles 12. AvtoVAZ 2101 guides - 270 rubles 13. AvtoVAZ rockers - 850 rubles 14. AvtoVAZ camshaft bed - 400 rubles 15. Mandrel for rings - 250 rubles 16. Countersinks - 900 rubles 17. Retaining rings, gearbox bolt, ratchet nut – 200 rubles Looks like I didn’t miss anything = ) ) )
Tuning the VAZ-2107 engine
The internal characteristics of the “Seven”, which are responsible for the car’s performance and its normal operation, often require improvement.
The standard engine power of the VAZ-2107 is not particularly high. You can easily check this in the technical passport of the car itself. By tuning this element, you can easily and without much effort, time and money make your car better. The resources and characteristics of the converted engine will be much higher than the factory ones. It should be taken into account that before starting work, you need to decide what qualities you want to get at the finish line, because any upgrade is carried out strictly individually, for yourself.
Refinement of the engine can be aimed both at improving power and at tuning its operation, adjusting existing gas distribution phases, and more. Modification of the VAZ "Seven" may include tuning of the cylinders (choosing a suitable crankshaft, boring, choosing the correct balancing of the pistons), sometimes it is necessary to install a compressor or turbine (turbocharging tuning), tuning the intake and exhaust. For a car enthusiast, you need to determine what kind of engine power you want (upper or lower).
Tuning a VAZ-2107 engine with your own hands is, whatever one may say, a troublesome task, and you need to understand the technology very well. But when it is not possible to contact a specialist or there are no specific skills and knowledge, a simple and no less effective option is possible: replace the engine itself. It is better not to change the displacement of the standard engine (in the “Seven” it is 1800 cm³). When replacing an engine with a new one at home, the engine elements such as the cylinder head, cylinder block, connecting rods and crankshaft are of interest. The ideal “donor engine” for modification can be called the new engine 21213.
Lightweight valves
Installing lighter than standard valves ensures that the valve closes quickly with a spring. For this purpose, expensive light alloy valves are used. This method of modernization provides greater efficiency and normalization of valve timing at high speeds.
When tuning valves, you can install upgraded valves with a special shape of the disc profile.
Sometimes, instead of using light alloy valves, the valve plates are simply lightened. Less weight requires less camshaft effort to operate. Reduced weight rockers can be used in conjunction with lightweight valves. This will give even more advantages when using the machine at high speeds.
A similar effect can be achieved by installing more powerful valve springs. The valves also begin to close more quickly, but this solution has its drawback: stronger springs place additional stress on the camshaft, reducing its durability.
VAZ-2107 suspension upgrade
Tuning the VAZ-2107 suspension is done in the same way as for the VAZ-2105 or any other model from this category of car. The selection of those parameters that require replacement is carried out in accordance with the wishes of the vehicle owner. Most often these are springs, ball joints, shock absorbers and anti-roll bars. The sports suspension for this car will be more rigid, and with it, driving will become more reliable and safe. The most common option for modifying the suspension is replacing springs (springs from Niva are taken) and replacing tires and wheels. This creates a sports suspension. The decision to change the suspension removes the question of how to raise the Seven. Tuning the chassis of this car, as you can clearly see, is very useful.
External tuning of VAZ "Seven"
External tuning of VAZ is performed most often. The second most popular upgrade for the VAZ-2107 is interior tuning, which was already discussed above. External modifications bring great pleasure to car owners, since a beautiful picture will always please the eye and can become the highlight of the owner. The main thing is to give free rein to your imagination. The range is quite wide: from painting to replacing headlights. There is no point in touching on the topic of repainting a car or applying drawings or stickers to the body, since it is very simple and does not require special skills.
Tuning VAZ-2107 headlights requires selecting the LEDs you like, a drill, sealant, a panel for the headlights, resistors and connecting conductors.
First of all, you need to select the size of the panel for the headlights in accordance with their parameters. Then the drill comes into play. You need to make several holes at the same distance to install the LEDs, which subsequently need to be connected to each other using contact wires (plus to plus, and minus to minus). Assembled circuits of LEDs are connected to the headlight power supply blocks. For every 4 LEDs, a resistor is needed to provide resistance in the circuit.
The beginning of chip tuning
The result of injector chip tuning is not only a change in the dynamic characteristics of the car, but also an extension of the service life of the power system and cylinder-piston group. All changes must be carried out on a fully functional car, since in the presence of technical faults it becomes difficult to obtain the desired result from tuning.
Chip tuning must begin with the selection of software. Sources of the necessary software can be:
- Developments of tuning service centers. The average car owner often does not have access to these programs, so to flash the module you will need to contact a specialized studio;
- Openly available software created by other car owners. This method of chip tuning should be treated with caution, since most software is not tested for its effect on the engine, which can quickly damage it or worsen its dynamic characteristics;
- Write the execution code yourself. This option is suitable only for car enthusiasts who understand programming and have the ability to control engine parameters upon completion of tuning.
If there is insufficient knowledge and lack of software, the quality of which the car owner is confident, it is better to trust the modernization to specialized workshops. Although chip tuning is a reversible operation, operating a car with incorrect software can significantly reduce the life of the power plant and fuel system.
