I have car type list, if i put in on Type 1 i can put engines what i wanna, if i put on 3,4,5 it can be only 2000ccm max.

Every car in LFS is divided into car type classes, which also have their limitations and specifications. These include weight, power, turbo power, torque and idle rpm. In limitations there are ones like minimum and maximum amount of gears the car type class can have, maximum engine size and the amount of cylinders.

With the use of a right tweaker you can alter these limitations to overcome them and have a 12 litre V12 engine in an XFG.

And the last, somehow when i change air resistance it changes only my kmh speedometer. .

Air resistance is basically what slows the car down at higher speeds, when you remove it the game thinks your car has a giant top speed regardless of the power. I have no idea how the power values work, but I've noticed that smaller values sometimes increase the overall power. If you can't figure it out, it's best to just get power with the use of a lag-less turbine and tweak it's pressure for wanted power.

I'm in

Would love to get the license, i think I'll spend much more time in this game if i'd get it, not that I'm not spending a good deal of time right now
