Had some adventures with my '87 Lada 2108.
I had some free time, so I decided to clean the engine a bit as it was covered with oil+mud/dust. And I have even found some marking on the engine block under the mud. I used to think that I had a 1300cc engine (documents said that too) but it appeared that I have 1100cc engine.
Ok, I thought. I just want my car to drive me as cheap as possible. But I started digging the documentation about early models of my car and found something weird.
Originally, 1100cc models came with 4-speed gearbox, but I have 5-speed one
Ok, they both fit, so it is possible.
But that answer started another question: 4-speed gearbox originally came with 4.11 final drive, 5-speed gearbox had 3.7 or 3.9.
What final drive I have is a question, but it seems the way to find out is to take the gearbox off. I hope it won't happen soon. But it might explain why my car is sort of calm and thirsty.
