Hello!
This is a small log of my car. I apologize for my English, I do not have much practice.
For 10 years I drove Evo4, Mazdaspeed3, Mazdaspeed6, Evo8, Evo7, EvoX.
3 years ago I wanted a more practical car, but I did not want to lose much fun. And I bought my first BMW. It was 2008 X6 50i.
For 2 years of ownership, I repaired the engine, install downpipes, flashed stage2, installed front and rear from X6M (it has 3.91 gear ratio vs 3.64 on 50i), cooling system from X6M, X6M brakes, XHP software to gearbox.
But the car was not fast enough. Best 0-60 was 4.9sec, 1/4 mile was 13.3sec
