I wished stuff like this would be more affordable here in Germany.

but the difficulty to find parts, the TÜV, gas prices, insurance and taxes make it realy hard to build a proper turboed BMW.

its not impossible, some guy I know has a 800 whp E30, but its expensive as hell.

The money you can put into things like this is often better invested in upper class cars like Porsche etc.

you guys are lucky
