My uncle told me that you can't turbo a E46 M3 but you can put twin turbo in E36 M3 and I was saying you can only put a single turbo inside a E36 and that you could also put a single turbo inside a E46. Could anyone help us settle this? Thanks

The E46 is theoretically capable of a turbo charger, just nobody has done it yet that I have seen. There has been hints that Active Autowerke is planning one for next year, but nothing definitive yet.

I have heard of a Twin Turbo E36 M3, and I'm presently searching google for one, i'll fill you in later.

thank u
