I dunno if I posted this before or not but... My buddy has a e36 m3 with the 3.2 m power swap (eurospec motor) and he has problems getting traction on his BGF G forces just with headers, exhaust, intake and tuned engine. AND the vanos is wayyyy off and it runs like hell. So I would definatly go turbo because that car has plenty of pickup with just simple mods. Even with what he has hell race damn near anyone within reason. And the way his valve timing is currently hell still run from the blue lights... I know Ive been with him when hes done it....
