Is there any way to pull off 500 hp from a bmw engine? I know they aren't to adaptable to blowing so I was wondering what internal modifications needed to be done to get high hp gains. Any help would be great thanx

hope you have a super sized wallet power in a bimmer doesn't come cheap. The closest I could recomend it to get an ///M3 and go over to dinan or hamman. You would need software, exhaust yada yada yada. what are you going to use the car for? I think Hamman took an M5 engine out and put it in a M3 Thats a 400hp base and dinan has a 470hp m5 package. Either way tou are looking at a HUGE amount if MONEY

I saw M3 on a site that was 500hp, cant remember the site though...

I think a current gen. M3 with a big enough turbo could pull 500. Of course, turbocharging that engine would be insanely expensive...
