Downpipe, tune and FMIC gets the N54 twin turbo I6 to 400whp+. The M2 has the N55 single turbo. Makes less power with modifications. The M2 competition has the same S55 twin turbo engine as any M3. Downpipes and tune gets them 500whp+Didn't know know, EVERY BMW I6 has "400 whp with just a downpipe and tune"
Guy in the office next to me has a VR4. He put DR500 turbos on it along with some E85 and turned up the boost. A couple months later we went to lunch and could hear a decent tapping noise at idle. Sounded like something in the bottom end, but the car still ran awesome. He finally dropped the oil pan only to find a bent/twisted rod. It was bent just enough that the piston twisted in the cylinder allowing the skirt to tap the inside of the block. He got lucky as it could have been a lot worse. Here's a picture of the piston and rod assembly on my desk. He is now built and makes more than 500whp with the same turbos.Not a BMW, but I knew a guy with a Mitsubishi VR4. That thing spent more time on trailers/lifts than it ever did on the road. I used to challenge him all the time to a 500 mile endurance race...in my base model Sentra
