M3 Power

[mr_tw]

I own an M3 CSL and also a GTR (non-racecar) and i was wondering if it's possible to get a turbo or supercharger on the standard M3 and if not what it's power output is, I am also curious if anyone has put out a list of the Fully modded power ratings of cars, I found the one that lists cars that are 900 and more, but is there a list somewhere of the cars with less?

Thanks in advance for your time and assistance
