1000000 mph lol only joking it goes 137 mph
yes, but you would have to get an m3 subframe to go with it...LOTS of $$$
The M3, M5 and M6 are all limited to 155MPH. However, if the limiter is removed, the top speed exceeds 200MPH.
The top speed depends on a couple of things: Which M3? Stock tires or aftermarket? Is the car electronic limiter taken off? If you are talking about straight out of the factory all of the M3's are limited to 155mph. The new M3 aka 2008 can achieve a top speed of 203 mph however once it has been delimited.
All bmw's (U.S. spec)have a limited top speed of 250 kph (155 mph), only exceptions are v8 M3 limited to 161mph and Alpina's. Alpina (a company like Saleen/roush is for fords) sells the B7 a modified 750i no limiter will go 189mph, but still has a warranty and is serviced at BMW dealers.
You will need to open the hood with the lever and then go to the front. Make sure it is securely opened before looking around.
