My friend just got a 03 m3 smg, and he smoked my *** in my 06 298hp 6mt sedan .
Ive got a intake and plenum spacer. with 7500k miles

Im not talking illigal street racing im just talking about the performance of the m3 compared to the g or z

We didnt realy get a official race or run done, but top end he kept pulling away from me with out a prob.... I couldnt believe it!


Do I have any hope without being boosted?

High flow cats? ? tunning? ?

 

 

Please, not another of these threads. Bench racing is pointless.
