I have read enough posts from people that have done the turbos but ran into problems I decided not go this route. And really not a big fan of turbos-yes they are more efficent but they lack the soul and excitement of a hairy maxed out NA motor. That is the reason I traded my 335I for an M3. Also why I grabed a C63-the last the big NA motors from MB.
How much power is the stroked 3.7 L putting down at the wheels?
