Its a 92 trim that we have been using which is basically a 91 with a larger housing. Switching over to the Rotrex is not as complicated as you make it seem since we have been testing it on our other car for awhile now. Not to mention we have had a supercharger kit for the E9X M3 for about 4 years.
You should see a little more power from the stage 1 when on stock sized wheels but the stage 2 is spot on.
Are you supercharged?
