The only thing that would be a factor is the longer gearing in the G20T gearbox. You'll need to redline every gear, otherwise you'll drop out of the crossover. My boy has a P11 trans in a B14 and he was disappointed in his recent runs. The gearing might hurt you, but power/tq wise, I think you'll get him. Hopefully, you shut him down on the track though. Just my 2 cents.
