So I just picked a 2002 P5 with low miles as a new project and am looking for a little info on the transmission. The ultimate plan is to turbo the car. I plan on getting a Fidanza 7lb flywheel, SPEC stage 2+ clutch, and I already have a TWM short throw in there. From what I've heard, however, is that the G-series transmissions don't hold up very well to boost, and that it won't hold more than 200lb/tq before exploding everywhere (exaggeration). I have also heard that the weak links are 3rd and 4th gear; and by replacing said gears with, for example, Par straight cut gears, that I should be able to run near 295lb/tq. Now these are just numbers I've heard being thrown around. Wondering if any of you have had experience with G-series failiure under boost or have experience with replacing gears for better tolerance?
