What!?! No 4 Speed?
I haven't heard of 904's in cars with that much power. I've heard of them being behind about 700 HP. Then again, maybe with turbo's, it would be different. I'm all about 904's, but I think you have too much power for one. Have you thought of a Powerglide?

No never thought about a power glide........I need 3 gears! 75% of its use will be on the street. I will be changing out my 3.91's to 2.76 or so if I can find them. I want to be somewhere around a 3.0 Gear or so with the 28" Tall tire. Boost likes a load and the taller gear ratio will help to carry the gear out longer before the shift.

My thought is that Turbo Power is not like NOS, very smooth transition from NA to Boosted Power. So the shock would not be there like a Radical NA Engine with the use of NOS.......

I guess I need to do some more research on the subject.
I will call Pro Trans in Lancaster tomorrow and see what they say.
