Ok... impulling a 3.1 on saturday and im going to build the shit out of it. the guy that is helping me says with a large enough turbo (17c syclone/typhoon turbo) and some new compnents, i can hit the 500hp mark easy.
The problem is the tranny. I know the 4T60E will come apart at about 250hp at the most. I would like to keep an auto tranny in the car, but dont know whatis strong enough and compatable to the 3.1. I could go with a 5-speed conversion bu that means swapping dash and seats (mine has a bench seat and colum shifter) and i would have to find a way to get a center console in there, which if worst case scenario, i can do. money is kinda tight though so i want to keep it as inexpensive as i can.
Are any of the newer trannys from say an early GTP, or even a later GTP somewhat compatable??? Any suggestions??? How much hp can the stock TGP tranny carry???
Any help would be awesome
