I for one, would preffer a Turbo B16 with a B16 tranny over a LS with a LS tranny going Turbo, i have 3 CLOSE friends who have Turbo B16's with B16 trannys, all stock B16 motors, UNTUNED, with Turbo kits, one on 10psi (12.7), 8psi (12.8) and 8 psi (13.2.) Obviously drivers do make a difference and different turbo setups as well, but from local Turbo LS's that i have seen and heard about, none have even came close to accomplishing these times unless they are BUILT and not stock (w/turbo) like these B16's, but thats my opinion and friends experiences, oh yeah, and one of them has tried a LS tranny on the turbo B16 setup and the LS tranny slowed him down tremendously....

But what i think would be a good idea for someone to try out, is doing a 4.4 Final Drive on an LS tranny with a turbo setup with some good hp and trq. numbers. It will be higher than a GSR tranny but I am sure someone has done it, just havent found any input on it yet... :-)
