depends if you have an auto or a 5spd... if you have an auto... lol negative. =) mine's dying now at only 10psi from a T60-1 turbo... i'm putting in a sound performance built transmission and torque convertor, i've heard nothing but raves about them. there are other solutions, such as level 10 and other places also. expect to pay around $3500 for everything, but once its in, it'll last!

I was wondering how much did the whole setup cost you and how much HP are you getting out of it with the T60 turbo

Talk to Larry at SP about their auto tranny upgrade for the 4spd in the coupe. In stock form, it only holds around 300hp, perhaps a wee bit more. The SP upgrade is around $3k and is good for 500+hp. Even a "tame" T60-1 will spin out over 400RWHP, as we can attest. The Level 10 tranny is lame, many people have problems with thier upgraded tranny. Ideally, a 60-1 would make over 460rwhp with 22psi. I'm at 10psi on stock compression, which translates to 15psi if using the low compression gasket. Calculators estimate around 400rwhp at this setting.

22lbs is pushing the ragged edge of efficiency on the 60-1, it just can't move much more air than that...

I'm looking for more flow on my system as a 12.7ET is starting to feel slow... I'm just getting used to it. I'll probably look at upgrading my turbo by sending it in to SP. They can work magic on most turbos, with hand machining, polishing, porting, clipping, etc. I'll probably swap out a higher A/R wheel as well.

The Toyomoto and SP kits end up around $6k without installation, and include basic intercooler, electronics and T60-1 or similar turbo.
