i just put a sts rear mount on my ta with a gt-67. I am going to dyno it this wednesday coming up. I will let you know. I am pretty sure it will put out over 600 easy. I am running around 12 lbs. of boost and raced my friend who has a 02 zo6 with long tubes, corsa exhaust, ls1 edit, vararam, and a 200 shot of nitrous which is the nx nixel system. He jumped me by two cars right of and by the time it was done i was 2-3 cars ahead. He thinks he is putting around 580 plus. but who knows. I am going to raise the boost to around 18. Another guy here has a turbo tech kit and his 60-1 would not make more power with more boost. He called george at turbo tech who made the kit and he said the kit was made for low boost and that the log manifold will not flow very well over 10 and cause alot of back pressure and heat. on the sts kit i am using longtube headers which flow alot better than a log manifold.

I'm running lunati NHRA flat tops.
amacgt. I think your right about the high back pressure but i've spent alot of time on the phone with george and He don't think i'm at the limit of the manifold yet so i guess well see when i get the new turbo.

from what i've seen so far 8 psi on a 67 should yeild aroud 500 rwhp. The one 67 STS car here will be trapping 120+ on 5psi in winter time. Thats pretty crazy power for such low boost. 8 psi with some water alky, good gas and more timing should be a real blast

I just wish I owned an F-body so that I could run this setup since it seems to be quite cost effective. You must upgrade your fuel system and be tuned well though.

I'll have to live with my 89 supra for now, i'll be happy if i can make 600 rwhp.

Just imagine what a 454 and a 101mm turbo would be like
