You should be looking at 60-70mm comp wheel turbos( and down on the lower side)..how bought a precision 6766? I would have thought in a T4 frame it has enough snort for mid 9's still, or if you want high 9's PT 6262, bit more snort than a 3540 , or even a 3540 will scrape in 9.9's..lol Thank god your in this thread. Might end up with a 101mm on it otherwise, bigger is better right Some original photos have not been recovered yet.

i am not suprised a GTX 42 would make 1000rwhp..a GT4202 with a 78mm GT4508 comp wheel will get there and they have around the same flow, just a 78 would be laggier as its a bigger and heavier wheel. PT used to make them as PT78GTS..In the end backpressure would be the killer, it would be 80mm turbine time cheers darren

Id also talk to Paul (GAS747)... He had a T51R on his car and scrapped it and went the GT42r and made more power.
