Mike,
If you're talking about this turbo, the specs look like just a 76GTS. (S-trim F1 wheel). Maybe Jack can chime in as he's a turbonetics dealer.
The 76GTS from PTE rated a 1100hp. and the Gt4276 at 1200hp. I think both figures are slightly high.
I swore that supra guys were making 1000+ to the wheels with the GT42's 74mm version.
