T4
I would be a toss up. Jose would probably say the S400-80 with 87mm turbine = SX80, but I'd be more inclined to say the PT8847, with GT47-88mm comp wheel and 92mm turbine, though the small housings cut the power. I think it would be fun to see both on the dyno. The Borg would be alot cheaper.

Yes the GT47 is a bad ****, and much better suited to a larger motor then a SX80 would be. Lag would be the difference though...
