Stage 2 TT T3 would be my call then Mike having had a NMS Gunship map on mine, ok it dies top end but they're a cracking little turbo, or a T34.48, again, quick spool but too end loss.

I agree with Jay, all dependant on your driving style and what you want to use the car for, have you got APs or other brake conversion on your car Mike?? What clutch, inter cooler, injectors too??
