hiya, ive since taken the turbo off the B, but at the time.
0.60 times i couldn't be precise but it would be 2-3 car lengths ahead of a 260bhp sabb aero. if that helps.
Top speed would be around 140mph as i was told by the previous owner he had managed that. I never got the chance but believe that would be easily achievable.
Max torque was 155 ft-lb around 4000 revs and 188.8 bhp
All i can say is that it was very quick and great fun.
I might consider selling the kit, if one is interested.
