I've been BPU for several years now doing HPDE/track days/time attack.
I will be building the head. GSC S1 or S2 cams, springs, retainers, seals.
My 94 JDM Supra is in need of a reliable, track worthy single turbo capable of 650whp on pump 94 octane
My goals are:
- Keeping heat down to a minimum
- Full boost by 4000rpm
- 650ish Whp on pump 94 octane
Which turbo? T3 or T4? What A/R ? Why?
Cast or tubular exhaust manifold?? Why?
