i went from a T34.55 on greens to a SCS Spec T38 on 72lb blacks live mapped by nms

seems as drivable as it was on the t34, but pulls alot harder and holds it alot better

i wouldnt bother with a t38 personally and just go for a gt30 - much better turbo and more or less the same price if you look about

Jay a GT30 turbo can be had for around 1k which is more or less what a T38 costs.

Mine is a GT3076r so a bit more money but the way i see it - its future proof as i will need to bring the rest of the spec up to scratch if im going to max the turbo out.

A t38 will be maxed out around 450-480 bhp whereas a GT30 will sit there comfortably with a lot more to go.
