Tuning, Technical Questions
Hi all,
Firstly, apologies if this is answered elsewhere but I've been trawling round a bit and can't find a definite answer.
I have 2 turbos for my R33 GTST series 1...
1 - the original stock R33 GTST (removed)
2 - an R34 GTT NEO turbo with steel internals (fitted)
my question is what is it...
