When I've bought my MK4 it was already "singled" with SARD turbo kit: KKK K27 turbo + 3470MOJ compressor. It's all I know about this turbo as yet Can't find any deeper details till now. It seems to me that this is not very common turbo for 2JZ. All I've found is small video on youtube with Ridox Supra having exactly the same turbo setup (http://www.youtube.com/watch?v=Vu_pyi8j0N0)
Currently it starts to produce small positive boost at ~3100...3200rpm and reaches my "boost controlled" 1.2bar at ~ 3800...4000rpm. Timing is ~10deg at 1.2bar, hi-rpms (not knock-tuned, just to be on safe side).
The questions I have for now:
1) Is it OK turbo for ~600+bhp?
2) How laggy is this turbo in your opinion (compared to other, well known T60-1, GT35 etc...)?
3) What is the best T3 turbo for my goals [1]?
Thanks.
