Hey these are not Nissan turbos, oil change at 5000km, just like Evos.
and engine oil cooler using an old Magna/Starion cooler.
Match does have a good intercooler remember, these things count.
My car has been running at 19psi for a long time now. It's been around the track and generally gets thrashed and I haven't killed my turbos! Above 14 or 15psi they do lose efficiency, but who cares? It's all about power!
