I am from the U.S. and I don't have much information on these engines in particular because they never were sold here.
I am looking for help from you experienced rb20 experts out there. What levels of boost would you say is it neccessary to switch to a metal head gasket? And when will I have to start worrying about the bottom end?
My current setup is:
FMIC
14lbs of boost
Some turbo I still haven't identified(non ceramic)
Custom 3" exhaust
Walbro Fuel Pump
z32 Maf
Chipped Ecu
And I know the stock injectors should be on my next upgrade list. Along with a reprogram for my ecu. Anything I am missing?
Thanks in advance,
Slick
