lots of info on the r31skyline club about turbocharging the rb30e engine from using basic vlt ecu/injectors/manifold/turbo thru to cam changes, ecu upgrades etc etc many guys are making 400+ reliable rwhp from original, internaly standard rb30e motors with cam and valve spring upgrades. my ti has original 300,000ks and 350rwhp and been turbo'd for around 7yrs
