Gradenko: Not too much since I'm just looking to learn how to work on the rb motors. I've already put a turbo timer and a hks exhaust on it. Looking for an intercooler and boost controller (probably greddy profec B). Changing the plugs soon but so many different opinions and I don't know what's in there right now. I checked the NGK catalog and it says 5 but then some people say 6. I don't know if to go platinum or iridium, heat range 5 or 6? I've searched many threads but still indecisive.
Madgt4: Wow, that does sound pretty large? Are you going to have too much pressure loss in that i/c? I guess that depends how efficient it is.
Steve: No, I'm not upgrading any turbos or anything. I'll probably be purchasing hks2530's from what I have read later for the R33gtr or R34gtr.
Thanks for all the advice, I'm just looking to upgrade a little and learn on this car before I purchase my R33gtr or R34gtr next year.
Anymore advice would be great. And yes, I haven't been posting much because I've been searching and reading through everything first.
