ohkay..i was wondering how much of a difference you guys think this wood make...i currently have knsri and ebay n1 xhaust...i wanna get rrm bored throttle body, rrm ported intake, highflow cat, racing headers, lightwiehgt flywheel, rrm lightweight pulley and then a good tune at the end..then start building my custome turbo..but how much hp u think i wood get after all that witout the turbo...im hoping at least 150 on my 03 rally..180 wood b nice...lol
if you get a good tune even with out all that youll probably be pushing 130, with that id say over 150, but theres only one way to find out. do it haha
im in the process of doin it..i finsihed jus bout everythin to the exterior jus got my cf evo hood in now time to start makin her faster...lol
Honestly, the 4g94 doesn't respond all that great to bolt ons, and starting around 100whp doesn't really help. Now if it was a 4g64, 4g69, or something of that sort, you would see higher gains. I'm going to guesstimate about 20-30whp gain, if that(how aggressive of a tune are you shooting for?). After you build the turbo kit, however, those breathing mods and flywheel(I'm guessing you will upgrade the clutch at the same time) will make a big difference. You can get the intake manifold and throttle body ported at a nearby shop for quite a bit cheaper than you would from RRM. You might as well try and get the head port/polished while you are at it.
