Depends if u want to stay all mtr or not.
*if u want to stay all mtr, there are several different headers from 300 to like 1200.
*a cheap upgrade ppl do is GSR cams, i think vteckidd has a few sets left for dirt cheap.
*a cold air intake (with by-pass valve) if u dnt know how to drive in the rain. lol!!!
or u can get the j's racing or password jdm carbon fiber intake.
*lightweight flywheel is a pretty good and noticable mod.
*custom exhaust (madrel bent 2 1/4- 2 1/2) or a good catback setup.


that is a pretty good start for a na setup IMO. vteckidd will be here soon, lets see what he has to say. Damn NA punk. lol!!

Im more into turbo B-series right now though, NA is later.
