Hey guys, I have an 02 2.5rs and wanting to know some info on how to gain more power traveling in high rpms. with out boost. I mean if I had 3k to get the avo kit I would boost but so far I've read people getting delta cams but never did extensive research on it. time isnt really on my side anymore unless I make it and that's still rare. just wanting some help to gain some hp with out spending big bucks. thanks
ps its basically stock except tsudo cat back and going back to stock air box.
