ok, so i have a 2001 tib with cia, header, exedy clutch, and exhaust. im not real big on forced induction on a stock n/a motor. too much $$$ so are their any other upgrades that i can do that dont cost an arm and leg and also dont involve me reworking my ecu? i was thinking about a cam but ive heard alot of people complaning about ecu problems with new cams. and the only intake manifold i can find is like 650$ and ive heard that doesent really do anything. im feeling kinda stuck. anyone have any ideas? thanks.
