what to buy next?

here's what ive got so far; high flow muffler, high flow cat, and cold air intake, ive got an 89 2.0. i was thinking about gettin my heads ported and polished, i was told that with the things i already have that i would see a pretty big difference after porting and polishing. ive found headers that would work but they cost like 500$.

how much gain would i see with my heads port and polished?

maybe about 5%. the way the head it set up there is a "j" shape on the inside so you'd only really gain the top for flow. try checking out pacesetter for a header (mine was only like $150).

i agree go with pacescetter thats wut i got and u can feel the difference.
