yeah, do the swap.

Intake 60-100 bucks.
Header 200 bucks, used dc-sports
exhaust ~300 bucks, used, or custom bent, whatevs.

You can do those in stages, and you're probably looking at ~120ish HP in a VERY light car.

I'd want to do some suspension work too... I dunno, my hatch is so light, that I want to be a little closer to the ground, hehehe.
