what have you done to increase HP???

Intake, 2.5" test pipe, muffler, magnecore wires, bosch plugs...It's not much, and my car is still slow as piss. If you're interested in just what you can do with a 4g64 check out this website. Goodluck.

you can also wrap the header and intake. keeping the heat inside the header lets the exhaust flow quicker, and cooler air in the intake helps alot too.
