HP Gain

can anyone tell me of any cheap or free ways to improve hp or preformance in my 99 zx2

intake, Underdrive pully, thats good for about 8hp and will cost about $120

K&N filter, $45-50
thats the cheap stuff.

Keman Intake modification, basically remove the upper resonator, recangular peice near the throttle body, and then if you remove you intake, it says air filter on it, you can then remove the lower resonator.

Thats to take the intake and route it through the fender.

You can use exhaust piping or pvc to replace the upper.

not it looks like shit :) hence why i said intake :)

True, but you can still run an intake and then remove the lower resonator at least for better airflow. And i doubt that if hes looking for cheap mods that hes gonna care what it looks like under the hood.
