IF you don't have these done yet then get these 1st.

1. An aftermarket clutch cause nothing is worst then not being able to put the power down.
2. A lightened flywheel (8lb flywheels give the B16 more torque, cause B16s suck at that).
3. GSR Cams (less than $80 & are plentiful); good for 4 WHP
4. And the other BASIC bolt-ons if you don't have them yet. Intake, hi flow cat, 2.5" exhaust and a 4-1 header w/ 2.5" collector will do just fine.
