Cheap HP gains....
1. Lighten the car, rip off smog equipment, A/C, ditch spare tire , real fanatics pull speakers and headliners/ overhead /center consoles, back seat. You choose how light u wanna go
2.Pull honey comb out of MASS airflow sensor.
3. Make a home made ram air kit with milk jugs and aluminuim dryer pipe and a old intake snorkel off a carburated GM car. Mount the snorkel where your air dam is under the front bumper (mind you need the air damn to help cool your radiator so only cut off about a foot of it)
4. BOSCH +4 or +2 plugs, yes they really help.
5.. K & N Yes it helps
6. Ignition module, coil, and new wires.
7. Run synthetic oil if it does not leek out of your car ( good for at least 5 HP and u can leave it in for 6-8k miles).
8. Punch out the ceramic in your Cat.
7. Replace stock crossflow with cherry bomb
8. Throttle body spacer
8. Gasket match and or port TB, spacer, and intake, if you really have alot of time and skill, gasket match your intake toyou heads, and your exuast mani's/headers.
9. since u eliminated your A/C and smog pump, pull your PS pumb belt when you are sure your gunna be racing ( need to get old 86 or older non serpentine pullies, if you order new migh as well get the underdrive kit.
10. CHIP!
11. Now its gunna get spendy, and I am leaving work so im out, l8r
