I Have A 92 Z28 With L98 Engine. I Installed Accel 22 Pounds Injectors. What Else Can I Install That Is Not Too Expensive But Gives Extra Power.

Thanks

You also should upgrade the ignition system, K&N air filters, SLP/Accell/S&M runners and base, port the plennum

These cost a little bit of money, but they are the big gains: new heads, a cam...

 

Before You think about adding mods.... Make sure Your car is in proper tune. How long has it been since Your spark plug, wires, cap and rotor, fuel filter, and O2 sensor have been changed? Once those are all up to par... You can do simple free mods like bypassing the throttle body coolant hose and advacing Your timing. If Your handy with a die grinder, You can port Your plenum which is located behind the throttle body. Look at all the small things that will all add up and make the difference between a slouch and a good runner.
