Default Want Performance On A 89. . .

I Have An 89 Convertible, 105k, High Flow Cat, Dual Flowmasters, Accel Coil, K&n Air Filter, & High Flow Oil Pump. What Can I Add To Increase Horsepower Without Spending An Arm And A Leg? What Have You Done?

Are you handy with a die grinder?

Vader's site has a bunch of good info.

Not much more you can do..without getting into the engine and spending money....you can add headers though if you havent yet.Maybe 1.6 roller rockers.Higher stall torque converter if an automatic or better rear gears if you have less than 3.07's.Those arent that cheap either.Those will cost a few grand all together if you pay someone to do all the work.
