That's good info you've gotten so far. The absolute best thing for you to do right now is figure out where you want to go with the car. Many of the mods you could get, 2 1/2" exhaust, bigger MAF (I like the C&L), bigger throttle body and so forth sound cool, but they will actually hurt you unless you upgrade the entire system, ie intake, heads, cam. And that is where you get into the big money. The pullies and gears are a great start. If your patient the best way to go after that would be to work on your suspension, springs, shocks, upper and lower control arms and sub frame connectors. This will give you a great base to work from and by the time your done you should have a better idea of what you want to do with the motor. Another great investment is a good set of tires, I like the Nitto Drag Radials. Like gtsr515 said the last thing you need to think about right now is biger injectors. The 19# injectors are good to roughly 300hp at the stock fuel pressure and can be used with more hp with an adjustable fuel pressure regulator. Good luck with your 89, send me a pm if you have any other questions.
