I wouldn't spend a single dollar on engine mods for that car unless you have a CLEAR direction on what you want to do.
Start researching suspension. No matter what route you pick for the motor, you get to keep the suspension. Also, a slow car that handles well is still a lot of fun to drive.
If it were me, I'd do the following :
1 - Convert to Ex/SI/GSR front brakes (
FastBrake Enterprises, LLC - Intro)
2 - EX/SI front swaybar setup (22mm bar from EX)
3 - SI rear swaybar (13mm - fun for street use, get ASR 22mm for track use)
4 - Front strut tower brace
5 - B&M Short Shifter
6 - Change Tranny Fluid
7 - Wheels and Tires (15" wheel, 195/55/15 or 205/50/15 tire)
8 - Shocks/Springs or Coilovers (really takes some research to determine whats best for your setup).
Items 1-6 will run you less than $600 *COMBINED* and make a more noticeable difference over *any* engine mod you can do for that price. And if you swap, the only thing I mentioned that you can't keep is the tranny fluid
