anything is possible, probably have to be alot of custom work though, which means quite a bit of $$$$.
Things you could do
Get more air in
-get rid of airbox, slap on a k&N filter, extend it down far and add a scoupe for ram air, take ur throttle body to a machine shop and get it bored out a bit
-get air out faster, slighty bigger piping, free flowing car, less restrictive muffler
-more spark, upgraded coil, spark plug wires wit less resistance, spark plugs that give more spark (silver the best conductor)
-more fuel, raise fuel pressure with a adjustable fuel pressure regulator, bigger fuel pump
-less weight, the lighter ur car the faster it will go, depends how far u wanna go with that
-light rims and lighter disc brakes for quicker acceleration
-upgrade the computer, new prom chip?
-reroute ur belts to leave out the ac
-get it to run as cooler, lower temp thermostat, full rad flush, 50-50 mix of good coolant and distilled water. Synethetic oil also stays cooler than regular oil, royal purple oil will get u some hp.
-make a custom grounding kit
if you really wanna go crazy, get ur engine rebuilt tough along wit the tranny, get a custom fabbed turbo or supercharger kit
you'll have a pretty quick car after all that
hope you win the lottery soon
