u running with an auto transmission or a manual?..If you're wanting this thing to be somewhat fast you'll need new gears too
Underdrive pullies are a good mod for the money too.
Honestly I'd make sure and make it look nice..Get some chrome wheels too

its an auto and it looks pretty good right now it has the pony package so it has the wheels and everything im basicly looking for the ebst bang for my buck kinda things making it somewhat fast

You'll need 4.10 gears
and get a full dual exhaust system (long tube headers, & the mufflers of your choice) and a cold air

dz beat me to it. 4.10s for the Auto. but don't go longtubes, the stock manifolds are good enough until about 225 whp. a stock v6 has between 155-175 whp depending on tranny and some other factors. what you need is to let the car breathe easier, cause right now it is like breathing through a straw. 1.8 roller rockers, mass-air, 70mm TB, and some other minor stuff should help.
