Surf around in TechInfo, There'* another one called "First Performance Mods"

Like Dame said, those articles are the place to start. If you're looking for vendors there are many good ones at the bottom of the link he gave you. I'll paste 'em here for you.

alot of Grand Prix stuff can be modified to fit our cars

You'll never regret getting some window tint and rims.. No one can say **** about either..

The best bang for your buck is probably 1.9 rockers. INTENSE currently has a sale going on them but if you decide to do them I recommend upgrading springs, retainers and using oil-restricted pushrods

180 T-stat, 1 step cooler plugs, and an air intake are a good place to start.

thanks for the reply guys i already have sum tints and a decent system and sum video entertainment for my joyriding :P but theres more im looking into..... performance and visual wise i really want the clear corners not to sure where to find those either :? anyways thanks for pointing me in a direction to start
