Jeez, don't go spending money where you don't need it. Trust me, I tried it and it didn't work. 1st off, depends if your car has the 4g63 they did make some non turbo, or the 420a engine. Both may be turbocharged if they aren't already, and that will give you the most important bang for your buck. Cheap mods like chips, cam gears, etc. will only give your car power in an area that it lacks in, like timing issues when you change cams, or shift points when your power band changes. It depends on how far you want to go with performance. If you are looking at a light bump in hp, freeing up intake and exhaust with a cold air intake and cat back exhaust will assist. don't for any reason change the intake if you are not going to change either internals or the cam. it'll do you no good. Sure, you will make awesome power in the three 8K rpm range, but what could happen if your car still redlines at 6K? If you are really looking for some power, think about tearing the motor down, building up the bottom end with some pretty radical dished pistons, throw a bad turbo on there, run cam, headers, intake, and throw about a 50 100 shot of nitrous on there if you have built the bottom end well enough. Also ditch the auto if your car has one. five speeds seem to have much better reliabilty. Good luck with your car and hope this helps.
