lol, ok if you want to modify a probe, here is a good site to help you out, and what to start with...

they have alot of good info. if you really want to mod. your car, look into the klze swap, i am not sure on how much you want to put into this car, but if your looking at over 5k, i would def get the klze engine, especially if your current engine is having any problems/or is old. any way, don't go for the cheap stuff off ebay, it's junk. beleive me, it may look like it is a good deal, but there is a reason they are selling a chip for $7 that claims it will give you 15+ hp. want to know the reason? IT IS BS! if you want to mod your car, DO IT RIGHT! beleive me from experience, any way ive rambled on long enough, good luck! oh if you want one of those mufflers, that say they will give you about 10 hp, ill sell you mine. i never installed it or anything, because it will require more work then i wanted to put into it, but there all the same so if you want one, just let me know, ill sell it cheap.
