Ok how much money do you have to spend? If you want to beat the trans am for the cheapest amount of money then I'd get NOS. $500=100hp=$5 per hp can't beat that. If you want to stay N/A go with
Gears, I'd recomend 4:10's for your AUTO, probably run you from $400-500 to buy them and have them installed.
Pullies, about $50 give you from 5-10hp and real easy to install although if you live somewhere that it get's real hot(like tx) be careful about cooling problems.
Yank your airsilencer and buy a K&N or get a ram air setup, for the K&N it's about $50 and should get you another 5hp.
Again if you could give us an idea of how much money you have to spend I could make some better suggestions. Oh and if you really want to smoke him, get the gears, pullies, K&N AND the NOS.
