h/c/i rear suspension(torq box weld, subframe connectors, upper lower control arms, weld axel tubes) gears, tune, injectors, and mass air meter. if you shop around locally you can probable get some good parts at a good price (people will sell for about any price when bills are piling up) oh and dont forget full exhaust with headers long preferred but short tubes will work. and think about where you are and where you wanna be, that means dont just buy parts for now buy them in mind to support future upgrades
