Depends on the kit. Most of the kits come pretty complete, so you don't need much else. However, you might consider exhaust and possibly an different air-meter. My car didn't really come alive until I dropped the 3.73 gears in it.
Also, be very aware of your fuel system. The stock fuel system is anemic at best. You'll want to step up your injectors to a MINIMUM of 30# and replace your intank pump with a Walbro 255lph or equivilent. Also, the pickup in your tank has an 1/8 check-valve. Ever try to breath through a straw??? Get that fixed while you're at it.
Get the car dynoed using an air/fuel meter to be sure you're not leaning out. Have someone who knows what they're listening for check for detonation.
Good luck!
