I'm looking into buying a stage 2 turbo kit from star performance.
What else should I get in order for my car to run properly?

EGT gauge, and a Corbin or Jumptronix A/F meter.

An inline pump to augment the intank pump will help.

Out of the box, the kit is usually fairly complete. keep the boost low, and you'll be fine.

If you don't have one already, a nice 2.5-3" cat-back exhaust would be very helpfull. With what Darkone said and the cat-back, you should be all set!
