Hmmmmm, if you're gonna get rid of it anyways, NOS all the way! If you might keep it as a project car, it might be worth it to turbo or super charge it. Depending on how long you want to keep it, there are a lot of moderatly cheap upgrades that'll get you a little performance out of it. Best ways to get power without forced induction are exhaust, headers, Cold Air Intake(referred to as CAI), hi-flow catalytic converter, and if you really want power, some Type R or NOS stickers! Somebody correct me if I'm wrong, but those two stickers alone could give you around 50 HP
