well, a free flowing exhaust would no doubt help, and possibly an uprated air filter, and/or induction kit. A remap of the ECU could possibly help as well.

If you're looking for a really big power increase then you could get a turbo kit, but then if you were doing that, it would make more sense to either get a WRX or drop a WRX engine in the sport.
