Intake, exhaust and header would be a good start. Cams and a vafc would be a good idea next. That should get you pretty close to where you want to be depending on how aggressive the cams are and how they are tuned. A valvetrain upgrade with stiffer springs will be a good idea depending on the cam choice. You could also upgrade your intake manifold.
Keep in mind that I am a turbo guy, so I don't really know much beside basic bolt ons for a N/A setup.
I have a turbo GSR. If you click on the link in my signature, it will show you pics and list my mods.
