For reals though, Intake/Header/Exhaust( I/H/E ), and get a good professional tune done to your ECU. then you car will pull harder.
If you want to get into the engine, Cams and retainers are a good internal upgrade. I am running Type-R Cams in my B16a2. They are a cheap upgrade path and will be a huge help in performance. If your not afraid of opening your transmission then putting in an LSD will also help with launches as well as handling overall. If you dont want to go this far, just get I/H/E and a Tune.
If you have check engine lights, obviously check the code then fix the issue.
