It all depends on what you want. If you JUST want power, then get juice or save for a superchager
IF you want a quick car, get gears.
I'd suggest an FIPK, TB, Plenum, Mac Prochamber, catback, and maybe an SCT Microtuner (this would allow you to tune for everything, advance the timing, etc....).
If you wanna stay N/A, get some Stage 2 heads, and VT or Comp cams
