Step 1. Don't go WOT until you take care of EVERYTHING on this list... Valve springs, timing chain (port and inspect the timing cover/oil pump while it's off), plugs, wires, fuel pump (with hanger mods), hotwire kit, scan tool, PS valve cover breather bypass, trans cooler, flush ALL fluids including rear diff and brakes, new 60# injectors with matching chip, check upper PS A-arm bushing, weld crack in driver side header, port the turbo elbow, new Delco or Denso(only) 02 sensor, new Delco(only) PCV valve, quality adjustable fuel pressure regulator, new vacuum line check valves, replace ANY vacuum lines that will turn your fingers black, replace the 3 hoses on the wastegate circuit no matter what (keep the 'T' oriented correctly), replace the radiator if the bottom of it is clogged, remove the resistor out of the fan, replace the flexable MAF pipe with a hole in it with a solid unit, aftermarket boost gauge and temp gauge, and a full spring cleaning.
You'll notice that your stock GN will outrun every "11 second" car you come across on the street. THEN decide if you want to make it faster.
