2001 AR5 Swap, Built NA-T, Standalone
Honestly, just do bushings and handling stuff before anything crazy. From my anecdotal experience, I installed BC 264's and a Titan cam gear on my car with intake, header, full exhaust and GReddy EMU (lol) and only ran .001 sec faster. I also tried revving it to around 7200 with no help. My fastest 1/4 mile was 15.397 at 90.63 mph lol.
