I ran an RSX-S back in OCT '05 with my '93 se-r:
RSX: 2.278 60', 1000' 12.353, 1/4 14.737 @95.60
Me: 2.234 60', 1000' 12.271, 1/4 14.665 @ 93.94
RSX said he had just an intake for mods.
At the time I had a Gen4 header, Greddy SP 1-7/8" ID cat-back, S4 cams, JWT ECU (no cam program), 2 pc. ur pullies, new clutch, 8.7 lb. flywheel, jgy lsd(phantom grip type), ~170 lbs. weight reduction, kuhmo 711 195/50/15.
AFTER that I put on a gen6 3" header and full 3" exhaust and dyno'd 163whp, so not sure what whp it was for that run.
BORNGEARHEAD ran something like 13.9 in his NX with similar VE mods, about 191whp IIRC - but that's about 400 lbs. lighter than your G20, weight worth about 1/2 second I'd guess, and he has quite a bit of track drag racing experience.
If you're putting down 190whp, with drag radials I bet you'd win. Very good launch on street tires should be closer - my guess anyway.
