I'm assuming by GSR, you're talking about the older Integra GS-R. If that is the case, here are some stats for you:

GS-R(2dr) - 170hp, 128 ft-lbs., max torque @6200 rpm, max HP @7600 rpm, weight - 2572 lbs.

Base RSX - 160hp, 141 ft-lbs, max torque @6500 rpm, max HP @6500 rpm, weight - 2694 lbs.

The RSX has a little more torque and HP maxes out lower which will get you going quicker, but it does have 10 less HP and weigh a little more.

I would probably get the GSR, since it will be cheaper, and with the savings, make mods to get it to perform better - carbon fiber hood, CAI, and possibly a turbo kit. It will probably end up costing you about the same price as an RSX base, but you'll definitely have a much faster car.

Hope this helps.
