Is your RSX modified? Is it similar to the 2.0 Si?

Weight, gearing, throttle response, etc. play roles. But to compare the 2.0 liter from the Si and the 2.0 liter from the FR-S, as far as torque, here are a few sample RPMs:
3000: Si = 127, FR-S = 141 (11.0% advantage)
3800: Si = 121, FR-S = 122 (just about the same here -- FR-S's torque trough, Si still doesn't exceed FR-S)
4800: Si = 116, FR-S = 142 (22.4% advantage)
6200: Si = 134, FR-S = 140 (4.5% advantage -- Si's torque peak, Si still doesn't exceed FR-S)
Si does maintain torque for further up the rev range. It catches up around 7100 and hangs on longer, thus it has a higher top end rear-wheel horsepower number (180 for Si, 174 for FR-S, source for both is Automobile magazine).
