i've heard of more problems in the rsx specifically through consumer reports and stuff, something they're supposed to fix in '03 i believe, although i've never driven one myself so i can't say from personal experience (i own an integra myself).
as the rpms become too high, the valvesprings can't keep up and then the valves don't open/close quick enough. this is where the s*** hits the fan so to speak, as the piston hits an open valve, it's either bent or busts a hole. if you're lucky it's just bent.
