its basically all about the driver... my freinds rsx type s wif greddy exhaust, and aem intake, and mines bone stock except for a jdm intake, type s cams and pistons, and i can basically keep up wif em side to side.... shifting about the same

preludes and rsx's were made about the same, weight difference is also bout da same, but i think da rsx is a few hundred pounds less...
