i have a 91 ls engine with a 92 gs-r tranny swappen into my crx with a 50 shot but im just not happy with my power band my top end just dies off in each gear any suggestions will help thanx..  

the ls engine to me is a low rpm torque motor not a high rpm motor, that's basically why its not really fast at high rpms and that's why honda decided to put vtec on their high performance engines you can try a bigger exhaust and header, an intake, but what i think would really help are cams just remember that your idle and low rpm power will suffer.  

thanx civicking i already have a new port and polished head and matching intake and throttle body on the way so ill get the larger cams and open the exhaust up thanx again
