service done before anything. you will probably notice small power gains with exhaust and intake, but probably the biggest noticable gain will be from u/d pulley, atleast this is my own personal experience. if clutch feels rough, get a racing clutch ive heard, but u know im not sure about that since i have an automatic. :-) oh yea, make sure to set aside a bank account for a big hair dryer (electric supercharger/turbo kit) and put your wheel on backwards.
