I recently picked up a 03 that needed a 3rd gear. After getting in to it she needed a bit more. So I went with a JE 558 kit pro circuit T4 exsaust and header k@n filter kit dyno jet kit with 175 jet and cut 4 coils off the spring and a Tokyo mods cdi. All that def made some improvements but mehh. When I build something I build it all out and scary stupid fast. So my next mods are guns be web racing cams and ship my head and crank to C an S racing to have port polish 5 angle valve job with the +1 valves and ship my crank to have the hot knife light weight stroker kit built and light weight flywheel. Also going to get a bad ass racing clutch and baskit, just haven’t decided who yet. So question is…. Is there anything I’m missing or could do different to get more power. I want this thing stupid fast and scary. I just got another 03 chasie with no motor I’m going to stick a gsxr 750 motor in it with existed arm to run at the track. Might add a turbo if I can’t break 9 sec. But I want to build a scary ass pres with the stock motor.
