Hiya everyone. I was wondering about putting a 330 kit on my 02 300ex. What is all involved with this? The kit comes with a Namura 330cc big bore piston kit (piston,pin,and circlips) & Steel bore cylinder kit & Namura 330cc top end gasket kit. What all else would i need? I know i would have to jet my carb out, but what jet should i use? Would this also make my compression high enough to have to use 93 octane? I appreciate the help guys.
