I currently have a 2000 model Excel twin cam. I am just about to start modifying the engine and want at least 100kw or so without forced induction. I was thinking of a twin throttlebody kit, chip, ported and polished head, shave the head to up the compression, bigger injectors and regulator to match. Can anyone tell me of how much this will approximately make as no one here has done all this and can give you a straight answer. If this wont make the cut what else can I do to it without putting quad throttle bodies on as I don't want to have to change the computer and the budget won't extend that far. Nos is also out of the question.
