i just picked up another EF hatch and i want to toy around with it . i have a whole SOHC zc motor out in my shed that i am think about throwing in this new hatch but i want to know if i would be better off putting a vtec head on it or should i stick with the zc head. I have done some research on the sohc zc and i found that it is 125hp in stock form with the carb's on it. i was wondering how much might i gain by going vtec on this and if i it is worth the trouble.
