I have a 97 f22b nonvtec 2.2l 4cyl and i want to put a vtec head on it but i cant find them anywhere. i am told this can work, i was wondering if there were any probs i dont know of though, what negative affect can this have on my car? does anything need to happen with the ECU? also, i've been looking everywhere and cant actually find the part, should i just hit up my local junkyard to look for it? thanks.
