i have a couple questions here!! as far as performance goes wich one is best?? as far as $$ goes i know that it is a lot cheaper to swap in that dohc zc just becuase i have a d series engine already!! also i was wonderin if u can v-tec a dohc zc. if so i would probably get the dohc zc because it is a direct bolt on!! i just love the sound of that v-tec workin.. it is the best sound in the world hahahaha!!!thanks felas

 

anyone willing to help?? i would really appreciate it!!

 

can't do vtec on that dohc zc, but it's pretty good without it... especially if you are gonna boost it too.
