swappin ZC in the rex si. What HP are they, but better yet, where is the power most noticeable? i like tq myself, but also top end pull. yes, i understand its not a drag motor, but compared to my d16a6. thanks guys!

 

after reading my own post, i realized i sound like someone who didnt search or anything. it will be stock for a while besides a sr or ca intake. with a pm6 ecu. sorry if i sound like a dumbass, just wondering and tryin to learn.

 

sohc or dohc?

 

if your gonna stay stock and want a cheap motor. A zc vtec is what you need.

hauls ***; torque kicks in at low rpms; vtec kicks in at top and your off. Best price for the best d series performance engine.

 

The dohc kicks in right about 4k. The sohc doesnt really kick at all, heh. It still pulls but I the dohc is noticably quicker up top.

 

the sohc non-vtec is really just a low miles d16a6 with a 4-2-1 exhaust, slightly ported intake manifold, and a slightly more top end cam. some of them have the better 92+ all metal and higher compression headgaskets.

the dohc is more.

the sohc vtec is to the d16z6 as the non-vtec is to the d16a6.

good luck.

 

DOHC is what i am getting. thanks guys. make me feel even better about my plans. I just got back from NOPI about an hour ago, and a guy there had a turbo ZC and ran 10.96 i was impressed!!!

 

were's sired91 when you need him, the differnece is in the exhaust lobes and the header, nothing else, nothing with the intake mani

 

Some other advice, to answer your previous questions, they are rated at 130HP for the DOHC, (not sure about whp tho), and you should swap out your ECU for a PM7, or just get a PM7 program chipped into the PM6.
