both of these engines have pretty much the same stock power, one with vtec the other dohc. which would be easier to build for more power, and which would be a better swap for a 91 civic hatch dx? the zc parts are harder to find ive noticed. just wondering which could be built better and which accels better.

 

i take it you mean a d16z6 or y8... and it'll be easier to find parts for the SOHC...

 

no, i meant jdm d15b, or dohc zc..

 

dohc zc has more torque, and they love forced induction, just get a dohc zc

 

i like the DOHC

 

dohc but there both fun little motors

 

If the DOHC ZC is in better shape go for it over the sohc engines. It's just a more responsive motor overall. If you can't find one in good enough shape, get the sohc engine, but try to get a DOHC ZC. I'd get a d15b vtec over a sohc zc.

 

what tranny would you use with dohc?

 

civic si tranny or a 89 teg trans... i use the teg one.. but i have an si too , but i dont know whcih one is better to use. alot of peple run the si .. id like to know myself.

U sure u can use the pre 90 teg trannys in an EF?

 

u cant use the integra tranny on a d series motor. the mount is differnt.

 

I vote DOHC ZC with Si trans as the best combo (of the above choices).

With a Greddy kit and crappy fuel management, I was able to make decent power and somehow not blow the motor up even with extremely crappy a/f ratios.

 

This has the thread I was looking for for awhile. I myself am in the middle of this very debate.

 

HP/TQ vs Dollar amount the DOHCZC wins in both. Availibility is what most ppls problem is, but here in Cali DOHCZCs are abundant. Plus, I've driven a car with the d15b/vtec and my DOHCZC and my DOHCZC runs game on d15b/vtecs with the same mods. But then again, my motors pretty stout, 195 across all cylinders. The thing is, you'll be able to get valve-train/head parts much easier than with a DOHCZC. I guess its all in preference, if your in Cali and you drive to my house, ill take you for a ride in my rex, then maybe you can find some1 with a d15b/vtec and see the difference for yourself. Just my opinion. - Darrell

when you say si tranny, do you mean the one from b16 or d16a6?

 

from the d16 cause the dohc zc is a d-series

 

Depends on what part of CALI you're looking at
In southern CALI there are different classes of people like everywhere else
Like in the Irvine/South OC B series/Custom Turbo set ups are whored out cux they got the $$$$$$$$
in the 909(18" lifted trucks minimum) where people are more budget minded homemade Turbo setups RULE
but I hafta say the DOHC ZC is pretty common over here despite not being smog legal
I've even seen them at local junkyards in "EF" cars.

 

i say go zc it even looks cooler

 

If you go with ZC wich is a pretty nice motor (i run one myself), you might have to do a little modification with your hood or just get a zc hood. It's a tight fit with the cam gears so...thats my 2 cents.
