Searched and got some good info but, anyone here have actual dyno sheets for the difference between A6/ZC to DOHC-ZC?

Is the change even worth it in the long run? Opinions from people who have done this please?

Daily driver differences?

OH yeah, 91 crx si.

 

If the price is right, do it.

If it's too much, save the extra and go B16, you will notice a difference then.

 

in my opinoion i would just get a b18 LS motor because more parts are easier to come by.

 

you guys are missing the point.

the dohc zc will still BOLT RIGHT UP TO EVERYTHING I ALREADY HAVE IN THE CAR

Im not down to do a complete swap. the car doesn't need it.

Only asking to see if there is a noticeable gain between the D's of sohc and dohc.

stock to stock.

I have my hatch and my sedan to play the way overplayed B swap game.

 

come on guy. nobody's really responding to your thread because the question is too obvious.

dohc zc = 130ps
sohc zc = 120ps

what do you think?

there are tons of threads about dohc zc. do a search under "dohc" and filter out the non zc threads. or better yet, start with looking at the faq at the top of th page.

 

I would stay SOHC, for the simple fact between SOHC ZC and DOHC ZC is only 10hp. Plus when it comes time to replace stuff the parts factor comes in. But hey if you get a good deal, why not...

come on guy. You're missing the point still. TONS of threads blah blah. Yeah I searched it. reread the question. Driveability differances. Do you have one?

yeah, its what I was thinking. But I got a dual ZC for 75 bux.
Ive taken it apart and reasembled and the innards are CLLEEEEAAAANN!
Good compresion all across, and no losses on the leakdown.

 

:unsubscribed:

 

I have gone through this swap before from sohc to dohc zc....and its noticable difference in powerband that and plus MY DOHC engine was in better condition. I felt it was worth it for my budget.

Cool, thank you.

wow........ no one else out of all the people who say they own a zc in their car has any advice on driveability differances?

wow.

 

boost ur current motor

a6 &gt; all LOL

 

People make the DOHC ZC out to be crap. I have one and its a good engine, and I dont have a hard time finding parts. Maintence items arnt hard to find, and upgrades arnt either. Just check http://www.thezcr.com , there is a ton of info.

yup, and exospeed makes cams etc....I know of plety of other sites dedicated to the zc.

but what hasnt been answered yet is how DOHC ZC actualy feels compared to sohc zc/a6

I have yet to drive a crx with the DOHC and feel the differances myself.

Stock vs. stock.

Is it so hard for someone to chime in to the actual question? Thanks for the input so far tho.

 

When I swapped out my a6 to the DOHC ZC, I noticed there was a significant (not massive) improvement in power on the high end and that it sounded a little beefier. I'd reccommend the DOHC if you can get it done cheaply and if you're using it for a DD and want a little more "zip". Otherwise just put the money into the SOHC and build for forced induction .

 

I've had D15, SOHC ZC and I own a DOHC ZC, I've upgraded from all those cause they aren't good enough for my preference.

SOHC ZC is cheap, reliable and the parts are interchangeable with D16A6, a common engine.

DOHC ZC are a one of a kind engine, good power, but snap a timing belt, bent 4 valves, crack a piston. Go ahead, tell me which parts do I use? Remember, it's not the same as a 88-89 D16A1.

I'd stick with the SOHC ZC and sell the good DOHC ZC and use the many to upgrade some parts on the SOHC, like a Y8 intake manifold!

 

I'm swapping Z2/a6 to D16a9 ( 1600 16v DOHC )


in a few days when I get me rims back i'll let ya know, What I heard was very promosing!

Cool,thanks.

 

I had an a6 but never a DOHC ZC and not that i don't like it but i think there are better alternatives for making power, as for a DD I think it is a great motor, if you got it for $75 and its a good motor i'd say rock it...

Just other options, i know you already have the motor but here's another idea:

Ever think about a mini-me though wouldn't you make the same amounf of power as a DOHC ZC, thow the DOHC pistons in it and slap on a z6 head, Depending on the piston to deck hight not sure but your have a dencent high compression motor some where from 10:1 to 12:1 probably pull pretty hard

 

If you plan on tuning go dohc, if u want a quick daily driver go sohc

That's the dumbest thing I've heard all day...infact I'm gonna sig that. You use the PM7 ECU MADE for the DOHC ZC. No need for tuning.

 

actually thats not too dumb. I think what he means is a dohc has more tuning possibiltiys and more hp in the long run. while the sohc is a drop and play motor.

 

by tuning i mean intake and exhaust duration adjustment as well as higher redline capabillities

 

by the way the ecu is not the only thing that needs tuning

Higher redline capabilities? Maybe if you upgrade your valvetrain yes. Stock no! You don't put a B16B ecu and cams with a B16A valvetrain. Why? Cause the springs aren't meant for the aggresiveness and the higher rpm of the ecu. The engine would die. Just like the ZC would.

And concidering he asked for STOCK gain, tuning is not one of his wants.

SOHC ZC have WAY more potential then the DOHC ZC. With the SOHC, adleast your options are open to other D series parts (such as VTEC head, Y8 intake manifold, even other aftermarket stuff like S2 stuff). The DOHC ZC, is a dead end engine.

You can't tune an engine (non-ecu parts) unless you upgrade the parts over stock. If you do that, it's expensive, he might aswell upgrade to a B series and go from there. He will notice more gains tuning a B series over a D series anyday.
