SOHC ZC vs DOHC ZC

[branman_crx_guy]

Aight, i know the basic difference, ones dual over-head cam ones not. But i was just wondering wat car the SOHC ZC is from and wat the ratings are for hp and torque and compression, cuz i was on hmotorsonline ( this page ) and it had those ratings. Just wondering if they're are correct..also, is this engine hella easy to put in and does neone have a picture of it? Basically nething u can tell me would really help me out cuz im orderin today. Thanx.


PS Im not doing DOHC ZC, for complicated reasons, thats y i need to know about the SOHC.

dont get a sohc zc ... it will not offer significant gains over your current si motor. Get a d16z6 out of a 92-95 civic ex

also there are no hard numbers on this motor. some people say they are 108 hp ... while i have heard others say they are 118hp.

but yes, it is the same as any other d series swap ... whoever had my car before me did the swap themselves .... and didnt put the mpfi in along with it

Why can't you do a DOHC ZC?

SOHC ZC isn't even going to be worth your time and money. Might as well just leave the motor stock.

Just get a z6 or a y8 (sohc vtec)...they produce almost as much hp as the dohc zc and parts are alot easier to find...prolly have less miles too...

i agree with the wise man.

The pic on the right in my sig is a SOHC ZC. Mine was worth the $225 i paid for it I bought the car with a blown engine so i didnt feel a difference. Well . . .

Edit: The swap took my partner & I about 3hrs - engine/tranny - running & driveable.

here goes another pic(better) taken shortly after swap.

Ok, well heres my situation, see if you can help me out. The guy doing my swap is a deuche....that is, he says he can't swap in any engine other than what comes in the car or else its illegal . I hate ppl like him, but he does swaps all the time so he does know what he's doing, just doesnt know wat he's talking about. So I'm worried if i buy the DOHC ZC and he looks at it, he wont do the swap cuz its not the same engine, then i'm f*cked.

Also, I plan on selling my engine once i get the swap and get a new front bumper, so i dont want to spend a lot of money on an engine when i wont be gettin much of it back.

So now I want some advice, wat would you all do in my situation? I dont really know nething about D-series engines cuz i always wanted B-series, so I dont know prices/ratings, so if neone knows of a better engine thats the same price plz let me know asap. Thanx

PS I am planning on buying an engine today, so plz hurry thanx.

PPS Also, I really need a new engine in the next few weeks, cuz im driving my car to Atlanta for Nopi, and this guy can put it in in two weeks, so im kinda depending on him.

Just get a z6 or a y8 (sohc vtec)...they produce almost as much hp as the dohc zc and parts are alot easier to find...prolly have less miles too...

Do they get swapped in as easily as the other D-series engines? Cuz i see its from a different generation, so i wasnt sure if u'd have to change wiring or nething like that, cuz he wont do that stuff either. If it is easy, where can i find them for cheap?

[91civichatch2571]

Is he doing it for free? If not then find somebody else. Also, 2 weeks is a damn long time. I did mine myself in my garage and it took 2 days. Definitly atleast go sohc vtec or doch zc, dont do a pointless swap.

Get someone else to put the DOHC ZC in for you.

[branman_crx_guy]

No it wont take him 2 weeks, he can just take my car in in 2 weeks, he said he can do the swap in 2 days as well. And i dont know of ne places who will swap in an engine, and he said he'd do it for $440, thats including a clutch too. Honestly, i have no idea if this is even a good price for the swap or not, but i dont really have time to do it or know of neone else around in maryland that'll do it. If anybody out there knows of someone that you think is cheaper and would be able to do the swap soon and do it competently, let me know.

PS Sorry for the lame newbie type questions, but like i said i know nothing about d-series and have a short time frame to work with.

Haters...

The difference between the SOHC ZC and DOHC ZC is what, 10 HP. You can easily make that up with intake & exhaust alone.

One thing that no-one ever mentions about SOHC engines is "reciprocal mass".

The reason why Honda continues to bring out SOHC motors, as opposed to DOHC, even in the years 1988 - 1991, (competing with others like Toyota and Mazda who both brought out DOHC motors in entry level cars, yet Honda SOHC D15 motors still produced the same power as, say, the DOHC Toyota 4AF) is because a single cam uses less engine power to drive the cam. Two cams soaks up TWICE the engine power that one cam would. From the same bore and stroke...

If you raised the compression of a SOHC ZC to the same as a DOHC, chances are you would get the same output...

On the other hand, two cams allow for better control of timing, as well as valve angles, better flow.

look i can be a hater because i have this particular engine in my car. I finally got to drive a 88 civic sedan the other day with the dx motor and even though im running dpfi my motor is a nice difference.

But over an d16a6 its basically the SAME motor, other than the fact that the sohc zc is said to have a more agressive cam, and about 10 more hp. It would be a much better choice in this particular instance to get a d16z6 in my opinion.

The d16z6 is a SOHC motor. So it isnt like we are all completly hating on the sohc.
