SOHC ZC VTEC 1.5 OR 1.6 ?
 

Hey yall, wats sup..new to site and forum. Mad props to this site by the way. Ok..here's my problem..I blew up my d16z6 with nitrous and at the time I had just finish my turbo setup- t3/t4, which I had to sell cause I was broke from building it and needed money to replace my engine..so..had to sell my 2 year project ----! any ways I could'nt afford a b series engine, so I bought what I thought at the time was an exact replacement but jdm version of the d16z6, but I guess its not. The block say's "zc" and thats it nothing else and I've been trying to do some search on this engine..so far no info I can use. Some web site I went to said that the zc makes 130 hp but does not mention if its sohc. Any info would be helpful, peace out fellaz.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

yours is a single cam? its a 1.6 motor like the Si/D16A6 motor with a little higher compression with like ~110-118hp. the 130hp is the DOHC motor...

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

hmm....so your saying that this engine is producing less hp then a d16z6, strange.. cause this engine is a vtec it should atleast make more hp than an si 1.6 none vtec. It pulls pretty good feels better than my d16z6 but some places says there's two version of the vtec sohc zc a 1.5 and 1.6, I just wanna make sure that this egine is a 1.6 before I turbo charge it, dont wanna waste time on a 1.5. maybe I'm wrong. Keep the info comming. peace out.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

sorry i missed that part...you put a VTEC head on it??? im pretty sure that they didnt make any VTEC ZC's...

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

if the block says ZC, its a 1.6l

ZC's are considered Non-vtec engines,

1.6l SOHC ZC's can get the Vtec head swapped on them, (it is called a Mini-me) and will put more output than a d16z6

1.6l SOHC ZC's put roughly 118hp to the flywheel, with the correct ECU.

but sometimes people get mixed up calling the ZC-G the B16a, which is dohc vtec.

There is a sohc vtec zc. I got one years ago directly off a container from an importer down here in so cal. From what i understand they are rated at 135 hp. The vti sohc vtec motor the 1.5 liter there makes 130 and also comes with a lsd if you decide to get the tranny with it. Sweet stuff for all the d series junkies out there. Just picked one of those up this weekend at soken in L.a. They exist. Also most Jdm motors extra power comes from higer comp.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

---- all 3 motors.
do a b18a swap in that bitch. torque, t25 and boost = oh so nice torque curve!!

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

I would like to see some proof.. not saying its not true, but I have never seen one in my life, nor have I ever seen one on any EDM or JDM motor sheets.

proof of the 1.5 vtec motor.


here is proof for the sohc vtec zc http://pgmfi.crx-forum.org/resources...ification.html

Look under p70 ecu. Sorry no pics but they exist.
I have installed a few in my day and they say zc on the block. Do a search on yahoo with sohc vtec zc you will come up with some more sites. Also the p70 ecu is internally identical to a p28 ecu and can be chipped just chipped a jdm sohc vtec zc ecu today.

Proof!!!

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

interesting... I knew their was d15 vtec's, and d14's I drove a few while I was on my trip to Ireland. So it looks like the OBD1 SOHC ZC did come in vtec then eh.. wow, guess you learn something everyday ;)

I still would like to see one..

Jeff

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

I'll try to take some pics of the swap i did for a guy about a month ago. Installed the sohc zc vtec motor and the vti lsd tranny.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

thats great info chris, so these are all obvisouly going to be OBD1 engines, and they came from what model?

I'm guessing the pistons are not domed in this version of the ZC.. any ideas?

when you refer to the LSD tranny the vti, that is also for 5g civics correct? using hydro? Do you know the gear ratios?

Has all the models that came with the zc vtec motor. I have yet to pull a head off one of them but it may. So many jdm motors have slightly higher comp. so that's where the extra power comes from.Vti Lsd tranny has the same gearing has an ex/si tranny.yes it's for a 5th gen hydro. Alot of importers down here in so.cal are selling them for dirt cheap. got one for 200 bucks. trips people out. A d series LSD. Just wanted to also say great site. I'm finishing up a turbo kit now with alot of info and ideas coming from your projects. Thanks and keep up the good work.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

Thats a great link! now I know for sure my egine is a 1.6l cause the other zc 1.5L are label as d15b vtec mine just says "zc" and the link you gave has the proof I needed it clearly says "ZC VTEC 1590cc SOHC VTEC, 130ps" can't wait till my turbo kit is finish, like to see how this baby pulls. peace out

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

Yeah...I just drop this motor in 6 months ago and never got any real info on the block all I knew was that its say's "zc" on the block. evreyone here has answer some of my question but one still remaining is welther this is a 1.6 or 1.5 but some link I check from chris post http://www.vtec.net/articles/view-ar...rticle_id=7367
shows a ZC VTEC 1590cc SOHC VTEC, 130ps which is a 1.6l and
D15B 1493cc SOHC VTEC, 130ps which is a 1.5l same hp but more torqe on the 1590cc I'm assuming? can some one confirm this? peace out.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

Hey Chris do you have any info on where and how I can get one of those lsd "D" series tranny, thanks. I will try to get some pic's this week and post them up fo ya ta see. latez.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

im asking this for a friend....are d15 and d16 parts interchangeable?...such as intake, cams, valvetrain, rods, crank, pistons...any info is appreciated

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

Some parts are interchangeable. The heads on a d15/d16 are going to be similar, (if they are 16 valves)

Comparing
d15b2 & d16a6

Both use the same head, the d15 has a slightly weaker camshaft, but the entire valve train is the same.

bottom end parts are different. The DX has a shorter stroke than the a6. So crank and other parts are not swapable. The bore size of the pistons is the same. But if you buy a6 pistons for you dx, you are going to be getting a different compression. I dont know what the exact formula is.

I need to find the # of the imoporter. E-mail me at -------------------- for the contact info.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

Hey, I'm running the D15B VTEC in mine. It's running to full potential since right now I'm using a PM6 w/RPM activated switch with a DX tranny. Here's a pic:

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

hey thats pretty tight dawg...thanks to your pics i now definitly know that my block is a 1.6l. Your block say's "d15b" mine say's "zc" both sohc vtec tiiight!, I wonder how many other peeps has the same engine, I gues its one of kind, thanks fo da pics, peace out.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

I have had both in my civic. had the zc like 5 years ago. I have the d15b in my crx now. I think 130 rating for the zc is low. It ran faster then my dohc zc with the same parts and in the same car.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

Hey chris so..you had the zc sohc 1.6l vtec before or the dohc zc 1.6? hey did you find that info for the importer for the d series lsd tranny also is that tranny hydro or cable? peace out bro.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

aren't these D15b's in the VTi "3-stage VTEC" ?
I was looking thru some JDM honda brochures, and we noticed the "3-stage VTEC" motors in the 96-99 Civic VTi...

Kinda cool, imagine 3 stages!
I want one!

-Henry

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

Hmm with the 3 stage I think it's best to run it with the ecu it's supposed to go with since there are two solenoids on it.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

I have yet to see any 96-99 vti motors in the states. The only ones i have seen are obd-1 92-95. Also for everyone who wanted to know the vti lsd tranny is hydro. Sorry crx and 4th gen civic lovers.

Re:SOHC ZC VTEC 1.5 OR 1.6 ?
 

We also have the rare LSD ZC tranny for us 4g civic/crx guys.. ;)

Jeff

well, i was trying to find out some info on which i believe is the 1st gen sohc zc. ..so i did some furstrating looking around online and if the sohc zc is vtec, then the engagement should be at 5,500 RPM. I have one so ima try it out soon. ..Been having some ghost electronic problems. Probly the old ignition switch.
