I have a d16zc block with d15b2 non vtec. I have yet to convert to mpfi, but i found a d16y8 head from 96 civic with intake, tb, injectors, fuel rail everything. I was wondering if the intake on that head is an mpfi. The guy wanted $100 for all, is it a good deal. Would it mate to my head also? I know i will need the jumper for ecu, but what ecu would should i use? Thanks for all of the help.

 

Your post seems to be missing ALOT of info so I'll answer this as best as I can.

The question in your title is incomplete, D16Y8 "what?"

The intake manifold originally intended for the D16Y8 head is not DPFI. It will mate to your [D15B2] head. The ECU you use will be dictated by which OBD configuration you want to run and which head you will be using.

Trying to figure out where the D16 ZC in the title comes into play.


Is it worth it?
Depends on what you consider worth it.
Figure $300 if you score awesome prices for the head, intake manifold, jumper harness, and then the ECU.
Not sure if anyone runs the OBD2 - usually done with OBD1 and a P28 ECU (optionally chipped for better D16Y8 mapping).
Head gasket. You'll need to replace it.
Water pump, idler pulley, and timing belt stuff while you are in there.

You'll be a little more quick, but it won't be like a turbo.

 

Ok what i was trying to say is that someone told me they would sell me a d16y8 head that will come with everything for 100. I am planning on going turbo after i get all of the other things out of the way. But as of now i have a d16zc block and a d15b head. Its has the dpfi and i was told to swap to mpfi. Would that intake mani work from the y8. If i do buy the y8 head i want to swap the intake mani to my car and go obd1 from my understanding. That way i can go through the y8 head and get it ready for boosting. Or would it be easier to just build the head and then swap it.

 

do you understand "D16ZC" is a completely redundant, and non descriptive abbreviation?

WHICH D series block do you have? DOHC, or SOHC ZC? Was it VTEC, Carb, MPFI? ALL of those are D16ZC essentially.

learn what ZC means please.

 

The Y8 intake manifold would work for converting to MPFI. OBD1 is ideal for ECU purposes and seems to be most common. When you install the Y8 head is up to you but the upside right now is that if you only do the MPFI conversion you limit the possibility for error/mistakes to just the conversion itself and not a head swap. It's up to you though.

Also, there's no such thing as a D16ZC so in the future you should clarify exactly what you have. Same with the D15B head, there is more than one version.

 

The head is non vtec sohc, has dpfi. The place where the vtec solenoid is supposed to go is capped and sealed. Not sure which d15. Was told a b2 but who knows. The block is also stamped zc. I just want to know if i buy the y8 head build it up, then boost or boost with the head i have on it now after doin the dpfi to mpfi swap.

 

that cap is not for vtec solenoid ive heard its something to do with fuel for the jdm motors but no sure on that. you even say the heads non vtec but somehow its for a vtec solenoid? it all depends on the amount of work you wanna do or are capable of doing both jobs you wanna do require new parts and running wires and making a new harness.

EDIT: so the jdm non vtec head has the spark plugs closer to the intake side not the exhaust side and none of these motors that are designed like this are vtec also to the jdm sohc zc has a weird cam lobe on the outside of the main caps that really does nothing but i.d. it as a zc cam. trying to help you i.d. your head your confusing us

 

It's originally a carb version. That opening that is blocked off is specific for the carb (mechanical fuel pump related if I'm not mistaken). And ZC heads come in both versions of spark plugs being on either side of the head and still be non VTEC. That's really just a difference of old vs new. Don't worry about the details though, I'm sure it'll confuse you even more. You just need to know what yours is and that is now clarified (for the most part anyway).

Choice is up to you for which head to use. Both have advantages/disadvantages.

 

Yea im very sorry for all of the confusion to everyone. The title does not help much lol. I am doing all of this off of my phone and it get aggrevating. Well when i got the car its was leaking oil from the spot the vtec solenoid goes (on vtec motors). I know its not for that but its easier to say that because its in the same spot. Yes the plugs are by the intake manifold. I wish i could post a picture but im on my phone. So what i want to do is boost eventually. I am buying a d16y8 head with tb, intake mani, everything for 100. He said he also has a p2p ecu for 30. Would that ecu work or should i just go with the p28 ecu. Would the y8 head mate properly to the d16zc block. Would it be better to boost the d16y8 head or the head i have now? I just want to do the car right and get the best out of a SOHC. Again sorry for all of the confusion to everyone that is helping me out. Hope i cleared some stuff up.

 

The block thats is in my car is stamped zc. The head that is on it is a non vtec d15b2 sohc. Just googled it.

 

what youre not understanding is that both the DOHC and all the variants of a SOHC ZC are ALL STAMPED "ZC".

but clearly your ZC block is not a DOHC block.

and that area "where the vtec solenoid is supposed to go" on the head is not where the VTEC solenoid was, its where the mechanical fuel pump linkage went thru, because that block used to be a carbureted engine. its very common to see.

anyway, at this point, yes, you should be able to slap a y8 head on there if you desire.

 

Yes tyson i do understand. Can you use a dohc zc block with a sohc head?

 

Yes but it's not a bolt on and go affair. The most common answer is no it's not possible to mix/match ZC SOHC and DOHC heads/blocks..

 

dohc and sohc ZC blocks are not the same.

thats what you dont understand. or else you would have never asked this question.

 

Which proves my point. If i said it was a d16zc block why did you ask if it was dohc or sohc? I do understand the difference between the 2. Its not a b series motor. That was a rhetorical question by the way.

 

not all SOHC ZC bottom ends are the same either.

you still dont seem to get it.

 

Buy the y8 head, and just swap the intake manifold, and do the dpfi to mpfi swap for now and convert to obd1. Leave the head and block alone until you are ready to boost it. It seems like the last person who had that engine must have screwed up the original head if they put a usdm head on a jdm block

Also I would suggest getting a shorter geared transmission if you don't already have one

 

^We never had the carb'd version here, so it's more than likely not a USDM head and in fact the matching head for that block.

 

Then i take back my statement that it might have had a head swap done

 

sounds like a full sohc zc obd0. these motors are pretty much the same as sohc d series meaning heads exhaust manifolds and intakes are swappable doesnt mean the computer s are the same. just a simple mpfi wouldnt require a jumper harness while converting to obd1 or obd2 would require a jumper harness. im sure alot of this info can be found in the faq search mini me.

 

To make this easy -
YES
the Y8 head will work on your engine block.

Does the package the guy is selling you include the Y8 distributor?
The Y8 distributor will work with OBD2 or OBD1, however the D15b2 distributor you have on now will NOT work with any MPFI ECU.


The P2P ECU is the OBD2 ECU for the Y8 engine. With the correct conversion harness, You could potentially use this ECU and it would run the Y8 head just like it was meant to be, however the other modifications to the rest of the car (second cat with O2 sensor, modified fuel tank for pressure sensor, etc) make the OBD2 ECU undesirable. Additionally, tuning OBD2 is more complicated than OBD1.
I suggest you go with the OBD1 P28 or another vtec compatible OBD1 chipped with the P28 map or a Y8 ready map. In the long run, this will be a great option for your future turbo tuning needs.

 

Yea im not to sure if it was actually swapped, its just what the guy had told me. Yes the distributor will come with as well. Ya i have heard from many people on how hard it is to tune obd2. Im just going to go with the p28 i feel it to be better in my situation. But any way thanks you guys have nailed it. Thanks for all off the knowledge and answer much appreciated.
