Let me know if I missed anything


Thanks for the confirmations from those who are contributing.

Dont forget to check out the Archives: Sean has Mucho information there including Head specs on valves:
http://d-series.org/viewtopic.php?t=45

[jam4484]

You are right...the a6 head is a pm3. I just checked for you and mine says pm3-12. as for the others I have no idea.

[BseriesKllR]

My D16z6 head says P08-4

[sqmark]

My D16z6 head says P08-4

Mine is P08-6

It generally work with which ECU runs the engine except the Z6 which has a P28 ECU but the JDM D15B runs a P08.

[RedCRX90]

SOHC ZC head ID is :pm3-9

[DOG]

88-89 (JDM)ZC D16A1 ?

[RedCRX90]

D16A6-- oh and hondadog i stand corrected, the bolt pattern is the same on the ZC intake side, except for it only has 5 studs. the USDM manifold has 7... im goin to check shortly to see if the other two holes are drilled...

[DOG]

Thanks Red.

[RedCRX90]

yea dude the holes are drilled and tapped for the other two studs just gotta put em in...

[Calesta]

SOHC ZC head ID is :pm3-9

My SOHC ZC says PM3-5, so add that to the list too.

[DOG]

Keep them coming. Still need confirmation on :
D16y8
D16y5

I will also add #'s for the D13 and D14 series if someone has them.
I will update the list tonight. Anyone with JDM(ZC) please note what engine you have along with head casting #.
Thanks
Dog

[Calesta]

Crap... I took a DOHC ZC apart a few months ago but didn't get very good pics of the head casting. Maybe you can extract something from these pictures:

[RedCRX90]

My SOHC ZC says PM3-5, so add that to the list too.

Hmm well since mine is a PM3-9 makes me wonder if theres a compression difference... maybe one of us will benefit from this difference/discrepency.... :wink:

[RedCRX90]

soo i just talked to another buddy of mine who just swapped in a JDM soch ZC into a civic hatch. yea well his head number is pm3-16... this keeps getting loonier. im starting to wonder...

[f00ker]

who speaks japanese and can call honda of japan?? lol

[FMYStreetRacer]

vx head is p07-1 if the -1 makes a difference.

[f00ker]

soo i just talked to another buddy of mine who just swapped in a JDM soch ZC into a civic hatch. yea well his head number is pm3-16... this keeps getting loonier. im starting to wonder...

Maybe the suffix doesn't matter... maybe it's just a batch number or something.

could be. Or the machine number of which one cast it.

(same thing really)

[Calesta]

Yeah- same thing... just markings to identify something in the manufacturing process, not necessarily a different design. I'm betting that all the PM3 heads are the same.

Natural gas, started in 96-00 generation of Civics, used a high compression 12.5:1 setup. It was mostly a fleet sales only car.

[DOG]

Possible to convert one to pump gas from natural gas? I found one for $175.00 and it has 60,000 miles on it.

[Calesta]

You mean convert it to run on gasoline instead of natural gas, right? I'm not sure.

[DOG]

yeah thats exactly what Im thinking.

[SilentWrath*]

i just checkd my 90 civic dx and it had a pm9-5...so i guess that means someone put a d15b7 head on it before i got it. its still dpfi so i always figured it would be pm3, then i go to look at it cause i had my hood open and i was shocked to find a pm9-5.

[DOG]

Better head than the b2 IMO, though its probably not much different. Kinda cool that you foun out though. Thats pretty much why I wanted to post these numbers, so people know what they have and what they are buying. You should also be able to find the date stamp on there. Stamped on a circle right next to the casting #'s.

hopefully ill get more out of it when i convert to mpfi, and get a y8 IM on there....since the b7 head was designed for mpfi and the b2 was designed for dpfi...theres gotta be some difference in the cams or something right

[green_hornet_96]

1996 Honda D16Y8 (stamped into block)
Cyl head: P2J-8 (i think, thats whats cast into the front of it)

There's also a sticker on the top of the tranny, it says K4F, I think thats the ID. I couldn't exactly get my head in very far, so thats the best I got.

[DOG]

Thanks. Ive been looking for that one. Ill use the tranny I.D. too. 8)

88-89 (JDM)ZC D16A1 ?

i think that the 86-87 (if there one) is HM-3 and the 88-89 is HM-4. my friend has 2 motors sitting in his shop and that's the numbers. the distributors can't be changed, so they are differnt heads.

What else you want to know? Its what I converted from.

The actual casting numbers on the head should be inbetween the exhaust ports or close to the dizzy.

[Rexinre]

P2J-1 is inbetween the exhaust ports. On the block there is a number as well right under the stamping that says D16Y5. What is a Dizzy?

updated with new info

[SilentWrath*]

hondadog,

me and someone else on here have ef's manufactured in canada, and what we have noticed on both of our cars is that even though we have dpfi dx's, we have a pm9 head???

when it was just me with the pm9 head i thought someone just swapped it over cause they had one lying around, but after hearing from this guy, whos car was also made in canada, it makes me think that canadian ef's with dpfi came with a pm9 head from the factory

my question is this, what cam does it have?? a pm3 out of a d15b2 designed for dpfi?? or a pm9 out of a d15b7 designed for mpfi???

thanks
andy

interesting. I have a b2 in y car and tonight I will take a look my 91DX was made in Canada. I will compare it to my b7 head in my garage. Ill let you know tonight.

[DOG]

Well guess what? PM9-6 and next to that is the ate stamp 91. Makes me wonder if I made a mistake or if there was a difference in the US vs CAN Honda's. My guess is that the canadians were using the new b7 head when our market was using the old b2 head in 91. Of course I could be wrong and there actually be no difference either. We need to get some more people with USA b2 88-91 heads to confirm this. And also 88-90 Canadian b2's. What does the date stamp read on yours. Its right next to the casting #. Maybe the only thing they changed on the head is the cam specs when the b7 came out.

ok....you have some wrong info on there

the d16a1 isnt a jdm car..... its a the usdm integra 86-89

not sure of the casting id but on the d16z1 head (which is fitted to a hrv which is a small 4wd type vehicle over here in the uk) the head has the same camshaft as the d16y7

[billytyper]

are different generations of EX models both having vtec head interchangable?
like a 95 EX with PO8 and a 98 EX with P2J. I know they are different by OBD1 and OBD2 but that may only be the sensors. I found some links to comparasons but they were dead links.

[DOG]

Yes you can interchange them.
