[Lude-icious!]

ok, here's the deal, I have a 1989 hatchback si, d16a6....now the guy I got if off of talked alot of shit, and I didn't really care cause I knew I was gettin a good deal on the car regardless...so, he was sayin that he had a zc head put on it, and I just smiled and nodded right, and now my question is this, how do I tell what head I DO have...is there anything to identify it asides pullin it off??
any feedback is great feedback...negative or not!

the term zc gets thrown around a bit. there is the obvious twin cam zc(that i doubt you have) and a few singlecam variants. Why dont you look for a casting mark or number on the head. then we should be able to help. or take a photo

Bingo. Casting mark on the head is an ID code/number. There's the SOHC Vtec ZC, aka USDM D16Z6 or the non-Vtec ZC (JDM), aka (USDM)D16A6 (there's a slight difference though... can't quite recall it).

I believe I saw a number once and it said p28...or something 28, my car is in for suspension work, or else I'd go out and look...I'llhave it back tomorrow and have a good look see and get back to ya...the block is Deffinately the a6...its everything else I'm concerned about!
thanks for the help boys!

P28 is refering to the ECU i'm pretty sure

[Drag4life723]

well the thing is yes p28 is a ecu code but also part of some casting numbers on 92-95 vtec cars

i know that casting numbers are every where on honda and here it gose.

pm5-??? pm6-??? are what u will see on 99% of parts that have casting number on them in a 88-91 car so there is ur best bet if u get a castiong nuber for a head i have a program i type it into and it will tell me what car it came from. good luck and get back to me.

ok, for my head - pm3-5 is the number, and my tranny is L3 1446780

[superdewey58]

i think that is the number for the sohc zc which is similar to an a6????

[Lude-icious!]

I have the a6 block, that I am sure of, its the other parts that buddy claimed to have put on that I am concerned about...and its WHICH 'zc' head I want to know I have...

ok, for my head - pm3-5 is the number, and my tranny is L3 1446780

PM3 head is basic non-vtec used in '88-'91 D15B2 and D16A6 atleast AFAIK, maybe in newer D15B7 too etc..
L3 is basic 5-speed manual tranny also used with those engines in '88-'91.

What engine code does it say in block? looking left from header, flat part around block/tranny surface.
AFAIK "ZC" has nothing different compared to A6. Not even cam.

I already know its a d16a6, and where the identification #s are...I'm not as slow as some may think lol! but when I bought the car, I was well aware of the swaps that alot of people do, and I was just tryin to find out whether or not I had a y7/8 head or not..the tranny, I was just curious, the car moves forward, and for now that is good enough for me...but thanks for the extra info!
