are there any stampings or anything of that sort on the head distinguishing it from a d16a1 head?

 

BUMP

 

well wont the head be stamped with the code...
ZC = pm7?
d16a1 = pg7

that should be right on the side of the head to the left of the exhaust ports.

 

The intake manifold bolt patters are different.

 

i have so many ?'s between these two motors, the d16a1 i heard puts out 130 bhp and i heard the same about the zc (130 bhp), but i hear the zc has a lot bigger cams, now can you bolt on a zc head to a a1 block? and can someone explane the hp tq differences

thanks

 

also there is the h stamp the stamp on the zc is on the ex side and the teg is on the intake side that is one the teg is like 118hp and 109 tq that is just a little more than a stock si motor d16a6 and also the teg dont swap straight in the back motor mount is different...

so what will i need to complete the swap? just a rear mount from a 88-89 teg

 

you are putting this into 88-91 civic or crx?? umm i thought you couldn't put in the d16a1 without custom fabrication of mounts...or else wouldn't everyone be doing it?

that was my understanding when i first bought my civc and was consiering the zc swap. could be mistaken though.

 

i have a friend with a d16a1 in his 87 civic and his room mate has one in his 89-90 crx, they said it wasnt that hard, so i don't know how hard it is, actually i worked with him at a different store for a few days, but i don't know to much bout his car.

any knowledge on this swap would be sweat, the reason im really asking for his benifit, cuz he says he can pick up a zc head and i said do you know the stampings or identifing marks that makes a zc instead of a d16a1 teg head, and he's like well i didn't know honda did that, so i was finding out so he didn't get ripped off and it's good knowledge for me, id like a teggy motor, i havn't really decided, so maybe some more info in this thread will help me decide

peace

bump for more info
