Hey guys. I have a really quick question that I am in dire need to know.

How the hell do you determine a ZC to a d16a6. Cuz I know from a far or close up to the naked eye, its hard to determine the two. Is there some kind of stamp on either one of them that would distinguish the difference between the two, or is there something else to determine them both?

Sorry to ask such a question, but I'm trying to currently buy a zc cam for my d16a6 since the only difference between my motor and a ZC Sohc is the camshaft (high lift on the exhaust <is that right?) But yea, please if possible provide factual and logical explanation as to determine a ZC cam to a d16a6.

Also, I have a guy who's selling one, and I want to grab it, but I wouldn't want to grab without really knowing if its a ZC cam for sure? So help if possible! Thanks.

 

There's a stamp near the left side of the manifold. It will say ZC. I know 'cuz I have one

he said cam not entire engine.

and i could'nt tell you the difference just by looking at the cams.

The stamp that you are talking about is located on the top left of the block itself... which wouldn't help me determine whether the cam itself... without the engine is a zc cam.

SIred91 - You couldn't tell me the difference? Shucks...Would this mean... If i wanted to buy it from the one guy that was selling it to me... I'd have to measure, with my micrometer tool, the difference? lol. That wouldn't be fun.

Please, any please... help if possible. I am in DIRE need of a way to determine it!

As far as I know... there is nothing on the cam that tells you which one it is. A few months ago I had to tape the end of the zc cam so I wouldnt forget which was which with I was messing with them.

 

I thought the zc cam was painted type-r red.

Man... hrm... the guy I'm buying the zc cam from says it comes from a zc block... but anyone can just proclaim they have one and sell me a freakin d16a6 one. =/ That's what I'm scared of.

The ZC cam that you had to tape, did it come from a zc engine (block stamp zc)? Did you do the same money saving mod? If so, did it help you're 0-60 to the point it was noticable?

Thanks for your input in my situation too.

Type-R Red? The cam comes painted? Or are you talking about the cam gear? Iono. I haven't heard of a ZC cam being painted red. If it is... well I'll be damned. Can anyone vouche on his proclaimation?

Hrm, any more solid and valid information guys I could use? If yes, please provide! Thanks so far everyone.

 

youd have to just measure it. the difference would not be identifiable by the eye, but it would show up in decent mic or caliper. if you knew the exact distance between high and low points of the exhaust lobe you could identify it outside of the head without having to use a dial indicator while mounted on the head. if you had a stock a6 cam, then you could compare measurements of course.

the only measurements ive seen and done are with a dial indicator mounted on the head.

what you can POSITIVELY identify is if it has a funny lobe at the end of the cam on the distributor end, then its the carburated SOHC ZC cam. you dont want that. the funny lobe is unmistakeable. it mechanically drives the fuel pump that carburated engines use.

that painted type r red guy is just trying to put his dork up your ***.
anyway, the difference I felt between the A6 and the ZC was minimal, the zc pulls a little harder and longer up top--6k to 7.2k-- thats about it. not much. but a usable gain if your into autocross like me.

so what autox class allows you to use another cam?

I'm pretty sure it would be allowed... since the cam is stock. So I don't see it to why they would prohibit that mod. Its like saying you can't have headers... =P

(BTW: I've never autox so I'm speaking from my ***. Lets see where it gets me =P)

Anyways... no one knows any way to distinguish the two cams from each other?

i just told you above how to distinguish it. you have to measure it. there are no other markings. the cam pulley is the same, so the stampings are identical.

they dont have to know.

no longer running that car though, since swapped to a zc block too.

um yeah...

cheater.

 

seriously the cams aren't stamped? i know my engine is different but i coulda swore the cams were stamped PM7 on the ends (DOHC ZC black top). maybe i was thinking about the cam gears...

 

yeah, like i said, stampings are on the cam pulley, not the cam itself. pulleys are the same, so no different.

Just incase nobody caught on yet... You cannot see the difference between the too unless you use tools or your so in love with d-series cams that you can measure it with your eyes....

NO identify marks/numbers

 

Sucks for me I guess then. Lol. Well, I'll be able to see the funny lobe if there is one, so that will be in my list of inspection when I meet the guy. Now here's the question do to my curiosity that may help my situation more.

Do any of you guys know what stamped head (pm7/pm6/pm whatever) contains a ZC cam? I'm sure my d16a6 head is stamped pm6. And the guy I'm getting the zc cam from has it still in the head... So hopefully that will help me determine it more with your guys' info! So if his stamped head is a ZC stamped head... then most likely the cam would be a ZC cam and most likely I'll take the risk of buying it.

So yea, we'll see where that gets me. Thanks for info and advise so far guys.
