zc cams work in d16a1??

[91civichatch]

One of my friends just bought an 86 tegra and I was wondering if the camshafts from a zc would work in his engine, I don't know that much about the zc's and a1's so I'd figure I'd ask before I told him anything. I also heard that the camgears are different and that I could get adjustable camgears for an f22 accord engine. I don't know if any a this is true so yea if anybody knows the help would be appreciated. o yea and how do the zc's/a1's respond to nitrous??

yea they would work.the zc has more aggersive cams then the teg motor.ill be finding some 89 teggie cams so i can send them to delta for a regrind.

web cams makes some pretty mean regrinds also my friend darren had good times on his stage 2 nitous cams he had made for him by web...delta also make a good one but i had one and it broke my head it was to much for stock v/t the delta was on my sohc non vtec. darren had b series cam gears i think his where adjustible. the jdm ZC's have alot smaller cam gear than the usdm on i think.

there may be complications, depending on the year of the ZC cams.

88+ EF type ZC cams will require you use the D16A1 cam sprockets and the exhaust cam timing marks will not line up. if you use a 5mm pin punch and line the cams up with the holes on the #1 cam sprockets it will set the cams at (or very near, depending on if your head/deck was milled and HG thickness) tdc.

why do all that when jg makes cam gears for the zc.i think hls still has a few left for the zc as well.u can find the dohc zc aftermarket parts just got to know where to look.

using cam sprockets (they are sprockets, not gears) designed for a ZC will result in engine damage on a D16A1 before the first cylinder fires. (cam timing will be off by ~10 degrees by the end of 1 full turn of the crankshaft, ~20 by 2 full turns, 30 by 3 full turns, etc).

no they are cam gears not cam sprockets. a sprocket has pointed teath kinda like a bike usly uses a chain.. and ifu change the cam gears u need to change the crank gear and pully.

nope. they are sprockets. a sprocket is anything driven by a toothed belt or chain. gears are DIRECTLY driven (like the gears in your transaxle). a pulley is driven by an untoothed belt or chain (like the alternator pulley).


you can't use a ZC crank sprocket on a D16A1 crankshaft. the crank snouts are different diameter. if you use the ZC cam sprockets you have to use the ZC crankshaft, too.

hmm u make a good point but no one really calls them that even on my alldatapro.com account it is called a cam gear/sprocket. I think it got it's name due to what it looks like. but i would have to say u are right on what it should be due to the fact of how it works.

incidentally, with an air-cooled VW, it really IS a cam gear :)
another unusual thing about that engine is that it is a 4 cylinder and there are 4 cam lobes TOTAL (2 intake, 2 exhaust). there are 2 lifters per cam lobe. This is only possible because the engine is both horizontally opposed and pushrod.


but I digress. At any rate, the point is the crankshaft and cam sprockets need to come from the same engine. otherwise ZC and D16A1 camshafts are interchangeable. if you mix sprockets & camshafts, the timing marks won't line up. the dowel holes in the cams will set the cams to TDC regardless of head/block/cam sprockets/crankshaft combo.

hey guys thanks for all the info on this my buddy bought some "nippon" camshafts off of ebay for his a1 do you guys know if these are any shit? has anybody had any experience with these cams? thanks for all your help already

[DOHCef8si]

there ok stage one i think he wont have to change springs or valve,although it would help a great deal to upgrade them too.and i still say its cam gears?or sprockets.i seen site call them both names.anyways i would use anything other then jg for zc.imo

Just put the D16a1 camgears on the zc cams in the d16a1 head (using the dowel pin holes to align the cams as Shadowboy rightly pointed out) and be done with it.
It works vise versa so it should work the way you want it to, I have browntop cams (should be the same as your A1 cams) in a blacktop head at the moment and it's fine.

[cvic90]

I had the black top ZC cams in my 87 teg motor. used the a1 "sprockets" and timing marks and it ran great.

[91civichatch]

Would you run adjustables with stage 2 cams? I don't know I guess he'll probably end up using the a1 gears for a little while until he can afford some adjustables.
