I’m wanting to know if this was true. I’m looking to rebuild my zc but don’t know what parts to get. A little lost here. Any help would be great!

pictures of your engine

Yes it is VTEC

 

[Evanguy]

All Dseries are "ZC" motors

There is obd0(A6)
There is twin cams
There is OBD1 vtec and non(z6 and d15b nonvtec)
There is OBD2 vtec and non(y8 and y7)

 

[slo_eg8]

looks like a z6

 

[Evanguy]

If it looks like a z6 its an "obd1 vtec ZC"

 

[Mache]

If it looks like a z6 its an "obd1 vtec ZC"

So we sayin buy parts for a z6? I thought ZCs had more of an aggressive cam than a normal z6.

 

[Evanguy]

You mean the obd1 vtec zc has a more agressve cam then the d16z6? I dont think, i think its more agressive ecu. And thats why most JDM motors make 10 more hp then the NADM motors.

But yes you will want parts for a Z6.

Im assuming it has a obd0/1 cam gear on the cam?


Every single D series engine in the JDM is called a ZC. Best not to use it to deiscribe the motors.

Saying "ZC" is the exact thing as saying "D series engines"

If you are going to use "ZC" you need to say the obd number and vtec or not.

Same as if you were going to use "D series engine" you would aslo need to say the obd number and vtec or not.

Other wise you are just talkikg about a Series of engines built by honda not a single engine.

why do I feel like I went over this once this week?

the zc is a z6 with a bit and i mean a little bit more aggresive cam

everyone always acts like the cams are super different but theyre actually such small differences you wont notice a bit

Hey everyone.

I know... I know...

This has been covered a million times, but I want to make sure what I've read is correct. A ZC head with a few goodies has become available and I want to make sure that it will work with my Z6.

If I'm not mistaken, the SOHC VTEC ZC is essentially the JDM version of the USDM d16z6, in which case it should work with my z6 (P28 - chipped).

Can someone please confirm this?

Sorry again for the extraordinarily newbish question.

Thanks.

Before doing anything, you need to remove the valvecover and look inside.

The non-vtec ZC engines cam in all sorts of styles from the 80s to 00s.

Yours could easily be the one that is similar to a d16y7 nonvtec. Just because it has a vtec valve cover, doesnt mean squat.

I will take a picture just for you boss.

Sorry. 😢. I’m a newbie.

D16a1?

 

[bumpstick]

Does it have a VTEC solenoid? Does it have a code cast on the head? Post a pic of the cam

 

[mattliston]

d16a1 is dual cam, so no.

Likely says "AT" as in automatic transmission.

Picture of the valvetrain guts will show the scoop

 

[TheIronGoat]

its says vtec right on the valve cover and zc on the stamp plate = zc vtec so you can immediately rule out the d16zc non vtec = d16a6 because you have an 0bd1 sohc vtec zc which is the same as a d16z6.

 

[mattliston]

With that head style, it does not matter if it says vtec on the valvecover, the d16y7 and d16y8 share the same casting externally.


Presence of a vtec solenoid would be the indicator.

Internally, whether it is a rocker or roller arm style will determine if it is normal vtec or economy vtec, if a solenoid is present.

I miss my zc non vtec ... so easy to find parts for and smokes z6 all day... just not off the line

Heres the scoop. Apologize. Have been busy. But we got pictures guys.
