Hi.. Im haveing a hole bunch of probs with my motor right now.. and i thought i had a stock d16z6 motor and i was missing a dizzy so i got a brand new d16z6 dizzy and it doesnt fit right and its throwing codes.. My friend said he thinks i might have a d16y8 head on my d16z6 block.. Is there any Way to tell if its a d16y8 head?? Is there anywhere on the head theres numbers or something to tell witch head it is?

DopeEJ1-510

Dont mean to bump so soon but.. little more info..
I have a 94EX coupe.. runing a stock p28..
And i know its a z6 dizzy.. and i got it to fit but its kinda backwards and it started up but was back fireing a little... The Main thing im trying to figur out is, "How to tell if its a d16y8 head".. and what dizzy would i use if i have a d16z6Block and a d16y8 Head?

there should be some casting numbers on the head. that is the date. but i think it reads day/month/year.... not.... month/day/year. if its the same as the DOHC motors you might have to remove the heat sheild to see it.

Look on the cylinder head above where the exhaust manifold/header bolts to the head and there should be a year stamp on the head that looks like a circle with two numbers and a slash, like this:

9/2

If it's a 92 head it'll have the 9/2; 98 head would be 9/8, etc. etc.

If the marks indicate 9/6 or up then it'sa Y8 head. 9/5 could either be a late Z6 head, or an early manufactured Y8 head, with anything 9/4 and lower definately being Z6.

100% correct.

Ok.. So i just looked and theres no slash or circle.. But to the very right side of the head It says 97... in big numbers... so im guessing its a y8 head?.... Also knowing that its a y8 head now.. witch dizzy would i have to use for it to run right? wiring and such..

Also thanks for the help..

Does the engine harness you have have one big plug for the distributor, or one big plug, and a smaller, two wire plug that has a black/yellow wire and a blue wire?

DopeEJ1-510

The Harness i have has 2 plugs.. One Big plug and one smaller plug, and Yes the smaller plug has a Black/Yellow and a Blue wire..

For this post dizzy = distributor

Well if you in fact have a Y8 head then you will run into a problem with the dizzy.

The Y8 dizzy will have one big plug with two fat wires at the bottom of the plug - one black/yellow; one blue - these wires will need to be pulled out of the plug.

Now cut the two pin plug with the black/yellow and blue wires off of the old distributor

Now take the wires you pulled out of the fat-*** Y8 dizzy plug, and solder them (match the colors of course ) to the plug you just cut off of the old distributor.

You see the OBD1 harness and Z6 dizzy have a two plug style, while the Y8 is OBD2 and only has one big plug - check these pics:

you can see the blue tape where I have had to add the "extra" plug onto what used to be an OBD2 dizzy to make it work with an OBD1 engine harness:



...and here's the two wires you pull/unpin from the OBD2 style dizzy plug:





You need to make 100% certain that you in fact have a Y8 head, and that the Y8 dizzy base bolts up perfectly to your head BEFORE you go cutting/pulling wires out of the new and old dizzys.

Ok.. Thank you VVERRYY Much.. this helps alot.. Im going to try and get my hands on a y8 dizzy and see how it goes..

I will post as soon as i figur it out.. Thanks again..

BTW:

Make sure that the cap/plug wire order is correct, or else that **** is going to run like ****.

Also make 100% sure that the distributor shaft is indexed/turned correctly to line up with the keyway on the engine's camshaft. You can "force" the **** to go in 180 degrees out and it'll feel "almost" in there, but if you try to tighten it up it can snap an ear off the dizzy, or worse, damage the camshaft where the dizzy locks into it. the cam and dizzy have a certain taper to them where they fit together and sometimes it's hard to see it.

Maybe someone can post detailed pics of how the distributor bases look to compare them...

Hey you know what? What's the part number on your old distributor? does it have a "TD" part number?

For reference the stock part # for a 92-95 Z6 dizzy is TD42(U). The base has three ears on it, with two almost beingstraight across and the one ear sticking up. If looking at the base side the ears make a kind of lower case y shape.

The stock part # for the Y8 dizzy is TD80(U) and the ears look more equidistant from each other almost making a perfect trianlge or tri-point symbol like a Mercedes Benz look to them.

Lastly you can look up "Distributor King" or "richporter technology distributors" on E Bay and of course find them for 92-95 Hondas with the Z6 motor, and then the 96-00 Y8 Hondas and compare pics of them bases to see what you need.



I suck at Ebay, but I know you should be able to find clear, close-up pics of the two various dizzys. Hell the part numbers will certainly come in handy.

Hey.. Just wondering I was doing some searching on another website and Alot of people with the same setup as me said a 92-95 DX dizzy works for my setup.. What do u think about that?

DopeEJ1-510

Anyone know about the DX or VX or LX or any non vtec Dizzys working with my setup?

DopeEJ1-510

Someone please, Tell me If i can use the DX dizzy

pynikal

why do you want to use a non-vtec dizzy on a vtec car????

I dont think vtec has anything to do with the dizzy.. Its just that it fits correctly...

DopeEJ1-510

Ok so i got a y8 dizzy and here some pics of the yellow/black and only solid blue wire i pulled out.. for some reson i think its wrong thats why im posting pics..

So im just makeing sure i pulled the right wires out of the clip befor i start cuting..

This stupid dizzy **** is never ending..

B18C5-EH2

That is weird. Evidently the B series dizzy has a compleely different plug on it than the Y8 one.

You could always try to unpin the two wire plug (seen in your second pic) and connect the black/yellow wire from the engine harness to the one you pulled fro the Y8 plug, and conect the blue wires and see what happens.

...at least you didn't vut the wires - that's a good thing.

DopeEJ1-510

I connected the Black/yellow wire and the blue wire.. and It just turns over but no fire...

DopeEJ1-510

I dont under stand why its not working..
im about to set my car on fire im so frustrated...

akmi_1

YES U CAN! u should be able to use the Dx, Lx, Ex dizzy on pretty much any d-series head.

i have built a bunch of mini-me's and by what i have read...i think ur wiring might be wrong or the spark plug wires/cables might be in the wrong order...

lmk what u find...

pynikal

what is it doing...with both dizzys????
