Y8 pulley on Z6, is there an easy way to correct the distributor timing marks?
I tried holding them ontop of each other and I feel like it's just not exact enough to transfer the z6 crank pulley's markings onto the Y8 crank pulley.
I also considered adjusting the distributor by ear / feeling instead of using a timing light, which I may (maybe not) need to do anyway since the surfaces were milled 0.016.
Is there an easy way to copy the z6's marks onto the y8 crank pulley? Short of machining a rod that will align them..

The original z6 pulley was damaged at the junkyard before I got the engine home, along with the oil pan and exhaust manifold. Everything is completed and double if not triple checked to ensure quality control.
I would just like the option to use a timing light, despite my ability to time the engine adequately without that tool. I've read that I'll need to adjust the distributor again once I install my 46mm turbo but for now I'd like the option to use a timing light.

What makes you believe that the marks are different ??? If it is because the Y8 marks appear farther apart... it is because the crank pulley is LARGER in diameter than the Z6 pulley. Place the engine at TDC with the damaged Z6 crank pulley, remove it and replace it with the Y8 pulley. The timing marks should be aligned.

Re: Y8 pulley on Z6, is there an easy way to correct the distributor timing marks?
my first clue was that that my z6 pulley had 5 marks and the y8 pulley only had 4. I'm gonna find someone to hold my pulley holder tomorrow so i can get it off and photograph the inconsistencies between the two pulleys. I'm pretty sure i'm correct about this, i don't think i would've made a note of it if they were exactly the same.
And you're right, the y8 pulley has a slightly bigger lip on it. Made putting the alternator belt on rather difficult, had to turn the pulleys to get it over the lip, but i'm pretty sure that the diameter of where the belt makes contact is the same.

In theory it should. With a larger diameter pulley there is also more parasitic draw though. Does the Alternator pulley need to match the crank pulley?

Not sure I understand your logic. The alternator charges fine over a wide range of engine rpms.

Re: Y8 pulley on Z6, is there an easy way to correct the distributor timing marks?
My engine only has one accessory, the alternator. I may install AC eventually though.
I'm pretty sure the actual diameter of the pulley where the belt makes contact is exactly the same. The difference is a lip at the edge of the pulley's biggest thingamaging. I suppose it helps keep the belt in place. A belt thats a little bit longer would make install/removal of the belt a lot easier.
I use the powerbuilt pulley holder, but my engine is on an engine stand so it's significantly more difficult to get the pulley off. Normally I jam the ratchet against the LCA and then turn the bolt out, I can't do anything like that in this situation.

I've read that the D16Y8 Pulley (OBD2 96-00) uses a 12 degree ignition timing where the D16Z6 (OBD1 92-95) uses the 16 degree ignition timing.
Your best solution is to measure the circumference of the pulley, then do the math so you can paint the 16 degree BTDC mark yourself.

How much do AEM pulleys change the stock ratio of the crank pulley diameter to the alternator pulley diameter?

$130 on Majestic for the guaranteed right part, out of the box, with no ghetto rigging involved. Or pick one up from a scrap yard. Or a new one off Amazon for $75. All of this shoehorning is just silly when the proper solution is right there.

I would hardly consider that the best solution.

It was actually what I was looking at doing as Z6 pulleys are hard to come buy at the scrap yards but there is a plethora of Y8's.
As far as I know, their are pretty much identical with the exception of the ignition timing marks.

What's important to maintain is the ratio of the crank pulley diameter to the alternator pulley diameter. I assume that they're very close and, if so, there should be no charging issues.
Voltage and amperage are intimately related through Ohms law. Changing one, changes the other. The voltage regulator increases amperage output when the system voltage drops.

Never messed with one, only from reading.

If you have both pulleys you have 2 other options. 1) you can put on the z6 pulley, set the engine to the 16* mark, then swap on the y8 pulley & mark it; 2) set both on a shaft with the same sized keyway, put both on it and copy the mark.
The real question I have: why are you so set on using a y8 with z6 marks when you already have a z6 pulley to use?

y8 pulley is better in general. smaller in diamter, it has a smaller centripetal force , i think i read it has a better damper on it too.
take a small file and scribe in too marks further passed the 12 and 14* marks approx the same distance apart from each other. I did that on the y8 i used on my dohc zc
