y8 cam w/ z6 sprocket, z6 cam w/ y8 sprocket

[builthatch]

This comes up alot, so here is a quick breakdown-

If you put a y8 cam in with a z6 gear, the cam keyway will be lined up with zero on that gear and retarded about 4.5 degrees. in order to correct this, you want the keyway to be 4.5 degrees away from the z6 original keyway position, so you would ADVANCE the y8 cam w/ the z6 gear 4.5 degrees. This would now make your y8 keyway 4.5 degrees to the left of the straight up and down 'typical' z6 keyway position (if looking at the cam gear face).

so, if y8 cam w/ z6 sprocket: advance 4.5 degs. If z6 cam with y8 sprocket: retard 4.5 degrees.

Finally.

So, y8 cam in my z6 = advance 4.5*. Thanks.

yep, y8 cam with z6 gear = advance 4.5*

OK so let me get this straight. With y8 cam into the Z6 motor and a Z6 adjustable cam gear. I set motor to TDC on the crank and lined up the cam gear(still set at 0 degrees) with its TDC pointer on the cam cover. Then just simply advance the gear from there 4.5 degrees, and recheck ignition timing? Do I got it?

what if u have an a6? i have an aftermarket (rage racing) cam gear for a a6 but am concerning doing a y8 mini me, what setting should i use to start out?

a6 i think is like a z6- keyway inline. not 100% sure tho; it's been a LOOOOOOONG time since i've had an a6 (1997)

Ok, so you can use the Y8 cam in a Z6, or a Z6 cam in a Y8 if you adjust the timing????

Or is this just for using the different cam gear??

either or- just have to adjust the timing to match as if it had the right cam gear.

i have a z6 adj. camgear on a y8 minime..adjust 4.5 advanced or because i am using a d15b2 block other?

Ok, so let me see if i got this. im planning on building a Z6 bottom end and putting a Y8 head on it. So to make up for the timing differance i can just get a Z6 cam gear on my Y8 cam and advance it 4.5 degrees and everything should run fine??

yep...or you could throw a y8 gear on there and adjust nothing, but if what you have is a z6 gear, then you are correct.

[eg95-n/a]

but can u fit the y8 distrubutor on the z6 with no problems while haveing that ? or can u just put the y8 distributor?


thanks

Ive been looking around but still dont know what to do really...I have a d16y8 head. BUT I just picked up a Crower stage 2 cam for a z6 at a really good price.

My question is, if I run this z6 cam in my y8 do I run the y8 cam gear or the z6 cam gear? I thought the z6 and y8 cams were identical, so does this mean I just run the y8 cam gear and the timing should be straight forward?(with a aem cam gear) Thanks in advance!

on a d15 block does the above info still correct or are different settings required? just want to be sure i have NO piston to valve clearance issues thanks

Ok. I have a b7/z6 mini me. I have a crower stage 2 z6 cam...do I still use the y8 gear to correct the timing problem with the mini me's????

Please reaffirm this to make me feel better.

use the distributor that matches the head; you can change the insides of the distributor so it works with your setup (meaning putting z6 insides into y8 distributor, or vise versa), or get a distributor conversion harness, but the easiest thing to do is keep a matched set when it comes to head, cam, sprocket and distributor

match cam with sprocket...but if you can't, you can use an adjustable from the wrong year and adjust it according to my chart.

so, if you have a z6 cam, use a z6 sprocket. if you already have a y8 adj. sprocket to use with that z6 sprocket, then adjust accordingly.

you will need to search about difference with deck heights and how it affects thing with the d15/d16, etc, because honestly i can't recall much about mini-me's w/o refreshing my memory doing the same thing you can do (search)

if this is what you normally do with a b7/z6 mini-me, then it would stand to be true for a performance cam, since the keyway will be in the same position for the Crower z6 cam as it would be for the stock z6 cam. again, i don't recall much about mini-me's- i studied them at one point, but since i never put one together, it didn't sink in like the straight forward 1.6L vtec builds have.

I got a Y7 and Im using a Y8 gear are they the same? Do you know?
