Default Re: i have a quick y8 question (nihad)

If you do a proper search, you'll find that the a6 block with y8 head is a pain in the ***. I'm in the process of doing it right now. Read up and search.

When people tell you to use the timing belt, the tensioner, the head bolts to just match the head, they are wrong. I already bought a y8 timing belt for NO REASON.

If you want to use a z6/y8 timing belt, you have to use a z6/y8 tensioner and that just doesnt fit on an a6 block. You have to use an a6 waterpump, tensioner, spring. And if your using a y8 head, the y8 timing belt is WAY too tight to squeeze on there. You'll spend 4 hours trying to make it work, only to end up stripping something out. 2 years ago I attempted this swap with the wrong information and ended up stripping out the tensioner hole.

y8 timing belt = 104 teef = too tight
a6 timing belt = 108 teef = too loose

1992-1995 D15b7 timing belt = 106 teef = what you need.

Also, when you mate a stock y8 head onto an a6 block, you'll find the y8 camgear is retarded 4 degrees or one half toof. You can get away with running like this, but I hear it will run like ****. I purchased a skunk2 adj cam gear to advance the cam timing to make up for the 4 degree retardation on the y8 motors.

Next time search your *** off because Hondatech is starting to become majorly misinformed.

The 92-00 Civic forum has some of the best info from what I've found as they have done alot of mini-me swaps.

Default Re: i have a quick y8 question (HBK)

unlike some other misinformed people i did search and as you can see, information on mating the y8 head to a a6 block and which timing belt to use was all i was need. gosh, i wish sometimes people would just step back for a second and actually take the time to realize all someone is really looking for is and answer not a short "search" button or comment. it's real iritating when it's obvious and even though there's an answer and one's willing to share it. it takes pulling teeth for them/someone to give you a straight up answer...but

thank you!

&lt;- using a y8 t-belt on an a6/y8 setup with a6 tensioner along with my friend now with the exact same setup. I take off/install all my timing belts by hand (slipping them over the cam gear) so i know for a fact it's not THAT tight.

This doesn't make sense and is the first time i've ever heard this. If you use a y8 cam gear along with a y8 cam, how could it be misaligned? It has nothing to do with the block, you set it to TDC separate of the block.

Furthermore, full-race had this exact setup in their Pinks! car and on the dyno the motor made max power at 0 degrees. It was turbo but still points to this info being false. http://www.full-race.com/pink_sohc.php

I think your confusion here is based on the y8 and z6 pulleys being different. If you use a z6 cam gear on a y8 cam your info above would be correct but using the y8 cam/cam gear together there is no cam timing issues. I'd love to be wrong on this because i'd love to pick up some easy power on my car but i really doubt it.

I wasn't trying to bust your ***** about searching. I never tell people to search but I do try to help whenever I can. I'm just saying that I did alot of searching and kept getting misinformed. Everything else I wrote about was just trying to look out for you. I didn't HAVE to type all that **** out

It does make perfect sense, that as long as the head is at tdc, then there should be no problems. I was under the influence that I had to use an adj. cam gear and advance the difference that the y8 cam gear was off. Once again, misinformed by H-T Sorry about that. So all I have to do is mount the head, set it at tdc, set the block at tdc, then align the t-belt and hope for the best. I bought a skunk2 adj cam gear so I think I'm gonna run that for the bling-factor.

As far as the timing belt goes, I read that with a stock a6 tensioner, and y8 timing belt, that the belt would be too tight. Since I have both the y8 belt and the b7 belt, I'm gonna experiment with them both and see what fits best.

I apologize for the confusion, I wouldn't have typed that much originally, but after searching a lot I started to get frustrated seeing people say "match the head your using"

Heres the thread that got me thinking about the cam gear..and now I'm confused again

https://honda-tech.com/zerothread?id=1846913

If the head is set at tdc with stock y8 cam/camgear, and the block is at tdc then there shouldnt be a problem.

That thread is saying that its 4.5 degrees off, so I'm gonna install everythign with the adj. cam gear where the stock y8 cam gear was, and then tune as needed.

Well, I ran 15.5 (with a 2.3 60') with my current setup so I really doubt the powerband is that shitty and I don't know it. I just see no reason why it'd be offset, I think some people just got confused in the differences and misread and are now spreading misinformation.

I guess if the distance between centers was different it would change it, i'll have to get out the micrometer and check.

I wish I was going to the track soon because I have a cam gear on my car (set at 0 degrees, stupid huh?) and I would move it around but I'm moving back to Chicago tomorrow. Oh, and there is no battery in my car

I plan on installing the motor with the adj cam gear at -4.5 degrees (Stock y8 tdc) and see how it runs. Granted everything runs fine, I might try and adjust it to see what happens.

Its a possibility, that just becuase your car runs fine, doesnt mean its running its best ya know?

From what I've read on H-T, vtec heads are off timed compared to non vtec so who knows. The best way to go about it is with a dyno but eh...

edit: and with a y7/y8 motor in my 88 crx, I pulled a 14.7 on bald 13" tires so I think we could get alot more out of the best Dseries block, adn the best flowing vtec head and intake manifold.

I should put that 15.5 in context, a B16 the same night with bolt ons ran 14.9 at best and ran 15.2 average. Shitty track/weather. I was also using the a6 manifold at the time.

Either way though, I don't see why a y8 head would be off timing.

Yes Ive heard of others useing that setup too Im not sure what HBK is all fussy about.

I think the confusion may be over the cam /camgear itself. I Know there is a 4degree or so difference somewhere between the z6 cam and gear and the y8 cam and gear weather its the cams that are different or the gears im not sure. Hopefully someone will clear it up.

There is only a issue if you mix the stuff though. The cam and cam gear when used together is exactly the same.

I'm just frustrated by the lack of correct information using the search function. One person says one thing, and another says something else like its a fact. I take the word of whos done it. I still think there is more then one way to skin a cat, so we'll see what happens.

how many teeth is the z6 belt?

your saying to use the z6-y8 belt you cant use the the a6 tensioner. why?

What belt do you use when putting the z6 head on an a6?

does the 1.5 b7 belt work with the a6 tensioner?

letts just clear out all this stuff
