I tried swapping my D15b7 Non-vtec head on to my D16y7 block. Everything was going just peachy until I started to put the Timing belt back on. It seemed as if it's too short/small....

Now I know you're probably going to ask why did I swap heads... The D15b7 head is fully port and polished and milled... So my question is what could be going wrong? Do I need a dif. Timing belt? Is the head taller then the other?

TIA

prolly d16a6 timing belt is what you are looking for. Don't know too sure, but there aren't too many people going from vtec to non-vtec.

 

I didn't go from VTEC to non VTEC... both heads are from a non vtec block... is the d16a6 vtec?

 

I just don't understand it all?!?!?!? Is the D15b7 head taller then the D16y7 head? They both share the same head gasket and everything..

 

?

 

if the belt you got right now is too short i would probably assume that hte new head is taller, seems logical i guess. Anyway i owuld compare to teh 91 crx si timing belt and see if that one is long enough to fit.

 

that's what I'm thinking... I might take the belt off today and take it to honda to compare belts and what not...

 

b7/a6 belts are longer than z6/y8 belts.

Its been a while but I think z6 is 103 b7 is 105.

Like I said. Its been a while since ive counted.

BTW you put oversized valves in that b7 head ?

no, the valves are the same size.. Do you think 2 teeth would make that much of a differance... By the way do you know how many teeth are on the y7?

oh I read d16y8 for some reason, are you sure you didn't edit that?
But yeah hit up autozone or something and compare belts.

LOL yeah you did read Y8 but I thought I had put Y7.. I edited it after I posted after you... LOL sorry... Well I ended up buying a CRX si belt... IT's got 107 teeth, where as mine stock came w/ 104... i'll keep you guys posted to see how everything works out...

 

z6 y8 y7 belts are all the same.
I assumed u knew that.

Hell I was close as far as the tooth count.

Just fyi. A half tooth is equal to about 4.75 degrees. Add it up.

Not doubting you or anything but where do you get that? I would like to know just for my own info... This is all I was gonna do... The belt was to short so I was going to just get a belt that will fit like it was supposed to... I'm going to make sure the head is TDC and the block is TDC before I mount the belt... How does that sound? thanks

im pretty sure for single cams u match the t-belt with the head.

Everything seems to be alright... Knock on wood... Now does anyone know where to find a decent NON vtec cam?

 

Delta, Crane, comp, crower, exospeed.
Plenty of choices for the a6/b7 head.

The cam degree info is just some stuff from a GREAT old sohc forum.

 

Oh ok.. cool thanks a lot.. I haven't really been able to find anything for the NON VTEC heads... LOL

 

Youll find more for the a6/b7 head than any other sohc D head.

Good luck with your project dude.

 

cool, thanks

 

you need the timing belt for the head that you are using, you might also need an aftermarket cam gear to get the timing perfect. GL hope this helped.
