y7 block with z6 head
 

im just wondering if i should use a z6 timing belt or a y7. i used a z6 last year and it seems very very close but still really loose( like it bottomed out the tensioner before it was snug). Im gonna be tuning on the 12th and i wanna get everythig prepared.

Re: y7 head with z6 block
 

I thought that you always matched the D series timing belts to the head? ???

Re: y7 head with z6 block
 

thats what i thought too, but when i used a z6 belt it seemed to long. does the y7 one have a few less teeth?

Re: y7 head with z6 block
 

well from reading your thread title. I assumed you have a y7 head, and was using a z6 belt on it... :8

If you have a y7 head, use the y7 belt.

z6 head, z6 belt.

its that simple.

Re: y7 head with z6 block
 

I thought that the y series heads all shared the same castings. I use a y5 head on a z6 block with the z6 belt.

Re: y7 head with z6 block
 

z6 and y7 belts are identical.

Along with y8 and y5.

Re: y7 head with z6 block
 

Wait, are you saying all four are the same or that z6=y7 and y8=y5 and both pairs are different from each other?

Re: y7 block with z6 head
 

im sorry guys i was bein ------ retarded, i have a y7 block with a z6 head. but yea.

Re: y7 block with z6 head
 

All 4 are the same.

Its as easy as counting the teeth.
