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.

 

no one else has done this motor combo? come on

 

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

 

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?

 

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

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

z6 head, z6 belt.

its that simple.

 

z6 and y7 belts are identical.

Along with y8 and y5.

 

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

 

All 4 are the same.

Its as easy as counting the teeth.
