I am currently in need of a crankshaft more my motor buildup as some of you have heard already, and I have the chance to pickup a D16A6 long block. The motor I have sleeved already is a D16Z6 block, literally the bare block. Can anyone tell me if there are any differences between the D16A6 crankshaft /mains and the D16Z6 Crank and mains. If there are any differences that you know of, can you go into them in detail?

Areas of concern -
Oiling
Oil Pump mounting
Main clearance for oil pan
Main construction and material used
Etc

 

Some information I've found

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">I've read a couple little comments from Larry Widmer and on Honda-tech about the A6 main caps being made of steel while Z6s and everything else all made of a weaker aluminum. I was wondering if anyone knew if A6 main caps would fit on the other blocks. Sounds like a cheap way to keep things together a little better in those high-horse applications.</TD></TR></TABLE>

So you COULD use a A6 crank in a Y8, but you'll never be able to time it correctly Since you'd have to use a Z6 crank pulley.</TD></TR></TABLE>

This is telling me that the A6 crank and the Z6 crank have the same snout diameter.

AND FOR THE WIN on the Crank issue

he has a build sohc stroker, and knows a lot about which crank/crank pulley to use on a lot of the sohc setups.

i was alwasy under the assumption that a6/z6 cranks were interchangeable
