D16a6 Compression
Is there is a rule of thumb:
I am doing a d16a6 rebuild and am wondering what a safe/reliable compression ratio is? I know stock is 9.1:1. This is for an everyday driver and NO future plans to boost.
I was thinking about keeping the stock pistions, using a Y8 head gasket, and milling the head.
I am not sure on the recommended amount to mill the head?
Any info is appreciated.
Thanks.

think a z6 head gasket would be better for boost if I am correct and I wouldnt mill head to much Just tell shop to clean it up...boost dont like high compression...milling head will start bumping it up

that looks good. the only problem i know of with milling the head is if you to too far, the cam timing gets off adjustment a little unless you get an adjustible cam gear and install it a little off in the direction you want.

I came up with 9.7:1 using the http://www.zealautowerks.com/dseries.html
So the mill of .03 and a Y8 headgasket = 9.95:1
