yeah 2mm greddy gasket will lower ur compression one point Ex. 9.5:1 to 8.5:1. thats what i calculated on tht compression calculator thingy tht was up here a while back

Re:lowering compression
 

thanks. do you know where is the best/cheapest place to find em

Re:lowering compression
 

i just checked out that knology site.. the d16y8 pistons w/ the stock gasket drops to 8.2 but the .078" gasket and stock pistons runs 8.5. the negative dome in the y8 is bigger.

Re:lowering compression
 

does greddy make a 2mm metal head gasket for the zc?

i can only find d16a6 ones.

Re:lowering compression
 

Good call. They don't even make them. :-[ Sorry man. Got your hopes up for nothing. Someday soon they will realize there is a demand for them and start producing them.

Put Z6 pistons in an A6 block/head, or bolt a A6 head on a Z6 block... 8.4/1 compression. Or you can stack 15 head gaskets...

How much boost could u safely run with a 2mm gasket
on a y8?
