Are the A1 pistons better in a Y7 with a Z6 head? Or is it the A6 pistons?

D16A1 pistons are for DOHC, if you put them in a single cam, off the bat you're looking at around a 12:1 CR. Depending on the head, and headgasket you run, you can get around a 13.1:1 CR.(Y8 block/Z6 head)

wow ^ you have no idea what your talking about.

a1 pistons in a y7 block with a z6 head and a y8 head gasket will yield you about 11.6 comp ratio...http://www.zealautowerks.com/dseries.html

More like 11.6:1

ok so I didnt have the CR ratio off the top of my head perfect from a setup I've never owned. I however have owned a 13.1:1 Y8 block/Z6 head combo.

Regardless he isn't talking about A1 pistons unless he wants a beast all motor setup, which doesn't seem that way.

So maybe you shouldnt make posts acting like you know what the fuck you are talking about?

so can we get back on topic real quick and then you guys can duke it out. i know the a1 pistons are DOHC but i thought they where the same bore. they came in the 88? tegs right. and the a6 pistons are the 88-91 crx si. i was just wondering which one would be better. im getting ready to pop the head off but before i put the z6 head on i just wanted some info on it. thanks.

if you want higher compression. go to the site that the other guy and I posted. play with the 2 you have in question. for all motor sohc high comp the best pistons are p29. but im pretty sure the pistons are the same size 75mm
