Here's the problem......I bought all the parts to assemble my d16y8 (pistons/rods/bearings/studs) and the block threads are messed up for the head studs. I was going to transfer all the parts to the spare z6 block I have......are the pistons and rods the same size? or will the y8 internals not work on the z6??? Thanks for the replies.

are you using y8 or z6 head??

 

I have a z6 head......I bought 9:1 comp pistons for boost.....if I could use them, would my comp. ratio stay the same?

 

if you use the stock y8 pistons and use the z6 block and head your comp ratio will go up to 9.8:1 from 9.1:1

 

what factor will change the compression????

Also, you have AIM I could talk w/ ya on for now???? thanks

 

no got msn messenger just by changin the piston will up compression because they are not dish as much

 

IMO, I'd rather go w/ 9.8:1, you will see more power at the same boost level. What's wrong w/ that?

 

Well I have aftermarket pistons (srp 9:1) pistons made for the y8......if I take those pistons and rods for the y8, will I have any trouble w/ clearences or anything? And will the comp. ratio still change since they are aftermarket?

 

well if you use those 9.1 pistons there shouldnt be any change in the comp ratio and im not sure but i dont see any problem with clearences
