ok so ive been reading up on all this piston hype......and how some say its only better due to the low *** c/r, which seems true but the metalurgy seems much better also......anyways what would i be lookin at as far as c/r with an a6 block and y8 head with stock hg? from the d series compression calculator i used an a6/y8 combo yeilds around 10.8....and it seems that the pistons drop the c/r around a full point so would we be talking 9.6-9.9? that seems much more useable for turbo to me than the 8.0 c/r im seeing people have with those pistons in other d-series setups.......i may be talkin out my *** but a decent c/r with stronger pistons sounds good....

I think the difference to a good set of aftermarket would be well worth the extra scratch. Cast is cast and it will fail. my.02

true, but im just lookin to run 10psi daily.....i could tell you more but they seem good for a rebuild

w3rd. Vitara's drop your compression way low (something crazy like, 5:1) so when you're boosting 20 psi, its running the same HP/TQ as another guy running 10 psi on stock internals I completely agree with ghettoturbo here, save your money and do it right

EDIT: just read your last post.. run 10 psi on stock internals. Should last ya a while :P

dohc

i agree....but i plan on rebuilding an a6 block......and i have a y8 head.....and vitara's seem to be stronger and pretty cheap too.....

Dr.Boost

I doubt it would even run at that low of compression. :P It puts you in the high 7's-low 8's depending on your motor.

they're not too bad in a z6, about 8.5:1 comp.

the y8 head and y8 head gasket will bump the compression to 10:1, so those pistons will drop it back down to.. 9:1 or 8.5:1 somewhere in there.. sounds good to me.
