d15vs d16?
use a z6, it's a way better block/bottom end than the d15 will ever hope to be. also the y8 head works great to a certain point but the z6 head outflows it considerably and will make more power easier
but yeaah i know the z6 is beast....and know about the z6 head also but i did port the y8
The y8 will do fine, but the z6 head will still outflow a ported y8 head cause of the type of ports
