bauley: "Read up on the Y7 and Y8 pistons...the B7 pistons are flat and the Z6 ones are dished, so the B7/Z6 mini me's have a 10:1 ratio. Both the Y7 and Y8 pistons are dished, the Y7's actually having the larger dishes, meaning less compression. A Y7/Y8 mini me will have lower compression than a stock Y8."

:thinking: could this be tru?
