Here is some good evidence that we will not be able to use the flywhee= l in place of the flex plate.

On this page at Mazdatrix, scroll down until you see the tools labeled= "flywheel stopper"


Note that one of them fits the non-turbo flywheel BUT NOT THE AUTO. = =A0And the other fits the turbo (Which I assume is different than the n.a. = auto since they don't list it there either). =A0We may be stuck just tr= ying to beef up the existing flex plate.
