The reason for this is that the turbo cars have a much beefier clutch and transmission. This is also why it needs a different starter and has different teeth. Also, the stock flywheel is balanced differently from aftermarket flywheels. The aftermarket flywheels use the same counterweight as the auto transmission, and swapping the weights around is annoying, so that's another reason to not use stock flywheel. As for whether the manual flywheel could be used in place of the flex plate, I don't know as I don't really understand how the PSRU hooks up. I know the flex plate is different "somehow" as it takes yet another kind of starter.

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.
