One more indicator for different ring gears. I just got a new RX7 starter motor for the single rotor. The question was "turbo or not turbo", and the listing showed for the turbo starter 13 teeth and 12 for the non turbo. The lay out on the single rotor is for a turbo starter because that was what I had when I started out. Is the turbo RX7 cranking slightly faster than the non turbo?
The tooth profile is the same.
FWIW.

Here is some good evidence that we will not be able to use the flywheel 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.  And the other fits the turbo (Which I assume is different than the n.a. auto since they don't list it there either).  We may be stuck just trying to beef up the existing flex plate.
