Subject: [FlyRotary] Ok Here are the important flywheel measure= ments

I finally got to the hangar and measured out my S5 t= urbo flywheel and the remains of my S5 flexplate.  The results are ver= y encouraging, even as good as the possibly could be to make the swap, but = I only had ten min at the hangar before I had to leave to pick up my daught= er from daycare, so they are one try and slightly sloppy... I make no guara= ntees.  The height measurements of the flex plate were particularly su= spect because, well, mine is all warped and broken.

Ring Gear Dia= meter - Perfect fit.  As we suspected, same size, same tooth spaci= ng.

Ring Gear Fore-Aft Placement - As measured from the under= side of the big nut. (for all further reference, aft means aft in the CAR).=   The flex plate puts the aft side of the ring gear 1.290 inches from = the front of the big nut. The flywheel puts it 0.913.  So the flex pla= te puts the ring gear (appx) 0.377 in. further aft.  This is actually fortuitous because it just so happens that the ring gear thicknes= s is .365 ...    So all we have to do to fix the discrepancy= is weld and extra ring gears onto to the flywheel ring gear and there will= be teeth that the starter can reach:(bottom of the page.. the cost $80)http://mazdatrix.com/flywheel.htm
It may also be possible to fix = the discrepancy by changing the starter... will look into that.

D= amper Plate Placement - On the flywheel, the mounting surface is proud = (or aft) of the ring gear.  On the flex plate, the mounting surface is= recessed (or forward) from the ring gear. And it all pretty much works out= .  That position on the flywheel will vary somewhat depending on which= flywheel you have and how much wear you have on the clutch slip surface. B= ut on my (I assume well-worn) flywheel the placement was 0.965 while the flex plate was 0.950.  Pretty damn close and given measurement error = it might me meant to be right on.  Or, any difference could be made up= by trimming down the spline on the damper plate or removing or adding spac= ers between the two.

So in my mind, a flywheel is the way to go.&nbs= p; Stout, easy to get, pick your weight, only mods seem to be drilling the = mounting holes and welding on a second gear ring.
