OK Kelly,
 
Thanks to all your hard work and research, I have ordered up the Prolite 9.8 lb version of this.  Dec= ided that I was done with the flex plates.  Thanks for locating a grea= t price.  I am a little nervous that the picture does not look right, = but I guess I can always return it.
Like you, I figure we will solve the starter issue one way or another.=

friction area is slightly raised (about 0.065) above the clutch = mount area and I would probably take it

        One other thing at th= is time..............The lighter 9.8 lb version may be usable but it is lis= ted as 116

        I suspect it may be t= he diameter of the NA 13B flywheels and may use the 86-91 NA manual tr= ans
starter............You need to talk to the manufacturer.........= .They are in Lancaster, Calif............The 9.8 lb
version is a little more expensive due to more extensive machine= work to reduce weight.............See the
link below............The link to THMotorsport= s has the best price I have found on the 9.8 lb flywhe= el......The
photo on their page is not the Rotary 9.8 lb version...........&= nbsp;

Dave and All,
 
         Sounds encourageing...............Replacing the sta= rter with turbo model would seem to be
least expensive and safer than adding additional ring gear + wel= ding..............I also echo what
Bill and Bobby have said concerning the Al Wick fix and getting = Tracy's thoughts about cause
of problem and perhaps need for periodic inspection and/or rubbe= r isolator replacement........

Subject: [FlyRotary] <= SPAN>Ok Here are the important flywheel measurements

I finally got to the hangar and measured out my S5 turbo flywheel and = the remains of my S5 flexplate. = ; The results are very encouraging, even as good as the possibly could be t= o make the swap, but I only had ten min at the hangar before I had to leave= to pick up my daughter from daycare, so they are one try and slightly slop= py... I make no guarantees.  The height measurements of the flex plate= were particularly suspect because, well, mine is all warped and broken.
Ring Gear Diameter - Perfect fit.  As we suspected, same s= ize, same tooth spacing.

Ring Gear Fore-Aft Placement - As me= asured from the underside of the big nut. (for all further reference, aft m= eans aft in the CAR).  The flex plate puts the aft side of the ring ge= ar 1.290 inches from the front of the big nut. The flywheel puts it 0.913.&= nbsp; So the flex plate puts the ring gear (appx) 0.377 in. further aft. = This is actually fortuitous because it just so happens that the ring gear = thickness is .365 ...    So all we have to do to fix the dis= crepancy is weld and extra ring gears onto to the flywheel ring gear and th= ere 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.
=
Damper Plate Placement - On the flywheel, the mounting surface i= s proud (or aft) of the ring gear.  On the flex plate, the mounting su= rface is recessed (or forward) from the ring gear. A
nd it all pretty much works out.  That position on t= he flywheel will vary somewhat depending on which flywheel you have and how= much wear you have on the clutch slip surface. But on my (I assume well-wo= rn) 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 spacers between the two.

S= o in my mind, a flywheel is the way to go.  Stout, easy to get, pick y= our weight, only mods seem to be drilling the mounting holes and welding on= a second gear ring.
