     Paul the 93-95 RX-7 & Jap Cosmo have the same basic bolt pattern as the
 86-91 engines. the difference is one less bolt on plug side where 13BREW and
 Cosmo starter mounts and two additional bolts at top of rear housing. there
is no reason a 86-91 flywheel and starter cannot be used IMHO. Eliminating the
 need for the expensive and hard to find 13BREW/Cosmo flywheel & starter.

Do you have a drawing of the 93 up/Cosmo  end house bolt pattern?

      Paul,
       I don't have a drawing as yet. I will try to make  one this weekend
 and send it to you. I lack CAD skills so will leave that to you. Other than
 the two extra holes at top of rear housing and one less on plug side as I said
 the bolt pattern is same as 86-91(actually 74-91). End user could add the extra
 top holes very easily and not use the extra hole on plug side if starter is
 left on exhaust side.
