Todd,
   The "Mistral" engine is not based on the Renesis but on the 89-91
13B to my knowledge........They now produce all parts (paper trail)
for the certified version of their engines so have been able to build
parts with out any of the compromises made by using stock Mazda
parts in their early experimental engines.......Therefore the new
production backplates wll not adapt to the stock Mazda 13B and
all early backplates were used on engines sold and a few were sold
to experimenters........I have never asked "Mistral" how many were
sold to guys like me..........FWIW --

Since the original is of no use to them, maybe they'd put the molds 'in the public domain'. :-)

Seriously, if they'd just release the CAD files used to make the parts for the castings, there are people who could (& probably would) do the casting & machining for a lot less money than the large scale production houses would charge.

Then there's Ken Powell's technique of welding up the ears in 4130, made to bolt on to the side of the engine instead of the accessory case.
