Hi Paul, I just came from the junk yard. They have 2 '87  13B engines.
One is out of the car with no coils and they are asking $600. The other
one is in the car with 110,000 miles and I can have it for $300 with the
coils. Do I need anything else off the car. Both engines are NA. What do
you think? Should I look for newer model? I know that the coils alone
are $300.

BTW I will keep your engine mount drawing for when I am ready to build
one.

I am not sure about the coils being $300. I would not think so.
It is the little two inch square black ignition modules mounted
on the side of the distributors that are $300 each, $600 total. 

Now as far as the coils go I would not take a chance on them in an
airplane but I'll bet Tracy has :-) I would buy some racing coils
or better yet some with built in transistors designed to fire only one
spark
plug. That way if one fails you still have three spark plugs working.

110,000 miles is not much for a Mazda Rotary engine. Can you take
a charged battery in and a compression checker? If the engine will turn
over
you can check the compression. BTW I think you will need the starter
at least. Sounds like the one in the car is the one to go for.
You can buy a lot of new seals and O-rings  for $300.
