TWM induction has throttle bodies with two injector pockets each  for
the rotary.  48/50/55 mm available.  They did not have a photo but
something like this off the shelf needs checking out.  I gather it is
a new product.      Jerry

I don't see any Mazda rotaries in there. I see Miata. What they
do show is too short for our purpose.

Go to the 2900 series throttle bodies.  These are the direct
replacements for the old Weber DCOE.  On top of that page is a link
to an article for carbs vs, injection.  It seems to be a good dyno
article for tuning a 13B.  It also shows a good picture of the two
piece manifold with the 2900 bolted up.

Mike,  check out the 3000 series. These are new throttle bodies with
two injector pockets specifically for the rotary according to the
text.  No pics but we can contact TWM.   Jerry
