My un-learned opinion which might not mean much because I'm a single rotor

to cruise around like we used to at minimum cost and complexity.

Question
If you needed to buy an engine TODAY to put in your aircraft, and you had
decided on a rotary, would you...

1) Pull an engine out of a RX7/junkyard and
       a) rebuild it with appropriate aircraft modifications, but basically stock
       b) rebuild it with Peripheral Ports

I bought a '8713B out of a junker and from an educational standpoint
alone it
was worth every penny. I am rebuilding it as a single rotor P-Port
testbed engine
to test some ideas I would like to try out. P-Port because it seems to
be the
simplest way to get the most for the least out of the Mazda engine.
Probably
will never fly the major parts because too many are close to or out of spec.

2) OR Spend more money and
       a) buy a Renisis, and get it ready for aircraft use

Don't see much advantage for me. Choice b) below would be much more suitable
(assuming that the 3-+ pounds is a typo). The cost of the RB housings
has to be
weighed against the cost of an equivalent Rotax, the ease of
maintenance, and
the potential for vastly better reliability.

       b) by the racing beat housings, for about the same price as a new Renisis,
and build an aircraft motor (added cost).  Please note this would mean
getting Peripheral Ports and saving 3-+ pounds.

Finally how would a turbo factor into your choice. ---- Not at all
