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

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

       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.

I have similar questions (as another old fart) What kind of sane low
power (without turbo) Mazda engine
would be usable in piper 140 0r cessna 150 or possibly a zenith zodiak xl
kit plane????????????? As a
life long mechanic on imported cars and restoring old ones part time the
rotary has always facinated me
for some sort of air craft use.As a former racer I can sympathize with
others need for more and MORE
SPEED.However that is no longer my priority!!!!!!!!

If it is certified airplane the FAA will not let you get away with it.
I am not sure the allowable engine weight of a Zenith Zodiak. If it will 
take an O-320 it will take a rotary. Almost any Mazda rotary will work.
