In Chile there are only a few Rotaries. Mazda sell a lot of cars
here, but not too many rotaries, and there are no enthusiasts of the wankel
engine, so for support and parts, I’ll have to go to the U.S. anyway.
If I chose and engine, a two rotor, which way do you think is
better, the 2004 renesis for example (I saw one in eBay) or the 89-91 or 93-95
as you said? Can the “modern” renesis be use with a turbo?
Thanks
Gonzalo.

With only a couple of
exceptions the two- and three- rotor engines take the same parts. Only
the "big" center housing and the eccentric shaft are really special
for the 3-rotor engine. Luckily, these don't usually need to be replaced.
Of course, the manifolds, fuel injection and most of the electronics are unique
but you won't use the stock parts anyway. Most everything else is either
the same as, or interchangeable with, the '89-'91 or '93-'95 13B turbo.
Which, of course, brings up the question of whether or not you can get *those*
parts. There is plenty of support in the U.S. for rotary engines, since
Mazda sold lots of RX cars and tuners are used to bringing in Japan-market
parts. Is there such support in Chile? It is tough enough to build
a plane without having to build your own engine too.

Well, actually is not that bad. There are a couple of
runways 3000 ft long,
and others 2000 ft. Altitudes varies from sea level up to 7500 ft, but I
don't plan to go there often, and if I do, the runway is very long. I want
to have a little more power just in case. I think the 200 HP is enough,
right?
Also, what about the parts, it seems that the two rotor parts are much more
available than for the 20B...
Thanks!!

While I am in favor of the rotary, it is worth saying that none of the
very few currently flying turbo rotaries have had trouble free
installations.
I know of John Slade and Dave Leonard, and both have had more than one
turbo failure in the process of finding what works.
I do not know if Mistral is currently selling its turbo version.
What sort of runway length and density altitude are we talking about,
where you intend to operate?
