Paul,
The image left-side-p-port.jpg (attached) of Mark Supinsky Mustang
II P-port 13b left side shows P-port with slide throttle as per
rotaryeng.net website and a short exhaust.
The image p-port-turbo.jpg (attached) shows the short exhaust
replaced with a turbo and feeding back into P-port top chamber.
Principally are these the major hardware changes needed to add turbo
to a p-ported engine.

Yes and here are some pictures of the turbo integrated inter-cooler
and p-port intake manifold my welder welded up for Mike Collier's
Long Ez. This will be an easy 300 HP or more. It requires a
butterfly throttle between the turbo and the inter cooler.

The new Borg Warner EFR turbo would be a simplified fit . Divided SS
turbine housing with integrated waste gates. Also boost control and
BOV all in one small package. This one is the 8374... good for about
400 HP take off. Barry Bordes
Barry, where did that Rotary exhaust manifold come from?

Paul,
The flange is from Racing Beat.

"Titanium aluminide has three major intermetallic compounds: gamma
TiAl, alpha 2-Ti_3 Al and TiAl_3 . Among the three, gamma TiAl has
received the most interest and applications. Gamma TiAl has excellent
mechanical properties and oxidation and corrosion resistance at
elevated temperatures (over 600 degrees Celsius), which makes it a
possible replacement for traditional Ni wiki/Nickel based superalloy
components in aircraft turbine engines."
"General Electric has recently announced that gamma TiAl low
pressure turbine blades will be used on its GEnx l_Electric_GEnx
engine, which powers the Boeing 787 aircraft. This is the first
large-scale use of this material on a commercial jet engine. The TiAl
LPT blades are cast by Precision Castparts Corp. and Avio s.p.a.
Machining of the Stage 6, and Stage 7 LPT blades is performed by
Moeller Manufacturing, Aircraft Division, in Wixom, Michigan, USA An
alternate pathway for production of the gamma TiAl blades for the
GEnx and GE9x engines using Additive Manufacturing is also being
explored."
600 C is only 1100 F. These turbo's may not hold up in aircraft use.
The low inertia turbine is of no use to us.
If you use this turbo in a rotary powered aircraft you may be on the
bleeding edge.
=========================================================
jet engine temps
730 C is still only 1340 F still a bit marginal for the rotary with
up to 1800 F in the exhaust. Passenger cars exhaust reach high temps
for just seconds at a time.

There are interesting periodical publications about: Metal Powder
manufacturing', that is an approach that looks highly suitable for producing
prototypes or small series of parts with low cost, that is being
increasingly adopted by the automotive and aircraft industries, perhaps
somebody connected to this excellent site: 'rotaryeng', can provide with
more practical information about the use of Metal Powder manufacturing,
something very close if not identical to 3D printing, in the field of Wankel
Rotary Combustion
Engines. Thanks, best regards. Salud †

What email program are you using? I never saw random indentation
before :)
Please try to left justify. Less editing work for me.
