I bought this engine with 44,000 miles from a large salvage dearler in
Texas.  Up till this time I had never seen, heard or touched one.  Most of
my internet research has been on pre-2004 engines.  Not alot of info on the
Renesis engine that I can find.

I want to convert this 2006 auto engine over for aircraft use.  What is the
best mounting system ?  I'm looking at a Van's RV aircraft for mounting.

What sensors can I save and use ?  Most of the wires have been cut.  The
intake system is still on the engine.  No exhaust.

Are there any manuals available besides Mazda ?  They want $150 for
their's.  That's too much for me.

Thanks for any help.  I'm sure to have more questions later.  Just want to
get it running.

Jim, first thing is read the web site below.
http://www.rotaryeng.net

You can get the RX8 manuals from this site.
http://foxed.ca/foxed/index.php?page=rx7manual

Save all the sensors.

Also search youtube for my name with a 2.
In other words "PaulLamar2"

We have some motor mounts for all RV's so we will need to know
which RV you are interested in. The two rotor is good for just
about any except perhaps the RV10. That would work best with a 3 rotor.

Jim in Idaho,  Another site you might check out is the  "real world
solutions inc"  at www.rotaryaviation.com  where you can get the Bruce
Turrentine vidio  showing a rotary engine dissassembly and inspection.
Grocer store oven cleaner will clean the metal parts, just separate the
rubber seals first. I just spray the parts and put in a zip loc bag for a
day.You will need a propeler speed reduction unit (PSRU) and engine control
unit for the fuel injection and ignition. Rotaryaviation.com  is their site
and they are the standard for these products with flight proven reliability

. Their PSRU is used on most flying airplanes as well as those under
construction.  The front mount plate shown in the above images  from Jeff
Doodrige mounts close to the center of gravity of the engine/PSRU and
counters the 600 ft lbs of prop torque without transmitting it through the
engine block. Paul Lamar sells a book on cooling rotary engines in aircraft
which is the most critical part of the installation.

        The stock intake manifold doesn't clear the cowl on top of the
engine and is replaced by a tuned length tubular (18") intake manifold and
plenum.Converting your rotor housings to P-port reduces the intake runners
to only two, reduces weight and complexity, and adds considerable
horsepower.  For the exhaust don't use mild steel. A rotary is hotter and
supersonic at the port. Only stainless (321 with .065 wall thickness) is
recommended. A muffler as well as all the P-port conversion hardware is
available thru this site.

     The idea of an engine turning 6000 RPM takes getting used to, however
only the E-shaft turns this speed, everything else is 2000 RPM. At these
rotational sppeds the gas pressure and centrifical force are balanced and it
is actually easier on the engine.

That is a good over view George. Can I use some or all on the web site?
I make the mistake of taking that for granted sometimes.
