Hello Paul,
I hope you will allow me to list my 20B engine for sale on your bulletin board!!
I've been active on the rotary aircraft engine lists for several years.
I have a Standard Velocity Fixed Gear (~75% complete airframe) and a "real" complete 20B engine
(turbos, intake, exhaust manifold, alt., air pump, pulleys, wiring harness, oil pan, ECU, and
everything else......complete) that I had imported from New Zealand and was converting for the
plane.
I am now (regretfully) forced to sell both my Velocity Kit and 20B engine due to Divorce. This
engine has been completely rebuilt with all new seals, O-rings, gaskets, oil pump and chain, 2 new
rotors, 2 new rotor housings, new pulleys / belts, etc.....The 20B engine has already been
completely rebuilt, using Bruce Turrentine's Video, to include two new rotors and rotor housings,
all seals, apex seals, etc. I did the tear down and rebuild myself. I was a mechanic for 12
years before returning to college to finish my degree, so I do have plenty of practical mechanical
experience. I did a thorough and detailed rebuild, checking all tolerances and clearances along
the way. Two of the rotors and rotor housing were replaced only because I negotiated to have them
included in the engine purchase and shipped with the engine. I followed the guidance in Bruce's
video as well as over 18 months of detailed cleaning, measuring, consulting with various member of
this and other Mazda rotary engine groups. The engine is VERY close to being able to do the first
start up, but I have not yet built an exhaust system. I can provide a long list of new parts
that were replaced during the rebuild. All housings that were not replaced measured well within
tolerance. This also includes Tracy's new RD1-B 6 pinion redrive which I have slightly modified
the plate to allow for motor mount clearance and relocation of the starter. It also includes
Tracy's EC2 EFI / EI Controller with updates. I have already installed and setup the redrive and
completed the wiring harness for the EC2 into my Velocity. This wiring harness may or may not be
of use to you in your specific installation, but it will only require a new $2 connector to start
your own harness. I have completed wiring the fuel injectors and have already purchased the GM
coils and special connectors and wired them.
In addition, I've installed the new metering pump used to inject 2-cycle oil. I've lightened the
original intake manifold for either permanent or temporary use at your descretion. I planned to
start and run the engine with the original intake manifold and then experiment from there based on
weight and space requirements. It comes with the original dual sequential turbos (although not
much use to us probably), original ECU (could be sold on e-bay), original wiring harness /
connectors, GM coils and connectors, injectors, and much more.
Also included is a very nice motor mount for this 20B engine that was originally built for Charles
Harbert by modifying a Franklin mount. It was A&P welded, heat treated, and X-rayed for cracks.
When he sold his 20B engine, I bought the motor mount from him.
I can provide pics via e-mail and more detailed information to anyone who is seriously interested.
You're also welcome to call anytime: 214-335-0095 Cell
Will sell with or without the motor mount.
Price:
$12,500 w/ motor mount - you pay shipping
$11,500 w/o motor mount - you pay shipping
Interested parties, please contact me with any reasonable offer.
Thanks,
