Mazda 20B (3 Rotor) Rotary aircraft engine, second run.
This engine was built with Racing Beat aluminum panels, hand cast aluminum Intake manifold. Custom dual servo fly by wire throttle body. Carbon fiber plenum and runners.
It uses 550CC Ford Racing injectors, Real world ECU and prop drive. Inconel headers, Spin Tech muffler, and 2.5 years of work !
The dry sump configuration allowed for custom mounts that mate up to a dynafocal mount designed for an IO-540 engine.
This engine is estimated at 330HP and the net weight change to the aircraft is expected to be 250 to 300 lbs lighter but still with 10% more horsepower.
Part 12: 13B Rotary Engine Rebuild - My 76 Mazda RX-5 Cosmo Restoration
Just as I promised last episode, it is finally time to build the engine!
Part 12 of my RX-5 Cosmo restoration covers the entire process of building
the 6 port 13B Mazda rotary engine. While this engine is a hybrid of GSL-SE
RX-7 and Cosmo parts, the process is the same for any rotary from a 12A to
a 13B NA, 13B turbo, 13B-REW or any
other variant of the 13B. This video shows the whole process of the engine
build, starting from measuring the rotors and covering everything else
including clearancing the side seals, assembling the rotors, complete
assembly the short block, setting the eccentric shaft end play and
installing the front cover and everything underneath it. It's probably the
most complete engine build video outside of what you can buy from the
vendors, and as such, is an hour long. After this one, I'm going back to
videos under 20 minutes. But for now, grab a beverage of your choice, sit
back, and enjoy.
Rotary Engine Breakthrough?
The Wankel engine always held out a lot of promise, but never was able to
fully deliver on those promises. It was never very fuel efficient, and the
Exhaust temperatures were very high.
But now an independent car tech thinks he has stumbled onto what held that

The Mazda Rotary Engine Part 1
Educational film by Toyo Kogyo about the Mazda Rotary Engine. Shows how the
Rotary engine works with comparisons to the Piston Engine. Also shows the

110S). Originates from the late 60's.
20B rotary RX-7 Spirit R: The Ultimate Street Mazda
Built by Promaz Automotive, we think it's hard to go past Steve's wicked
Series 8 FD RX-7 if rotaries are your game. Limited to around 1500 unit's,
the Spirit R was the last of the RX-7's and featured a lot of upgraded
factory parts as well as a low 1100kg weight.
Now powered by a lethal Promaz triple rotor 20B extend port rotary engine,
power is aided by a Garrett GT42R turbo
and MicroTech fuel system and transmitted through an Albins 5-speed gearbox
and KAAZ rear end [ http://www.promaz.com.au ].
