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.

What its like owning a 3 Rotor 20B RX-7
I have one of the most amazing custom RX-7s in the world. I want to share
my experience of owning and driving such a unique car.
I explain where the engine came from, why its so special, and what it does
to a Mazda RX-7
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

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.
TCM's New Diesel Project
TCM said more than a year ago that it wanted to get an aerodiesel into its
product line and now it has one. The company bought diesel technology
already developed from a European source and is forging ahead with its own
Mazda Rx7 4-rotor race car. The making of a Defined Autoworks Beast. [Offical Video]
Never before seen footage showing the assembly/start-up of our custom
4-rotor. It is the first 4-rotor since the 787b to use triple spark plugs
per rotor. It is also the first since the 787 to feature telescoping intake
manifold. Custom made slide throttle body system. A world first however is
the use of a center main bearing and 4-piece eccentric shaft. Quick specs-
9.7:1 rotors, lightened and race clearanced. Race main bearings, and race
rotor bearings, ceramic NRS 2mm apex seals. Custom stationary gears, Full
custom Peripheral Port in each rotor housing (defined auto), Aluminum side
housings for reduced weight. Needle roller bearing in the center housing.

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 ].
20B PP Mazda RX8 great sound!
Panspeed Racing of Japan easily had the loudest car at World Time Attack
Challenge with Naoki Hattori behind the wheel. The naturally aspirated 20B
peripheral ported rotary powered yet subtle looking Mazda RX8 was competing
in the Pro Class and ran a best time of 1:35.57 for the event.
