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.

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.

MAZDA RX7 Rotary Engine, How It Works
MAZDA RX7 Rotary Engine, How It Works
The MAZDA RX7 rotary or Wankel engine is a marvel of engineering. It has
won more races than any other vehicle in its class. Rotary engines develop
a great deal of power for their weight (power to weight ratio). They're
also able to develop high RPM bursts like no other internal combustion
engine. Learn the details of it operation, how the rotor transfers power to
the output shaft, what it the stationary gear set, what is the rotor to
output shaft ration and relationship. Get all the specifics on the rotary
engine's operation here in this video.
Presented using advanced software CG animation technology to help you
understand. Part of our Automotive Technology Rotary Wankel engines and
MAZDA RX7-RX8 series shown here on this channel. Enjoy...

Este coche de carreras se convirtió en leyenda gracias al boicot de las
grandes Marcas atraves de la FIA que prohibió el uso de cualquier tipo de
motor Wankel (rotativo) alegando un peso inferior al resto de motores y una
equivalencia de cilindrada no equiparable.
