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.
Part 13: Clearing The Engine Bay - My 76 Mazda RX-5 Cosmo Restoration
With the engine built, it seemed logical to focus a bit on where that
engine is to live: under the hood. Episode 13 has me stripping all the
remaining mechanical components out of the engine bay in preparation for it
to be blasted, repaired and painted. This is dirty grunt work, not
particularly stimulating but at least it isn't sheet metal. It's been a
while since my last update and rest assured, what you see here is only a
small fraction of what has been done. I have plenty more footage ready to
edit. Included in this episode: removing all engine bay mechanical
components, removing brake lines and cylinders, labelling and removing
wiring harnesses, removal of the steering gear, orderly disassembly of an

We have started with a stripped down 1984 Mazda RX7 13BT engine, and will
run through the steps involved in bridge porting the engine, then assembly,
to the start up in its new home, a 1972 Mazda 808 (RX3). [

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
Mazda RX500 test vehicle on a banked circuit and the Mazda Cosmo Sport (or
110S). Originates from the late 60's.
Montaje del Motor Renesis - Mazda RX-8 - NO REBUILD
Proceso de remontaje del motor Renesis de un Mazda RX-8. NO ES UN REBUILD
de Motor puesto que no se han cambiado ninguna junta de estanqueidad,
sellos de aceite o sellos de motor. Se ha limpiado todas las piezas y se
han reutilizado, con el propósito de practicar el montaje del motor y
almacenarlo de una manera mas compacta para en un futuro rehacerlo con
piezas destinadas a su uso en competición.
REPITO: NO REBUILD, el motor no funcionará puesto que no tiene juntas de
estanqueidad, es un video de propósito meramente instructivo.

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 28: Front Inner Fender Reinstall & Using POR-15 - My 76 Mazda RX-5 Cosmo Restoration
Episode 28 of my '76 Mazda RX-5 Cosmo restoration is a sheet metal episode.
Yes, I said sheet metal. In this episode I repair and reinstall a new set
of front inner fender panels (removed all the way back in part 19). I was
able to acquire another set in far better condition and they have been
sitting in the car for several months. While I was waiting for other
unrelated parts to arrive (perhaps a hint for next episode?) I decided to
tackle the inner fenders as it is one of the last major sheet metal repairs
and thus a big milestone in the project. And I was reminded of how much I
don't enjoy sheet metal work. So to make the episode a little more
interesting, I took the opportunity to include some great info on how to
use POR-15. Included in this episode: media blasting, patch panel fab,
welding, grinding, hammer and dolly work, fitting sheet metal panels, spot
welding, using seam sealer, weld primer, prepping for POR-15, using metal
ready, POR-15 tips, applying POR-15.
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
