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.

Also something to note around Mighty Car Mods: we are normal guys and are
not trained mechanics. We like to make interesting car mods and show you
how we've gone about it, but we can't promise that anything we show you
will work for your particular car, or that you won't harm yourself, someone
else, your car or your warranty doing it. Please be safe, be responsible
and unless you know what you're doing, do not fool around with very serious
machinery just because you've seen us make it look so easy. Talk to a
qualified mechanic if you are in any doubt.
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.

Part 10: My 76 Mazda RX-5 Cosmo Restoration - Shaved Door Sheet Metal
In part 10 of my 1976 Mazda Cosmo restoration, I continue the surprisingly
long task of shaving the door handles. Last episode I left off after
cutting the patch panel to fill the hole in the passenger door. This time I
weld the panel in, fix the huge amount of warpage my improper welding
technique caused, then do the same on the passenger side. Shaving the door
handles took a lot more time than I thought it would and it feels nice to
have it all finally done. Included in this episode: patching door handle
holes, welding sheet metal, grinding down welds, hammering out warp caused
by welding, learning how to not screw it up next time.
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.
Part 35: Water To Air Intercooler Installation, Part 2 - My 76 Mazda RX-5 Cosmo Restoration
In the last episode of my '76 Mazda Cosmo restoration, the basic components
of the water to air Intercooler system were laid out along
with the considerable amount of fabrication needed to build the throttle
body inlet, Intercooler
piping and water tank. As well as mount the heat exchanger and BOV. In part
35, we finish up the water to air Intercooler installation by taking care
of mounting the pump, plumbing all the water lines and wiring up the
system. Additionally support brackets are built to support the piping. Lack
of space meant I had to get creative with pump position after accidentally
creating a clearance issue with the water fittings. However once mounted I
was very happy with pump position and the plumbing was straightforward.
Included in this episode: Cutting/grinding/drilling aluminium, making
aluminium brackets, assembling AN house and fittings, wiring relay to spare
Megasquirt output, adding temperature sensor to Megasquirt analog input,
plumbing air to water Intercooler with tank and pump, TIG
MAZDA RX7 Rotary Engine Failures
MAZDA RX7 Rotary Engine Failures
MAZDA RX7 rotary engines are strong and displace a lot of power for their
size. Traditionally, carbon deposits and heat are their biggest enemies.
Rotary engines run with a huge temperature differential, meaning that one
side of the engine runs cooler that the combustion side (side with the park
plugs). As a rule, cooling system damage should be avoided at all costs.
Learn how these issues affect rotary engines and what kind of damage is
done to them when they really fail.
