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 engine bay.
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 11: Power Windows Installation - My 76 Mazda RX-5 Cosmo Restoration
I now present episode 11 of my '76 Mazda RX-5 Cosmo restoration. This episode deals with the task of installing the AutoLoc PW4650 universal power window kit. This kit includes motorized actuators which rotate the existing manual window cranks, driving the manual regulator and thus converting it to power without the need to fit an entirely new window regulator. Additionally it includes all wiring and switches (not installed yet), and mounting brackets. As it is a universal kit, it is universally wrong for every application and must be customized to fit. The installation was straightforward though time consuming. I have to admit, this episode is a monstrosity and quite a bit longer than normal. But for good reason, because I didn't want to do a "To be continued" as the next episode will be quite special. Included in this part: custom fitting AutoLoc universal power window actuators, making cutting channels into the inner door for space, patching and finishing off the channels with welding and sheet metal, cutting sheet metal from templates, media blasting before painting, making brackets for actuators, a surprise at the end.

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...

Part 23: Middle Intake Manifold Fabrication - My 76 Mazda RX-5 Cosmo Restoration
After part 22.5 was posted, it took the remainder of November and December to finish the driver side sheet metal. I worked my butt off to get it done before January 1st, and indeed, accomplished that task so I was able to start the new year sheet metal free! So I am happy to say that episode 23 is sheet metal free! In this episode I fabricate the parts necessary for my unique combination of intake manifolds, combining an FD RX-7 upper intake with an GSL-SE RX-7 lower intake. Doing so requires the fabrication of a custom middle intake manifold out of aluminium, complete with provisions for secondary fuel injectors. You'll see me build flanges from scratch (using my new drill press), measure and cut intake runners, TIG weld it all together, port match the flanges to the gaskets and runners, install injector bungs, curse at the difficult welding I caused, add -6 AN bungs to a stock RX-7 primary fuel rail, and build a fuel rail for the newly fabricated manifold.
I'd like to thank DIYAutoTune ( http://www.diyautotune.com ) for supporting this project and providing some of the parts used in this episode.
