Part 25: Turbo Manifold Fabrication - My 76 Mazda RX-5 Cosmo Restoration
Episode 25 of my '76 Mazda RX-5 Cosmo restoration is another long one, covering in its entirety the fabrication of the turbocharger manifold. Suddenly the engine bay started to look a little cramped when I began to position the GT3076R, so it took some plumbing to build the required manifold. Constructed out of 1.5" SCH40 304 stainless steel pipe, it was fully TIG welded with an argon back purge. Yes, this is another long episode because I wanted to show the manifold fabrication process in glorious detail so that this video would be a useful resource for anyone wanting to build a custom turbo manifold. So as I say, grab your favourite adult beverage, sit back, and enjoy. Included in this episode: fabricating a 13B Exhaust flange, fabbing a merge collector, positioning a turbo in the engine bay, measuring, cutting and fitting stainless pipe and els, tacking in position, setting up a back purge, final welding, port matching, custom heat shields. A huge thank you to ATP turbo ( http://www.atpturbo.com ) for helping out with some of the parts used in this episode.





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 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.
