Peripheral Port 12A Rotary Turning Over (Long)

Manually cranking a freshly built 12A peripheral port engine. The engine is built with 3 window bearings, is doweled and has a shimmed oil pressure regulator. Ultimately it will run EFI and be turbocharged. Plugs are installed (listen to those pops!)

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 32: Air Box and Coolant Recovery Tank Fabrication - My 76 Mazda RX-5 Cosmo Restoration
While I'm done with air conditioning, part 32 of my '76 Mazda Cosmo restoration still deals with moving air around, as I fabricate a cold airbox. After working so long on the Vintage Air system I wanted to do some simple fabrication, so the air box was a perfect choice. Made to accept a cone filter it is a true cold airbox that draws air from the inner fender. So not only will the box muffle the sound of the engine but it will also assure the turbo is drawing in the coolest air it can. Since I was in an aluminium fabbing mood after the airbox, I also continue on and build an aluminium coolant recovery bottle. Fitting perfectly in the little space between the radiator support and relay panel, made out of square aluminium tubing, it provides a hidden and elegant solution while not taking up any engine bay space. Included in this episode: making cardboard templates, cutting aluminium, bending/shaping aluminium, loads of TIG welding, nutserts, cutting tubing, fabbing a tank, welding bungs.





Part 33: Turbine Heat Shield Fab & Intake Manifold Cleaning - My 76 Mazda RX-5 Cosmo Restoration
Part 33 of my '76 Mazda Cosmo restoration deals with what I would consider to be two important, though miscellaneous, tasks. While waiting for the Intercooler parts to arrive I tackled what I thought would be a quick and easy job; building a turbine heat shield. I won't admit how long it took but suffice it to say that the Intercooler supplies not only did arrive during the heat shield build, but were also packed away under the car and began to grow shop dust. Regardless of the time it took I must say I'm quite happy with the heat shield as I've seen very few like it. So many of the turbine heat shields on the market are nothing but a bit of bent sheet metal and a mounting bracket. At that point I decided I may as well deal with another small job so I took the time to remove excess OEM equipment from the throttle body and eliminate all the unnecessary vacuum nipples on the upper intake manifold. Included in this episode: turbo turbine heat shield fabrication, turbo assembly/disassembly, template making, stainless steel sheet metal cutting/drilling/grinding/bending, TIG welding stainless, OEM intake manifold extra nipple removal, TIG welding aluminium, FD throttle body simplification

Part 30: Vintage Air Gen II Compac HVAC Install, Part 2 - My 76 Mazda RX-5 Cosmo Restoration
Vintage Air Install Part 1: http://www.youtube.com/watch?v=bK2-A-ou0RM Vintage Air Install Part 3: http://www.youtube.com/watch?v=UN6-kl4Cusg Happy Festivus everyone! Part 30 of my '76 Mazda Cosmo restoration continues the Vintage Air Gen II Compac HVAC installation. In this episode I concentrate primarily on plumbing the system. I know I promised last episode that this half would finish off the install but it has been a lot of work. More than I first anticipated so you'll need to wait until episode 31 for the finishing touches (wiring and ducting). There certainly is a lot of plumbing in an HVAC system, especially when it all has to be figured out from scratch in a custom installation. But the plumbing is one of the most important parts of the install so it makes sense to pay attention to the details. Line placement in an engine bay can make or break the system. I've tried to make use of as many hard lines as possible for both the hot and cold side, which will go a long way in terms of reliability. Included in this episode: measuring and cutting high and low side hoses, installing fittings, installing firewall bulkheads, tricks for hand bending aluminium tube, the cut-and-weld method of tube bending, making brackets, silicone hoes, TIG welding.





Part 31: Vintage Air Gen II Compac HVAC Install, Part 3 - My 76 Mazda RX-5 Cosmo Restoration
Vintage Air Install Part 1: http://www.youtube.com/watch?v=bK2-A-ou0RM Vintage Air Install Part 2: http://www.youtube.com/watch?v=9veZ92j8I8E It's time for the conclusion of the Vintage Air installation on my '76 Mazda Cosmo. Yep, it's episode 31! Part 1 and part 2 covered the mechanical components and plumbing. Part 3 concentrates on wiring up the system, installing the ducting after adapting the stock Cosmo dash vents, and then powering up the system for electrical testing. I also explain a bit about how the MegaSquirt MS3-Pro handles the A/C system. It sure feels good to have it all done and I'm happy with how well I was able to integrate it into the car. Of course the final testing will have to wait until the system is charged and the car is running. Included in this episode: wiring the Vintage Air system, modifying Vintage Air harness to work with EFI/MegaSquirt, WeatherPack connectors, modifying Cosmo dash vents using Vintage Air adapters, cutting/bending/forming aluminium, electrical checks and testing.

Part 3: My 76 RX-5 Cosmo Restoration - Rotary Engine Disassembly And Cleaning
Part 3 of my Cosmo restoration shows disassembly of the 4 port 13B rotary engine and the beginning of the long process of cleaning the internal engine parts. At first I was quite worried about the condition of the engine after looking through the Exhaust ports, but as soon as I opened it up I was pleasantly surprised.

More details and photos of this rebuild can be seen at: http://www.rx8club.com/showthread.php?t=148395 PS: I admit I didn't hold the camera stable enough for the first day of footage. Gave me a damn headache editing the footage.
