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 36: Fuel System and Fuel Lines - My 76 Mazda RX-5 Cosmo Restoration
With any rotary, a robust fuel system is a critical component in reliability. This is what will be covered in part 36 of my '76 Mazda Cosmo restoration. In this episode I set up the engine bay section of the fuel system. This includes the regulator, fuel Y block, and all the fuel hoses using braided line and AN fittings. I also bend up a set of stainless fuel lines for underneath the car. The fuel tank also needed some attention so I begin the process of getting it cleaned out and ready for modification to handle an in-tank EFI pump.





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 34: Water To Air Intercooler Installation, Part 1 - My 76 Mazda RX-5 Cosmo Restoration
It's time for part 34 of my '76 Mazda RX-5 Cosmo restoration. This time, I'm installing the water to air Intercooler. I've installed and fabricated plenty of air to air Intercoolers in my time but never a water to air unit. I chose to use water to air on the Cosmo because it meant that I could keep the piping as short as possible for the best Boost response and because of the limited amount of room to run charge piping out to the front of the car due to the large rad and A/C condenser. It was definitely a learning experience for me as I underestimated the amount of time needed to fabricate all of the components. Thus, I have split the episode into two parts. In part 1 of the installation, I fabricate a throttle inlet adapter to fit the FD throttle body, position and mount the Intercooler, build charge piping, weld on a BOV flange and IAT bung, fabricate an aluminium water tank with inlet/outlet/fill bungs and mount the heat front heat exchanger.





Mazda RX-7 Spitting Huge Flames from Exhaust!
When I was driving back from an event, this turbocharged Mazda RX-7 FD3S passed me in a tunnel. As you can see this tuned Mazda RX-7 FD3S was spitting some huge flames from the Exhaust! Hate it or love it, I really enjoyed it! :) Follow me: http://www.Gumbal.tv 1st Channel: http://www.YouTube.com/GUMBAL 2nd Channel: http://www.YouTube.com/GUMBALTV 3rd Channel: http://www.YouTube.com/CarChannelClassic FACEBOOK: http://www.fb.com/GUMBALTV INSTAGRAM: http://www.instagram.com/GUMBALTV TWITTER: http://Twitter.com/GUMBALTV GOOGLE+: https://plus.google.com/+Gumbal Thanks you for watching my videos.

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.





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 welding brackets.

20B rotary RX-7 Spirit R: The Ultimate Street Mazda
Built by Promaz Automotive, we think it's hard to go past Steve's wicked Series 8 FD RX-7 if rotaries are your game. Limited to around 1500 unit's, the Spirit R was the last of the RX-7's and featured a lot of upgraded factory parts as well as a low 1100kg weight. Now powered by a lethal Promaz triple rotor 20B extend port rotary engine, power is aided by a Garrett GT42R turbo and MicroTech fuel system and transmitted through an Albins 5-speed gearbox and KAAZ rear end [ http://www.promaz.com.au ]. http://www.facebook.com/fullBoostcomau http://www.youtube.com/user/fullBoostcomau http://www.fullBoost.com.au
