Part 24: MegaSquirt MS3-Pro Installation - My 76 Mazda RX-5 Cosmo Restoration

Part 24 of my '76 Cosmo restoration is here! And I'm going to come right out and warn you; this is a long one. There is a lot of detail here, for you see, this episode covers in it's entirety the installation of the MegaSquirt MS3-Pro EFI system. Like the engine build in part 12, I decided to cover the entire process in a way that would help anyone performing a similar installation. And while this specifically covers the MS3-Pro, all the information is valid for any MegaSquirt installation and indeed, any other brand of standalone as well. In this episode you'll see from scratch the MS3-Pro installation from bare engine bay to fully wired and functional EFI system. Included is detailed coverage of making an ECU mounting panel, wiring in all the injectors and sensors, wiring up the 2nd gen RX-7 CAS and coils, Boost solenoid, e-fan relays and other EFI related accessories. So pour yourself a big drink, get comfortable, and enjoy. A huge thanks goes out to DIYAutoTune ( http://www.diyautotune.com ) for providing the MS3-Pro and other parts used in this installation.

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 22.5: Updates, Q and A, Misc - My 76 Mazda RX-5 Cosmo Restoration
June, July, August, September, October and November; Hey, I wasn't kidding when I said in episode 22 that it would be a bit of a wait for the next one! In that time I've been as hard at work on the Cosmo as I could manage, which unfortunately is not as much as I would have liked. It's been a busy summer with plenty taking me out of the shop. Even still, I've been working as much as I can and have picked up the pace over the last two months to the point where the driver side sheet metal is almost done. So what's in this episode, strangely titled as "Part 22.5"? Well, with the help of my special guest Rose Cora Perry, I answer some of the most common questions about the project. And along the way, there are a few tips and tricks thrown in, as well as a little bit of why the driver side repairs have taken so long. This episode is a little different, so I hope you enjoy...





Part 18: Floor, Frame, Firewall - My 76 Mazda RX-5 Cosmo Restoration
It's time finally for part 18 of my Mazda RX-5 Cosmo restoration. In episode 19 I continue repairing the rear floor pan, this time dealing with the drivers rear seat area as well as some of the bulkhead and frame below it. Once tired of messing about with floor pans, I move onto some easy sheet metal work involving filling some of the unnecessary holes in the firewall. Included in this episode: cutting out rusty sheet metal, cleaning up rust, prepping the areas for repair, fabricating patch panels, hand forming patch panels, welding in new metal patch panels, smoothing a firewall, fixing sheet metal weld distortion, a tornado.





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 39: Front Suspension & Rack and Pinion Conversion, Part 1 - My 76 Mazda RX-5 Cosmo Restoration
I know it's been a while and since the front suspension work is still ongoing, I've decided to split it up into two episodes. So for part 39 of my '76 Mazda Cosmo restoration, I begin the work of updating the front suspension and converting the car from recirculating ball steering to rack and pinion. While my original goal was to mount the entire FC RX-7 front subframe, it became obvious very early that was not feasible. Instead I began combining parts of the RX-7 suspension with the Cosmo suspension to create a unique solution. Once the basics were laid out, conversion to rack and pinion steering began utilizing a NA Miata steering rack. And then I hit a silly, obvious snag...





Part 22: Front Sheet Metal Extravaganza 2 - My 76 Mazda RX-5 Cosmo Restoration
Part 22 of my '76 Mazda RX-7 Cosmo restoration finishes up the passenger side front sheet metal. In this episode I reconstruct the passenger front inner and outer sill, floor and kick panel. And the great thing is that as promised, this is the last sheet metal episode for a long, long time! While I have the same set of repairs to do on the driver side, that will all be done off camera so that the next episode gets to the good stuff. Included in this episode: making templates, fabricating patch panels, POR-15, cutting, grinding, welding, floor pan repair.

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 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.
