Part 38: Fuel Tank Restoration With POR-15 Sealing Kit - My 76 Mazda RX-5 Cosmo Restoration
I guarantee that aside from part 38 of my '76 Cosmo Restoration, you will not find more footage on YouTube of someone shaking a fuel tank. You have my word that this is the most tank shaking coverage you will see in any video. Why so much tank agitation? Because in this episode I clean and seal the 40 year old fuel tank using the POR-15 fuel tank restoration kit. This is something which several have requested be shown so I figured as sealing was a common issue for old fuel tanks, why not dedicate an episode to the task. I begin by recycling some of the cleaning footage from the past two episodes then move right into the process of the POR-15 kit. First any remaining debris is "chained out" by using the old trick of rattling some chains around inside the tank. Then the tank is cleaned with the supplied cleaner, etched with MetalPrep and finally coated with the sealer. The end result is a tank looking better inside than the day it came the assembly line which will not be subject to future corrosion. To go with the spiffy clean interior, the outside is given a coat of POR-15 rust preventative paint as well. And did I mention this is my first episode in HD?!





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 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 27: Cooling System - My 76 Mazda RX-5 Cosmo Restoration
In part 27 of my '76 Mazda RX-5 Cosmo restoration, I focus on the cooling system. It seemed an appropriate thing to do with the hot summer weather. The stock Cosmo rad was leaking, small and hard to obtain so I installed a universal aluminum radiator after modifying it to fit. With the new rad, the oil cooler had to be relocated, the engine water inlets/outlets modified, and a number of other changes had to be made. Once all that was done, it was time to install the dual cooling fans. Now that the cooling system is new, modern and overbuilt, I should have no problems even under the worst conditions. Included in this episode: modifying a universal rad to fit, TIG welding brackets, making oil cooler brackets, MIG welding them in place, modifying thermostat and water pump housing, mounting the oil cooler, trimming and modifying an electric fan shroud to fit the rad, welding mounting fan mounting brackets, wiring up the e-fans, testing the fans.

Rotary 20B turbo RX7 - Dyno & track
Built as an all-round event's car, Charles' Mazda RX-7 has undergone serious chassis and engine changes including a Promaz Automotive bridge-port 20B rotary engine. Boost comes from a Garrett turbocharger while the engine runs on methanol fuel controlled by a MicroTech LT16 computer and LTC dash logger. Backed by a Jerico 5-speed dogbox, the clutch was suffering on the Dyno as the Promaz team got the car ready for Performance Car Mania.

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.
