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.
