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
A huge thank you to ATP turbo (

Turbo Peripheral Port Start-up and Idle
To the Youtube 'tards: This was a quick first start up video before
everything was assembled. The intake plenum, tubing, and coolant lines were
installed after the bugs were worked out.
