Part 23: Middle Intake Manifold Fabrication - My 76 Mazda RX-5 Cosmo Restoration

After part 22.5 was posted, it took the remainder of November and December to finish the driver side sheet metal. I worked my butt off to get it done before January 1st, and indeed, accomplished that task so I was able to start the new year sheet metal free! So I am happy to say that episode 23 is sheet metal free! In this episode I fabricate the parts necessary for my unique combination of intake manifolds, combining an FD RX-7 upper intake with an GSL-SE RX-7 lower intake. Doing so requires the fabrication of a custom middle intake manifold out of aluminium, complete with provisions for secondary fuel injectors. You'll see me build flanges from scratch (using my new drill press), measure and cut intake runners, TIG weld it all together, port match the flanges to the gaskets and runners, install injector bungs, curse at the difficult welding I caused, add -6 AN bungs to a stock RX-7 primary fuel rail, and build a fuel rail for the newly fabricated manifold.

I'd like to thank DIYAutoTune ( http://www.diyautotune.com ) for supporting this project and providing some of the parts used in this episode.
