RE Amemiya Super Greddy 7 RE20B RX-7 FD3S
This RE Amemiya Super Greddy 7 RE20B was built for the annual Tokyo Auto Salon. This exquisite machine is packed with RE Amemiya's tuning knowledge and is setup for the street. The intent of the vehicle is of course, running the Wangan highway. The machine was designed to easily reach high speeds and provide unmatched stability at 300km/h. This makes 300km/h seem like leisurely cruise. The three rotor 20B engine was removed from a Mazda Cosmo. It is fairly easy for RE Amemiya to build a 300km/h engine, and it can be done with a 13B. Then why choose a 20B? The 13B is notoriously known to have a short life span, especially after it has been modified. Also, it lacks the low end torque, and it does not hold the power to leisurely reach, and cruise at 300km/h like the 20B. Therefore, the 20B was chosen, and the low end torque demise was solved. But even though it's a rotary engine, doesn't mean that it is a easy swap. The weight distribution of the well balanced FD becomes thrown off. The 20B had to be offset 10cm to the rear and 6cm to the front in reference to the 13B. Also, the body, subframe, and the propeller shaft all need fabrication. The exterior was dressed up with the RE Amemiya 2006 model Aero kit. It consists of a Porsche 997 front headlights, and the rotary themed rear bumper. The sides consist of super wide fenders to accentuate the whole look. The vehicle was completed just in time for the first ever Pre Tokyo Auto Salon event held in the United States. The vehicle then will be shipped off in time for the real 2006 Tokyo Auto Salon event in Tokyo. ***http://www.Garage411.com/ - Repair guides for your Acura, Honda, BMW, and more!***

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.
