Onboard 1991 Mazda RX7 IMSA GTO four-rotor at Rolex Monterey Motorsports Reunion
What's it like to drive a priceless, four-rotored piece of Mazda history on the weekends? Ask Jeremy Barnes, the transplanted Aussie who heads Mazda North America's public relations department, and the amateur racer can't help but let an ear-to-ear grin begin to rise. Along with a dozen other Mazda colleagues, Barnes spent last weekend at the aptly-names Mazda Raceway Laguna Seca for the Rolex Monterey Motorsports Reunion where five of the brand's four-rotor rockets were on display. Thankfully, the static display in the paddock came to life twice a day as the cars were raced in the IMSA group where Barnes is entrusted to wring the neck of the tubeframe 1991 RX7 IMSA GTO, and as he shares below and in the video, each session in the flame-spitting beast is filled with sensory overload.

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.
