Mazda RX-7 13B-REW Rotary Engine Build: Part 1
Engine Teardown

Thanks to the generous support of the original motor oil company, Valvoline, we’ve begun a 4-part video series documenting how to disassemble and rebuild the engine out of our JDM 1993 Mazda RX-7. This two-rotor sequentially turbocharged Wankel engine is a masterpiece of Japanese engineering and surely one of the most unique engine designs of all-time.

We are huge rotary engine fans, as evidenced by this ‘How Rotary Engines Works‘ story we posted 5 years ago, shortly after we started Speed Academy. So we’re very excited to be building our own 13B-REW rotary engine with our long-time friend and rotary engine builder Joe Ferguson from RPM Motorsports.

As you’ll see below, in Part 1 of this video series we start the process by fully disassembling the engine and discover some not-so-good surprises along the way. Stay tuned for Part 2 next week, where we’ll show you our rebuild plan and get to work on clearancing the side seals and apex seals.
