Neat Jalopnik article with some of the best pictures I have found of the 4 rotor engine. Also a good explainer on intake runner length vs rpm, I think it gives some nice background on how Mazda got to the RX8 intake system.
here's bit of trivia maybe not covered in the article. you see those pulleys on the carbon fiber plate that actually change the runner length by pulling on the cables? those pulleys are moved by windshield wiper motors
