Is the twin-turbo Variation with the 13B engine built to power the 3rd-generation RX-seven launched in late 1991. Just about every rotor on 13B-REW has just one combustion chamber quantity of 654cc. With two rotors, the entire displacement was 1308cc. Fantastic in shape for a Mazda swap or alternative venture. https://mazda-rx-7-engine68912.blog2freedom.com/39003533/a-secret-weapon-for-mazda-13b-motor-for-sale
