Is definitely the twin-turbo Model in the 13B engine designed to ability the third-technology RX-7 released in late 1991. Just about every rotor on 13B-REW has only one combustion chamber volume of 654cc. With two rotors, the total displacement was 1308cc. Great suit for a Mazda swap or alternative venture. https://13brotarymotorforsale80191.therainblog.com/37567568/details-fiction-and-mazda-13b-rew-motor-for-sale
