Is the dual-turbo Variation in the 13B engine created to electrical power the 3rd-generation RX-7 released in late 1991. Just about every rotor on 13B-REW has just one combustion chamber volume of 654cc. With two rotors, the whole displacement was 1308cc. Excellent match for a Mazda swap or alternative job. https://jdm-mazda-rx-7-fd-13b-rew33108.post-blogs.com/54822454/the-jdm-mazda-rx-7-fd-13b-rew-engine-for-sale-diaries
