Is the dual-turbo version with the 13B engine created to energy the 3rd-generation RX-seven released in late 1991. Every single rotor on 13B-REW has just one combustion chamber volume of 654cc. With two rotors, the full displacement was 1308cc. Excellent in good shape for any Mazda swap or substitution venture. https://jdm-mazda-rx-7-fd-13b-rew74173.bloginder.com/34527290/about-jdm-mazda-rx-7-fd-13b-rew-engine-for-sale
