Is the twin-turbo Variation from the 13B engine meant to electric power the 3rd-era RX-7 launched in late 1991. Each rotor on 13B-REW has a single combustion chamber volume of 654cc. With two rotors, the whole displacement was 1308cc. Fantastic in good shape for any Mazda swap or substitute project. https://mazda-rx-7-engine05825.blogzag.com/75029932/examine-this-report-on-13b-engine-for-sale
