Is the dual-turbo Edition of the 13B engine meant to ability the third-era RX-seven launched in late 1991. Each individual rotor on 13B-REW has a single combustion chamber volume of 654cc. With two rotors, the total displacement was 1308cc. Fantastic in shape for any Mazda swap or replacement challenge.
