Will be the twin-turbo Variation on the 13B engine created to power the third-era RX-7 introduced in late 1991. Each and every rotor on 13B-REW has a single combustion chamber quantity of 654cc. With two rotors, the total displacement was 1308cc. Great suit for a Mazda swap or alternative job. https://rx7-engine02852.collectblogs.com/83488300/the-mazda-rotary-engine-sale-diaries
