1300hp Mazda 13B | PRO-RX8 rotary by Promaz

An evolution over the last couple of years, the Promaz Racing Mazda RX-8 recently ran a personal best pass at the Brisbane Jamboree of @ 188mph. Taking a closer look under the skin, the RX-8 is powered by a Promaz 13B Cosmo bridge port race engine that features BilletPro front and rear billet end plates for added strength and durability. A unique feature of these plates is the innovative locking mechanism of the removable cast iron insert. There are many other custom CNC machined parts on this car including the intake plenum and sump just to name a few.
