This FD also comes as a sticker04Rotary Heart
Two rotors.
Zero pistons.
The 13B-REW has no valves and no connecting rods: each rotor spins eccentrically inside an epitrochoid housing, handling intake, compression, combustion and exhaust in a single turn. From the factory it ran sequential twin turbos; this FD came from Japan already converted to a single HKS GT3-4R turbo run by an HKS F-CON V-Pro.
To-scale cutaway · R 105 mm · e 15 mm · the rotor turns at 1/3 shaft speed

Filling up at the gas station, a convoy with a Civic, a whole day of winter sun and another FD parked a few meters away. The first time the FD went out to show itself off.

The 13B-REW in a nutshell
Two rotors, zero pistons and a scary reputation. What makes the FD's engine special, what it needs to stay healthy and where the brap brap comes from.
08Meet Hiro
Rotary heart.
Shiba soul.
HIROTARY is Hiro + rotary. Hiro is the family Shiba Inu and official co-pilot: not a mascot bolted onto the project, but half of its name. And yes: Hiroshima, home of Mazda, starts with Hiro too.
