The 13B rotary is mounted in the car. To preserve weight distribution, it was placed as far back toward the firewall as possible. That meant modifying the body-side mounts to lower the engine and make room for the transmission—a substantial undertaking. The builder originally wanted a huge K3 turbo. Making it work required misfiring ignition, and controlling that required Motec. The project therefore began with the turbo and ultimately grew to include Motec engine management. The target is 600 hp at 1.7 kg/cm² of boost, which should make it faster than an FC3S.
