EFS-2 TBI to the compressor inlet. The stock wastegate controller was removed, and a mechanical lever arm and bowden cable attachment were fabricated to allow manual wastegate control. The top of the radiator is mounted against the firewall. The radiator leans back against the firewall at an angle of about 20 degrees from vertical. A fully enclosed aluminum shroud was manufactured to duct air from air inlets in the bottom cowling through the radiator and out the normal air exit between the rear of the bottom cowling and the lower edge of the firewall.
Coolant exiting the engine flows into a firewall-mounted header tank.
This header tank has provisions for a radiator cap, temperature sending unit, pressure transducer, and coolant bypass circuit. In order to fix the engine to a standard aircraft type engine mount, steel attach brackets were designed using the standard Continental isolation rubbers. The bottom mounts use the four stock Subaru engine mount points on each side of the oil pan. The top mounts use the top rear two cylinder head bolts on each side.
