STR-DURA-2.0-2.3-03 Duratec starter motor

A new small diameter lightweight flywheel has been specially produced for the Duratec 2.0L & 2.3L engine. The diameter of 268mm has been made as small as possible, so that it still allows for a starter motor to be fitted to the engine block. We have produced it to accept the 5.5" (140mm) clutches. The new smaller diameter reduces inertia, so the engine will be able to accelerate faster. It is used by many competitors in racing, rallying and sprinting.
Must be used with the specially designed starter motor.

STR-DURA-F3-01K

This Duratec flywheel & starter assembly have been designed specifically to suit a F3 type installation. The diameter of the flywheel is 210mm overall and this allows for maximum ground clearance. We designed it for use in combination with our matching dry sump system which has a maximum sump pan depth of 25mm. The starter motor is mounted onto the engine block using the original mounting bolts but with a clever gear design arrangement, we have been able to pick up directly on to the flywheel teeth. The flywheel is designed to accept a 5 1/2" racing clutch.
