zvhturbo - that wont help with Cosworth management which uses 4 pickup points - the EECIV flywheel has 32-1 (or 36-1 cant remember) so you'll need to have the flywheel machined and a bit of metal let into it to complete the 4 pickup points on 12, 3, 6 and 9 o'clock.

mine uses a bracket that has been alloy welded to the sump, a cosworth crank sensor and bracket and a pulley with 4 pickup points on it - works 100% and theres no machining of parts involved.

Paddy - Field Motorsport will modifiy your sump and pulley if you give them a bell.
