If you have an MFi turbo engine, either swap the pistons/rods into the efi bottom end and drill the oil return (oil feed just runs from the oil pressure sensor union) or drill the Mfi bottom end to use a crank position sensor, and use the Efi flywheel - failing that you can buy cps kits that use a trigger wheel on the pulley side of the engine?
Then use your EFi head and you are away!
