Crank Position Sensor - Get a cosworth backet welded to your alloy sump and 4 lugs to the bottom crank pulley.
Phase Sensor (emulation of the sensor inside a cosworth dizzy) - Get a bracket off of Gadget or Jano that fits on the head and reads off a disc behind the cam pulley. Or you can get a hybrid dizzy that uses parts from a Cosworth and a RSTurbo.
