Seems a few changes due to sensors and such on EFIs, that there isnt a whole lot of in-depth knowledge about. That can be found.
The 2.2L Patrick had came with a hole in the cover, and what looked like a brass cover a sensor went in. Its pulley had only 2 notches for reading TDC, and I guess 10 degree ATDC ?
Funny thing, my old Bitter cover on my 2.0L has a hole for a sensor, but its smaller than the 2.4L one. Add to that distance between the front of the Kadett motor and radiator. I am going to stay with the stock EFI on it and play with Bens Manta for the custom EFI.
