    Default 403 electronic injection

    Has anyone tried to fit electronic injection to a 403 motor?

    i know the 1600 c/f cortina manifold aligns the ports well with 403

    does the ford ka have same port spacing , one wonders?

    You could use a 205 Si throttle body and get monopoint injection that way. Even an EA Falcon mono point throttle body maybe.

    Does the 403 have inlet ports ?

    From memory there is just a "trough" with a steel cover plate over it.

    You should be able to weld in tube piece/s to the plate and use almost single point injection system.

    Yes, just a trough. You would need to fill this with Devcon then make individual ports to be able to use multi point injection.
    Use Megasquirt 1, nice and simple. Keep the original distributor and trigger the ECU off that.
