    Its not a bolt on. There are slots cut in the cylinder head intake ports to allow the injector flow to atomize properly in the port. That's assuming your engine is carburated.

    Then there's working out the high pressure fuel pump to feed the FI. It's going to be more work then what you think- definetly not a one day job.

    Where to put the ECU, wiring, fuel pump, and a possible head switch . Not all heads have the upper 10mm intake bolt holes for the FI manifolds. Strangely all heads with FI mount holes do have the carb intake holes too! Not fair!

    Yeah, possible, but not simple...

    Hmm...I have F.I. and want "carbies". I used to run the early SU's on my 77 280 until I came back to CA and I LOVED them. Much easier to from F.I. to carbs. I'm with the others, possible but not simple or a one day job.

    Find yourself a MR30 skyline, it has a L24e engine in it,
    swap the head if need be (NM47, or the whole engine), and all the fuel injection bits,
    I original did this on my 240K, but now I moved onto megasquirt II

    I picked up a N47 Head with the EFi setup as for a 1 day job the car will be stripped for restoration early next year an a complete rewiring will be done so no issue

    If you are going to all this trouble, I would look for a Maxima N47 head. They are not the same as a 280Z head.
    The 280Z N47 will lower your compression ratio (on a L24) where the MN47 will give you about 10:1 and you dont have to notch the cylinders for the bigger valves.
    Thats my 2 cents...
