    I don't know of any places that deal with the Central Fuel Injection (CFI) systems, most fuel injection stuff is for the sequential systems. You're best bet is probably ebay if you want to stick with the early fuel injection systems.

    The easiest way would be an 86-93 swap. The CFI is not at all well supported in the aftermarket for one.

    However, they are cheap and not hard to get, so if you got all the stuff from the donor, it would not be a hard thing to do.

    If you want it all to come UPS, try an Edelbrock or Holley, as they both make a stand alone efi setup.

    The 85 system is CFi and is basically junk. Get the system off of an 89 and up mustang from a salvage yard with mass air. this is the way to go. Try MPSAutoSalvage.com or go to your local junk yard and start picking parts.

    Good to see someone wanting to convert from carb to efi :nice:
    We see too many threads on guys wanting to ditch the efi :nonono:

    So what will you need from ebay or the J/Y
    A9L (manual) or A9P (manual or auto)
    MAF meter / MAS sensor
    Wiring harness
    Fuel Injectors / Rails
    Upper / Lower Intake
    Throttle Body / EGR Spacer
    EFI Fuel Pump
    Fuel Lines from Tank to Block


    I am sure there is more but... :shrug:

    Keep in mind that these parts don't have to come from a Mustang.
    The intake on an Explorer will actually be an upgrade to the factory Mustang efi intake.

    Good Luck,
    jason

    I agree completely...FI rules. The only thing else I can think of is if you're swapping from carb to efi is the tank. I ended up having to swap because the pre-EFI stangs only have one hole (combined sending unit and pickup tube). You can use your tank, but you'll lose ability to monitor your fuel level. As it is, I still have yet to wire up the sending unit that's in the tank, and install the gage that actually matches the impedance on the EFI 'stangs.

    I ended up spending about $1200 or so for:

    computer
    harness (free from friend)
    Cobra intake
    sensors (all of them!)
    braided fuel lines from the tank to the rails
    injectors
    TB (no egr spacer w/cobra intake)
    distributor
    fuel pump
    and a host of other new parts

    You can get away with much less, but I wanted to make damn sure I did it right...

    Overall the most important thing you need is patience...but man, it's well worth the time. I noticed an immediate increase in fuel mileage...with the exception of when I lay on the go pedal. It took me three days from start to finish by myself to do the swap, including an engine change. The only help I got was from my wife when I was stabbing the new engine.

    Best of luck to you!
