    I wanted to add a how to 4.2 v6 swap and split port swap.

    Here is a quick basic guide.

    This guide is similar to the one I followed. It is from another forum, click here.


    Even though the guide is fairly complete, I'd like to add a few things;


    1.You do NOT need a 01-up 3.8 oil pan for the swap.
    You can use an earlier oilpan and simply cut off 2 studs (this does not cause any problems or weaken anything.)
    I made a how to below

    2. You will need to do some custom work to the heating tubing.

    3. You will need to do some custom work for the fuel rail.

    4. You need to hold open the IMRC or remove and plug the holes.
    I removed the IMRC and plugged the holes.

    5. There is an extra temperature sensor the Mustang uses.

    You will simply need to drill and tap a hole for the extra sensor in the intake.

    6. 94/95 or 94-98 (can't remember which) the stock mustang headers are the best (obviously long tubes would be better)

    7. Use as much of the Mustang 3.8 parts as you can.
    Maf, injectors,upper intake(or windstar conversion)...

    8. You can try to get away without a tune. Its recommend you do get it tuned though.


    9. Emission controls are an issue (EGR).
    If you don't have to do emission tests, I recommend just removing all of it.

    10. Play will connectors and sensors (again, use as much mustang as possible)

    11. K member.
    (side note)
    The v8 and the v6 members are the same for the same year. But you need the correct motor mounts. If you have 94/95 k member use the 94/95 v6 mounts, if you have 96/97/98 k member use the 96/97/98 v6 mounts and so on.










    I think that's basically all. I'll update if anyone has corrections or if anything else comes to mind!

    Happy v6ing!
    :)

    My only question is, how do I tune it without a dyno? There's no dynos in my area, and I can't find a compatible handheld.

    I would contact VMP about remote tuning (email tuning).
    Like I said, remoting tuning should do the trick for a mild N/A setup. I strongly recommend if you go with boost to but it on the dyno.

    What do you mean you can't find a compatible handheld? VMP sells the handheld SCT tuner you will need for their tunes.

    thanks for this. I may be getting the motor to do this soon. I got junkyard wars going on here. Last time I was at each of them I was scoping out the good engine to pick.

    With what little research ive done and my experience from a 98 E150 4.2l....most of the bugs got worked out by 2002 and is a definite year in the clear for reliability

    f-150, e-150, the newer the better is how I look at it. If you're trying to just swap one in, I would definitely change the head gaskets before dropping it in (while the motor is out, much easier) and if you're that far into it, may as well port the heads and intakes.....o wait. sounds like my buid haha.

    98.5+ are all good.
    Mine is a 98, I happened to get the better engine.
