    Default engine swap input

    I have a 90 7.3l IDI in my metro looking to swap out for a 93 7.3l powerstroke that is in a E350 van. this Thread is So I can hear pros and cons what additions that I will need to complete the swap any thing you have to offer than fire away lol !!!!the reason for the swap idea is 1. my engine isnt producing heat to the truck,tried new therostats, WP's, flushing and im getting black fuel like slime in radiator, not overpressurizing though, NO ANTIFREEZE IN OIL, smokes light blue somewhat and at times. hard to turn over at first.

    To me it seems like I got a cracked head and a faulty inj pump but not really sure thimking of rebuilding but was just givin this other engine that is still in van and runs well although it does have 289k but on the other hand my motor has more mileage than that

    You have got a lot going on there.
    Multiple issues, which in the end can still be a cracked head or bad head gasket.

    First the slime in the radiator, could be a bad oil cooler, could it be engine oil or even tranny fluid that you are seeing? It all looks milky brown or gray when mixed with antifreeze.
    Second, hard to turn over, you mean like 1/2 a turn then stops? That would be indicative of hydrolock. After the pressure bleeds off it cranks normally? Or could it just be a worn starter that is dragging?
    Thirdly, Smoke, could it be steam? Are you losing antifreeze ever? Could be pump timing, or air leak in fuel system as well.

    The lack of heat is most interesting, Do the heater hoses get warm? It is the highest point in the system and it seems a compression leak goes to the heater core and air locks it.

    So yeah already have all of those assumptions it looks like.

    Well, with a power stroke swap you need a complete donor. All the wiring and ECM. The tranny you can use but I think you will need to update the solenoid pack in the transmission. That would depend on your donor.
    '93 would not be a powerstroke. It could be a turbo diesel IDI, basically the same block that you have with a factory turbo on it. Powerstoke didn't start until 94.5 so maybe the year is wrong? Or someone doesn't realize what they have?

    That is a power stroke then. Cool.
    Yeah drop it in there.
    The ECM should be swapped to one with a manual transmission, but I think a chip will override that if you get a chip for a manual transmission.

    Actually I have a ecm for a manual and need one for an automatic now that I think about it. We have a '95 donor that we are using to put in our '86 four door.

    IIRC the oil Coolers need to be swapped too, just like IDI van diesel to pickup.

    Thinking about this some more.
    There are probably some issues with the gauge panel. Things I figured I would work out when I got there.
    I don't know if the sending units are the same to make the factory gauges work. I am sure there is a way, but not sure what that is yet.
    Items like the cruise control, tach would have to be figured out as the PSD and the IDI use different technology.
    As far as the oil pressure or temp gauge you should be able to add an IDI sending unit to the PSD to make those work.
    Your speedo should be the same, your sensor is in the Differential? Or yours is run by a cable?
    Radiator support would have to be modified if you are using the PSD radiator.
    Things like adding a check engine light would be important.

    Fuel system should work just fine.

    Your 1990 should have a cable speedo. Also all the gauges should work. The instrument panel should have a check engine light that can be hooked up to the PSD PCM. Tech gauge should work with wire splice into PSD PCM wiring. The hardest part will be adding VSS for the PCM to know the speed of the truck. Your 90 should have place in the firewall for the PCM to bolt in. That will make the swap easier.

    The PS didnt come out till 94/95 the van isnt a 93. but I wouldnt add a bunch of computer junk. Price some injectors for your IDI, then for a PS. you;ll see what I mean.

    The engine itself should be a bolt in. It just takes time to run all the wires.

    I am sure rather than swapping rear ends someone makes a transducer to send a signal to the computer. Then again it may be easier to swap rear ends.
    If you have a Van donor does it have a disk brake rear end?

    Depends on if you'd rather cut + weld or do wiring. I'm planning on putting in a dt360 I bought cheap. Everything about it is better than the powerstroke, idi, or even cummins, other than it's heavier (you swap the pump for a built cummins one). It's so built on the inside that you'd only ever have to upgrade the fuel and air. They're totally right about the PSD parts, too much $ for not enough (umph) in my opinion. Dt360's are readily available, and I've seen many people lose enthusiasm with a project when it finally comes to the heavy wiring.

    sweet! someone besides me on this board that is NOT on the PSD bandwagon.

    I agree the DT360, or the Ferd 401 are much better start points than a PSD. The IDI is the only Cornbinder v-8 dismal that does anything for me, economical, bullet proof, and one wire. Should I need more (and there is a BUILT TO THE NUTS one on PSN),, straight 6 or Duramax... Baby

    I only say Dmax, cause I like the Allison, and it would really bother the blue oval boys to see THAT 6.6 under the hood.

    dt360 is a international diesel engine that was used in the medium duty trucks, it had a sister dt466.

    Very common engine for dump trucks, single axle trucks for in town delivery. Simple design, easy to build up. Cheap to rebuild.

    Helped a guy put a 466 in a 79 ford f350. That is about all it is good for a pickup engine.

    I have had such horrible experiences with that series of engine I would not put one in anything you had to depend on. That is just my opinion though. I know there are plenty of people that have had great luck with them.
