    Do you know what market your engine was originally sold into?

    Regarding the injector lines, there's a thread on here somewhere (just been searching, can't find it) of Andrew E (there are a lot of variations on that username) doing the manifold swap on his 4BD1T to that 4BE style. If injector lines needed done there should be mention of it.
    My motor was apparently from a 1990 NPR 300 that had rusted out bought it in Canberra there is pictures of it on my thread Tales of two motors.

    Ah I see now. Yours was a non turbo NPR 4BD1?
    I found the thread but the pics are a bit small to make out the details.

    But I remember the truckasaurus story.

    The mystery deepens.
    Jerry can you take a look at the pic in this auction? It looks nothing like yours.

    I'll have a good look at mine in daylight and compare the two

    Right, I knew this scroll type manifold rang a bell. Isuzurover has one in this thread here:
    http://www.aulro.com/afvb/isuzu-land...ml#post1002748



    Anyone want to make the call on whether it'll fit or not? I'm also wondering how many psi it takes to pop one of those frost plugs out.

    They dont look to have enough depth to be a normal welch plug, so I'm guessing they are just a slightly domed disk, and may even be swaged in slightly.
    In which case I'd guess the PSI required to pop them would be more than normal turbo would put out.

    We will find out. Still not sure how I'm going to get air in this thing. The rear port will be blocked or mostly blocked by the steel mount with the bell-crank and air/oil seperator. The front will be blocked or mostly blocked by the fuel filter and brackets.

    Not to mention injectors lines

    hi dougalm

    i replaced once of these on my 4be1 and put a standard 4bd1 on. Did this so I could drop the seat box as it is in a 2b fc.

    Very challenging getting cylinder 2 lower bolt in and out....think little hands...

    Can not notice the difference in performance to be honest...its slow or slow....

    Good to hear. Do you have a rotary pump 4BE1? The later ones appear to be inline pumps.
    Going back to the older manifold you wouldn't notice a performance drop, but you might see some smoke or higher EGT's.

    Raining here so I pulled out that 4BE1 scroll manifold and threw some solidworks at it.

    In a nutshell it won't fit a truck motor without some minor mods, it will foul both the fuel filter bracket in the front and the accelerator brackets in the back.

    But that's not my concern. I'm passing this one along to someone with a greater need who disposed of those brackets long ago.


    Hey Dr Ben, do you want to run some CFD on these?
