    Dieseltalk SD33 FAQ

    The SD33 family of Nissan engines are very reliable, strong, and ask for little in the way of maintenance. The engine uses industry-standard BOSCH injection system components (license built by Diesel Kiki) and is known world-wide as a reliable, long-lived powerplant.

    Info on Scout diesel MPG at the bottom of the chart in this link.

    There are performance upgrades for the SD33 series, mostly for the SD33T. Links to posts about those upgrades can be found below.

    Exhaust: Click Here

    Intake/breathing improvements:Click Here

    Propane injection:

    Injector pump "tweaks":

    Everyday-use improvements:

    David Lang has a "Performance Calculator" on his site, that gives good data on what kind of power can be drawn from the SD33 engine family with only some minor, proven upgrades. It also has several Gasser options too. To see his calculator, Click Here

    "Cartwright" a fellow Dieseler found some interesting information from Hastings (the piston ring people) about IH engines, mainly gasser stuff, but there is some IH D-301 and D-354 stuff in there ( for those of you restoring one of the 200 IH pickups built with Diesel engines :D)

    "There are cheaper engine kits out there for the SD33T, why can't I use them?" Click Here

    "If I want to buy a Noordeman Diesel overhaul kit, what will it cost me?"Click Here

    " I want to buy a Diesel Scout, what sort of things should I expect?" Click Here

    "How do I pull the cylinder head?" Click Here

    Want to know and understand Turbocharging better? Click Here

    The SD 33 engines use an SAE Flywheel housing, specifically the #4 size. While this makes optional transmissions feasible on paper, most SAE #4 housings were used for industrial applications, and not automotive. In the attachment box below you will find a chart showing the various sizes, number of bolts etc. for optional housings and hopefully this will make them easier to I.D. for you

    Pics that show the Flywheel Housing and SAE #4 to T-19 Transmission adapter.


    Rebuilding your SD33 yourself? You might want to put it on an engine stand, and here is the bracket that you should build to hold the motor.

    Thanks to Tom Newell for providing this diagram.

    Bought a circulation-style engine heater and don't understand how to route it properly?

    Here is how it should be set up.
    [​IMG] Thanks to David Dixon for this diagram

    The SD33T was a drastically improved engine over the SD33 N/A engine, many design changes were incorporated with the addition of the turbocharger. Many thanks to Treven Baker for sharing this page from his library with us.

    Diesel Engine Conversion Links

    A while ago, the Cult of the Diesel started some discussion threads about various engines for Diesel swaps. When the web site upgraded to allow a threaded view, a lot of these threads were lost in the archives.

    Well, I have found a way to bring them back :) Click on the one that appeals to you, and enjoy the read, and contribute your experiences, or your questions as you see fit.

    European Diesel Engines
    ITEC/ Navistar/ Ford Diesel Engines
    Cummins Engines
    Japanese Diesel Engines
    GM/Detroit Allison Engines (this thread has been altered to only include one discussion)

    I will add to this as needed. If you feel a link should be incorporated into this thread, simply PM me with the link, and I will add it after review.
