The Nissan SD22 is a 2.2 l (2,164 cc) straight-four, water-cooled diesel engine from SD family, manufactured by the Minsei Diesel Industries, Ltd., which was renamed Nissan Diesel Motor Co., Ltd in 1960.
The engine was produced as MN 22 by Chrysler Marine (under license) for marine applications during the 1980s. The marine version, using a water-cooled exhaust manifold and expansion tank is also still available from other manufacturers.
The compression ratio is 20.8:1. Cylinder bore and piston stroke are 83.0 mm (3.27 in) and 100.0 mm (3.94 in), respectively. The Nissan SD22 engine produced from 61.0 PS (45.0 KW; 60.0 HP) at 4,000 rpm to 71.0 PS (52.0 KW; 70.0 HP) at 4,000 rpm of horsepower.
The SD22 engine was equipped with Kiki-Bosch in-line fuel injection pump on most vehicle models. The Nissan SD22 was used in the Nissan Caravan E23 with Kiki-Bosch VE fuel injection pump, in Taiwan the engine was used in the Nissan Atlas F22 with C.A.V-D.P.A. fuel injection pump.
The breakdown of the engine code is as follows:
- SD – Engine Family
- 22 – 2.2 Liter Displacement

Cylinder block
The cylinder block has a monoblock high-strength cast-iron structure with replaceable dry liners. The SD22 had two modifications with three or five main bearings. The engine has a drop-forged steel crankshaft with balance weights, all main and connecting rod bearing surfaces are induction-hardened. Bearings are the precision type, steel-backed tri-metal shell.
The Nissan SD22 motor has an aluminum alloy piston for high strength, lightweight and good heat conductivity; three compression and two oil control rings (before 1981) and two compression and single oil control ring (after 1981), they are chrome-plated for long service life. The cylinder bore is 83 mm, piston stroke is 100 mm and the compression ratio rating is 20.8:1.

I have a diesel motor in my boat, the valve cover has sd22 Nissan Chrysler stamped on it and says it’s 48 hp, do you have any info on this motor?
Information is not much.. It is the marine version of the Nissan SD22. Internally it is the same engine, but the manifolds are different and marine version has a direct coupled mechanical governor.
After research, I’m gathering that Nissan didn’t make a 48hp diesel, it sounds like they made a 48hp gas, and nissan diesel engines generate 60 to 70 hp engines, I’m thinking maybe the original valve cover was lost or misplaced, so someone put a gas Nissan engine valve cover on it. Can this be a possibilty??? I’d like to know what engine it is, so I can get it running, with new or rebuilt injector or possibly get injector pump replaced or rebuilt..
I have a marine version of Nissan sd22, Type 14 E, serial 404326. I need a Water cooled exhaust tank/manifold. Can anyone put me in contact with someone having one or a company still making one. My present location is Penang, Malaysia.
I can answer my own question. Manifold was manufactured by Thompson Foundry Ltd. Surrey, B.C. Canada. They still have them in stock for both sd22 and sd33 engines. Contact 1 604 596 9611 or info@thompsonfoundry.com. Jack Thomson.
Is your sd22 diesel a 48 hp or higher..
Where did u find the serial number?
Jay, I thought a lot about your problem, looked for information but found nothing new. But I have a question: are you sure that 48 is exactly HP and not kW (65 HP = 48,47 kW)
Hello
I just bought a houseboat that has two sd22 motors that I don’t need. The boat is not going to be moved. Using as a live aboard. What price range can I get for them? I don’t know what year the motors are from. I have the manuals as well
Hello Jay Mendez, What year are the motors? When you figure out what price you would like, I would like to buy at least one of the motors. Where are they located?
Im interested in buying one if you still have one
Can you call me to discuss

I’m in nyc. Selling both as a package deal with transmissions and fuel tanks
I would love to buy one of your manuals! The motor I have, the manual I need!
Thank you,
Dirk
I’d be interested in one of those motors
Patrick 612 209 8369 txt please
tengo problemas con un motor sd 22 pueden ayudarme?
Anybody have one of these sd22 motors they are wanting to sell for use or parts? I’d be interested in buying one
Do you still need sd22 engine
Also looking for parts or working engine.
I have two SD22 Marine engines that need work, but the basics are all there. (They were run out of oil.) Between the two, 8 good injectors, two injector pumps and at least one marine transmission. That’s easily $2,000 worth of engine parts in addition to the blocks. Any reasonable offers out there? Oh, yes, also have the manuals!
Captain Phil,
Greetings from Rockport, ME.
Can you tell me what do you want for both engines as a package?
Please advise

Hi do you still have the SD22
I need parts
Have two SD22 Marine Chrysler/Nissan diesels with all injectors and injector pumps plus at least one marine transmission. All or could part out.
I have an SD22 that ran for less than 100 hrs on a fish pump in Alaska. It is complete and in excellent condition. Seattle area location.
Hello Bill, you still have motor available I have one in my troller and am looking to replace having a spare would be nice. I’m located in
SF Bay Area and can be on my way asap if so. Thanks
Capt Phil…like to ask you…what marine transmission have you ? also what damper plate is used …would appreciate if you can help me cheers Ernst
I have a sd22 Honda engine I need a oil filter #
Honda? Spin on oil filter?. Or element type oil filter with the thru-bolt? The element type is a;

I have a sd22 in nm I would sell vary good engine
Do you still need sd22 engine
Can these engines be turbocharged
If so what would you recommend
Anyone know of a spin on oil filter mod for the Marine SD-22 (MN4-33), to replace the element type filter? Thank you.
Where can I find a voltage regulator for the sd22 Diesel engine?
I’ve got a 1983 Datsun 720 kingcab sd22 diesel with a manual trans. A garage took it apart and trashed the old flywheel on the fly wheel there’s suppose to be a extra mounting hole for the thing to mount up but every time I order one they give me a 6 hole flywheel needs 7 holes to mount it??
I have a 1981 SD 22 running motor complete came out of my Datsun 720 pick up if that’s what you need I have it I’m in Southern California 805-276-5304
I have a 1972 SD22 in a Nissan Civilian bus (Echo) and the inside parts of the element oil filter had been gutted when I bought it. I’ve jerry-rigged a system, but not original. Would anyone know where to find these parts? (I live in Costa Rica). Great page, by the way!! Congratulations!
