It is left hand drive (Japan cars are RHD) and it came with the exhaust gas recirculation (EGR) pump and pipes that I will be removing because the G Wagon exhaust manifolds are different, and mine does not have ERG nor a catalytic converter. This all suggests the M110 984 is the US-market engine.
But I am confused about what to expect with horsepower.
According to the Mercedes Engine and model survey, the M110-984 is a Model 114.062 engine is a "for USA" model that produces 130 KW@6,000 RPM (174 HP),
Other sources say the Model 114.062 engine is a m110.981
Despite checking numerous databases, I am unable to find the data product vehicle specification sheet for the 280E sedan. Would you be able to find out what engine I have in terms of performance? - Horsepower
- compression ratio
- regular or premium fuel, etc?

1) Engine Model & Serial #
Clean off the top surface of the cylinder block just behind the distributor. The numbers are stamped there.
2) I noticed that the chassis was LHD, hence non-JDM.
What you have termed an "EGR pump" is actually an air injection pump. Air injection into the exhaust gasses is a different system from EGR.
3) Although the M110.984 was supplied in the USA, it was also supplied in the rest of the world; it is the standard engine for W123/280E.
4) If the numbers on the block confirm that you have an M110.984, it will be 9:1 compression ratio, and 174 or 182HP, depending on version of intake manifold.
When the spark timing is set to "standard" specification premium fuel will probably be required. With a bit of retard, it will run on regular.
Can you post some pictures of the intake manifold, and the fuel distributor?
