Power and ratio wouldn't be the highest ones, except if you do some tuning in the 4D56 engine. It can be perceived as underpowered, but the fuel savings would worth. I'm just not sure if the rear axle would fit, because the Crown Victoria is wider, but its Ford 9-inch axle has a wide range of gear ratios available, and a lower one would be desirable to make it feel less underpowered - with a lower gear ratio it will have a lower top speed, but quicker throttle response and better performance on hilly terrain.

What a miracle, you didn't recommend an Isuzu instead of the Mitsubishi :b
AFAIK it's easier to find a 4D56 than a 4JB1 in Dubai.
That seems to be too much tin for the 4D56, but actually if they can deal with a fully loaded 14-seater microbus there is not too much to worry about. Would just demand a low-geared rear-end. But would just be not so good to lose the automatic transmission.
Instead of a non-turbo 4D56 a good engine for the Crown Victoria would be a Kia J2. There were even some versions with automatic transmission that had been widely used as ambulance in Seoul, so the driveline can handle a heavy body-on-frame sedan.
Kia J2 is also a reliable powerplant, Winston, and considering the remaining ties between these early Kia models and Ford/Mazda engineering it could ease a driveline swap.
I believe a Kia J2 or the 3.0L JT would be the best options to a Crown Victoria.
There were some versions of the Delica/L300 fitted with the 4M40, IMHO more suitable to a heavy full-size sedan.
I was going to adapt a Perkins 4.236 in my grandmother's '04 Crown Victoria but would be nearly impossible to get it smog-checked.
Adding a turbo, intercooler (mine is water-to-air), engine oil cooler, messing with the injection pump and using a 3" air intake with a larger air filter the 4D56 gets mad, and possibly it would be hard for an original Modular 4.6L V8 to hunt it down.
There are many good options to fit the Crown Victoria, but if the intention is to get the swap done still in Dubai the 4D56 is the way to go. Also there are other options to get this engine already turbocharged from factory, so it could be also considered.
I live in Bahrain and currently own a 2004 Crown Victoria with the 4.6 V8 needing a rebuild. Now also considering to retrofit it with a 4JH1-TC. But for me the automatic transmission is a must because my left leg was severely wounded after a motorcycle crash, so since the electronic controls of the Ford transmission would not "talk" with the diesel engine maybe the transmission available as optional to the D-Max will be the most suitable option.
I'm from Rhiyad, Saudi Arabia, and the first time I heard about diesel swaps in Crown Vics was in the last year in Jeeddah, when a cousin of mine came out with the engine and transmission out of a wrecked Isuzu NKR willing to adapt it into a 2002 Crown Vic he bought with a severely damaged transmission. But the 4HF1 is quite tall so he ended up only swapping the transmission, but he went with a different one out of a Ford F150. The Isuzu diesel setup ended up in a Chevrolet B10.
Some people in my country, Brazil, use natural gas as an alternative for the gasoline, since diesel is forbidden for vehicles with a payload under 1000 kilos, except 4WD. Maybe could be as cost-effective for the Crown Victoria and not sacrificing too much the power.
My grandfather would love to get a diesel into my grandmother's Crown Vic. He has been considering to get a Volkswagen engine out of a Passat for a while. Since she usually drives a lot it could cut their fuel bill significantly. He already drives a diesel Volkswagen Jetta but she refuses to drive a front-wheel drive.
I have already seen a dieselized Crown Vic in Melbourne. That was a 98 model, fitted with engine (63kW 2.5 turbodiesel) and transmission (4spd automatic) out of a rolled-over Ford Transit from late 90's, with the 4.56 rear-end. That was a private import held by a guy who attended to the high-school in the States. Even had a good throttle response.
