F-150 Adapt Diesel Engine

What do you think of installing a 4.0l Turbo Intercooler Diesel engine of the Isuzu Npr truck to my Ford F-150 Lariat Cabina 1/2 2004 Automatic to replace the excessive consumption of the V8 in the same original automatic box of the truck?

Good, in my opinion as a mechanic, I would say that it is not convenient, remember that these vehicles handle a very large electronic system, the boxes with the engines are dumbbell and it is probable that a big problem arises, what I recommend is to make an adaptation of a Toyota Hz engine with everything and its gearbox, I tell it because I made an adaptation like this Convenient to adapt engines without their own box "remain without strength and generate many problems.

Here in Ecuador there are not those engines, the only option are the engines of injured trucks to buy and mount them, here there is a silverado chevrolet with a Daihatsu engine delta in the same automatic box and super good wheel, good torque and everything, greetings.

Hello, compare the powers of the motors and the maximum revolutions and idle, so you can know if the final speed and for a walk will be maintained and the vehicle benefits will not be reduced dema.
If they resemble, it's a matter of managing them to adapt it.
In my case I adapted a box to a Nissan engine to which I had to cut the box housing to be able to put the other.

Greetings.
