m11 swapped for a n14

Hello i've got a 1997 freightliner fld120 with a cummins m11 celect+ and its do for a rebuild. I was thinking about turning up the power in it after the rebuild but now i'm thinking it might be better to just swap the m11 for a n14 celect+. So i've looked around trying to find if anybody has done this but i couldn't find anything. I have read that the sensors and the ECM are the same but i'm not sure if the air to air and radiators are the same.

If anybody knows anything about swapping a m11 for a n14 it would be much appreciated.

 

Thank you for the relpy.
That is what i was hoping to find a fld with a n14 in a salvage yard to get parts off of. From what i can see in pictures the radiator looks the same but the air to air inlets on the n14 engines are on the top while the m11 is in the middle of the intercooler. but i did see one picture of a 93 fld n14 with the inlets in the middle but they said that was rated at 400hp. do you think the air to air would need to be changed?

 

Thank you for your reply.
To answer some of your questions
Fixing what I have is one of my options but I can not sell the truck because it is hard to find a truck with the specs that I need for the job (20k front end, double frame or single thiclick frame, 245 wheelbase). My job is picking up bulk milk from farms and taking it to the milk plant. And that involves a lot of stopping and going up hills. That's kinda why I would like more power. I have done a lot of searching for a truck that meets all of our requirements and we recently found one after searching for a year. So that will be the truck I use while my truck is being fixed or swapped. I have plenty of time but whether it is cost effective or worth it to swap engines I've been debating with my mechanic and my boss. The mechanic of corse says he can do it. And my boss says it would be nice to have more power but he is concerned about the cost. We got a estimate for a rebuild costing $27,000 for a inframe. I'm not sure how much a complete, rebuilt n14 would cost. I guess I'll keep searching for a truck.

I really appreciate all of your input.

 

I was told the inframe includes new turbo, injectors and a remanufactured head. My boss added new front and rear engine seals also new power steering hoses.

 

Ya thats what I was thinking. That's why I thought maybe just swapping in a n14
