I didn't mention it, but meant to say some diesels have a hard time breathing.
While shopping for a 1 ton truck recently, I drove alot of older ford 7.3 NA diesels from early 90's .. and compaired tot eh turbo'd 7.3's.. well.. there really was no comparison.. the turbo'd units have more get up and go. and at highway speeds when you stomp the smoke pedal.. the turbo'd units actually respond, even when already crusing at 70mph.
in ford tractors, I have a 5000 NA, and a 7610s turbo.. have driven a 7000 which is basically a 5000 with a turbo. I have also driven a 5000 with an M&W turbo kit. The turbo'd models win hands down in my book. the extra 7 minutes needed to warm up ( 5) and at shutdown (2) are non issues. As far as repair.. well.. run clean oil of the correct grade and change at correct intervals. fix broken manifolds if you find them, and observe shutdown and startup procedures. over the years I've had various turbocharged gas and diesel products. I've only had a problem with 1.. it was a gasser pontic car.. I was a teenager.. I ran it hard, didn't change the oil often and put it away hot. it eventually ate a 700$ turbo. after that.. I did the oil and start/.shutdown by the book.. car had no problems for years.. sold it to a buddy who used al lthe good out of it, then gave it to his brother.. finally it got junked because it was ugly and interior was bad.. car drove to the junkyard just fine.
as for your kubota comparison.. I'm not up on those models.
do they have identical bore and stroke? same compression ratio? any difference in pump and settings?

My M7040 only has 1-2 HP difference between N/A & turbo model, but I'd guess the torque rise is better in the turbo model. From what I'm told by mechanic & dealer salesman, only reason turbo was added was emissions.
My NH is 108HP turbo and the turbo gets on my nerves after a long day of use. My NA Kubota seems more relaxing to operate.
