I realize according to your opinion that fixing this motor would be best, and my boss says swapping motors would be best in his opinion. But what I'm trying to do is weigh options. If I can't make an 870 work, then be it. I just want to completely know why before I say I can't or can. I'm really not looking for opinions, but facts. If it's compression, injectors, pistons, cams, and timing, I could see that being a major problem. But as of right now, I don't know.

what I said is NOT opinion!!!>

and yes.. the injection timing, fuel-air-mix, boost requirements, .. literally everything required to run more modern engines properly is dependent heavily on engine model and its programming.

Your other statement of...

This is absolutely not a good statement. Its a clear sign that someone does not know much about how any of the modern versions of the ISX actually work. they REQUIRE IT TO RUN PROPERLY+EFFICIENTLY AND LIVE A FULL LIFESPAN - So if your h#ell bent on the style of turbo alone dictating what type engine you need, ... then like I said.. fix the 570 and be done with it.

FYI:: The VGT turbo on more modern versions of these engines IS THE VERY THING that sets the proper fuel-air-mix, keeps friction control in check, and other factors for the more modern versions of the ISX to run properly. REMOVING IT significantly shortens engine life overall,.. usually by about half or less. and if the vehicle has an engine brake then that goes to sh#it too.

What you are not understanding is that more modern engines RUN VASTLY DIFFERENTLY INTERNALLY!!! and have very different needs to run them (programming and otherwise) to get them to not end up with a very short lifespan after some yahoo slaps the wrong model engine control module onto the side of one and then proceeds to put than clunky non-vg turbo that the ecm can no longer control.

That is the stuffs of ignorant fools that like to say those things to others in the inter-webs. People who know nothing about modern diesel engine technology, and/or someone still living in the 1970's when a diesel engines had longer connecting rods, comparatively less efficient and more forgiving injection processes, and all of their other inefficient flaws. The internal combustion processes in diesel engines has VASTLY CHANGED in the last 20+ years, and a 1990's, 2007, 2011, 2013, 2017, and 2024 model engines operate vastly different from each other, internally, and the newer they get, the more of a far cry they are from something designed in the 1990's and early 2000's. <-- Those days where a diesel was a diesel ARE LONG GONE!. they may look similar on the outside.. but they are VERY VERY VERY different in their needs and how they need to run to make them operate correctly.

Your posts also seemed to imply that you are wanting someone on here to say what you want to hear, instead of pointing out the reality if it all. That is not going to happen. Around here,.. we know better.

What has been recommended has already been laid out (in earlier posts) .. and if your boss wants to 'swap to something newer', then they need to consider what that requires in total. What the benefits will be in the long term, any legal ramifications of it (as I am sure they will also want it deleted too), long term operating vs. maintenance costs ... etc. and not just some short-changed opinion.
