Cm570 help

[Corzlot]

I have a case ih stx 450 with a cm570 in it, with loads of problems. The boss is ready to swap out motors, but what would it take to put a cm870 in it? I understand the major emissions that would come with it, or is there a way to swap ecms and delete the emissions. This could be crazy on my part, but that's the direction we are headed. We can't find a used cm570 to drop in at the moment.
