I believe the way the emissions regulations work is, if the engine was sold at a certain emissions certification it can not be changed. Not sure it has anything to do with the current application. You can contact Caterpillars TECC (truck engine call center) at 1-800-447-4986 and verify this. Make sure you have your engine serial number before calling because they will ask for it.
