The ISBe in europe, manufactured in England by Cummins is a rear gear train engine, made for industrial use (ie Buses, Delivery vans).
The ISBe is also in the ECHO family of engines along with the DCX 03 Model year Chrysler, ISB02 ECHO all these models share the high pressure common rail fueling (amongst other new features).
I cant really go into specifics, but all models are built to accomplish their assigned tasks.
