ISX 2350 swap with X15 performance series

[City_truck]

Hello
I am planning to swap the ISX 2350 (in international) with X15 performance series ? Everything seems same (engine side) except (confused with) fuel system (injectors), turbo and ECM. I think technically it can be done but not sure about fuel system. Please share your experience on what needs to be taken care of when doing swap? I personally think that if I use old ECM, harness, turbo and injector then it should be fine but would like to know your experience. DPF and EGR is De-mandated.
Thank you.
