870 isx replacing a 871isx.

[herschel]

is there any way that i can possibly make this non egr 870 with a non electric turbo run in this 2009 pete without reusing all the 871 components. the 871 was deleted, egr capped,dpf gutted or have we ventured into a non repairable problem? seemed simple at the time just swap an isx out for another isx. how would you swap in a cat engine? do not want to add all the 871 crap to this block but if thats the only way i guess it can be done.
