Aside from it being illegal to do such a thing ... That is unless the whole aftertreatment system would also have to be swapped over + it needing to be registered as a 'glider'?.

Also, any repair shop that would install just the engine would be as guilty, and can get fined heavily for participating in it too.

Just something to consider, as not everyone is willing, or is able to take that risk.

The best move is to simply source and put the correct model engine back into it instead.

Personally, I could care less, I just thought people should be aware of it...

legal warnings aside...

The X15 engine, as is, and all components can be run just fine, including injectors, etc. with the older ECM and older wiring harness. A custom program will have to be made for it though, as someone will need to make all the adjustments for the different air flow, different compression ratio, different injector trim logic, and other things.

I would recommend however that the turbo off the older engine be used if it is still good +_ something does for the air compressor intake, as the older turbo style has the correct speed sensor on it, etc. for the older engine wiring harness. The newer turbo can be used, but the speed sensor will be an issue otherwise.
