2250 replace a 2350
Hey guys we had a crank break In a truck it's a 2012 isx cm2250. My boss located a complete 2016 isx cm2350 and we are wondering if it's possible to drop it in or is there to many differences.
Thanks Curtis

RE: 2250 replace a 2350
The emissions system wiring and control circuits are quite different.

I have seen a few guys take 2350 engines and put on all 2250 wiring + 2250 ECM. The ECM needs custom programming for it to work correctly like that. The 2350 has higher compression ratio, different injector designs and spray, different boost requirements, and a few other things that require compensation for it to run right.

- I have had to straighten out a few for people that a couple dealerships have sent to me because they just would not run quite right. Apparently there are some OEM shops out there using 2350 blocks to replace 2250 engines.
