The engines are very similar other than a few subtle differences. The donor engine is only a couple of years newer so I do believe many of the electronics may be the same. Make sure you use a new gasket for any parts you remove that require one and use fresh, clean oil and a new filter on startup. While both engines are out, you can set them side by side and get a good look at what may be different about them. After doing a quick lookup for re-manufactured engines, the same part numbers show up for reach vehicle so the engines should be compatible.
