Hi everybody,
You might have read in my other thread that my ej22 is kaput. I'm considering a few options, one of which is putting an ej25 in as a replacment to the ej22.
My main consideration is obviously that of compatability - will the ej22s accessories fit onto the 25, i.e. p/s pump, alternator, a/c compressor? How about engine mounts and interface with the transaxle? What other considerations?
Like all things subi, it started as a thought and now it's stuck!
Cheers for your thoughts,
Owen.

Accessories might fit, but sometimes there are bracketing differences between year/models so might not.
It should be fine to go straight onto your gearbox, some models have 8 bolts, some have 4 but this doesn't matter. If you get a motor or gearbox with 8bolts to go onto a 4bolt one just leave the other four off. (these are the bolts connecting motor to gearbox).
Engine mounts will also be fine.
I think your main problem will be ECU and wiring-loom related. The EJ25 will likely have different engine loom plugs, differences with engine sensors and obviously a different ECU.

Hey Owen, very sorry to hear about your mishaps... At least the rafting trip was worth it by the looks of things...
I have next to zero experience in replacing engines so I'm not gonna be much help telling you if you can do what you are planning, but I really hope you find a way to make it happen!
Hang in there, mate!
