I dont know anything about the 2.5 is it worth it or should i just find a Ej2.2...?
is it any more difficult to do the 2.5 over the 2.2?

that ej22 is considered the best motor made by many in the subaru world
the 2.5 will offer you a little more horsepower, but will cost you greatly in the reliability department, and they require a tad more room as they are quad cam...unless you go with the SOHC 2.5 which is badass, but all phase 2 and obd2...wiring headache compared to what you just did.
buy another donor car and have at it buddy...i might have another soon

The only issue with the EJ25d is the headgaskets. If the headgasket is caught early and replaced with the updated one, they're good for the rest of the life of the engine. If some one ran it overheated for a long time, the rod bearings can spit out soon after the new headgasket is put in.
They're not bad engines. And the power out of them is respectable.
I tore a lot of drivetrain parts up with a 2.2l, so I can imagine what I'd do with a 2.5.
The clutch will be more of a concern with the 2.5l if you're running an EA transmission. Use a high performance WRX clutch disk, XT6 pressure plate and the flywheel cut to XT6 specs and it should last a while.

Do the Frankenmotor - you will like that. As noted there is nothing wrong with the EJ25D except the expensive-to-work-on heads, headgaskets and the potential that a used one has been overheated and comprimised the internals. Otherwise they are great engines and with 2.2 heads and torque cams on them they scream.
