How to check Subaru 2.5L timing belt/pulleys

Thank you! This is just what I needed to see

You are very welcome!

Wait…you never inspected the actual belt? Why didn’t you rotate the crank to check the belt for any cracks or deformities?

I could have but it was replaced about 10k ago

Hello and great video! I bought a 2004 Impreza 2.5L turbo wagon that had the original motor pulled and replaced with a 2.2L from an unknown Subaru model. The kid pulled the 2.5 and put the whole 2.2 with its intake and manifolds into the car. It is difficult to start and when it does start it backfires a lot and has very poor power and stalls also. Someone online thought I should swap the 2 cam sprockets and crank sprocket to fix the issue. Assuming the motor is good, since he bought it from a local reputable Subaru mechanic, should I remove the old 2.5L's two cam sprockets and the crank sprocket, and put them on the 2.2L block? I have the old motor, everything but the heads.

That’s really above my pay grade, do they need replacing? Has it always ran rough after the swap? I know the wiring can cause issues including engine control modules, even if it’s plug and play
