I am considering replacing my Subaru 2.2 engine with the Subaru 2.5 engine.

Are the engine mounting points the same on both of them. Or will I have to make new engine mounts.

Also will the reduction drive on the 2.2 fit the 2.5

Yes and yes.

Chuck,

I am in the beginning stages of doing the exact same thing with a used gyro I purchased. I spoke with an expert Subaru repair shop owner yesterday who told me the engines are the same externally for mounting points and gearbox/reduction drives.

IF ANYONE HAS A RUNNING 2.5 SUBARU THEY WOULD LIKE TO SELL I'M VERY MOTIVATED.

Also, I have a non-running 2.5 that came with my gyro. If anyone has a recommendation for a shop or "a guy" that does quality rebuilds I'd be grateful for a recommendation.

Eric
