Default 2.5 interchangeablility

Hey guys. I've been asking around here and have gotten some mixed messages but I am hoping someone can tell me if a 2007 2.5 from a legacy will bolt into my 2000 Outback? My engine is smoked and I found a great deal on a 2007 2.5 with 22k. What will I have to do make this swap possible?

Edit: Sorry I should have clarified, I know the engine will bolt up as per moderators sticky but I am wondering if the wiring harness will work with the 07 sensors or will I have to swap manifolds, heads, accessories, etc.

Thanks

Andy

they are both Phase II blocks. you should be able to just use the long block from the 07 and keep the intake and all from your 00.

i beleave your intake will bolt up to the heads.

I'm not sure I could quote you even if I tried! I'm not even sure if that was English.

Andy, I think you would probably have to swap your intake and heads onto the '07 shortblock. The reason I say that is due to the fact the '06+ engines have iAVLS on the intake cams, so the heads and cams are different.

It may be that your '00 intake would bolt onto the '07 heads - I'm not familiar enough with the bolt patterns to say for sure. But that still leaves a couple issues:
(1) What are the crank and cam position sensor trigger patterns for the '07 vs. '00? In particular, the cam position is almost certainly different due to the iAVLS.
(2) Would the car be a dog with iAVLS cams that are (I think) always going to be on the low lift lobes? (Theoretically you could fix that with an RPM trigger switch that would trigger the iAVLS solenoids. Could be a cool thing to play with, if you're into tuning and experimenting a bit.)

I'd bet you could get some good money for low mileage '07 heads and cams. So I'm thinkin' you should go ahead and buy the engine, swap the heads and intake, and then sell the '07 parts to recoup your costs.

Funny.

Thanks for the great reply Pat. I will keep you informed on what I do and compatability of intake on the new heads.
