I have a cracked head on my '03 Outback 2.5L, how much of a problem is it "upgrading" to a 3.0L engine?

Are there compatibility issues with the transmission? Computer? Does anyone have any experience in this kind of thing?

Cheaper to go buy a 3L ob ready to go. All sorts of stuff doesn't match up and needs to be yanked, purchased and replaced to do that mod.

Get rebuilt 2.5 drop it in and save your self some money. Heck I could afford to go out and pay cash for a new 911 today and wouldn't even want to spend the time and money trying to fit a 3L into a 2.5 OB.

Thanks for the quick response. Ok, was just wondering if it required much more, and hadn't done any research (just lazy, I guess).

I've done it; fairly recently in fact.

Trans and rear diff need to be swapped, computer and entire front body and engine wire harness and the dash harness need to be swapped, as does the cluster and a host of other things.

It's not terribly difficult, just time consuming and you pretty much need the donor car beside you (how I did it). I would NOT buy a used H6 engine only with aspirations of shoehorning it into an H4 car. You will go broke buying alll the stuff you need but didn't get.
