Replacing a 2.5L engine with a 3.0L

8737 Views 3 Replies 3 Participants Last post by  lockmedic
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.
