I have an 06 Forester 2.5 Automatic. Engine threw rod, will the 2.2 from my moldy 99 Legacy fit?

You would severely de-value your Forester by putting an old engine in it even if it did work and you would never pass smog inspection again. I recommend getting another engine of the correct type. Either a used engine or a rebuilt crate engine if you plan on keeping the car.
I would either purchase a brand new engine or get a new vehicle. Don't expect an engine from 1999 to be your long term solution.
Subaru engines are not too great on engine rebuilds, and an exchange engine is a dicey proposition, you don't know what you are getting. Actually, that car is 11 model years old, which is ancient for a modern vehicle. Do yourself a favor and get a new car.
Where did you get that tidbit Mark? You can rebuild these engines just fine and if you do your research and buy a rebuilt engine from a reputable shop your car should be good for a long time. Mark is just hoping he will get a bonus for selling a new Subaru.oil burner ;)
Ernie, didn't you make this point a while ago?? Maybe I'm wrong, BUT, I think you said it wasn't cost effective or advised.
On DOHC, yes. SOHC is fine. You seriously shouldn't respond to engine related questions mark. Seriously. Including this one. No, really. Please don't.

Mark, are you also conflating me with FoR? I hate Foresters, but if "rita"'s is rustfree and not in need of many more repairs then chasing a used SOHC w/ new gaskets and valve guides for under $2.5k is POSSIBLY a reasonable path. If tires, brakes, exhaust, etc are also required, or this F's getting rusty I wouldn't bother. Very gray area here....
Guru --- What is your professional opinion on rebuilding the SOHC and DOHC Subaru engines from an engineering standpoint? Are there any reasons other than economics that they cannot be successfully rebuilt?

Alas, the old DOHC rarely survives a rebuild for long. Same with the more recent turbos. But the SOHC 2.5i (and presumably its smaller brother the new 2.0i) generally handles new head work well. Bottom end rebuilds are much trickier, labor-intensive, and thus are better avoided. SOA is much more apt to replace a short block than rebuild a motor, for example. Note that I am NOT an expert wrt to bottom-end rebuilds nor boosted Subie motors as I avoid them as Subie's motors are best left unboosted and not thermally challenged.
No Ernie, I'm not confusing you with Walt. And, I guess I have a pretty good memory of what you said about "rebuilding Boxer engines" when you said they are much trickier and best avoided. I'm standing by my original statement....Purchase a newer car or brand new engine.... I would lean towards getting a new or late model vehicle..... Happy Holidays to you all. Peace.
Yes, I meant to say Walt and Full of Regrets... I know they both have distinct opinions about Subarus.
Subaru did attempt to "rebuild" oil burners recently but all they were doing was re-honing the cylinders and installing new rings (not sure about new pistons). That failed so they went to replacing short blocks. I am not sure that means that they could not be rebuilt by a competent machine shop or just that the feeble attempts by Subaru failed. I have a copy of the old Subaru shop bulletin and will have to re-read it.
