hey all,

I've got a good ol' '99 Outback Sport that I really can't part with -- but she needs an engine.

1) any tips on where/how to look?

2) what I REALLY want to know -- can you drop in a 2.5 in place of the 2.2? I've seen on other forums that this is possible, but was directed here for specifics.


I know this is gonna kill my wallet, but she's worth it.

if it was a 98 or earlier this would be a simple yes - drop the right EJ25 in and go, there's hardly anything to it.

in 1999 the EJ22 went to Phase II and incorporated quite a few changes. my guess is you can still swap but i haven't done it and don't recall details. have you tried searching - keep your eye out for Phase II SOHC EJ25 info.

it might be as simple as swapping the intake manifold onto a newer SOHC Phase II EJ25 with the possibility of swapping the cam sprockets. that's my guess.

the 2.5 has more headgasket (type it in google or search here to find all you could possibly care to read about it) piston slap and lower end issues. personally i'd just swap another EJ22 in.

What's wrong with the original engine? If you are looking to get 2.5 power and not have to worry about wiring and stuff like that do a 2.5 shortblock hybrid motor.

Any 2.5 shortblock will work. I used a 96 phase 1 2.5 shortblock. I had to swap out the crank timing gear. It's a fairly cheap swap and you can get some good power numbers.

PM me if you need info on this.
