Questions on 99 Legacy Motor swap. Anyone?

Mike621 · #1 11-02-2007, 07:39 PM

Well, as some may know, I am trying to get a 98 or newer Legacy for Jon, my better half, and I have this deal secured on a 99 Legacy SUS (Outback Sedan) that needs a motor. I am trying to figure out what I can do besides the original 2.5L into it. I heard I HAVE to get a motor from a 99. I was wondering what Id have to do to use a motor from a different year or is an EJ22 swap possible? I just want a less expensive alternative. I don't mind swapping some exhaust parts... Anyone know?

(I did post on Legacy Central as well, but I just signed up, and wanted to see if anyone on here would know...)

I know the SUS is a neat car and that's about it. I almost bought one instead of the SVX.

I don't think you need a 99 motor per se...you just need a 2.2 that is OBD2 to go in there. Also note that the 99 legacy motor (2.2) is an interference engine so you know how that can go too.

There is a lot of talk about people doing this in their OBWs over on USMB so go do a search and have a good read over there.

I might even have something over there in the repair manual (that I am the moderator of) so have a look there too.

the 2.2 is not interference, only the 2.5L DOHC is interference.

the 99 2.2 is interference. Check your sources.

An EG33 ought to fit the 99 Lego quite nicely. After all it has the good gearing to start with, and it's lighter.

I never did understand why Subaru didn't use the EG33 in the Lego. I think the original Outbacks would have benefitted from even a "detuned" H-6

All Subaru engines after '96, even the EJ22s, are interferential with the exception of the '97 EG33. (And it's finicky.)

The '99 EJ22 is a hybrid of a 2.2L and the EJ25 SOHC. It was also used in the '99-03 Imprezas.

It is unclear whether an earlier EJ22 will swap. While a '95 EJ22 will swap nicely into the '96-98 Outbacks, after that there are issues with 4 bolt vs. 8 bolt bellhousing patterns and possible incompatibility of the ECU to deal with.

In fact, are you sure this is an EJ22? I thought I remembered the SUS having the EJ25 DOHC in it. (But it's really early, and I've only had half a cup of coffee, so my memory isn't at its best right now.)

i do alot of engine swaps on subys.
i just did an engine swap on my g/f's SUS 99. u can use any ej25 engine as long as you check the bolt pattern on the intake manifold. u gotta swap the whole manifold(wires n all) from the old engine to the new engine. this will solve alot of electrical problems.

also if ur car has an egr valve. u gotta drill a whole into the block of the jap engine (they don't come with egr valves)

hope that helps
