The car originally had the 2.5L and I am swapping in a 2.2L from a 97 impreza.

 

The ej22 does not have an egr can this be resisted out or do I have to drill the intake manifold and all that stuff to accompany the egr? I really would rather resist it out if possible.

 

What exhaust manifold do I need? I doubt that my 2.5l exhaust manifold will fit so what does fit both the 97 ej22 and my 98 Outback?

 

Is there anything else that I am forgeting?

 

Any help would be greatly appreciated,

Shawn

I just noticed that there are fuel lines going to the right front corner of the engine on the 2.2l the 2.5 does not have these fuel lines. What are they used for? IDK where my book is to look it up.

Those are for the charcoal canister. Go back to the yard and buy the canister.

 

I have a feeling you will get away with the EGR not being there.

I thought they were for something like that. I hope ther is a way to wire out the egr. I have to look into it closer.

Hold on here, your 97 2.2 does have an egr. I have done what you are doing. This ia a past post of mine

 

Going to make this simple for you as I have done the 2.5 to 2.2 on a Legacy Outback. I used a 97 2.2.

 

From the donor car (450 dollars tops)

 

1) Engine / use the exhaust manifold from the 2.2 donor

2) AC Compressor you must keep and hoses from your 2.5 mount onto the 2.2

3) Metal Power steering lines from the 2.5 move them over

4) The fly-wheel from the 2.5 will have to be moved over to the 2.2.

 

From Subaru

1) All new exhaust gaskets (10 dollars)

2) new o-rings for the AC hoses you disconnect

3) new o-rings for the power steering lines you disconnect

 

From Walmart

1) 2 cans of 12 oz refrigerant and a refill hose (30 bucks)

 

While you are at it replace this on the 2.2 donor (100 bucks) an easy to do with the engine out.

1) Harmonic balancer (50 ebay)

2) AC and Alternator belts (20 pepboys)

3) Rear cam seal (5 dollars)

4) Oil Separator Plate (sure to be leaking, original is plastic) (15 dollars)

5) Rear main seal. (20 dollars)

6) Spark Plugs (10 dollars)

7) PCV Valve ( 8 dollars)

8) Valve cover gaskets (2 of these) and grommets for the bolts (30 dollars)

9) Reseal the oil-pan and replace both gaskets that are internal. (RTV temp sealer 4 bucks, gaskets are 10 bucks)

My 97 ej22 MT does not have an egr. The AT does have an egr. So that is my problem.

Why are you replacing the motor? if you just swap the shortblock, it's a pretty simple swap. but if you swap the heads and intake, you'll need to get into wiring, and ECU.

 

the exhaust is the same, as long as your EJ22 is dual port. but if you're keeping the 2.5l heads, it won't matter.
