Got a hell of a score yesterday at work.  93 impreza wagon, 4EAT with a blown 1.8L.  I just happen to have a 96 2.2L EGR motor sitting on the floor in the shop


My Idea is to use the 2.2 block with the 1.8L intake.  Reason I'm asking is because I rarely work on the 1.8L, I'm more of a 2.5L nut. 


What issues am I goin to run into using the 1.8L intake on the 2.2?   Am I going to need to use the 2.2 injectors or computer to make sure its gettin enough fuel or is this swap just plug and play?



thanks dudes and dudettes

you will have to use the EGR pipe that is on the ej18.


when swapping the other way, the injectors on the intake work just fine.


the ej18 may / will have hoses for ''air injection?, not sure how that ties in.?

the ej18 also has a metal line attached to the exhaust on the passenger side head. i think this is also part of the ''air injection'' system. the ej22 will not have this. so i would look to see how to delete all of that. hopefully there are no ''sensors'' connected to that system.

I didnt notice any any injection things on the motor.  All differences were intake side, differences like where the throttle body coolant lines hook up. 



Oh yea, Single port exhaust, forgot about that part..  Gonna be a fun one to find, I know I have a single port header somewhere, but its buried under 2 feet of snow LOL..



We scored 5 2.2L engines, 1 2wd EAT and 3 5MT trans that all came out of running cars for a 1000 bucks @ the canadian border last weekend.  Looks like I got a spare 2.2 to throw in my Loyale.


Gotta love the Canucks and the rules that keep them down to very few cars in the impound yard, so they yard the motor/trans out and crush the rest of the car

the fuel injectors/ECU don't matter.


if you bolt the EJ18 heads to the EJ22 short block then it's all simple.


if you use the EJ22 long block then you'll have to contend with some minor issues/work arounds.  obviously the EJ18 intake bolts right up to the EJ22. it's a very straight forward swap, the issues are simple ones.

1. the single port exhaust

2. the EGR piping and metal tube piping john mentioned on the passengers side.  EJ18's have that, don't know if it's all of them but I thought it was - it's way down low, under the valve cover so you may have missed seeing it if you only looked from up top.


and you won't use the knock sensor in the EJ22, just remove it or leave it disconnected.

got most of it done today and decided to stop and go wheeling.  This ej18 didnt have the air injection stuff on the passenger side head.  I gotta dig up a single port exhaust and it'll be ready to go.


thanks for the help

interesting.  wonder if it's because you got them from Canada, are there emissions/engines different sometimes? 

either way you're done, good job!
