RallyKeith Posted June 20, 2005 Share Posted June 20, 2005 It looks like my dad is getting a 95 AWD Auto Impreza with an EJ18 that is blown. We have a few EJ22 motors lying around. Can we swap one of those in, and if so what would we use. I'm guessing that we could just use the EJ18 intake, wiring, and sensors, and slide the EJ22 Block and heads under it and it would work. Thoughts? Keith Link to comment Share on other sites More sharing options...
baccaruda Posted June 20, 2005 Share Posted June 20, 2005 i don't know but someone on nasioc or legacy central probably will. i'd guess that you can though. Link to comment Share on other sites More sharing options...
subaru_styles Posted June 20, 2005 Share Posted June 20, 2005 just take the 2.2 block, use the ej18 heads (to obtain a higher CR, 11:1:brow: ) and the ej18 manifold, as it is better than the ej22 one Link to comment Share on other sites More sharing options...

Thanks for the input though. I may have to consider doing that to my Step-father's 1.8 slug. Those little 1.8's are ok unless you want to do major 70mph highway driving. Then they can't seem to get out of their own way. Keith Link to comment Share on other sites More sharing options...
ballitch Posted June 20, 2005 Share Posted June 20, 2005 as long as you get an EJ22 with the same engine harness plugs as the EJ18 thats in there it will literally bolt up and wire in like nothing, if engine harness has different plugs, just swap EJ18 engine harness onto EJ22 motor, and your done. you can use the same MAF and everything, except make sure you have the same kind of heads as the EJ18 or else you will need to get different exhaust headers. ~Josh~ Link to comment Share on other sites More sharing options...

baccaruda Posted June 21, 2005 Share Posted June 21, 2005 oh really? that sounds good *evil grin* ... what about cylinder/valve interference? just take the 2.2 block, use the ej18 heads (to obtain a higher CR, 11:1:brow: ) and the ej18 manifold, as it is better than the ej22 one Link to comment Share on other sites More sharing options...
JWX Posted June 21, 2005 Share Posted June 21, 2005 they're already interference engines, so why does that matter? unless you are talking about while the engine is running? Link to comment Share on other sites More sharing options...
baccaruda Posted June 21, 2005 Share Posted June 21, 2005 the old 2.2s are noninterference Link to comment Share on other sites More sharing options...
ballitch Posted June 21, 2005 Share Posted June 21, 2005 the only things to worry about with EJ18 heads on EJ22 block is the thinckness of the head gasket and the timing belt tensioners, the EJ18 heads are the tiniest bit closer to the crank than the EJ22 heads, like a couple thousandths or something. that will, in theory, make the tensoiners work harder and breakdown faster. i say dont screw witha good thing. yes the EJ18 ECU will rune the EJ22 just fine, the computer will compensate for the extra displacement. ~Josh~ Link to comment Share on other sites More sharing options...
LPGsuperchargedBrumby Posted June 22, 2005 Share Posted June 22, 2005 yes the EJ18 ECU will rune the EJ22 just fine, the computer will compensate for the extra displacement. ~Josh~ correct me if im wrong but if a ej18 ECU will run a ej22 then a ej22 ECU should run a ej20 N/A i ask this because a friend of my'n has had the usual accesory pully problem with his ej22 , half the drive key is still stuck in the timing belt pully so he can't get that off and the bolt has broken off inside the crank and we can't even get a drill to go into it because i think its work hardend(drill was freshly sharpend and it wouldn't even look at cutting into the bolt) ej22's are very uncommon here so getting another one is out of the question however ej20n/a and ej25's are very common would the ej25 run on the ej22 harnes?

Tbird Man Posted June 22, 2005 Share Posted June 22, 2005 it should, can't say for sure. Link to comment Share on other sites More sharing options...
ballitch Posted June 22, 2005 Share Posted June 22, 2005 yes it should, as long as you swap the motor harness onto the intkae of the ej25 or ej20. ~Josh~ Link to comment Share on other sites More sharing options...
