88HatchMonster Posted August 16, 2005 Share Posted August 16, 2005 Hi, I have two EA81 hatches and I'm going to be getting a free 94 impreza soon with (I'm guessing) an EJ18 in it. My question is: If I go throught the whole process of swapping the EJ18 into one of my hatches, at a later time would I be able to just swap in an EJ22 long block? Would I be able to use the same manifolds and wiring harness etc.? Would I just have to swap in the EJ22 computer? Thanks Quote Link to comment Share on other sites More sharing options...
redwagon Posted August 17, 2005 Share Posted August 17, 2005 The injector and ignitor plugs might be different, but it's easy to splice them. Depending on year and whether your engine is AT or MT, the ignition plate behind the crank pulley may be different, but they swap straight over. You can run the EJ22 just fine off the EJ18 ECU. There's lots of info on this swap over at both nabisco and i-club. Quote Link to comment Share on other sites More sharing options...
