October 18, 201510 yr i have this 2000 impreza 2.2 5 speed i was going to fix but i think it may be too rusty, soooooooo i found a 2000 OBW 2.5 5 speed w/ a bad motor and i was thinking to use the 2.2. i read this will work....then i read it won't work....then it would work... will it work and anything i need to be aware of other than swapping the driver side sprockets? thx g Edited October 18, 201510 yr by hogweed
October 18, 201510 yr should work fine... 2.2 is single port so you will need the y pipe for that engine
October 18, 201510 yr Mechanically it installs and runs and drives perfectly. That EJ22 with exhaust manifold bolts up and plugs in to that EJ25 vehicle. If the EJ22 has no EGR and the vehicle it's going into does have EGR: then you'll get a check engine light. If that's a problem for you or you can't work around it then no it won't work. Options:1. ignore the check engine light 2. install the EGR equipped Ej25 manifold onto the EJ22 and play with vacuum hoses to get the check engine light to disappear. 3. bolt the EJ25 heads to the Ej22 block to retain fully functioning EGR.
