3Pin Posted January 12, 2018 Share Posted January 12, 2018 I am thinking this should be a clean swap, but just want to confirm as I have never done one. Link to comment Share on other sites More sharing options...
idosubaru Posted January 13, 2018 Share Posted January 13, 2018 Yes the 95 is a dual port exhaust so you’ll need any dual port manifold. 95s can have EGR or not and 98s can have it or not as well, I feel like they usually do have EGR in 98. Any combination can easily be made to work. Link to comment Share on other sites More sharing options...
3Pin Posted January 13, 2018 Author Share Posted January 13, 2018 it looks like the 98 impreza is a 2.5 RS automatic. If I get a 95 2.2 automatic, they should both be egr. Won't the 2.5 have dual port exhaust as well? Link to comment Share on other sites More sharing options...
idosubaru Posted January 13, 2018 Share Posted January 13, 2018 Yes. Only if it’s an RS every other 98 imp is single port EJ22. All of this is answered directly in my swap thread including 98 RS reference 1 Link to comment Share on other sites More sharing options...
john in KY Posted January 13, 2018 Share Posted January 13, 2018 Are 2.2 and 2.5 dual port manifolds the same? Link to comment Share on other sites More sharing options...
idosubaru Posted January 13, 2018 Share Posted January 13, 2018 Are 2.2 and 2.5 dual port manifolds the same? Far as I know, EJ18, EJ25, and 1990-1995 EJ22s are all dual port and swap. Link to comment Share on other sites More sharing options...
