1197sts Posted January 26, 2012 Share Posted January 26, 2012 How hard is it to swap a EJ22 in place of a EJ25 phase II? I have searched the EJ22 EJ25 swap threads, it seems it is possible but more involved. Anyone have experience with this? Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted January 26, 2012 Share Posted January 26, 2012 This came up recently, apparently 1999+ EJ22 will work, before that will not work in that application. Quote Link to comment Share on other sites More sharing options...

Anyone have experience with this? 99-01 EJ22's are fine. you can not drop in a complete earlier EJ22 and have it be plug and play. different wiring, sensors, etc. Quote Link to comment Share on other sites More sharing options...
WoodsWagon Posted January 26, 2012 Share Posted January 26, 2012 No real reliability advantage in the phase 2 ej22's over phase 2 EJ25's though. I've seen them chuck rods unprovoked. Quote Link to comment Share on other sites More sharing options...
jayg Posted June 8, 2012 Share Posted June 8, 2012 im very close to finish up my swap in my 2000 legacy gt original ej25 to my 1999 ej22 from my impreza wagon i dont have garage or lots of tools and no school ( quit very young ), but from my parking im doing my work... this is my 1st swap and so far every thing is looking good. I rent motor jack but when i was dropping the ej22 in the lecagy i got sick and i was enable to bolt the engine to the tranny one side bolt strait in but the other side it was harder and i was going to be more sick soo i stop there.. (to much work under heavy sun) i will post more sooon as i can p.s sorry for my bad English i hope you ppl can understand me.. Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted June 8, 2012 Share Posted June 8, 2012 i assume the ej25 has a bad bottom end not just bent valves. if it is just valves buy a used good head and put it back together. but for the bottom end, you COULD swap in 96 - 99 ej25 block and use your current heads and intake. but given the history of all ej25s 96 - 04 it may be difficult to find a known good one. good luck.
