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?

This came up recently, apparently 1999+ EJ22 will work, before that will not work in that application.

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.

No real reliability advantage in the phase 2 ej22's over phase 2 EJ25's though. I've seen them chuck rods unprovoked.

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..

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.
