If i decide to swap out a 2.2 sohc for the 2.5 dohc that is in my outback now what will I need? Is it a straight swap, do I use my intake and wiring, etc?

 

Thanks

all of this info is on here. remove EJ25 - install EJ22. no need to swap wiring or intake manifold.

 

here are the simplest directions i can give:

to avoid EGR issues, get an EJ22 with EGR. you can use an EJ22 without EGR if you don't mind bypassing it (it's a POS set up anyway).

get the exhaust headers for an EJ22 unless you use a 1995 then you don't need the headers.

 

the reason the 1995 automatic is desirable is it has an EGR valve and dual port exhaust.

 

you'll swap your EJ25 a/c bracket to the EJ22.

it's easiest to get the EJ22 power steering lines that bolt to the pump to be clean and neat about it, but not entirely necessary.

Don't forget the flexplate is different, you'll want to use the 2.5's. I would check the seperator plate as well, the plastic ones always leak.

I'm actally in the process of doing the same thing. It took me about a day and a half to pull the 2.2 out of my parts car going very slowly to familiarize as I went because this was my first subaru swap. The 2.5 took about a day once I knew what I was doing and once I get home today I'm changing the T-belt, oil seals, water pump, etc., on the 2.2 and If Im lucky have it in tonight. Overall everything was damn near identical when pulling them though.

Good luck with yours when you get to it!
