2.5rs motor swap to replace 2.2

[azlegacy]

Will a 2000 2.5rs swap right in place of the current 2.2 or do I need the whole whole wiring harness from the 2.5rs ? I know ill need the ecu as well .

(taken from Engine swap questions READ HERE FIRST (https://sl-i.net/FORUM/viewtopic.php?f=31&t=3347))

"Any EJ series engine will bolt to any EJ series transmission, and any EJ series drivetrain will fit into any car that had an EJ series drivetrain in it before. This pretty much means that if you have a post 1990 4 cylinder in there now, you can put any other post 1990 4 cylinder in. "

BUT

"With subarus, you will have to splice the two harnesses together at some point along the way, whether its in the dash or right after the ECU."

hope that this helps!

I can't remember, is the 00' MAF or MAP based? I put and 01' RS motor in my 98' LGT and I had to do a little work to make the MAF harness work on the MAP intake. I also had to build a semi-custom IAC setup

I ended up having the 2.2 refreshed.
