i just had a chat with mechanic form near where i work and he told me that i should just swap the ej22 straight into the forester but put the ej20 injectors on the ej22 seeing as i am going to try running it on the ej20 ecu

Hey guys i'm relatively new to subaru's so i don't know much about them at the moment so i was wondering if you guys could enlighten me on a few details. And yes i have searched through the forums and google but i can't seem to find much info on anyone swapping from a ej20 to a phase 1 ej22. Everywhere i could find was about people swapping out a ej25 to 22. I was wondering what i would need to replace/ modify to get the ej22 into the 2000 forester(manual) I am using the ej22 as it was the engine in my last car which i still have but with a blown head gasket and 350 thousand km's (doesn't blow smoke just compression gasses going into the cooling system atm) and I want to pull the engine out of the car and replace the head gasket with a thinner one, pulley's with light weight ones, maybe a lightweight flywheel. Maybe even cams, Pistons and conrods depending if i can get the money when i start putting the engine back together By the way the ej22 is out of my 1991 FWD Liberty LX (auto) or Legacy everywhere else P.S I apologise for the somewhat disjointed post as it's quite late for me in sydney
