I'm attempting to turbo my N/A ej22, car is a 1999 Legacy L 30th Anniversary edition. I don't see why a phase 2 ej25 head won't mate up with the phase 2 ej22 block and they are both SOHC but I know that there is greater wisdom than I posses lurking in these forums. My ej22 block has single port heads and I want to swap them our for the ej25 duel port heads in order to run boost.
what issues do I face?
will the heads mate right up to the ej22 in a "plug and play" way?
will my stock ECU know what to do with the ej25 cam?
Any general advice?
I will also be switching the full intake manifold so advice on that would be greatly appreciated.
Are there different sensors I need to be aware of?
Line placement issues?
