Right due to a certain ingress of water in to my engine - 2.0l EJ20 (legacy phase 1 1989 - 94?) it requires replacement. I have a option of a 2.2l EJ22 from an early 2000's car. I believe this is a semi open deck block as opposed to the CDB however it will be NA and im not looking for stupid BHP.

Does anyone know if I will be able to use the original ECU from the EJ20 block (with a remap).

Also is the exhaust outlets / Manifold the same so I can use my existing exhaust with minimal modification.

Are there any other major differences that are going to cause me issues? Bare in mind the engine is no longer in a subaru so its just the engine without power steering pumps / AC pump etc.

Any help appreciated. Ta.
