i just bought a ej22 engine for 40 bucks on craigslist. im pretty sure it came out of a 1992 legacy will this fit into my 1996 with same wiring and everything? ecm?

Not the same wiring.

You'll need to use the 96 intake manifold and sensors. Easy swap since the wire harnes comes off attached to the manifold.

You may also need to find a dual port exhaust y-pipe. Most 96 had single port heads. The 92 will have dual port.

what he said - bolt 1996 intake and sensors onto 1992 engine.

the 1996 will have single port exhaust heads unless it's an oddball or had already been swapped previously.

 

the good thing is that dual port heads are the easiest to find - pre 1995 EJ22's, all EJ18's, and all Ej25's have dual port heads - so every 4 cylinder EJ engine offered in the 1990's except 1996-1999 EJ22's.
