Hello internet, my Outback's EJ25 is a leaky little bastage, and would rather not live with constant worry (and because I'm moving to a completely unfamiliar town in a month and know no one), I am swapping the engine for a EJ22 a friend of mine has rebuilt (he's got several decades and hundreds of rebuilds under his belt). This swap also happens to coincide well with a clutch replacement which I need kind of badly. So here's the question: what, other than the long block of course, do I need? ECU? Intake manifold? Spark plug wires? A life? To get my head outta the sand because I'll be losing 30 hp? (honestly I do a lot of cruising, so I would rather have the economy + reliability)

 

Thank you sirs!

What year is your outback? What year is the 2.2l that was rebuilt?

The EJ25 is from a 98, the EJ22 is from a 95.

Being a 95 2.2, use the whole intake, plug and play....

 

But really, all you need is any 2.2 intake manifold w/injectors, and you can just swap the 2.5 wiring harness and throttle body onto the 2.2 intake.

Thanks!

The EJ22 has EGR, right? Should have a stainless steel 1/2 dia pipe running up from the drivers side head to the intake manifold. If it doesn't, you'll get a Check Engine Light and a code for missing EGR when you plug it in where the 2.5l was.
