Automatic Outback Engine Swap.

Post by rsuazopm »

I just bought a 05 Baja manual with a bad engine. I have a donor outback xt automatic as a donor vehicle. Has anyone ever done a engine swap of this sort? Any advice?

Is your Baja the turbo version already or do you plan to go from NA to turbo?

It's already a turbo.... I know they both have ej255 engines. Also there is differences in the intake manifold and intercooler. my concerns are with the fact that one car is a manual and the other is in automatic. I do not know if that would be an issue when I swept the engines. I'm also a little concerned about connectivity to the ECU. Any information would be a great help!

The long blocks are the same, so if you have any doubts/concerns about interchangeability, just swap complete intake manifolds and sensors, crank sprocket and driver side top cam gear.

I do remember in the 3rd gen legacys, the autos got different timing markers. Well, some early ones did. Later 3rd gens became more standardized. So as a rule, I would swap the complete intake, timing sprockets, and all sensors. Never had any issues or codes.

In your case, I'd just throw the auto engine in there complete and see if any codes come up, then swap the pieces I mentioned as necessary.

Would it make sense to swap the ECU as well if I leave everything on the automatic the same?

No, the auto ecu will freak out if it doesn't detect the auto's TCU. Just run the manual ecu.

I didn't catch that the donor was an outback XT. That's a different generation of electronics, the 4th gens had Canbus.

I'm positive you'll need to swap intake manifolds and all sensors, and the turbo. Unsure about the timing, I suspect that's the same.

I agree. Swap the intake and timing gears with your original engine. Should be straightforward and run without issues.

That is beautiful. I am excited for you. Can you take a picture of the engine bay for us? What intake is on it?

The first picture is the engine bay with everything labeled prior to taking it apart. The second picture is with everything mostly disconnected. I'm hoping to have the engine out by this weekend.ImageImage

Thanks for the pictures. It looks like it is all stock except for the coolant overflow tank, and intake/cold air. Any ideas what happened to the engine?
