I'm swapping in a 96 ej22 Legacy engine from manual trans car into a 1998 Outback with an ej25 engine with an automatic trans car. I know I need a intake manifold from an automatic, because the intake I have now doesn't have an egr valve and the intake manifold wiring harness has a different configuration. I have a 96 ej22 manifold from automatic trans car  with egr coming from a wrecking yard. Do I use the intake manifold wiring harness from the ej22 automatic with egr or do use the intake manifold wiring harness from the ej25 engine with automatic  that I'm swapping out.

use complete 96 EJ22 intake manifold with wiring harness.

Hi,

Read THIS for the EGR info. Also, you'll need the y-pipe for a SINGLE-port exhaust manifold/header as the 2.5's are all dual-port, and '96-'98 EJ22's are Single.

 

Swap over the 2.5 flex-plate as you'll need it for the AT's torque converter. Reseal the rear separator plate if @ all leaking. ....don't touch the rear main seal unless you're sure it's leaking and read up on here about caveats if you do change it.

 

And as noted above just use the '96's AT, EGR-equipped IM.

Does anyone know if the intake manifold wiring harness for manual trans. and automatic trans, cars are the same for 1996 thru 1998 2.2 and 2.5 engines. Need to know for two projects I have. They are  a 1998 and a 1999 Outback   2.2 sohc into 2.5 dohc car engine swaps. The person who was helping me on several previous successful swaps of 2.2 to 2.5 cars has gone "missing". To further confuse the situation I still have two of the Legacies with manual trans. Both cars have a 2.2 with egr. in them. One car has egr in tack and the other one has egr pipe cut and sealed shut and it looks like the egr port in drivers side head has been plugged.

 

So basically I'm finishing up someone else's work. I also have a lot of 2.5 dohc manifolds and wiring harnesses left over from the successful swaps done over the last two years.
