  1. So you swapped the 2.2 heads onto a 2001 SOHC 2.5?  Why?  I put 2.2 heads on a DOHC 2.5 to get away from the "troublesome" DOHC heads and head gaskets and for more power in my Legacy that originally had a 2.2.  Are you doing this purely to gain compression?

  2. New struts, Baja springs and Subtle Solutions 1" aluminum spacers on all four corners of my 2003 Outback.  Also added new tires and a set of White Line camber bushings so the rear tires could be kept within factory alignment specs.  New front axles and a four wheel alignment.  Gained about 2.5 inches of ride height all around and still have perfect alignment.  Rides and handles great too, really happy with the setup.

  3. You don't need to drill the heads, just the head gaskets. I don't have any pictures to offer. I would buy a set of 2.2 head gaskets and use them as a template, you will see immediately where additional water passages will be needed. It sounds crude, but have confidence, it will work. I have 12,500 miles on mine so far and the short block had 175,000 and the heads had 201,000 miles on them when I mated them together.

  4. You have to use the intake that matches the heads, so 2.2 heads and intake.

     

    A stock 2.2 timing belt kit will work, but you have to cut a small timing cover mount boss off the 2.5 block for it to fit. Very easy, it will be obvious when you're ready to install the timing kit.

     

    You must use the 2.5 head gaskets, get them from a Subaru dealer or get the updated Felpro three layer metal gaskets. You will have to drill additional water passages, helpful if you can lay a set of 2.2 head gaskets over them so you can match up the water passage openings.

     

    You have to pay attention to what heads you get. You'll need 1995 2.2 heads for the exhaust ports to match up, but depending on which transmission you have you may or may not have EGR. The donor will have to match.
