redrocket98 Posted January 27, 2013 Share Posted January 27, 2013 the ej25d manifiold fits with ej22e. this would be the DOHC 2.5's and ej22's with dual ports so i would be good with the ej25 manifold? i would have around 300 in the heads completely rebuilt, another 200 in a ej22 timing kit. and then another 100 or so in head gaskets. then just assembly... sound right? i just dont know if i could pull it off myself, eventhough it would be just pull the heads change the gaskets, put the new heads on and change timing components.

xbeerd Posted January 27, 2013 Share Posted January 27, 2013 i asked this question here... http://www.ultimatesubaru.org/forum/showthread.php?t=137599 and post 2 you can see why youd need the ej22 intake manifold that matches the heads, unless prior to 95 had a different IM?? thats the case with my dual port heads and intake mani's, i have both motors in my garage, the IM will not work.

MilesFox Posted January 27, 2013 Share Posted January 27, 2013 I am mistaken. What i should have posted is that ej25 and 22 harnesses plug in the same. my baad:Flame: Quote Link to comment Share on other sites More sharing options...

LOL. thats true, the wiring is same. hey OP. i just read something from GD about making an intake manifold adapter plate using the IM gaskets as a template taking to a waterjet place. although after going thru all that, you might end up just getting an intake from a JY.

Lehigh Valley Subaru Posted August 7, 2013 Share Posted August 7, 2013 This is the list I have that got my 2.5/2.2 swap running in my 2001 OBW 2.5 block 2.2 heads (dual exhaust ports) Custom intake manifold adapters to mount the 2.5 manifold on the 2.2 heads ($140 at my local machine shop plus some tig welding at home) Depending on your trans/ecu your cams and crank gears will need to be swapped out. there is a huge difference between the two sets 2.2 timing tensioner and belt Quote Link to comment Share on other sites More sharing options...
jboymechanic Posted August 7, 2013 Author Share Posted August 7, 2013 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?

aschwerin Posted December 26, 2016 Share Posted December 26, 2016 I believe I have this car now. Its sat around quite a bit as my '97 2.2L runs smooth as silk. But I'm working on it. Gonna replace the o2 sensor next. Quote Link to comment Share on other sites More sharing options...
