[EJ25 doesn't run well after engine swap]

i removed the exhaust (at the exhaust manifold) and unplugged the O2 sensors and it ran exactly the same as it did before. so the exhaust and O2 sensors shouldnt' be the problem.

 

i used a 97 GT intake manifold in a 98 GT vehicle. slight vacuum line differences and the 97 had the charcoal canister lines that the 98 did not have. it all seemed to go together right, but i'm hoping the problem is there since that's easy enough to do. so i'm swapping manifolds right now so it has the stock 98 GT set up on it.

 

Did you hook up the fuel lines backwards. You can swap the pressure and return lines without realizing it.

[Really getting pissed at these 2.5's]

I've got 2 apart on my garage floor, a 97 DOHC EJ25 out of an outback, and a SOHC EJ25 out of a forrester.

 

The DOHC has badly rusted and pitted cyl walls, the SOHC had a piston that blew the ringlands off. AND, previously unknown, it has huge gouges in one cyl wall. Like gouges you can feel through the paper towl you're using to wipe down the cyl's with ATF.

 

No big deal I think, I'll use one half of each block and see how it goes. Then I get bit by the thrust bearings, one is on the third main, the other is on the rear main.

 

How many POS EJ25's does it take to build one good one?

 

I've got a sea of EJ22 + EJ25 parts

 

I'll see about collecting another EJ25. There's enough with blown headgaskets kicking around.

 

You definitely can't use one half of each block unless you have them line bored. The block halves are mated to each other and machined together.

[Installing a 4EAT in a 98 Outback]

Thanks for responding, I appreciate it. They look identical, range switch is different but can be swapped. I think I may have the trans ECU also, I'll have to look. Ripped a bunch of stuff off of the car before it went to the crusher. Poor car been off the road since 2003, hated to see it sitting there rotting. Anyways, I anxious to find out how it runs with the 4.11s in it too, should be similar as the 5 speed has 4.11 gears in it.

[Installing a 4EAT in a 98 Outback]

I have my 98 Outback with a bad trans, fluid is burnt to a crisp, I have a good trans out of a 95 Legacy with the rearend to go with, what I am wondering is are they the same except for sensors maybe?
