Changing 2.5 DOHC for 2.2 DOHC engine in 1999 Subaru Outback

[catsdaddio123]

  My mechanic is changing my 2.2 engine in my 1999 Legacy Outback for a 1999 2.2 engine but we have encountered a problem. At first we had fire to only two cylinders. Then we changed to a 2.2 coil and had no fire at all! Do we need to change the computer? This job is almost finished but we need help!

ah ha - more information than the previous post a 99 EJ22 is the problem.

 

the 99 EJ22 is not a plug and play swap.  a 1998 or earlier EJ22 would plug right in and run.

 

i assume he had to swap the EJ25 engine wiring harness onto the EJ22 intake manifold?  or did he try something else...cut/splice anything?

 

i'm not sure the simplest way to remedy this off the top of my head.

 

the Phase II EJ22 may have the wrong cam timing triggers - so you'll need Phase I DRIVERS side cam sprocket and crank sprocket. you might be able to install the EJ25 sprocket onto the Ej22 - I'm not sure if you can just bolt those on and go or not though...i assume it's possible, i know you can with later models swap those parts.  the crank sprocket will install just fine.

 

sure fire way is to bolt the EJ25 heads to the EJ22 block and then use all the original EJ25 intake, sensors, cams, etc...but you wo'nt be wanting to do that.

probably a typo, but part of this is wrong.

there is no ej22 DOHC engine.

 

 

is changing my 2.2 engine in my 1999 Legacy Outback for a 1999 2.2 engine

again , a typo?

but this makes no sense either.

 

but if you are using the 99 ej22 engine to go into a 99 outback, you are going to have issues.

he chose the wrong year ej22.

 

you want an ej22 from 95 - 98 w/EGR.

either swap one of those in,

 

or swap in the heads , intake, crank sprocket, and cam sprockets from a 95 - 98 ej22 with EGR onto the block you have.

 

but if you want to try and make it work, try gary's suggestions.
