NEED help setting up EJ25 (2003 Legacy L) Cal Emmisions

Featured Replies

Hi All,

 

I am new to this and need some help from you all. I am not a mechanic and I am in MA.

 

  1. I am getting a 2003 Legacy L 2.5L AWD with no engine in it. I
    was told it had a California Emmisions Engine/ EGR type engine. I have
    my wiring harness present.
  2. The Exhaust from the engine to the part under the front seats
    removed. I will be needing the manifolds all the way to that bolt on
    piece under the car, specifically under the from seats.
  3. Part of the Bell Housing coming off the tranny was broken off where
    the starter in located. I am not sure if the Bell Housing can be
    replace even though I see a few bolts that attach it to the tranny unit.
    I will need some advice on this part. (pic attached)
  4. What engines will fit this vehicle and are there any specific
    things I can look out for? I am trying to make the right choice of parts
    on the get go.
  5. Does anyone have a good used engine or can point me in the right direction for parts for my project.

I HAVE ATTACHED 3 PICS TO HELP EXPLAIN MY LENGTHY WRITE UP.

Thank you all.

Looks like a nice car! Motors from 2000-2004 are options for you. I think 02, 03 and 04 are direct bolt in. There's a little modification required to fit an 00-01 motor but not extensive.

 

Not sure if emissions are a big deal in MA or not, but the car will physically run fine without EGR but will throw a check engine code. There are ways of getting around this.

 

Your exhaust is dual port so any Y pipe from 90-95 legacy/Impreza will match as well as 96-99 with the 2.5 motor and any 2000-2004. You have lots of options for exhaust.

 

You may be able to take some measurements and cut a spacer to put in to mount the starter to the engine. I'm not 100% on how easy swapping a bellhousing is. Someone who's done it before will probably shed some light on that to make it weather proof.
