  1. General Troubleshooting and Technical Help
    1999 Forester S 200,000 miles ej25. First Subaru. Car drives fine but idles terrible. Shaking misfire idle. I’ve been chasing the misfire for a bit now. CEL will say p0304. Compression test comes back 60ish psi. Leak down test has air leaking from exhaust. Timing is perfect. Belt is newish. So...
  2. EJ25 - 2.5L Non-Turbo (1998-2010)
    I recently got a 2006 Forester Base with 5spd, because I missed having an older Forester, but also it was my late mother’s and I wanted to keep it within the family. It has 163,000 miles, pretty well-maintained. Recently had the water pump and timing belt w/ tensioner done at 130k, oil changed...
  3. Motor Conversions
    Hello folks, I have a 2001 forester with a ej25 n/a motor and automatic transmission. I am going to be using a donor engine from a 2000 legacy but with a manual transmission. I am only swapping the motor but it does seem there are some things that will need to be swapped out. Can someone please...

  6. Transmission and Driveline
    I have a 2002 Subaru Forester that I just put a brand new engine in over 8 thousand miles ago. It has 228k on it. Since then it’s been a great car, besides the fact that the transmission acts up sometimes, and tonight it left me alongside the road. After going up a steep hill (55-60 MPH), and...

    I was wanting to put a turbo in my 02 Forester (ej25) but I've heard they don't handle boost very well. So I was wondering if it's possible and what I would need to put a wrx engine from the same year in it.
  8. EJ25 - 2.5L Non-Turbo (1998-2010)
    Hello all, I am in need of some advice (obviously), my foz is about to roll over 324,000 and I'm about to do the head gaskets. I bought the car a couple of years ago for $200 at about 300,000 miles. It was a steal! Needed a new alternator so I slapped a spare one I had on it and drove it home...
  9. EJ25 - 2.5L Non-Turbo (1998-2010)
    Long story short, I had the passenger side timing gear sprocket break off the camshaft while driving on the highway. Car was towed home obviously after that. (Link to that discussion and thread right here) After 5 months of pulling the engine and pretty much rebuilding the entire engine...
  10. EJ25 - 2.5L Non-Turbo (1998-2010)
    Here's a real quick background from this first time poster. I bought my teenage daughter a 2010 Forester 2.5X Limited (non-aspirated) as a repaired salvage title vehicle (this was my first Subaru) a little over a year ago. The vehicle ran and drove well upon before and after purchase. It...

    so i'm swapping in an ej20 for my ej25 (both turbo if that makes a difference), and i've gotten everything connected and all good. i ran over everything with a sensor and it does not detect the cam sensors. i am using the american cam sensors but they are noticeably shorter than the japanese cam...
  12. Motor Conversions
    Ok so first post, tell me if I'm doing it wrong. My 2004 fozz got a knock so my fiance and I decided to swap the engine to a 99 ej25 we found online. The "new" 99 engine was running when it was pulled. We successfully got the donor into the car but are having issues getting her to start. From...
