Default EJ25 ECM source

Hi gang,
I'm new to this group and also new to Subaru engines. About a month ago I got a EJ25 with the electric throttle body with only 600 miles on it. I need to get a stock ECU for it and the wiring. I'm putting it in a kit car. Could anyone point me in a direction as to where I can get a ECU that will match my engine and get me on the road? Thank you.
Jeff

Do you have any idea which car and what year it came from? They vary a lot!

If you've got an '00 or '01, I have an ECU, intake manifold harness, and the chassis portion of the engine harness available...

Both of you should have noticed that he said "electric throttle body."

The engine is an 2005 or 2006. I have a lot of numbers/ letters on the engine but the guys at the local Subie shops can't ID it from them.

Not to hijack your thread, but how much would a used SOHC 2.5 run? I have a 99 Forester and would just like to know in case I ever need a long block.

BTW JiI, welcome to subies! The 2.5 is a good engine, I've got 113k on mine, run it hard, and it's never let me down. I absolutely love it, good torque for a NA (naturally aspirated) 4 banger. If you've got the chance, why not spend several hundred dollars and add some Delta cams and headers? If I ever need to have the engine out, I hope to have the money to do a few upgrades like that myself.

I got lucky and got mine for what many pay for one with 30,000 miles on theirs. I've seen $800-$4,000 for a EJ25 depending on mods, how it was used, miles etc... If you can get a low-mileage one for under 2 grand, you're doing pretty good.

I saw that and since the guy clearly wasn't sure of what he had, I put it out there. Some people who don't know much about these engines might consider the IAC and TPS to be part of an "electronic throttle body". Thanks for playing...

I'd post a picture of the throttle body if I knew how to do it on this site.

For pictures, you have to post elsewhere (like photobucket) and link to them. There's a thread on it.

+1. If he said "fly by wire" or something, that assumption wouldn't have to be made. Not his error, but it did leave it open.

The simple tell is does it have the mounting for a cable to pull open the throttle plate or not? If there are no semi-circular brass cable mounts, it's drive by wire...

Yeah, fly by wire. Subaru.com just let me know that it's either a 2005 or 2006. I'm guessing 2006 due to the low milage. Got a lead on the ECM for $165 and now I just need to get the wiring! (And a tranny adapter and a tranny and some tubing to hold it in the frame and....) The list goes on...
