Default 97 impreza wagon 2.2 to 2.5

Disclaimer: I know these threads exist and have researched them all. I am just looking for confirmation before dishing out $1000+ for a new engine.

The story: i have a 97 impreza wagon that had a swapped ej22 engine from a 96 legacy (allegedly). After 2 years of owning it and commuting 80mi a day, the timing belt skipped a few teeth on the crank and now will not run even after fixing the timing. So now i am looking for a new engine And am seriously considering an ej25. I know about their head gasket issues (just did head gasket and clutch on wife's 99 forester) but i really would like that extra 30hp. Especially if its a jdm engine with 50k (again allegedly).

Question to you: will the following engine work for my swap? http://www.sunrisejdmmotors.com/engi...83&page=1&F=ME
Has anyone bought from Sunrise before? Does anyone know of some place closer, cheaper, more reliable? I have heard bad this about Osaka jdm and Tiger jdm engine. Also, can this be done successfully without having a ej25 doner car?

I am located in south east PA. Any info on this will be helpful. Thank you for your time.

Thank you, is the linked (above) engine a phase 1 engine? What is the visual difference between 1 and 2.

Thanks again, this helps greatly.

I believe 96-99 legacy outback's used phase one and on that link it says 96-98 so I think it should be a phase one

That sounds about right, i will call and ask to be sure (if they even know).

Has anyone dealt with Sunrise in the past? Any good or bad experiences?

May I ask why the DOHC 2.5 is necessary?
I'm in the same position - 97 Impreza needs a new engine. I found a 99 Forester (2.5 SOHC) that I'd like to use the engine from. I already have dual-port headers, and can use whatever other parts from the Forester (intake manifold?) that are needed. Is there any other compatibility issue I'm not aware of?

I see. Does that mean the whole wiring harness is different as well, or could the ECU be swapped from the donor car?

Correct wiring is different. Easier to just swap in a stock replacement

The newer Foresters aren't EJ engines.

Phase one dohc engines are found in subies from 96-98 with the 2.5L engine. In 99 they swapped basically everything over to the sohc. Completely different engine

I am not sure if the 2.2L intake will bolt up to the 2.5Ldohc.

However, just get a Ej25D (DOHC) and drop it in with everything. It will run find on the 2.2L ECU. You can use a 98RS ECU if you find one.

Will the 2.5's ECU have any advantages over the 2.2 when running a 2.5 motor?

as far as what i read they will.

cross reference the intake manifold gasket, they should match

I found an EJ25 DOHC complete with everything. How much of everything should really go with it? Mine includes a lot of the wiring, coil pack, injectors, and throttle body. Is everything compatible? I already noticed there are some additional fuel/vacuum rails on the passenger side that my old EJ22 top end does not have at all.
