Default What to do with blown 01 legacy

So my 01 legacy GT limitied died the other day. engine just shut off, tried to restart and it was knocking like crazy so i had it towed to a shop. shop says the engine is screwed.

quote for a new engine installed is $4300.

what are my options here? what engines will literally drop in and bolt on and plug into the harness without modification? are there places that sell harnesses that will let me drop in other engines? is doing this going to be too much more of a pain in the ass then just letting the shop do it?

keep in mind im in northwestern canada so shipping of engines and stuff can get expensive.

thanks.

the same engine will be the only one to drop in bolt and plug without any modification. you would need to modify your harness to drop in a different engine. if you get the same engine and just swap them out, it wouldnt be to much of a task, being that you are comfortable doing something like that.

ok thanks. i think this is probably what i will end up doing.

That being said, is merging the harness really that difficult? with the amount of knowledge on NASIOC and other subaru forums im sure i can find some sort of an "attach this wire to this wire" guide

also are all the EJ251s the same? Assuming it came from a car with a 4eat?

Default wiring harnesses

You may want to check out iWire. They offer a couple of harnesses. You need to pick the engine and ECU. Then figure out what is needed for your swap. AVCS may or may not be worth the hassle. E85 is another path you could take? Depending upon if it is available in your area.

You can re-use your intake manifold and wiring on any SOHC EJ25 longblock. No hassle.

X2, including 06-11 2.5L, just use the long block, if you don't hook up the VVT (no problem), you will loose a bit of power, not much.

I have an 09 in my 02 Forester, since a year now, I can manually activate the VVT.

What are the complications in going to a DOHC from a SOHC engine. I have found a few EJ25 DOHC motors at reasonable prices so I'd like to use one of them....

Speicifically I want to use a EJ25 DE DOHC motor in my 01 subaru legacy.

No, you don't. It's a worse motor, less power, and blows headgaskets like clockwork. It also has piston slap issues.

If you want to do a turbo swap, you need to rewire the car and swap front crossmembers to clear the up-pipe.

Why not rebuild the engine you have? Unless its really messed up.
If you ever want to get rid of the bad parts I might be interested
