Phase 2 2.5L into an STI swap!
Hey guys, I am a newbie to the forums and was hoping that a few of you could give me some advice and input. I own a car lot and recently purchased an sti at auction that does not have an engine and is also missing the ecu and turbo parts.
Over the years i have compiled a few engines here and there and happen to have a 2.5L engine thats a phase 2 from either a 99 legacy gt or a 2.5 RS. The engine is built, with arias pistons, manly arms, etc. good for 8:1 compression. My hopes were that i could throw this into the STI and get to keep it for myself instead of having to part it out and make some money.
So my question is, will this 2.5 fit into the 2005 sti that i recently purchased? Will it line up right with the stock transmission? Any of the engine accessories need drastic alterations? Any advice would be great.
Im debating on whether or not this is a likely possibilty or am i better off buying an actual sti motor. Hopefully i can use this engine and then buy the turbo components seperately and save myself about 2-2.5 grand and have a built engine in it .
I am guessing the engine will fit, as ive read of people putting sti motors into other subarus, but im just trying to get a feel for what i am getting myself into.
Thanks in advance for any suggestions and advice!

96L Most Over-
From what I've gathered, issues you will run into are the up pipe clearing the corner of the passenger cylinder head and the lack of AVCS function on that phase II SOHC EJ25. Ideally, you'd source a set of STi heads to bolt onto the block and cure those 2 issues in one step.
Mechanically, everything bolts up, use the STi flywheel and clutch. Use the STi intake manifold and engine harness, add a 2nd block vent and drop it in.

no holes to mount coil on plug
no oil return
different pick up pattern on the cam trigger
