EJ25 Phase I and Phase II swap info request

Ok everyone, so I have quite a question here. Basically, I have a rebuilt Phase I EJ25 with about 2k miles on it out of a 96 outback that I am curious about swapping into a 2000 Outback with a Phase II EJ25...
Is this possible?
If so, is it a straight forward swap? wiring harness? etc?
I have the motor just sitting around and I found a killer deal on a 2000 Outback limited that needs a new engine.
What do you guys think?
Thank you in advance!

pretty straight forwad swap. keep the stock wirring. cam trigger timing on the phase1 dohc 2.5 and phase2 sohc 2.5 is the same

sweet...so keep the stock wiring and it should slide in easy as pie?
it doesn't matter if one or the other is dohc or sohc? they are interchangeable?

No offense, but unless Subar-styles has done this himself, go check out the Ultimatesubaru.org site on this swap.
Phase1>>Phase 2 does have some gotchas - some may be 'show stoppers'. Plus I believe the '00 is MAP-based - not MAF....MAF is same as Legacy's from '90-99>>
Wikipedia Link.
You 'could' put the heads from the phase 2 on your phase 1 block, keep the phase2 IM and wiring and you'd be good to go.
Do some more research.....

i would expect just fabbing the stock sohc manifolds's sensors/wirring to the ej25d manifold would be the easyiest way. as per not having to swap heads.
