Similarities and Diiferences of the 2.5 RS and the 2.2 OBS
As you can tell, I'm very new to this. So bear with me. 
I have a 2000 OBS for 3 years now. All I have are nice rims on it. But now I'm looking to start finally moding since i'll be graduating shortly and will no longer be a poor college boy. (yay) I know pretty much all exterior stuff works for both cars, but there is not much stuff about my 2.2L engine. So what parts (general stuff) will work for my Scooby that works for the 2.5 RS? Anything you can think of will help, cause I plan (eventually) on doing all that I can to it.

If it were a 2.2L, all suspension components would be interchangeable. I would assume you could put an RS suspension on an OBS also, but I'm not sure. I think Borla used to make headders for the 2.2, but I'm not sure if they're still for sale. I believe there are several options for exhausts. ISR used to sell a lot of offroad sorta stuff (like lfit kits). Depends on what your using the OBS for. Maybe the Ganzflow intake will fit on a 2.2 (or Larry makes one for the 2.2?). Since the WRX release, all us old-schoolers get pushed to the bottom of the heap.
borla does make headers for the 2.2L, also, basically any bolt on part that works on the 2.5 works on the 2.2, i have a 2.2 impreza with
k&n intake
borla cat-back
lightweight crank pulley
whiteline rear swaybar 18mm-22mm
front strut bar
ACT clutch
tein flex coilovers
all made for a 2.5

So basically, everything SHOULD work for both cars (besides the obvious spoiler and the Internals of the engine like the rods and such)? That would sure make searching around much easier. does this mean things like Air flow and intake are pretty much the same? I suppose the only thing different would be the amount of feul to fill the more displacement for the same effort with the same air flow...or am I missing something? Sorry about the zillion and one Questions.

BTW I plan on making my car a street car. I've been offroading it here and there, so now it's time to replace(and upgrade) the many-a-dented parts under the car (I've already started with the rims, and now i'll need a new Exaust, header, and front bumper for sure)!
I really want to Turbo this sucker too. So i'm doing a lot of research on that stuff right now. But that's more q's for the other threads.

yeah, most everything bolts up, suspension, exhaust, high flow cat, intake, pulleys...the only thing that wont is a header, 2.2s have a single port(after like 98 or something, but thats another thread all together) 2.5s have a duel port, so a header needs to be made for the 2.2, but borla has a nice one, even with the stock exhaust/cats, it has a very nice grumble to it
ive also been doing research on turboing the 2.2, from what i have seen, you can do it with the kits for the 2.5, you may need new heads though, which is good, cause if you put the 2.5L duel cam heads on it will drop compression and allow higher boost. i think, or i may be talking out my ***

borla does make headers to fit the single port 2.2 but you can swap the heads with cobb heads if you go turbo because they should flow so much more(at least looking at them on there web site) www.cobbtuning.com

Wow, do you mean swapping the 2.2 heads out for the 2.5? Looking at that (really awesome) website, it never said anything about 2.2L, so this is why I'm assuming you mean to change the cams and stuff to 2.5L.
Is that really Possible (or should i say, plausable)?

CR is not lowered that much if at all because 98 DOHC heads are 9.7:1 and newer SOHC are 10:1 the same as the 2.2(i think thoughs numbers are right but will not be lower than 9.5:1)
as for compatablility of parts on the headers the cams might be the same(have not looked in to this I was planing to buy Cobb cams) everything else should be the same but i might be wrong on that so ask someone that has done this swap or has more knowledge than me
hope I could help

Guys, it makes more sense, and will be more reliable, to swap in a whole engine than just swap heads. More often than not there are oil or water jackets that don't line up properly. If you really want to know for sure what works and what doesn't, contact CCR in Colorado. They are all-knowing when it comes to OE Subaru engine parts.
