Not sure about the engine's capability for turbo use, but I would be concerned about factory warranty issues. If you go ahead & bolt one on, then have trans or final drive problems, will the dealer honour the balance of remaining warranty or is the car over the warranty mileage already?

I am almost past my power train warrenty. Traveling sales(what do you do) I read somewhere that the motors will take 6psi and I don't think that the money and work will be worth 6psi.

yeah after talking to some people I think that I will wait untill I have some miles on my car and then do a straight sti swap and go from there. I think that that way I can lesson some of the cost by getting ride of my motor etc.... Thanks for all you help

Every so often, I see someone with a hot scoobie who says they wish they could go rally, but can't because they don't have the money.

For the price of a tidy STI swap and some shiny bits, you can have a stage-ready Production Sport setup. I know which I'd prefer (But I hate Subaru's, so I'm biased )

Heck, even if you just wanted to rallycross or the like (and have a beater with a skidplate and some HotBits on it), you'd at least be able to drive it to work after you hit some big ass rock at Sunday RallyX.

I was in a similar situation when I got my 2004 Naturaly Aspirated Subaru a few years back; as soon as I bought it, I started learning more about subaru, rallying, performance driving, etc and got really interested. It's possibly a sign of my newbiedom at the time that I really wanted more power (insert "tim the tool man taylor" references here;), but I ended up with a similar dillema to yours.
My own opinion after research was that trying to pimp up the power on the NA car wasn't really worth it; I'd spend half the price differential of a WRX, to get a warranty-destroying, questionable-reliability, lower performance hack, while still keeping the brakes, suspension, and all the other RS/TS bits.
At that point I decided to switch to a WRX; 6 months into my financing, it wasn't the smartest financial decision that I've ever done;), but it made me a much happier person than spending thousands of dollars on some bolt-on kits would've.

Few years later yet, and potentially a bit wiser though still dumb as a brick I'll admit, I'm not even sure I needed that much power.  I'm not regretting the switch, but knowing what I know now, I might not have. I know for a fact I cannot myself utilize the full power of WRX properly (let alone the Stage 2 kit that I installed), and I'm honestly doubting I'd be able to push the NA car to the limit the way I know some really good drivers would as well. If I had to do it all again, with the benefits of hindsight, I'd put money into suspension, brakes, durability & protection, classes, practice, and improving my own skills.
At this point I'm not sure I'd even go for an STi swap, unless I got the differentials, transmission, suspension, etc in as well... at which point of course, matters become rather moot as to why not just get an STI

Just my 0.02 cents:)

had some computer issues. Just had a little boy so don't have much time either. i will be at the rallyx in Bancroft on the 26th. I do have a 1997 legacy that I rallyx so that my 09 is only for the road. I am fully aware of the benifits of brakes and suspension(handling upgrades). I am getting Hot bits suspension and have yet to find a big brake kit( aside from the sti brakes$$$$$$) After doing some thinking I don't think that I would fully benifit from sti power. however 170hp just is not enough. I am putting on exhuast and intake, and I found some ohter things that will help. I would like to set the car up to do some track days and solos but it is my daily driver. So I am going to do all the handling things and some hp stuff. I have alot of fun in my rallyx car and it takes money too. Thanks all for you help and input.  

I am aware that it can be fast and 170hp is not bad but I am used to and have driven for some time now cars with more hp and better handling ( after alot of work of course). I have been doing tsd and solos and track days for a few years now and I feel that with my set up handling and hp that I cannot go much faster or push any harder.
