More Power for 2.5XT Forester
Okay, I'm new here and this topic may be covered in detail, but I've not been able to find it. I just got a 2.5XT 5 speed. I love it, but wonder where I can go to get some of that "detuned" power out of the motor. I'm thinking a chip or something like that. Can someone point me in the right direction? I live in the Los Angeles area.
Thanks much.

p.s. I owned a Subaru Outback Limited Wagon 5 speed before this one. Loved it, but didn't have enough power. This one is awesome.

my guess is you ought to be able to run 14-15 psi w/ the stock turbo and maybe a piggyback for driveability. if it is the same spec wrx tdo4 that is. other than that a vf23, 30, or 34 would give it some nice topend. I haven't been able to find out the injector size. but they might be the same sti 550's. so you could run quite a bit of boost with those. they are side feed which means there isn't alot available in us yet. a turbo back would give you nice gains and a header as well. I'm pretty sure most gd imreza exhaust bits should bolt right up.I don't see why 400 would be too tough to obtain with mild bolt ons and 20 psi of boost. I think this will be a nice engine to build. but with a bigger turbo you're not gona have that right now power that it has now. that thing pulls hard down low. it just needs more mid and topend.

I'm looking at the numbers and I seriously think they are playing the same game that dodge did with the srt-4. That is one fast car considering it has less hp, only slightly more tq than a WRX, and it has the aerodynamics of a brick. I think they just don't want to upstage thew WRX. I do know they are using pretty close to the same block as in the STI (2.5L displacement, DOHC, AVCS variable valve timing, Semi-closed deck block, Sodium filled valves, Direct Ignition, Iridium Plugs.....) just really detuned.
these are some impressive numbers

The XT also uses a different turbo than the STi. I would treat it as it's own engine and go from there, rather than trying to play catch-up to the USDM STi.
