Looking for T25 numbers.
Planning out my DIY turbo setup around a T25 setup. I'm shooting for anywhere from 200 to 220rwhp, obviously with a preference towards 220. I'm going with a T25 because, for now, I'll be happy with 220rwhp. (power/weight ratios shows my car will keep up with an STi at 170rwhp, so I think 220 will suit my fancy. )
I'm having a hard time finding dyno numbers and graphs for the T25 .48 A/R, though. If I'm not looking hard enough, please link me (or tell me where to look). If you have a setup like this, post it up and tell me how soon you're spooling the turbo and how much power you're making. If I can hit 220rwhp on 12psi, I'll be a happy camper. I'm planning on starting with a new BEGi manifold and DP, but the rest of the kit is up in the air right now.

You should be real with yourself and understand that 200whp isn't going to be enough. There is never enough, and with a T2 footprint, you are going to be leaving yourself only a few expensive options for turbo upgrade down the road. If you go with something that has a T3 footprint, you have many more options and a much larger region for upgrade when you decide to do so. Just throwing it out there for ya, if not good luck with the T25.

Savington, I've been saying it for about 3 weeks now, but the holidays and my injector issue got in the way. I'll be taking my car to the dyno late next week after my 305's get back from the cleaners. I expect (with the setup in my sig) that I should be able to achieve 200rwhp at 10psi. I've been having a boost overshoot problem that I expect to be able to solve with a helper spring. We'll see if 12psi is possible but I won't sacrifice A/F's to do it.
Here's a link to my build thread, it will walk you through every part on the car, why, theory, price, engineering, everything:
