Although I'm not a fan of these "who can I beat" posts (can't we just all get along), I think I can say something about this, since I own a '94 RT/TT and have an SR I'm working on. I am buliding the SR to be much faster than my TT..so I've done some research.
At 10 PSI, it's not going to happen. The stock turbo'd 3Ss have more power at the wheel than you have at the flywheel at that point, and that's figuring the ~25% AWD loss.
At 15psi your T25 is supposed to making something like 235-250 at the wheels. I believe that's in the 13s..not the 14s. You'd have a chance if you want to boost that high, but it depends on how long of a race. Too short and the AWD will take you, too long and you'll top out at 120 while the mitsus are supposed to go to 155 or somewhere around there.
edit: I totally forgot the weight difference. Yes-3800 vs. 3000 is quite significant..but not significant enough for a 10psi win
