Default STi Turbo Upgrade / Engine Strength?

Anybody know if a turbo upgrade ( I know the turbo is pretty big already) can be done, or if the engine can even handle more boost? How much do you think the 2.5l can handle without internal modification? Is the new 6spd gearbox built better than the WRX 5 spd? I know when you get about 50hp + in mods on the regular WRX the trans can't really handle that much power.

Just a few questions, and I figure since you guys are actually driving an STi, you'd have a pretty good idea.
