It would be good to know how much it can take?
Also is there any inherent weaknesses that can be eliminated to allow higher boosts, such as forged pistons, different crank, special rods?

Also, the turbo won't self destruct, it'll just tear the engine apart. As for higher boost applications, Garm is running 24 psi with the mods previously mentioned, as well as a few others (block bored/sleeved/notced,standalone, fuel pump/rail, P&P'd head, etc.) If you have not already heard, tuning will be an issue at higher levels.
