So I just got a new group but I got the wrong BB size.
175mm 156 Q factor BB30

$200 shipped. These are in near perfect condition with less then 150mi
Just need to replace with GXP is all

You can run a BB30 crankset on a frame with BSA.
raceface and Rotobikes make BB's for that:

EDIT: NEVER MIND, you said GXP not BSA. sorry.
