You should equilibrate under whatever the necessary conditions are, be it high 
pressure or not.  Once the desired parameters have been achieved, then switch to 
NVT.  Since the box is invariant in NVT, you don't have to worry about anything 
expanding.

Please continue to search in the literature for finer methodology points.  I'm 
certain these issues have been addressed in greater detail elsewhere.
