Erk.  Hit 'send' too soon.

Anyway, the stock clutch is going to have 
trouble at 15-16 PSI if you intend to launch 
hard, or shift quickly.  You can probably make 
it do, but it's not going to be a happy thing.

I'd want at least an upgraded pressure plate, 
fairly heavy clamping force, at the very least.  
That will provide a reasonable streetable 
clutch, with slightly heavy pedal effort, and 
good clamping.

Personally, though, I think that the upgraded 
turbo at higher boost would warrant a slightly 
less street clutch.  At least that's what I plan 
on when I get my turbo upgraded.
