When you say "whole PI swap", does that mean heads, cams, intake? Or does it mean PI motor? I ask because the PI heads with NPI pistons raise the compression to a point where boost is not safe without forged internals.
If you have the whole PI motor (or if you are extremely brave with the PI heads/NPI pistons), this kit will allow you to put a Cobra blower (Eaton M112) on the PI heads. Terminator Intercooled Kit for the '99-04 GT

Nope. Cobra heads are completely different than 2V heads so the intake won't fit. There are plenty of blowers for 2V motors though.
Increasing the compression on a blown motor in no way requires forged internals. You only need forged internals when you get past about 450 rwhp.
However, raising the compression on a blown motor will require less spark advance, less boost, and/or more octane to stay out of the knock.
Let an engine knock and it will get destroyed just the same weather you have forged internals or not. The rings will let go in either case.
EDIT: Oh, and that cobra blower and intake manifold wont work on your PI heads unless you get a PI intake that accepts the eaton like the tork tech mentioned above.

Yea, you obviously know a lot more about this than I do. Main point of mine: lots of boost + high compression = no go (usually). And I've been told that positive displacement superchargers (like the Eaton mentioned) is much worse for pinging/detonating with high compression because of the amount of boost it makes low in the RPM band.
Yeah... it will be difficult to tune with any kind of real boost on pump gas at 10:1 or more static compression. My point was just that forged pistons wont help unless they are dished to reduce the static compression ratio. I would imaging that about 8-10 psi would be fine with about 10-10.5:1 cr. Beyond that may require something more than pump gas.
Although, I've heard 4v engines tolerate boost and compression better than the 2v engines. Something to do with the combustion chamber being symetrical with the plug in the center.
honestly
by the time you buy the whole set up to put a cobra blower on your gt, you could have bought a much better set up for equal or less. you want a supercharger setup? the do NOT buy a "kit", they screw you on that just cause it's a "kit"....if you wanna save a lot of money then do this $1500 96-04GT Supercharger kit "how its done" - MustangForums.com
