just bought a 2002 gtp with 76000 miles, was curious on the best parts and what parts to buy to upgrade the performance, are there any modifications that can be made to the supercharger or is there another supercharger you can upgrade to, what would be the best exhaust and headers to get, any other upgrades anyone could suggest any help would be greatly appreciated

Headers- SLP or ZZP
S/C- Not really anything worth mentioning besides porting the inlet and outlet.
Don't think about going with a smaller pulley until you get a scan gauge and see what's going on.

The mod from over yonder
Start with the basics
CAI
Headers or Dp and Plog
Colder tstat 180*f
tunned pcm
then you could probly drop to a 3.5" pulley and change the spark plugs to Autolite 104's
Do basic maintenance first.
Change oil to synthetic
Change supercharger oil with GM supercharger oil
Coolant and tranny flush

I'd say Pulley be the last of the Bolt-On mods.
If I could start over I say...
180*/160* T-Stat
Autolite 104's
CAI/HAI/FWI
U-Bend Delete
Downpipe (3")
Power Log/Headers - I run Pacesetters and I love them
DHP/Overkill/Powertuned or HP Tuned PCM
THEN...drop to a 3.5"/3.4" and if you want to continue modding a say save money and get a MPS System NOW.
Then it is up to you what you want to do with the car. At this point I would say headers (if you haven't done them yet), Ported TB/Ported Supercharger.
Then you might be able to get away with a 3.3"/3.25" pulley with a custom tune.
Afterwards...you can go to either a rockers or a cam. You could also intercool the car and get injectors. If you go that far you'll eventually need a transmission.
Hope this helps ya man.

Every thing in my sig that I did on my Impala would be a great way to start. No engine internals to replace. The last thing I did was the pulley and a tune. The pulley would be the last thing to do until all the other things are done.
