i have questions about my 05 GTP

hello, I just bought a 2005 GTP from a dealership so I don't have a way to contact the old owner.
I noticed the car has a smaller supercharger pulley (I cant remember the size, ill look when I get home), the car might also have a lower temp thermostat since the temp stays pretty low. as far as I know everything else is stock.
from what ive read on this forum I should probably do some supporting mods for detonation reasons.

ive been trying to find headers for my car but im having a hard time finding some for the 2005 model that don't cost a ton. ill do an intake soon as well. what else do you guys recommend so I don't destroy my engine.

the car has 112000 miles, fresh oil, ill be replacing the supercharger oil as soon as I can find some for cheap and I haven't looked at the plugs and wires yet. any help would be great. thanks
 


get a t app or other way to scan for kr.

speed daddy headers work. lately theres been some cross over pipe fitment issues here and there. but for 200 shipped you wont find any cheaper.
 
what do you mean by "t app"?

I was looking at the speed daddy headers but they don't show my year of car. do you think they will still work?
 
Torque Pro for Android is an app then you need an ELM327 from BAFX will pretty much give you the ability to look at all the sensors and allow you to clear trouble codes and even log data. The app is $5 and the device is $21 so it's a really good deal.

Speed daddy headers work fine on 04+. No issues on mine, had them on over a year. No leaks.
 
^This^. Find someone local with a pulley puller and get the 3.8 back on it and go from there.

Don't forget to run premium (91+) in it at all times. And a 3.4 pulley on a stock GTP of that year I'd be careful getting into crazy boost otherwise Chip may visit you.

The pulley is the modular type so I just need to get a stock diameter pulley. What size pulley comes stock on these cars
 


a 3.6 would be safer with a gen 5 blower. and a tune. in car is best. you got locals in your area that tune. depending on what side of Indiana you live in.
 
I'm in southern indiana just over the river from Louisville ky, I think there is a few shops that can tune in the area.
If I go to a 3.6 pulley do you think I'll need a new supercharger belt as well?
