A grand prix gt un-supercharged will smoke a grand am gt, the supercharged gtp grand prix will destroy it.
I have a 2004 Pontiac Grand Prix GTP Comp G Supercharged, and it reccommends premium gas, but it does fine without it.
if you dont know if your grand prix gt is supercharged you should sell it. but if you knew anything about anything then stand outside of your car by either front wheel look on the bottom front of the door and if it says GTP then its supercharged otherwise gt is naturally aspirated.
Assuming you are referring to a stock 2004 Pontiac Grand Prix GT, it does not have a turbo. The GT has a 3800 series V6. You might be thinking of the 2004 GTP or Comp-G models, which have Supercharged versions of the 3800. They only Grand Prix model I can think of that had a factory turbo was a limited edition model in the late '80's. However, I have heard of aftermarket applications available for turbos on the 2004 models.
The Aurora is faster. I have one myself. It has 50 more horses then a Grand Prix GT, and it is also faster then the supercharged Grand Prix GTP. Not much faster, but it is.
No, Supercharged GTP's require a higher flow fuel pump than GT's and SE's.
The GTP is supercharged and the the GT is just the 3800 engine without a supercharger
1999 Grand Prix has 200 HP. A Supercharged GTP has 240. These are both 3800 Series II motors.
My 2004 Grand Prix GT2 runs on 87 octane just fine.
No
The difference in a GT, and GTP is that the GTP is supercharged. Which gives it 40 extra horses over the GT. GT1 means it a car that was realeased in the first half of the year.
A 2004 Grand Prix GT will require approximately 5 quarts of oil. The type of oil required is 5 W 30.
