Who ever wrote the second comment on this is a fool. only 97+ Grand prix GTP's have superchargers. Nothing before then.

I drive a 1998 Grand Prix GTP and the only person that has been able to beat me is a Corvette with a 427 big block, so I agree with the first guy. They are the best and fastest American cars!

First off, as early as 1991, Pontiac was putting turbos in their Grand Prixs.
Second, ALL GTPs or STE are turbos, while a few GTPs received the supercharger. And in 1995, Pontiac dropped the supercharger in ALL 3.4L GTPs. Here's one site to back this up. I can't find the other, but it is true. The owner is correct.

Here's a correction for all the wrong comments, 1989-1990 there were a few turbo 3.1 grand prix's, the only STE's that were turbo were some of the 1990 year models (first year for any 4-door W-body), 1991, GM created the 3.4 DOHC V6 for the Lumina Z34, Grand Prix GTP, and Cutlass Supreme. In it's run from 91-97, the 3.4 DOHC was never offered with turbo or supercharging. Since the 1989-90 Turbo grand prix, there was no form of turbo W-Body car until the 1997 Grand Prix GTP/97 Buick Regal GS.

I cannot speak to '95 or earlier, but I happen to be in the process of buying a 1996 Grand Prix GTP which has a Supercharger. So Most of the earlier comments on that subject are incorrect. While I do not yet own this car, I have known the person who owns it since he bought it, so I am certain of the details of the car. It is a 1996 GTP with a 3.8L Supercharged engine. (It also has upgraded front discs, beefier sway bars, stiffer springs, and a smaller supercharger pulley to make it spin faster)

I have no clue as to where everyone is getting this info on 95 and 96 GP GTP's. But seriously everyone needs to get it right. I am a GM certified technician, have been for a while. And they have never had 96 GTP's with 3.4s to have the supercharger. Bonnevilles and a few Buick models had the 3800 supercharger, but not a 3.4. GM has never had a 3.4 that was supercharged or turbocharged.
I have two 1996 Grand Prix; one is an SE Coupe with a 3.1 and the other is a GTP with a 3.4. A 1997 Grand Prix can have a build date of up to five months before 1997, which could make it seem like it's a 1996, but it isn't. People need to check their titles. But Grand Prix are great cars; don't get rid of them.
