You have no idea how much I miss my Intrepid's leather seats. I drove my dad's Infiniti to my uncles house on saturday, and I didn't want to get out of the car LOL. I take back what I said about the transmission, they might have equipped the later years (97-03) with 4T65E, not 4T60E, but no matter.
If you REALLY want to see that GT perform on a road course, wait till your mom ain't lookin' and sneak a set of Buick Strut Tower Braces under the hood and in the trunk. The trunk installs in 10 minutes, and ZZP sells brackets for the front. Once you do that, it will put the ES to shame (hides under a rock from the Mopar nuts) lol. These cars aren't cab-forward like the LH's, so the first thing I noticed when I popped my hood for the first time was that I had exposed strut towers lmao.
And you're absolutely right about the tire-squeeling being a bad judge of power. A friend of mine from school has a 1995 Civic, 1.8L 5-speed. He can get the tires to squeel, and he has 17" wheels. When I get my 3100 to sing around a corner, the tires make an irish banshee feel out of practice... it's all in the bald tires hehe.
Yeah 3800's are still peppy. I'm not going to say she tells the truth, but when my sister had her 3800 1997 Regal LS, she said she beat a BMW. If it was a stock 3-series then I can believe it, but otherwise... lol.
To explain why the 3800 out performs the 2.7, and not the 3.2, just remember that horsepower sells cars, and torque wins races. The 2.7 makes the same power as the 3800 (200 HP, using 2003 model year for both engines). However, the 3800 makes an average of 35 more torque, at 225 ft-lbs versus the 190 ft-lbs of the 2.7 (ring any bells, you 3.2L guys?). Even my weak engine makes a little bit more torque than a 2.7 (195 ft-lbs). GM's V6's, even the smaller 60* pushrods are torquey little bastards... mines fun on backyard twisties
When you take the GT out, the only thing you need to be concerned with is the body roll of a 3600 lb sedan. Other than that... have at it!
I also rechecked the GTP... 240 HP and 280 ft-lbs
