Welcome. I've been told the only difference between the two is software and that means pcm. There is no way you could run a GT (turbo) pcm on a base PT. I don't know how you would get the software loaded on to a base pcm. Maybe somebody who knows more will say different. Anyways, welcome to the forum. My first PT was an auto '01 base model with the F package. My wife took it over when I got the '03 GT. I still love to drive the '01.
