[SRG]

In 2003, Chrysler came out with the PT Cruiser GT. It had the 220 hp 2.4 L turbo charged engine. In 2004 Chrysler came out with the 180 hp turbo charged 2.4 L engine which was available on non GT (touring and Limited editions???) PT's.

The 180 hp turbos can run on regular gas, as opposed to the Gt's which Chrysler recommends premium fuel. The only difference between the 2 engines is the computer programming.

The 2004 GT's were labeled "High Output"

Good luck with your new GT.
