The Porsche 911 GT2 Evo represented the top specification ever produced for any air-cooled Porsche. Designed to compete in FIA GT1, it incorporated a twin turbocharged 3.6L flat-6 engine rated at a full 600 HP and 490 lb-ft of torque. As compared to the Standard 993 GT2, Porsche widened the rear fender extensions to cover wider modular wheels and added a new front spoiler with inlets for oil and brake cooling. A second deck appeared on the already outlandish rear spoiler, which could be mounted higher in the air stream for added downforce. Approximately 11 examples were produced.
