Peter Nam's atelier remasters one car and one car only, the air-cooled Porsche 993, to bare metal and back with a full carbon body. Coupe started it in 2017 at 430 hp; GWR revs a naturally aspirated 4.0 to 9,000 rpm for 500+ hp; Turbo and the 1,000 hp Slantnose F-26 take the twin-turbo route; GXR-Evo is the 455 hp track weapon at 2,386 lb. Every program is capped, most under 40 cars.
