HKS USA just announced that they will have a Hyundai Genesis Coupe ready for the Sema show that will be held in November. The car is set to be released in the spring of 2009, but Hyundai already let HKS USA have a go at it. According to their press release, HKS will upgrade the engine with a GT Turbo, new internals, exhaust system, intake and a HKS engine management. Although no power figures are yet released, I'm sure it will be enough to hold its own on the track.
Other improvements are in the suspension department and the exterior of the car. HKS will replace the suspension with their race proven Hipermax III system. The exterior will be enhanced by Ken-Style, these guys also make the aero parts for the HKS Time Attack cars.
