HKS has a new clean package for the HKS GT570 which is based on the Nissan GT-R. The previous package was not legal in some places where environmental laws are very strict.

Following some unsavory reaction to the Nissan GT-R-based HKS GT570 Racing Package as far as the eco brigade goes, the tuning firm has responded by releasing an HKS GT570 Sports Package. The previous package wasn't too environmentally-friendly as it was not fitted with catalytic converters. This made it illegal in some countries.

HKS went back to the drawing board and now offers a new kit for the GT570. It consists of stainless steel catalyser midpipes, aluminium intercooler piping, an EVC electronic boost controller and Super SQV blow off valves that come with the piping kit.

The turbo has been fitted with upgraded wastegate actuators and Super Fire Racing M45HL spark plugs are added to the engine. Revised power figures are not available but the Racing Package makes a heady 570PS (419kW) and 540 lb-ft of torque at the wheels. The addition of "road legal" equipment shouldn't make too much of a difference in performance though.

Pricing for the kit is about ¥913,500 (US$9,700) in Japan which is close to ¥315,000 (US$3,300) more than the Racing Package. That's the HKS price for going clean.
