We had the pleasure of working on Jason’s white GT-R. It was a very involving build process with work done to both the engine and the transmission. Jason’s car features our SPE Stage 3, but instead of utilizing the Greddy turbo kit, Jason opted for the HKS GT800. This is SP Engineering’s first time incorporating the HKS GT800 into one of our builds. The HKS GT800 is one of the best kits for those who are seeking all around response up to 900 awhp. The HKS GT800 kit shares the same low end response as the HKS GT570 in our SPE750 kit, but has much more capable upper end power. Therefore, no sacrifices are made throughout the entire RPM range.


To match the increased performance, we performed the SPE Stage 1 Transmission upgrade. This would increase the tolerance of abuse from the power that the engine is making now.

On 104 Sunaco and 1.8 bar, the car put down 829 AWHP and 764 ft-lbs. During the tuning sessions, the roar of the car echoed throughout the entire shop. The sound is nothing short of amazing. The car pulls relentlessly and is amazingly quick.
