Adding more horsepower to the new Toyota GR Supra has never been easier, with the new AMS Performance A90 2020 Toyota GR Supra Alpha 8 GTX3582 GEN II Turbo Kit. Our team has engineered and built the 2020 GR Supra platform’s first publicly available internally gated full turbo kit that utilizes the OEM electronic wastegate. This unique advancement allows for a seamless integration of the OEM ECU for boost control the way it was intended from the factory. The GR Supra’s electronic wastegate system particularly excels at boost response over mechanical alternatives, making it the ultimate choice for part throttle drivability or on-off throttle situations as seen on a road course.
