Product Details

If you're looking to significantly increase the power output of your performance vehicle, a high-performance turbocharger like the HKS GTIII-5R is a critical component. This turbocharger is designed for enthusiasts who demand serious power gains and are building a custom forced induction setup. It's a well-built unit that represents a substantial upgrade over stock or smaller aftermarket turbos, capable of supporting high horsepower targets.

The GTIII-5R features a robust A/R 1.00 housing, which is optimized for airflow and performance in the mid to high RPM range, helping to reduce lag compared to larger housings while still allowing for significant top-end power. The wastegate (WG) is integrated, simplifying installation and ensuring precise boost control. HKS is known for its precision manufacturing, and this turbocharger is no exception, built with durable materials to withstand the extreme conditions of high-performance engines. This unit is ideal for those building a dedicated track car or a street machine where maximum power is the primary goal.

When installing a turbocharger of this caliber, it's essential to ensure all supporting modifications are in place. This includes proper fuel system upgrades, engine management tuning, and potentially upgraded cooling systems to handle the increased heat and stress. Because this turbocharger is not CARB approved, it cannot be shipped to California. Always consult with a professional installer or tuner to ensure your build is safe and optimized.
