HKS 93-98 Nissan Silvia S14 / 99-02 S15 Single Port Internal Wastegate Actuator

This HKS single port internal wastegate actuator is built with a robust diaphragm and a precisely calibrated spring. It's designed to manage boost pressure more effectively in your 1993-1998 Nissan Silvia S14 or 1999-2002 S15. By controlling the exhaust gas flow around the turbine, this actuator helps maintain consistent boost levels, which is crucial for optimal turbocharger performance and engine reliability.

The single port design is a key feature, simplifying the plumbing compared to dual port setups. HKS has engineered this actuator to be a direct replacement for the factory unit, ensuring it fits right and functions as intended. The spring rate is carefully chosen to work with the stock turbocharger and common modifications, helping to prevent over-boosting and ensuring the turbo spools up efficiently. This part is a solid option if you're looking to fine-tune your engine's power delivery.

Please note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and any additional hardware that may be required.
