Product Description

The Turbosmart TS-0615-6142 Wastegate Actuator is a performance-oriented internal wastegate actuator engineered for the 1989-2002 Nissan Skyline GT-R equipped with the RB26DETT engine. Designed to replace standard actuators when running upgraded turbochargers (such as Garrett or HKS bolt-on units), this IWG75 actuator offers more precise and stable boost control, especially at elevated boost levels. With its large diaphragm and robust construction, it expands tuning flexibility and delivers a broader, more responsive boost curve compared to stock units.

Constructed with a billet aluminum housing and a proprietary silicone Nomex diaphragm, the TS-0615-6142 is built to endure the demanding conditions of high-performance turbo setups. The pre-set 14 PSI spring provides a solid base for increased boost targets, while the stainless steel rod and locking collar system allow for future spring swaps if your tuning goals evolve. This actuator is ideal for enthusiasts and tuners looking to improve throttle response, consistency, and overall turbo behavior in high-boost applications. Professional installation and boost tuning are recommended to achieve optimal results.
