The Nissan RB26DETT is legendary for its performance potential, and maximizing that capability requires precise boost control. The Turbosmart IWG75 Internal Twin Port Wastegate Kit, part number TS-0615-6142, is engineered specifically for bolt-on upgraded Garrett and HKS turbos that retain the stock turbo location. Designed as a high-performance upgrade, this actuator delivers the same motorsport-proven technology found in Turbosmart’s renowned external wastegates, now adapted for internal wastegate applications.
Featuring a large diaphragm working area, the IWG75 provides superior mechanical advantage and the broadest possible boost curve with more sensitive control. This ensures consistent, predictable boost delivery and enhanced tuning flexibility for RB26 builds. Constructed from high-grade billet aluminum with stainless steel rods and clevis, it offers the strength and reliability required for demanding street or track use. The proprietary Silicon Nomex diaphragm and Turbosmart’s unique locking collar design further ensure long-term durability and precise performance.
This 14 PSI actuator is ideal for enthusiasts running upgraded Garrett or HKS turbochargers, allowing for improved efficiency and power delivery over stock components. It is not intended for use with OEM ceramic RB26DETT turbos but instead for those who want a proven upgrade that keeps the factory turbo position. Terra Firma Automotive is proud to supply the Turbosmart IWG75 range, helping Skyline and RB26 owners unlock the full potential of their engines.
