Turbosmart IWG75 Garrett GT2860RS 5 PSI Black Internal Wastegate Actuator for 2004-2021 Subaru STI & 2003-2006 Mitsubishi Evo
The Turbosmart IWG75 is a direct replacement internal wastegate actuator designed specifically for the Garrett GT2860RS turbocharger set to 5 PSI actuation. It fits popular performance vehicles like 2004-2021 Subaru Impreza WRX STI and 2003-2006 Mitsubishi Lancer Evolution equipped with this turbo. This actuator delivers consistent boost response faster acting than stock for improved throttle feel and power delivery across the RPM range.
Key Features
- Direct Bolt-On Fit: Engineered as a plug-and-play replacement for the Garrett GT2860RS OEM actuator no modifications needed for seamless installation on compatible turbos
- 5 PSI Actuation: Factory set to 0.35 bar with Nitronic 60 stainless steel spring provides stable low-boost control ideal for street and track setups
- Billet Aluminum Construction: CNC machined from 6061-T6 aluminum black anodized finish resists corrosion and withstands extreme heat up to 500 degrees F
- Reinforced Diaphragm: Silicone Nomex diaphragm offers superior flexibility and puncture resistance for long-term reliability under high pressure
- Quick Spool Response: Reduces wastegate flutter enhances turbo efficiency for sharper boost onset and reduced lag
Product Notes
- Confirm your turbocharger is Garrett GT2860RS before purchase actuator is model-specific
- Base boost is 5 PSI higher pressures achieved by swapping springs sold separately
- Packaged securely to prevent damage during transit
Installation Notes
- Professional installation recommended.
- Bolt-on design uses existing mounting points no cutting or welding required
- Compatible with factory Garrett hardware and aftermarket turbo manifolds

Forced Induction
Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...
