Turbosmart Gen-V WG38/40 3psi Black Inner Spring
This inner spring sets the base boost pressure at 3psi for Turbosmart Gen-V WG38 and WG40 wastegate actuators used in high-performance turbocharged vehicles. It provides accurate low-end boost control in custom turbo setups across various makes and models. Pair it with outer springs to achieve higher pressures reliably.
Key Features
- 3psi Rating: Delivers exact base boost pressure for responsive throttle and minimal lag in street or track applications
- Gen-V Compatibility: Direct fit for WG38 and WG40 internal wastegate actuators with no modifications needed
- High-Temperature Steel: Constructed from chrome silicon wire for enduring extreme heat and repeated cycles without fatigue
- Black Finish: Color-coded for quick identification during installs and maintenance
- Precision Manufacturing: Ground and pre-set in Australia for consistent performance and longevity
Product Notes
- Combine with Turbosmart outer springs to adjust total boost up to 26psi based on actuator model
- Inspect spring seating during boost creep troubleshooting for optimal function
- Packaged securely to prevent damage during transit
Installation Notes
- Professional installation recommended.
- Depressurize turbo system and remove wastegate actuator cap to access inner spring
- Compatible with factory Turbosmart hardware and silicone diaphragm bases

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...
