IWG75 Polaris RZR 5psi

The Turbosmart IWG75 Upgraded Wastegate Actuator is engineered to deliver maximum boost response and improved control for factory frame turbochargers. Designed as a performance upgrade over OEM actuators, it enhances spool characteristics, boost stability, and overall torque delivery across the RPM range.

IWG75 Polaris RZR 5psi Product Overview

The IWG75 series increases the actuator’s working ratio compared to factory components. This is achieved through a larger effective diaphragm surface area and revised internal spring calibration, allowing greater leverage over boost pressure and exhaust backpressure—while maintaining fast, precise response.

With factory base pressure, you can expect:

  • Earlier boost onset
  • Broader boost and torque curve
  • Improved boost hold into higher RPM

Vehicle Fitment

Suitable for:

  • Polaris RZR Turbo
  • Polaris RZR Turbo S

(Refer to vehicle application guide for exact fitment confirmation.)

Features

  • High-performance IWG75 actuator platform
  • Proprietary Silicon Nomex diaphragm for heat resistance and durability
  • Optional spring range from 3psi to 26psi
  • CNC machined billet aluminium construction
  • Stainless steel rod and clevis for strength and reliability
  • Turbosmart locking collar system for precise preload adjustment

Notes

  • Designed for direct performance upgrade on Polaris turbo applications
  • Increased boost setups may require supporting modifications and ECU tuning/recalibration
