IWG75 Fiat 124 Spider/500T/L/X/Abarth 2012+ 7psi Outer Spring Fitted

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 full RPM range.

IWG75 Fiat 124 Spider/500T/L/X/Abarth 2012+ 7psi Outer Spring Fitted Product Overview

The IWG75 series features an increased working ratio compared to factory wastegate actuators. 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, responsive operation.

With factory base pressure, you can expect:

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

Available Options

  • 7psi / 0.5 Bar – TS-0629-1072 (direct replacement, factory compatible)
  • 10psi / 0.7 Bar – TS-0626-1102

Features

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

Fitment

Direct bolt-on upgrade for factory turbochargers on:

  • Fiat 124 Spider
  • Fiat 500 Abarth
  • Fiat 500T

Notes

  • The 7psi version is suitable as a direct replacement and works with factory calibration
  • Higher spring pressures may require supporting modifications and ECU tuning/recalibration
