Turbosmart IWG-75 12PSI Internal Wastegate Actuator - Ford Focus RS Mk3 2.3 EcoBoost (2016-2018) Turbo Actuator Upgrade IWG75 - Direct Fit, Improved Boost Control

Turbosmart IWG-75 12 psi Wastegate Canister for Ford Focus RS Mk3 2.3T

Unlock sharper response and rock-steady boost with the Turbosmart IWG-75 12 psi actuator, a direct bolt-on replacement for the 2016 to 2018 Focus RS Mk3 2.3-litre turbo. This premium billet alloy boost actuator tightens up boost control, helps the turbo spool sooner and maintains target pressure more consistently for fast road and track use. If you want punchier mid-range and stronger pull to redline without sacrificing day-to-day drivability, this IWG75 upgrade delivers.

Performance highlights

• 12 psi base pressure pneumatic actuator for confident, repeatable boost regulation
• Quicker turbo spool for livelier throttle response and reduced lag
• Holds commanded boost harder at higher rpm for improved top-end power stability
• CNC billet construction for durability and reliability under heat and load
• Locking collar spring system for easy future spring changes when tuning
• Direct bolt-on to the factory turbocharger with no fabrication required

Why enthusiasts choose it

Factory actuators often open early which can bleed off pressure and soften the hit. The IWG-75’s stiffer base spring and precise control reduce wastegate creep so the turbocharger reaches and holds target boost more effectively. Whether you are running a stock calibration or planning a remap with supporting mods, this is a high value upgrade that complements both standard and tuned setups.

Ideal for

• Focus RS Mk3 owners wanting crisper throttle feel and better boost consistency
• Fast road and track builds needing stable control at sustained high load
• Cars being mapped where dependable base pressure helps the tuner deliver consistent results

Compatibility

• Ford Focus RS Mk3 2.3 turbo petrol 2016, 2017, 2018
• Fits the standard turbocharger using the supplied hardware

Real world results

We have installed this actuator on our own cars and customer builds with excellent feedback. Drivers report more urgent spool, stronger mid-range torque and a smoother, more repeatable boost curve that inspires confidence on B-roads and circuits alike.

Fitting and setup

Professional installation is recommended to set rod length and preload correctly. MJ Modifications offers fitting and setup at our Warwickshire workshop. Request a quote at info@mjmodifications.co.uk.

Note: 12 psi refers to the actuator’s base spring pressure. Final peak boost is managed by the ECU or an external controller. If you change spring pressure later, calibration may be required to maintain correct targets.
