The FA24F turbo upgrade market for the 2022 and newer WRX has been limited until now. Most turbo options for the FA24 platform require sourcing components separately and piecing together a kit. IAG Performance has changed that with the IAG 600 Ball Bearing Turbocharger, the most complete bolt-on turbo upgrade available for the Subaru WRX FA24F platform. This guide covers what it delivers, what the install requires, and whether it fits your build.

What Is the IAG 600 Ball Bearing Turbocharger
The IAG 600 is IAG Performance’s flagship bolt-on turbo upgrade for the 2022 and newer WRX FA24F. It is rated for up to 600 BHP and comes as a complete kit, IAG Electronic Wastegate, full hardware kit, and everything needed for the install included in the box. No sourcing additional components separately. No piecing together a kit from multiple vendors.
IAG describes this as the most complete FA24 turbo kit on the market. For 2022+ WRX owners who want a serious turbo upgrade without the complexity of a custom turbo build, that completeness is the core value proposition. The kit is engineered specifically for the FA24F, not adapted from another platform, not a universal fit solution.
What the IAG 600 Actually Delivers on the FA24F
IAG has proven the IAG 600 on their own test vehicle. On a stock FA24F engine with a proper tune on 93 octane pump gas, the result is 374 WHP. On E60 fuel with a flex fuel setup and a tune, the same stock engine produces 450 WHP. Those are real numbers on a stock bottom end, not estimates or projections.
For context, the stock 2022 WRX produces approximately 230 to 240 WHP at the wheels. The IAG 600 on 93 octane represents a 55 to 60 percent power increase on a stock engine. On E60 it pushes past 450 WHP without touching the internals. For owners building toward more power with a built FA24F bottom end, the 600 BHP rating gives the turbo headroom the build needs. Our post on how much power the FA24 makes stock and built covers the full power picture for the platform at each stage.
Ball Bearing vs Journal Bearing: Why It Matters
The IAG 600 uses ball bearing construction rather than the journal bearing design found in most OEM and entry-level aftermarket turbos. The difference is felt throughout the entire RPM range, not just at peak power.
Ball bearing turbos spool faster because the rotating assembly has less friction to overcome. Boost builds earlier in the rev range which improves throttle response and makes the car feel stronger in daily driving situations where the engine is not always at high RPM. Ball bearing construction also has a longer service life than journal bearing designs under sustained high-boost use. For a street-driven daily that also sees performance driving, ball bearing construction is the right choice.
What the IAG 600 Kit Includes
The kit completeness is one of the strongest differentiators for the IAG 600. Most FA24 turbo options require sourcing the turbo core, wastegate, hardware, and supporting components separately. The IAG 600 arrives with everything needed for the install.
The IAG Electronic Wastegate is included in the kit. This is a significant addition, electronic wastegate control allows more precise boost management and works directly with the FA24F platform’s engine management system. The full hardware kit covers gaskets, fasteners, and supporting components. For owners who want to install the turbo without hunting for additional parts, this is a complete solution.
What the Build Needs to Support the IAG 600
IAG is direct on this point: tuning is required. Do not install this turbo without a proper tune. The FA24F ECU needs to be calibrated for the increased airflow and boost the IAG 600 produces. Running it on a stock or outdated map is not an option. Understanding what EFI tuning does for your WRX explains exactly why the tune is what unlocks the upgrade rather than just the hardware.
To reach the 450 WHP number on E60 fuel, a flex fuel setup is required alongside the tune. The COBB flex fuel kit for WRX covers how the flex fuel system works on the FA24 platform and what the complete setup involves.
At 374 to 450 WHP the stock intercooler becomes a restriction point. A proper intercooler upgrade matched to the turbo output is part of a complete build at this power level. Browse intercooler kits for WRX to find the right option for the FA24F platform. Fueling also needs to match what the turbo demands, the WRX fuel system upgrades hub covers injectors and fuel pump requirements at this power level.
Engine mounts keep the drivetrain stable under the increased torque the IAG 600 produces. IAG makes FA24-specific engine mount sets for the 2022+ WRX platform. Browse engine mounts for WRX to find the right option for the build.
Is the IAG 600 Right for Your 2022 WRX Build
For 2022 and newer WRX owners targeting 374 WHP on pump gas with a proper tune, the IAG 600 delivers that on a stock engine. When it comes to owners targeting 450 WHP on E60 with a flex fuel setup, it delivers that too. For builds going further with a built FA24F bottom end, the 600 BHP rating gives the turbo the headroom the build needs.
The one situation where the IAG 600 is not the right next step is for owners who are not ready to tune. IAG is clear that tuning is required before this turbo goes in. Getting the tune sorted before the install is part of the build plan, not an afterthought. Browse the WRX turbo and airflow upgrades hub to see how the IAG 600 fits into the complete forced induction picture for the FA24 platform.
