Garrett GT1752S PowerMax 2.7L Bronco: Specs, Fitment, Worth It?

The Garrett turbocharger GT1752S PowerMax kit for the 2021+ Ford Bronco 2.7L EcoBoost is a direct-fit twin-turbocharger upgrade kit produced by Garrett for the 2.7L twin-turbo engine used in the Bronco Badlands, Wildtrak, and other high-content Bronco trims. The 2.7L EcoBoost is Ford's mid-range twin-turbo gasoline engine, producing 330 horsepower in the factory Bronco configuration. The GT1752S PowerMax upgrade targets the factory twin-turbo configuration's compressor ceiling on a tuned build -- the factory turbos are sized for the factory 330 hp output and reach their efficient limit when a tune raises boost and fuel targets past the stock calibration. This review covers the GT1752S PowerMax specs, fitment for the 2021+ Bronco 2.7L, what build level it fits, and whether this Garrett turbocharger upgrade is the right choice.

Garrett GT1752S PowerMax 2.7L Bronco Kit Specs

The Garrett GT1752S PowerMax Turbocharger Kit (926432-5001S) for the 2021+ Ford Bronco 2.7L EcoBoost includes both turbocharger assemblies for the twin-turbo configuration. Key specifications:

• Application: 2021+ Ford Bronco with the 2.7L EcoBoost twin-turbo engine (Badlands, Wildtrak, First Edition, and compatible 2.7L-equipped Bronco trims)
• Configuration: Complete twin-turbo upgrade kit -- both right-hand and left-hand Garrett GT1752S PowerMax turbochargers for a matched simultaneous upgrade of both sides
• Format: Direct-fit -- designed to mount to the 2.7L EcoBoost's factory twin-turbo location without custom manifolds or fabricated oil and coolant lines
• Series: Garrett GT1752S PowerMax -- the same compressor and turbine platform as the 3.0L Bronco Raptor and Ranger Raptor kit (926432-5002S) but specified for the 2.7L application and its factory mounting configuration

The 2.7L EcoBoost in the 2021+ Bronco uses a twin-turbo configuration with relatively compact turbos sized for the factory output ceiling and the Bronco's broad operating envelope -- from low-RPM trail crawling to highway speed. The compact factory turbos spool quickly across the RPM range but reach their compressor ceiling before the fuel system does on a tuned engine. The GT1752S PowerMax is sized to raise the ceiling while maintaining the spool characteristics appropriate for the 2.7L displacement.

Top Picks: GT1752S and the 2.7L Bronco Upgrade Lineup

The Garrett GT1752S PowerMax Turbocharger Kit for 2021+ Ford Bronco 2.7L EcoBoost (926432-5001S) is the direct-fit Garrett upgrade for the Bronco 2.7L twin-turbo system. The matched RH/LH kit upgrades both compressors simultaneously for balanced boost delivery across both banks -- the correct approach for a parallel twin-turbo engine where mismatched turbo sizing between banks creates fueling imbalance that the tune must compensate for.

For the complete 2.7L Bronco performance build, the GT1752S PowerMax kit pairs with a tune calibrated for the new compressor maps, an upgraded intercooler to manage the additional heat load from higher boost, and a supporting high-flow intake to match the improved turbo airflow capacity.

Match to the Build

The Garrett GT1752S PowerMax kit is the right Garrett turbocharger upgrade for these 2021+ Bronco 2.7L configurations:

• 2021+ Bronco 2.7L with stage 1-2 tune, intake, and intercooler, factory turbos at the compressor ceiling: This is the use case the GT1752S is designed for. After a tune and supporting intake and intercooler upgrades have raised the build to the point where the factory turbos are limiting further power output, the GT1752S delivers the compressor capacity the tune has been waiting for. The matched kit upgrades both sides simultaneously for a balanced result.
• Bronco 2.7L used in sustained high-demand operation: For a Bronco 2.7L that sees sustained hard use -- towing, trails with long climbs under load, or track use -- the GT1752S PowerMax compressor efficiency at higher boost levels reduces compressed air temperature compared to the factory turbos running outside their efficient range, which benefits intercooler outlet temperature and overall engine thermal load.
• Builds requiring matched twin-turbo upgrade: For any 2.7L EcoBoost build where balanced boost delivery across both banks is required, the matched GT1752S kit is the correct approach. Individual side replacement creates imbalance in a parallel twin-turbo arrangement.

Signs the Factory 2.7L Bronco Turbos Have Reached Their Limit

• Boost pressure ceiling on the dyno at wide-open throttle before the tune's fueling target is reached -- the factory compressor maps are at maximum flow before the fuel system is
• Power plateau on a tuned 2.7L Bronco after intercooler and intake upgrades are confirmed at full spec -- the factory turbos are the remaining ceiling
• Compressor outlet temperature elevated under sustained boost even with an upgraded intercooler -- the factory turbos are running outside their efficiency islands and producing hot compressed air
• Boost imbalance between banks appearing in logging data on a high-mileage or hard-used 2.7L EcoBoost -- uneven factory turbo wear affecting balanced delivery

Frequently Asked Questions

Does the GT1752S 2.7L kit (926432-5001S) differ from the 3.0L Bronco Raptor kit (926432-5002S)?

The two kits share the GT1752S PowerMax turbocharger platform but are specified for different Ford applications. The 926432-5001S is for the 2021+ Bronco 2.7L EcoBoost, while the 926432-5002S is for the 2022+ Ford Bronco Raptor and Ranger Raptor 3.0L EcoBoost. The mounting configuration, compressor outlet geometry, and installation hardware differ between the two engine applications -- do not substitute one kit for the other.

Is a tune required with the GT1752S PowerMax on the 2.7L Bronco?

Yes. A tune calibrated for the Garrett GT1752S compressor map is required to realize the power gain. The factory calibration is built around the factory turbo maps, not the GT1752S, so running the kit on the stock tune leaves significant performance unrealized. Use a tuner who actively supports the GT1752S on the 2.7L EcoBoost Bronco platform for a properly calibrated result.

Does the 2.7L Bronco GT1752S kit cover all Bronco trim levels with the 2.7L engine?

The Garrett GT1752S kit (926432-5001S) is specified for the 2021+ Ford Bronco with the 2.7L EcoBoost. This covers the Badlands, Wildtrak, First Edition, and other Bronco trims equipped with the 2.7L engine option. Confirm the specific Bronco has the 2.7L EcoBoost before ordering -- Bronco trims with the 2.3L EcoBoost use a different single-turbo configuration and are not the application for this kit.

Bottom Line

The Garrett GT1752S PowerMax turbocharger kit (926432-5001S) is the correct twin-turbo upgrade for a 2021+ Ford Bronco 2.7L EcoBoost that has been tuned and supported to the point where the factory twin turbos are limiting further power output. The matched RH/LH kit upgrades both sides simultaneously, maintains the direct-fit factory mounting, and delivers the compressor capacity needed to support a stage 2 tune on the 2.7L EcoBoost platform. Confirm the tune is calibrated for the GT1752S maps, pair with the stage 2 intercooler and intake already in place, and this Garrett turbocharger kit delivers the results the 2.7L Bronco build has been set up for.
