The Garrett GT1752S PowerMax turbocharger kit for the 2021+ Ford Bronco 2.7L EcoBoost is a direct-fit performance upgrade for the standard twin-turbocharged V6 Bronco platform. Where the 3.0L EcoBoost Bronco Raptor uses the GT1752S in a twin-kit configuration, the 2.7L Bronco receives a single matched-pair kit (926432-5001S) that addresses both turbocharger positions on the 2.7L engine. Garrett's PowerMax series is built around a larger compressor wheel and matched turbine section in a factory-footprint housing, which delivers improved surge margin and increased peak flow compared to the stock unit without requiring exhaust or intake fabrication. For a 2021+ Bronco running a performance tune or used in demanding trail or high-altitude environments, the Garrett GT1752S PowerMax is the upgrade path designed for the 2.7L EcoBoost architecture. This guide covers the kit's specifications, fitment, and whether it is the right upgrade for the application.
Fitment: Garrett GT1752S PowerMax for 2021+ Ford Bronco 2.7L EcoBoost
The Garrett GT1752S PowerMax kit (926432-5001S) fits the following applications:
- 2021+ Ford Bronco with 2.7L twin-turbo EcoBoost V6 (available in Outer Banks, Badlands, and Wildtrak trim levels that specified the 2.7L option)
The 2.7L EcoBoost V6 in the Ford Bronco uses a parallel twin-turbo arrangement with two small-frame turbochargers mounted at the cylinder bank exhaust outlets. Both turbos spool simultaneously under throttle demand and work together to supply the intercooler. The GT1752S PowerMax kit addresses both turbocharger positions with matched units, which is required for balanced boost production on a parallel twin-turbo engine. Installing non-matched turbos in a parallel arrangement results in uneven boost contribution from each bank that cannot be fully corrected through calibration.
The GT1752S installs at the factory turbo mounting locations using the factory exhaust manifold connections, oil feed and return ports, and coolant lines. The kit is designed for a direct bolt-in installation without modifications to the factory intake piping, intercooler, or exhaust system, which allows the upgrade to be completed without additional supporting fabrication work.
Top Picks: Garrett GT1752S PowerMax for the 2.7L Bronco
The Garrett 2021+ Ford Bronco 2.7L GT1752S PowerMax Turbocharger Kit (926432-5001S) is the Garrett direct-fit performance solution for the 2.7L EcoBoost Bronco. Garrett designs the GT1752S PowerMax with a larger compressor wheel inducer than the factory turbo, a matched turbine section for correct A/R balance with the larger compressor flow, and a precision-balanced rotating assembly. The PowerMax designation in the Garrett lineup refers to the direct-fit performance tier -- these units use factory connection hardware and mounting dimensions rather than universal fittings, so they install cleanly in the factory location without adapter plates or custom oil lines.

The 2.7L EcoBoost GT1752S PowerMax delivers its primary benefit in two areas: improved surge margin at elevated boost levels, and increased peak compressor flow for applications where a tune raises the boost target above factory. The factory 2.7L EcoBoost turbos are correctly sized for the OEM boost calibration but operate near their surge boundary when a performance tune pushes the boost setpoint higher. The GT1752S moves the surge line outward on the compressor map, which allows the tuned boost target to be sustained without the compressor instability the factory unit experiences in the same conditions. At stock boost levels, the GT1752S produces results similar to the factory unit, but without the surge margin pressure that exists in the factory setup on a calibrated vehicle.
Match to the Build
- Stock 2.7L Bronco used for trail driving at elevation: High-altitude operation reduces air density, which pushes the factory compressor closer to its surge boundary at a given boost target; the GT1752S larger compressor provides additional surge margin that preserves boost stability in thin air conditions that challenge the factory turbo sizing
- Tuned 2.7L Bronco with a stage 1 power calibration: A stage 1 tune that raises boost above the factory setpoint is the primary use case for the GT1752S -- the larger compressor supports the higher flow demand without surge at the elevated boost level the tune commands; this is where the upgrade's performance benefit over the factory unit is most directly measurable
- 2.7L Bronco with modified intake and exhaust: Aftermarket intake and exhaust on the 2.7L EcoBoost reduce backpressure and improve breathing, which increases the demand on the turbocharger to fill the larger air volume; the GT1752S is sized appropriately for the flow demand of a 2.7L Bronco with intake and exhaust modifications alongside a supporting tune
- High-mileage 2.7L Bronco needing turbo replacement: A 2021+ Bronco with accumulated mileage and worn factory turbos is a candidate for the GT1752S as a replacement-with-upgrade rather than an OEM-spec rebuild; the cost difference is modest and the GT1752S provides improved surge margin and long-term durability the factory unit does not deliver
Signs the 2.7L EcoBoost Turbos Need Attention
- Compressor surge sound under hard acceleration -- a cyclic flutter or stutter from the intake during wide-open throttle operation indicates the factory compressor operating past its surge line; more common on tuned vehicles or at altitude; the GT1752S moves the surge limit outward and eliminates the condition in most cases
- Boost pressure failing to reach commanded target on a calibrated vehicle -- the factory compressor reaching its flow limit before the tune's boost target is achieved; audible as a plateau in power delivery at high rpm; a larger compressor delivers the flow the calibration commands
- Oil consumption increase without visible external leaks -- turbocharger compressor seal wear allowing oil to pass into the intake; typical on high-cycle EcoBoost applications; requires turbocharger inspection and likely replacement
- Boost that builds normally but drops off above a certain engine speed -- the factory compressor reaching its maximum flow rate before the engine reaches its power peak; characteristic of a compressor that is correctly sized for factory boost but undersized for a modified application's demand above the factory operating point
Frequently Asked Questions
Does the 2.7L EcoBoost Bronco GT1752S kit fit both turbo positions?
Yes. The Garrett GT1752S kit (926432-5001S) for the 2.7L Bronco includes the hardware for both turbocharger positions. The 2.7L EcoBoost is a parallel twin-turbo engine and both turbos must be the same specification for balanced boost production. Garrett packages the 2.7L Bronco upgrade as a complete matched set for exactly this reason.
What is the difference between the 2.7L kit (926432-5001S) and the 3.0L Bronco Raptor kit (926432-5002S)?
The two kits are calibrated for different engines. The 2.7L EcoBoost and 3.0L EcoBoost use different turbocharger sizing, exhaust housing A/R ratios, and connection hardware that match the specific airflow and exhaust energy characteristics of each engine. The part numbers are distinct because the turbocharger specifications are not interchangeable between the 2.7L and 3.0L applications, even though both use the GT1752S compressor wheel designation. Always order by engine displacement to ensure the correct kit for the application.
Does the GT1752S require a tune on the 2.7L Bronco?
A tune is not required for installation. The GT1752S can be installed and the vehicle driven at factory boost levels immediately. The performance benefit of the larger compressor -- reduced surge, higher peak flow, better efficiency at elevated boost -- is only accessible when a calibration raises the boost target to take advantage of the larger compressor's operating range. For a stock-boost vehicle, the GT1752S still provides improved surge margin and durability compared to the factory unit at the same boost level.
Bottom Line
The Garrett GT1752S PowerMax kit for the 2021+ Ford Bronco 2.7L EcoBoost is the direct-fit performance turbocharger upgrade for the standard Bronco V6 platform. It installs in the factory locations without fabrication, includes hardware for both turbo positions, and delivers a larger compressor map with improved surge margin compared to the stock unit. Pair it with a supporting ECU calibration to access the full performance benefit, or install it as a durable factory-footprint upgrade with better high-boost stability than the factory turbo provides.
