Turbocharger for Buick Encore (2016-2019) 1.4L

Direct-Replacement Turbocharger for 2016-2019 Buick Encore (Gamma II)

What it Does: The replacement turbocharger restores factory boost pressure and engine efficiency on the 2016-2019 Buick Encore by replacing worn rotating assemblies and failed wastegate mechanisms.

The Stock Buick Encore Turbocharger Failure Points

The factory turbocharger fitted to the GM LE2 1.4L engine is vulnerable to chronic heat soak and severe thermal cycling. Over mileage, high exhaust gas temperatures cause hairline cracking in the cast turbine housing and loosen the internal wastegate flapper arm pivot bushing. This deterioration triggers persistent low-boost fault codes (such as P0299), sluggish off-the-line acceleration, and compromised fuel economy. Furthermore, oil carbonization in restrictive oil supply circuits accelerates journal bearing wear, leading to shaft play, compromised oil seals, and blue smoke from oil entering the intercooler tract.

The Engineering Solution

Constructed around the proven TD025L4BR architecture, this direct-fit unit features a reinforced, heat-resistant turbine housing designed to resist thermal stress and fatigue cracking. The rotating assembly utilizes dynamic multi-plane balancing to ensure vibration-free spooling across the entire powerband. Built with high-grade floating journal bearings, factory-spec oil and coolant passages, and an integrated electronic wastegate actuator, this unit matches OEM flow parameters without requiring ECU recalibration. Replacing the unit resolves boost leaks, eliminates wastegate rattle, and restores factory throttle response.

Frequently Asked Questions & Fitment Warnings

Does this fit the Gamma II Encore?

Yes, this is a direct fit for the 2016-2019 Buick Encore equipped with the LE2 direct-injected 1.4L engine. Confirm your vehicle uses the LE2 engine code before ordering, as this unit does not fit older port-injected LUV engine variants.

Should the oil feed and return lines be replaced during installation?

Yes, replacing or thoroughly clearing the oil supply lines and changing the engine oil and filter is required to prevent residual carbon contaminants from damaging the new floating journal bearings.
