The Garrett GT2871R Ball Bearing Turbo in the standard 56 trim configuration is engineered for enthusiasts running small displacement engines who demand quick spool without sacrificing top-end flow. Its dual ball bearing core design delivers a level of throttle response that traditional journal bearing turbos can’t match, making it a favorite for builders chasing a stealthy but serious power upgrade. Whether you’re running the standard internally gated T25 housing or configuring a T3/T4 drop-in setup for an older platform, this unit is built to bolt in and perform.

Performance & Application

This GT2871R is purpose-built for small displacement engines up to 2.2L, offering the ultimate spool-up time compared to other units in its class. Its external packaging is identical to that of the GT28RS, allowing enthusiasts to step up to roughly 400HP of flow capacity as a nearly invisible upgrade, without needing to re-arrange surrounding hardware. For applications requiring a retrofit into older T3-based turbine housing setups, an optional T3/T4 drop-in style turbine housing is available, supporting either internal or external wastegate configurations. This makes the GT2871R equally suited to a clean OEM-style up
