Garrett GT2871R 52 trim turbo with GT28R style Compressor Housing NO ACTUATOR

The Garrett GT2871R 52 trim turbocharger with GT28R style compressor housing is built for enthusiasts running small-displacement engines who want a serious jump in flow capacity without disrupting the factory-style packaging. This dual ball bearing unit is engineered for rapid spool and strong top-end power delivery, making it a favorite for SR20DET builders looking to step up from a GT28R-class turbo while keeping a familiar external footprint. It’s supplied as a bare turbo assembly — no wastegate actuator or bracket included — giving tuners flexibility to select the actuator setup that matches their specific kit and housing clocking requirements.

Performance & Application

This GT2871R configuration is purpose-built for small displacement engines up to 2.2L, delivering ultimate spool-up time compared to other units in its class. Its 71mm/52 trim compressor wheel paired with the .60 ar GT28R style compressor housing and 53.85mm/76 trim turbine wheel combine to produce quick-spooling response while supporting a flow capacity of about 400HP. Because the external packaging can be made identical to that of the GT28R when paired with the appropriate actuator, this turbo offers a stealthy way to significantly increase flow without major re-arrangement of the engine bay. It’s an ideal choice for enthusiasts seeking a meaningful power upgrade while retaining a factory-style appearance.
