Dual Ball Bearing GT2871R is great for small displacement engines up to 2.2L and has the ultimate spool up time compared to other units. This turbo has a flow capacity of about 400HP. The external packaging of this turbo is identical to that of the GT28RS and can be a nice stealthy upgrade to step up to 400HP of flow without much re-arrangement.
Optional "T3/T4 drop-in" style turbine housing available for an easy retrofit into older T3 based applications where T3 turbine the inlet flange is required and either internal or external wastegate are used (internal wastegate assembly is not included when ordering T3/T4 drop-in configuration).
The standard configuration (off the shelf and out of the box) GT2871R turbo, is pre-assembled with the standard T25 flanged turbine housing, which is internally gated, and the 5 bolt GT28 style discharge. This housing selection INCLUDES an internal wastegate actuator with the turbo.
