Garrett GT2871R Turbo Top Mount T3 Inlet / GT31 V Band Outlet for SR / KA / RB
The Garrett GT2871R Turbo Top Mount Kit (SKU: ER-T3GT2871R-TopM3in) is the ideal solution for SR, KA, or RB engine builds looking to maximize the advantages of a top-mount setup without the lag of larger turbos like the GT3071R. Designed to deliver quicker spool, efficient power, and consistent performance, this setup is perfect for drivers who demand responsiveness and reliable horsepower on a T3 flange manifold.
This turbo features a complete Garrett GT2871R CHRA paired with an ATP .60 A/R compressor housing (3" inlet / 2" outlet) and a GT31-style turbine housing with a T3 inlet and 2.5" V-band outlet for optimal flow and ease of installation. Supporting hardware is included for a seamless install, and each unit comes fully assembled. Please note, this is not an off-the-shelf product—some components may be special ordered, so allow 2–3 weeks for shipping.
This is the same turbo setup featured on the Banana S14, pushing 450whp at just 18psi.
