Garrett GTX2867R Turbochargers

What the Garrett GTX2867R is

The GTX2867R is a Garrett GTX28-series ball-bearing turbo sold in two generations. Garrett rates the current Gen II at 275 to 550 horsepower on engines of 1.4 to 2.5 liters, with an 8 mm dual ceramic ball bearing cartridge, a 50 / 67 mm compressor wheel, a 54 / 47 mm turbine wheel and a maximum speed of 165,000 rpm (supercore 849894-5002S); its turbine kits are T25-inlet internally wastegated (0.64 and 0.86 A/R) or V-band (0.57 and 0.72 A/R). Garrett’s 2015 catalog rated the Gen I at 275 to 480 horsepower on 1.8 to 3.0 liters, with a forged, fully machined billet compressor wheel. Garrett says Gen II compressor housings are not interchangeable with Gen I compressor wheels.

This page lists Gen II and Gen I GTX2867R turbos, bolt-on kits (Focus ST, Fiesta ST, SR20DET, RB26DETT, Mustang 4.6L), supercores, CHRAs and a compressor housing; the title of each listing says which generation it is. Garrett’s own guidance on turbine housings: a smaller A/R gives quicker boost response and more turbine power at low engine speed; a larger A/R lets the wheel flow more, with lower back pressure and more power at high engine speed.
