Garrett GTX3067R Turbochargers

What the Garrett GTX3067R is

Garrett’s 2012 catalog calls the GTX3067R the smallest GTX30R: a dual ball bearing, oil and water-cooled turbo with a forged, fully machined 10-blade compressor wheel of 49.7 / 67.4 mm (55 trim) and a 60 mm, 84 trim turbine wheel, rated at 275 to 500 horsepower on engines of 1.8 to 3.0 liters, with more peak power than the GTX2867R. It was sold without turbine housing: on the turbine side it takes GT and GTX 30-series housings (T3 or T4 inlet, 0.63 to 1.06 A/R), and on the compressor side it interchanges with the GT2860RS and GTX28R. Garrett’s current catalog lists the GTX3071R and GTX3076R Gen II in the GTX30 size.

This page lists GTX3067R turbos with T3 undivided and T31 narrow turbine housings (0.48 to 0.82 A/R, V-band or 4-bolt exit), a bolt-on turbo for the Ford Focus ST 2.0L EcoBoost, a version without turbine housing, a partial turbo and the CHRA. 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.
