What the Garrett GT3076R is
The GT3076R is a Garrett GT30-series ball-bearing turbo with a water-cooled CHRA. Garrett rates it at 310 to 525 horsepower; its current page gives engines of 2.0 to 3.5 liters, while its 2015 catalog said 1.8 to 3.0 liters. It has a 57 / 76 mm, 56 trim compressor wheel in a 0.60 A/R housing and a 60 / 55 mm, 84 trim turbine wheel (supercore 836028-5003S), and uses the same GT30 turbine kits as the GTX3071R, interchangeable with GT and GTX Gen I and Gen II 30-series supercores.
This page lists complete GT3076R turbos, a supercore, CHRAs and housings. 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.
