A/R (area-to-radius ratio) is Garrett's turbine A/R for each GBC turbo. For the GBC17-250, GBC20-300 and GBC22-350, Garrett states that the turbine housing inlet flange is standard T25 and the outlet has a 5-bolt pattern, the same flange as the GT25 and GT28 turbos. For the GBC14-200, Garrett's flange diagram (linked below) shows the inlet and outlet flanges, and Garrett states that the turbine housing inlet can be machined to a V-Band with a 2.24 in. (57 mm) outside diameter for use with 1.75 in. tubing.

Wastegate Actuators and Gaskets

Garrett calibrates its GBC turbos with a 0.5 bar actuator (480009-0009). 1.0 bar (480009-0006) and 1.5 bar (480009-0010) actuators are sold separately.
Garrett does not state whether an actuator is included with these assemblies. Call us before ordering if you need one.
Garrett lists the T25 turbine inlet gasket (447802-0001) and the 5-bolt turbine outlet gasket (770119-0001) for the GBC17-250, GBC20-300 and GBC22-350.
