The VG20ET offered in the Japanese 200Z, 200ZG, and 200ZS, was basically a VG30ET with the bore and stroke decreased. It came with a single Garret based TB250 turbocharger that had two different wastegate settings. At low speeds, the turbo's flap (wastegate) would stay closed improving the response at low RPMS. At high speeds, the flap would stay open, decreasing resistance and increasing exhaust flow. At its maximum flow, the flap would open at an angle of 27-degrees, while the A/R ranged from 0.21 ~ 0.77.

Though the intake and exhaust manifolds look similar to the VG30ET units, they do not interchange due to the smaller deck height of the VG20.
