text: VG20ET The VG20ET was based on the VG20E, but with an added an Variable-geometry turbocharger. The VG20ET produces . This SOHC motor debuted at the same time as the VG20E. Also coming with the Y30, this motor was known as the "Jet Turbo", and came with the Nissan Leopard models XS, and XS-II Grand Selection. Contrary to the VG30ET that came out in the US, the VG20ET came with an intercooler in certain models to push the horsepower output to , a great jump from the normally aspirated VG20E. The turbo included with the VG20ET had two different settings. At low speeds, the turbo's wastegate would stay closed improving the response at low rpm. 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. Being that the VG20ET had a short stroke , it was thought to have insufficient low end torque. Nevertheless, the VG20ET was a great improvement over the VG20E.
