About the Nissan VG30E Engine

The VG engine family consists of V6 piston engines designed and produced by Nissan for several vehicles in the Nissan lineup. The VG series started in 1983 becoming Japan's first mass produced V6 engine. VG engines displace between 2.0 L and 3.3 L and feature an iron block and aluminum heads. The early VG engines featured SOHC, 12 valve heads. A later revision showcased a slightly different block, and DOHC, 24 valve heads with Nissan's own variation of variable valve timing for a smoother idle and more torque at low to medium engine speeds. The block features a single piece main bearing cap. The production blocks and production head castings are utilized successfully in the Nissan GTP ZX-Turbo and NPT-90 race cars which won the IMSA GT Championship three years in a row.The VG series engine found its way into thousands of Nissan vehicles, starting in 1984. The VG design had been retired in 2004, by which time period all V6-powered Nissans had switched to the VQ engine series.The 3.0 L (2,960 cc) VG30E produced 153 hp (114 kW) and 182 lb. Bore is 3.43 in (87 mm) and stroke is 3.27 in (83 mm). In 300ZX form, it prepared 160 hp (120 kW) . On April 1987 the "W" series VG30 had been released, adding 5 horsepower but leaving torque unchanged. In 1989, the Maxima received the 160 hp (120 kW) review, but also utilized a variable intake plenum improving torque to 182 lb) @3200 rpm.
