Nissan VG engine

The Nissan VG is a family of V6 engines that Nissan designed and produced between 1983 and 2004, and it was Japan's first mass-produced V6. The iron block, aluminium head 60 degree engine came in displacements from 2.0 to 3.3 L. Early versions had single overhead camshaft heads with two valves per cylinder, while later models used double overhead camshaft heads with four valves per cylinder, a slightly different block and Nissan's N-VCT variable valve timing, which gave a smoother idle and more low and mid range torque. Production blocks and heads were also used in the Nissan GTP ZX-Turbo and NPT-90 race cars, which won the IMSA GT Championship three years in a row.
