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 (247 Nm). Bore is 3.43 in (87 mm) and stroke is 3.27 in (83 mm). In 300ZX form, it prepared 160 hp (120 kW) and 173 lbft (235 Nm). 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 lbft (247 Nm) @3200 rpm.

It was utilized in the following cars:

1984–1989 Nissan 300ZX/Nissan Fairlady Z (160 hp/165 hp) 9.0:1 compression ratio for NA

About the Nissan VG30E Engine

The KA engines were a show of inline-4 four-stroke gasoline piston engines produced by Nissan, which were granted in 2.0 L and 2.4 L versions. The engines blocks were made of cast-iron, while the cylinder heads were made of aluminum.Despite their big capacity, this motor was not equipped with balance shafts.After utilized in the passenger cars both versions of the KA24 used a crank girdle, as opposed to individual caps. In the Nissan Hardbody and Frontier applications a crank girdle was not used.The KA24E was a SOHC12-valve engine produced from July 1988 through January 1997. It uses SEFI fuel injection, and features forged steel connecting rods, an internally balanced forged steel crankshaft, and a cast aluminum intake manifold.
