The Toyota VZ engine family is a series of V6 gasoline piston engines ranging from in displacement and both SOHC and DOHC configurations. It was Toyota's first V6 engine, being made as a response to Nissan’s VG engine, one of Japan’s first mass-produced V6 engines. The VZ family uses a 60° V-angle design, and introduced many changes for Toyota, including various EFI, ECU, and engine improvements from generation to generation. The low angle DOHC and SOHC cylinder heads excel in low-mid torque and power, making the VZ series well-suited for various uses in cars, trucks, and SUVs. The blocks are all strongly made using cast iron with large interconnected main bearing cradles and two bolt main bearing caps. Cylinder heads are made from aluminium. Forged steel crankshafts, and cast iron main bearing support girdles became standard with the 3VZ-FE. Piston and ring construction are typical parts, with rods varying between large and very large for stock V6 production engines. 1VZ-FE The 1VZ-FE is a version, produced from 1987 to 1993. Bore and stroke is . Output is at 6000 rpm and at 4600 rpm. It uses a DOHC layout with a cast iron block and an aluminium 24 valve head. Applications: 1988–1991 Toyota Camry Prominent (Japan only) 1988–1991 Toyota Vista (Japan only) 2VZ-FE The 2VZ-FE is a version, produced from 1987 to 1991. Bore and stroke is and the compression ratio is 9.0:1. Output as fitted to the North American Lexus ES250 is at 5,600 rpm and at 4400 rpm with redline limit of 6800 rpm. It uses a DOHC layout with a cast iron block and an aluminium 24 valve head. Applications: 1988–1991 Toyota Camry 1989–1991 Lexus ES 250 3VZ-E The 3VZ-E is a version, produced from 1987 to 1995. Bore remains at but stroke is pushed to . At introduction output was specified as then later bumped to at 4800 rpm with of torque at 3400 rpm. It uses an SOHC layout with a cast iron block and an aluminium 12 valve head. Despite sharing an engine family designation with the 3VZ-FE, the 3VZ-E and 3VZ-FE only have few parts in common. Applications: 1988–1995 Toyota 4Runner 1988–1995 Toyota Pickup 1988–1995 Toyota Hilux 1992–1994 Toyota T100 3VZ-FE The 3VZ-FE is a version, produced from 1992 to 1997. It is a revised variant of the 3VZ-E, mated with aluminium DOHC 24 valve heads. It retains the same bore and stroke,
