Toyota VZ engine
The Toyota VZ engine family is a series of V6 gasoline piston engines ranging from 2.0 to 3.4 L (1,992 to 3,378 cc) in displacement and both SOHC and DOHC configurations. It was the first V6 engine made by Toyota.
Developed in response to Nissan's VG engine series (which was one of the first mass-produced Japanese 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.
This series was phased out in several markets and was replaced by variants of the MZ and GR series of V6 engines.
The 1VZ-FE is a 2.0 L (1,992 cc) version, produced from 1987 to 1993. Bore and stroke is 78 mm × 69.5 mm (3.07 in × 2.74 in). Output is 103 kW (138 hp; 140 PS) at 6000 rpm and 174 N⋅m (128 lb⋅ft) at 4600 rpm. It uses a DOHC layout with a cast iron block and an aluminium 24 valve head.
To compensate for the engine's use in FWD configurations, this engine was tilted close to the firewall (approximately ~15 degrees) so that it can fit satisfactorily in FWD cars. This makes repairing the engines a more complicated task because access to the other three cylinder banks and spark plugs requires removing the intake plenum and manifold first in order to access them. This trait is shared across most DOHC variants of the VZ family as well as all other V6 engines made by Toyota that are used in FWD configurations.
Applications:
The 2VZ-FE is a 2.5 L (2,507 cc) version, produced from 1987 to 1992. Bore and stroke is 87.5 mm × 69.5 mm (3.44 in × 2.74 in) and the compression ratio is 9.0:1. Output as fitted to the North American Lexus ES250 is 116 kW (156 hp; 158 PS) at 5600 rpm and 217 N⋅m (160 lb⋅ft) 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.
