The Toyota VZ engine family is a series of V6 gasoline piston engines ranging from 2.0L to 3.4L in displacement and both SOHC and DOHC configurations. The family introduced many changes for Toyota, including various EFI, ECU, and engine improvements from generation to generation. The VZ was Toyota's response to the Nissan VG engine. The low angle DOHC cylinder heads excel in low-mid torque and power, making the VZ 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. 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. The 2VZ-FE is a 2.5 L (2507 cc) version. Bore is 87.5 mm (3.4 in) and stroke is 69.5 mm (2.7 in) and the compression ratio is 9.0. Output is 119 kW (159 bhp) at 5800 rpm and 216 N·m (159 lb·ft) at 4600 rpm with red line limit of 6800 rpm.[WIKI]
