, and excelled 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.

1VZ-FE

The 1VZ-FE is a 2.0 L (1992 cc) version. Bore is 78 mm (3.07 in) and stroke is 69.5 mm (2.7 in). Output is 136 hp (101 kW) at 6000 rpm and 128 ft·lbf (173 N·m) at 4600 rpm.

3VZ-E

The 3VZ-E is a 3.0 L (2958 cc) version and is the only SOHC VZ-series motor, and the only non-DOHC V6 Toyota has ever built. Bore remains at 87.5 mm (3.4 in) but stroke is pushed to 82.0 mm (3.2 in). At introduction output was specified as 145 hp then later bumped to 150 hp (112 kW) at 4800 rpm with 180 ft·lbf (244 N·m) of torque at 3400 rpm.
Despite sharing an engine family designation the 3VZ-E and 3VZ-FE have few parts in common.

3VZ-FE

The basic design is a revised 3VZ-E iron-block motor, mated with aluminum DOHC 24 valve heads. It has a forged steel crankshaft and cast connecting rods. The upper intake plenum is of the split-chamber design with Toyota's ACIS variable-intake system feeding three sets of runners for both heads.

Because the VZ originated for truck and SUV use, the 3VZ-FE happens to be a physically tall motor. To make the engine fit in FWD engine bays, Toyota tilted the motor towards the firewall. This "tilt" is so severe (~15 degrees) that reaching the rear bank of cylinders is nearly impossible without first removing the intake plenum.

Parts-wise, the 3VZ-FE shares very little with the rest of the VZ engine family. The main bearings are shared with the 3VZ-E, but little else. Cams can also be interchanged between the 5VZ-FE and 3VZ-FE heads.

The 3VZ-FE was used on the Camry platform from 1992 to May 1997 depending on the market: North America saw the engine only in 1992 and 1993, while Australia and New Zealand had it from 1992 to 1996. The engine was available in some parts of Asia in the Toyota Windom until May 1997. Following 1994, the 1MZ-FE engines replaced the 3VZ-FE in most applications. However the 3VZ-FE continued to be used in Australia until 1996, especially in the Camry. The power spread of the 3VZ-FE is wide, having 100% torque between 2500–4600 rpm, with power trailing off by 6000 rpm. The stock redline is 6600 rpm, and the ECU's fuel/ignition cut-off is 7200 rpm.

The 1992–1993 engine is rated at 185 hp at 5800 rpm and 189 ft·lbf (256 N·m) at 4600 rpm. Compression ratio is 9.6:1.
Though harder to find in good used condition in North America (unless imported), the 3VZ-FE is fairly common in most parts of the world, having a long lifespan in popular models.

4VZ-FE

The 4VZ-FE is a 2.5 L (2496 cc) version. Bore is 87.5 mm (3.4 in) and stroke is ever so slightly lower from the 2VZ-FE at 69.2 mm (2.7 in). Output is 173 hp (129 kW) at 6000 rpm. Compression ratio of this engine was raised from 9.0:1 to 9.6:1. In production from 1992 until 1996, it was built to replace the 2VZ-FE as Toyota's 2.5 L V6. Engine was only sold with Japanese market vehicles.

5VZ-FE

The 5VZ-FE is a 3.4 L (3378 cc) engine which replaced the 3VZ-E. Bore is up to 93.5 mm (3.7 in) and stroke is 82.0 mm (3.2 in) while the compression ratio stays the same as the 3VZ-FE at 9.6:1. Output is 183 hp (142 kW) at 4800 rpm with 217 ft·lbf (298 Nm) of torque at 3600 rpm. It has a cast iron engine block and aluminum DOHC cylinder heads. It uses sequential multi-port fuel injection
