The 3VZ-FE engine has 6 cylinders in a V arrangement with a 60 ° rake angle The 3VZ-FE features a cast iron cylinder block with a four bearing crankshaft and two aluminum cylinder heads with two camshafts (DOHC) and four valves per cylinder (24 total). The Toyota 3VZ-FE engine is equipped with the SFI (Sequential Multiport Fuel Injection) system and an electronic ignition system with mechanical distributor.
A cylinder bore of 87.5 mm (3.44 inches) and a piston stroke of 82.0 mm (3.23 inches) give the 3VZ-FE engine a total of 2,958 cc of displacement. The compression ratio is 9.6: 1. The Toyota 3VZ-FE engine produced from 185 hp (136 kW, 182 hp) at 5800 rpm to 200 hp (147 kW, 197 hp) at 5800 rpm of maximum power and from 256 N · m (26.1 kg · m, 188.7 ft · Lb) at 4,600 rpm to 275 N · m (28.0 kg · m, 202.7 ft · lb) at 4,600 rpm of maximum torque.

The 3VZ-FE engine has 6 V-cylinders at a 60 ° rake angle. The firing order for this engine is 1–2–3–4–5–6. The crankshaft is supported by four bearings within the crankcase. These bearings are made of lead copper alloy. The crankshaft is integrated with semi 9 counterweights to maintain balance. Oil holes are positioned in the center of the crankshaft to supply oil to connecting rods, pistons, and other components. The diameter of the main crankshaft journal is 64,000 mm (2.52 in) and the diameter of the crankpin is 55,000 mm (2.16 in)
The pistons are made of high-temperature resistant aluminum alloy and the vacuum is built into the piston head to avoid interference with the valves. The piston pins are of the full float type, with the pins not attached to either the piston boss or the connecting rods.
Each piston is equipped with two compressions and an oil control ring. The upper compression ring is made of steel and the second compression ring is made of cast iron. The oil ring is made of a combination of steel and stainless steel. The outside diameter of each piston ring is slightly larger than the diameter of the piston and the flexibility of the rings allows them to engage the cylinder walls when mounted on the piston.
The bore is 87.5 mm (3.44 inches) and the stroke is 82.0 mm (3.23 inches). The compression ratio is 9.6: 1.
