Toyota's 4.7-liter V8 engine, a prominent member of the UZ family, is designed for use in large trucks and SUVs, hence its substantial displacement, low revolutions, and high torque output. Unlike the 1UZ-FE and 3UZ-FE engines, which feature aluminum cylinder blocks, the 2UZ-FE engine boasts a cast iron block—a more durable and cost-effective material. This choice, however, significantly increases the engine's weight. Aside from the increased bore and stroke, the 2UZ engine block shares the same design and dimensions, including a 90-degree 'V' angle, a 21-mm cylinder bank offset, and a bore pitch of 105.5 mm. The engine is equipped with a steel crankshaft featuring eight counterweights and five main journals, as opposed to the six journals of the 1UZ crankshaft, along with forged and sintered connecting rods, and aluminum alloy pistons whose skirts are tin-plated to reduce friction.

Atop the cylinder bank, aluminum heads are mounted. Each head houses intake and exhaust camshafts, along with four valves per cylinder. The engine employs the same camshaft rotation method: intake camshafts are driven by a timing belt, while exhaust camshafts are gear-driven by the intake camshafts. The valvetrain design of the 2UZ mirrors that of the 1UZ. The intake and exhaust valves are positioned on opposite sides at an angle of 21.55 degrees. The intake valves measure 34.5 mm in diameter, and the exhaust valves are 29.0 mm in diameter, matching the later 1UZ-FE version with VVT-i. The engine features steel solid valve lifters, necessitating periodic valve clearance adjustments.

The initial models of the 2UZ-FE featured a straightforward aluminum intake manifold with an elongated port. This engine incorporated a heat-barrier gasket sandwiched between two metal gaskets, placed between the intake manifold and each cylinder head. Early in its production, the engine was equipped with a standard throttle body, with Toyota's electronically controlled throttle body system (ETCS-i) being introduced in late 2002. Right from its inception, the 2UZ-FE engine utilized sequential multiport fuel injection (SFI). This system employed eight four-hole fuel injectors (one per cylinder), a mass air flow meter, and a pair of air-fuel ratio sensors. The engine also featured Toyota's The Direct Ignition System (DIS) features individual ignition coils for each of the eight cylinders and iridium spark plugs. It also includes two knock sensors and Electronic Spark Advance technology, which regulate and fine-tune the ignition timing to prevent engine knock.
