Well, from Wikipedia:
"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 190 hp (142 kW) at 4800 rpm with 220 lb·ft (298 Nm) of torque at 3600 rpm. It has a cast iron engine block, and aluminum DOHC cylinder heads designed by Yamaha Motor Company. It uses sequential multi-port fuel injection, has 4 valves per cylinder with bucket tappets and features large cast connecting rods, a one-piece cast camshaft, and a cast aluminum intake manifold. It also features an oil cooler and coil-on-plug ignition."
