Toyota 3UZ-FE Engine Specifications
The Toyota 3UZ-FE is a 3UZ family V-type four-stroke eight-cylinder direct injection naturally aspirated gasoline engine produced by Toyota Motor Corporation.
This engine has aluminum cylinder block and aluminum cylinder head. The development of the
engine began in the late 2000. This engine was equipped with VVT-i phase
shifters on the intake shafts and the ACIS system.
The Toyota 3UZ-FE has aluminum cylinder block with increased bore size up to
91.0 mm while the stroke wasn't changed (82.5 mm). The new block had same 90
degrees 'V' angle, 21 mm cylinder bank offset, and 105.5 mm bore pitch. The new
cast-iron cylinder liners are thinner by 0.5 mm (1.5 mm instead of 2 mm). The
thinner sleeves/liners are lighter, provide better cooling, but at the same time
losing strength. For improving rigidity, the thickness of the cylinder walls was
increased by 1 mm (from 5.5 mm to 6.5 mm). Also, engineers optimized the water
passage shape between the bores. This engine was equipped with a forged steel
crankshaft (fully balanced with five main journals and eight counterweights),
forged steel connecting rods, lightweight aluminum pistons with steel struts and
floating type piston pins. The engine pistons are not only increased in diameter
but also have raised the position of the piston rings.
Engine code identification:
