The engine's service weight is 222 kg (489 lb). The 3UR-FE as seen in a Tundra. For a time, Toyota offered an available bolt-on Toyota Racing Development Eaton Corporation Twin Vortices Series roots-type supercharger kit for the Tundra and Sequoia which bumps power up to 504 hp (376 kW; 511 PS) and 550 lb⋅ft (746 N⋅m) of torque. The ...
These included the shared use of a 3.4L V6 engine which was the top-of-the-line engine in both the Tacoma and T100. The V6 engine would serve as the base engine for the Tundra, while a second engine was added, a 4.7L V8, the first V8 for a Toyota pickup. Model code XK30 denotes rear-wheel drive models, while XK40 is for four-wheel drives. [1]
All the A17 engines are almost identical to the 4EE2 base engine, the main changes are in the ECU, control software, camshaft position sensing wheel, added sensors (exhaust temperature), injector upgrades and modifications of the engine cover, resulting in shifting oil cap position. 79 mm (3.1 in) 86 mm (3.4 in) 1,686 cc (102.9 cu in)
The 4.0 L (3,969 cc; 242.2 cu in) all-alloy 1UZ-FE debuted in 1989 in the first generation Lexus LS 400/Toyota Celsior and the engine was progressively released across a number of other models in the Toyota/Lexus range. The engine is oversquare by design, with a bore and stroke size of 87.5 mm × 82.5 mm (3.44 in × 3.25 in). [2]
Other manufacturers may modify the engine after it has left the Toyota factory but the engine still keeps the original Toyota designation. For example, Lotus added a supercharger to the 2ZZ-GE in some versions of the Lotus Elise and Exige, but the engine is still labelled 2ZZ-GE, not 2ZZ-GZE. Examples: 3S-GTE 3S – Third model in the S engine ...
The Toyota GR engine family is a gasoline, open-deck, piston V6 engine series. The GR series has a 60° die-cast aluminium block and aluminium DOHC cylinder heads.This engine series also features 4 valves per cylinder, forged steel connecting rods and crankshaft, one-piece cast camshafts, a timing chain, [1] and a cast aluminium lower intake manifold.
A hemispherical head ("hemi-head") gives an efficient combustion chamber with minimal heat loss to the head, and allows for two large valves.However, a hemi-head usually allows no more than two valves per cylinder due to the difficulty in arranging the valve gear for four valves at diverging angles, and these large valves are necessarily heavier than those in a multi-valve engine of similar ...
Starting around 1925 engine blocks and cylinder heads were now developed at each brand but were cast at Saginaw Metal Casting Operations. [3] In the mid-1960s, there were 8 separate families of GM V8 engines on sale in the USA. [4] [1] By the 1970s, GM began to see problems with their approach.
