Hello

My name is pd4x4 and I am new here
This information is available on Wikipedia by
clicking here, but I thought it would be cool as my first opening post on this awesome forum to mirror the info here so the Marlin Crawler Community doesn't have to leave this great forum to learn about the Toyota UZ V8 engine
1UZ-FEThe 4.0 L (3,968 cc/242.1 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 size of 87.5 mm (3.44 in) and stroke of 82.5 mm (3.25 in).[1] It has proved to be a strong, reliable and smooth powerplant with features such as 6-bolt main bearings and belt-driven quad-camshafts. The water pump is also driven by the cam belt. The connecting rods and crankshaft are constructed of steel. The pistons are hypereutectic.
Its resemblance to a race engine platform (6 bolt cross mains and over square configuration) was confirmed in 2007 by David Currier (in an interview with v-eight.com), vice president of TRD USA, stating that the 1UZ platform was based on CART/IRL engine design. It was planned to be used on GT500 vehicles, however its subsequent use in the Daytona Prototype use was not planned.
In its standard, original trim with 10:1 compression, power output is 191 kW (256 hp), torque of 353 N·m (260 ft·lbf).[1]
Engine and manual gearbox, because the factory, all 1UZ for automatic and manual production never ever, we put him on the modified suv, and to change manually, it brings the docking, 1UZ problem of the gearbox, basically have the following a few:
3VZ 5VZ, 1P, Jeep4.0, gearbox, namely the engine G58 Toyota W55, W56, R151F, R154, R150, series gearbox
The engine was slightly revised in 1995 with lighter connecting rods and pistons and an increased compression ratio to 10.4:1 resulting in peak power of 195 kW (261 hp) and torque of 363 N·m (268 lb·ft).
In 1997, Toyota's VVT-i variable valve timing technology was introduced along with a further CR increase to 10.5:1,[1] bumping power and torque to 216 kW (290 hp) and 407 N·m (300 ft·lbf). In the GS400 application, output was rated at 300 hp and 310 ft-lb of torque.
The 1UZ-FE was voted to the Ward's 10 Best Engines list for 1998 through 2000.[2][3][4]
Applications:
1989–2000 Lexus LS 400/Toyota Celsior
1990–2002 Toyota Crown/Toyota Crown Majesta
1991–2000 Lexus SC 400/Toyota Soarer
1992–2000 Lexus GS 400/Toyota Aristo
Toyota MR2 Le Mans Car
2UZ-FEThe 2UZ-FE was a 4.7 L (4,664 cc/284.6 cu in) cast iron block version built in Tahara, Aichi, Japan and at Toyota Motor Manufacturing Alabama. Designed for low-reving, high-torque SUV applications, its bore is 94 mm (3.7 in) and stroke is 84 mm (3.3 in).[1] Output varies by implementation, but one VVT-i variant produces 202 kW (271 hp) at 4800 rpm with 427 N·m (315 ft·lbf) of torque at 3400 rpm. JDM versions produce 173 kW (232 hp) at 4800 rpm and 422 N·m (311 ft·lbf) at 3600 rpm, while Australian models produce 170 kW (230 hp) at 4800 rpm and 410 N·m (300 ft·lbf) at 3600 rpm.[1]
Like the 1UZ-FE it has aluminum DOHC cylinder heads, MFI fuel injection, 4 valves per cylinder with bucket tappets, one-piece cast camshafts, and a cast aluminum intake manifold. For 2010, it was replaced by the 1UR-FE in all applications.
Applications:
2003–2004 Lexus GX 470
1998–2005 Lexus LX 470
1998–2005 Toyota Land Cruiser
2003–2004 Toyota 4Runner
2000–2004 Toyota Tundra
2001–2004 Toyota Sequoia
Toyota Racing Development offered a bolt-on supercharger kit for the 2000-2003 Tundra and the 2003 GX 470
Another 2UZ-FE variation adds VVT-i and electronic throttle control.
Applications:
2005–2009 Lexus GX 470
2006–2007 Lexus LX 470
2005–2009 Toyota 4Runner
2006–2007 Toyota Land Cruiser
2005–2009 Toyota Tundra
2005–2009 Toyota Sequoia
3UZ-FEThe 3UZ-FE, is a 4.3 L (4,292 cc/261.9 cu in) version built in Japan. Bore is 91 mm (3.6 in) [1] and stroke is 82.5 mm (3.25 in). Output is 216 to 224 kW (290 to 300 hp) at 5600 rpm with 441 N·m (325 ft·lbf) of torque at 3400 rpm. It has an aluminum engine block and aluminum DOHC cylinder heads. It uses SEFI fuel injection, has 4 valves per cylinder with VVT-i. It replaced the 3S-GTE as the engine that powers Toyota's 500hp (370kw) Super GT race cars. A redesigned 5.0 L version was used in the Grand American Road Racing (Grand Am) Series. [7] In 2003, the engine was linked to a six-speed automatic in applications with improved fuel efficiency
Applications:
Lexus LS 430
Lexus GS 430
Lexus SC 430/Toyota Soarer
Toyota Crown Majesta
Super GT
Toyota Supra GT500 Race Car
Lexus SC 430 GT500 Race Car
In 1997, the US Federal Aviation Administration granted production certification for the FV2400-2TC, a twin-turbocharged airplane powerplant based on the UZ series Lexus engine.[8] The 360 hp (270 kW) FV2400 was developed in partnership with Hamilton Standard, which provided the digital engine-control system.[8] The goal was to produce a four-seat propeller aircraft.[9]
In 1998, an marine derivative of the UZ powerplant was produced for boating applications. The 4.0 L VT300i engine, producing 300 hp (220 kW) at 6000 rpm and 310 ft·lbf (420 N·m) at 4200 rpm, used the same block as the UZ engine on the Lexus SC 400, GS 400, and LS 400.[10] The marine engine was used on the Toyota Epic waterski boat.[
Japanese auto manufacturers aren’t renowned for their V8s but the Toyota UZ-series bent-eight most surely be one of the sweetest on the planet. A visit to any large Japanese import wrecker will also reveal that these engines are cheap and plentiful – the ideal engine for a conversion
Early UZ Engines
The first in the family of UZ-series engines is the 4-litre 1UZ-FE which was introduced in the late 1989 Japanese Toyota Celsior (aka Lexus LS400).
The all-alloy 1UZ-FE uses over-square bore/stroke dimensions (87.5 x 82.5mm) to achieve a total displacement of 3968cc. The bullet-proof bottom-end uses a steel crank with six bolt main bearing caps and the compression ratio is set to a relatively high 10:1. As a result, premium unleaded fuel is recommended though the engine does feature twin knock sensors. The 1UZ-FE draws air through a pair of DOHC, four-valve-per-cylinder heads and a multi-point injection system with a fixed length/volume induction system. Most early 1UZ-FEs are also equipped with electronic traction control which uses a secondary throttle valve.
Japanese versions are rated at 191kW at 5400 rpm together with 353Nm at 4600 rpm, while Australian delivered versions (from early 1990) make 1kW and 3Nm less. It is claimed that 90 percent of peak torque is spread from 2000 to 5600 rpm but, curiously, it doesn’t feel that way – the engine seems to come alive at around 4000 rpm.
Note that all UZ-series V8s are mated to an automatic transmission – there has never been a Toyota V8 tied to a manual ‘box. All UZ-powered cars are also rear-wheel-drive with the exception of two vehicles – the Aristo AWD and Land Cruiser/LX470.
Below I've attached a couple 1UZ pics
WOW I REALLY LOVE THE TOYOTA UZ FAMILY OF 8-CYLINDER ENGINES!Talk to you later!
