The 2UZ-FE was a 4.7 L (4,664 cc or 284.6 cu in) version built in Tahara, Aichi, Japan and at Toyota Motor Manufacturing Alabama. Unlike its other UZ counterparts, this version uses a cast iron block to increase durability, as it was designed for low-reving, high-torque pickup and 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 lbf·ft) of torque at 3400 rpm. JDM versions produce 173 kW (232 hp) at 4800 rpm and 422 N·m (311 lbf·ft) at 3600 rpm, while Australian models produce 170 kW (230 hp) at 4800 rpm and 410 N·m (300 lbf·ft) at 3600 rpm.[1]




The 1GR-FE is the 4.0 L (3956 cc) version, designed for longitudinal mounting in RWD and 4WD pickup applications. It has a 94 mm bore and a stroke of 95 mm. Output is 236 hp (176 kW) at 5200 rpm with 266 lb·ft (361 N·m) of torque at 4000 rpm on 87 octane, and 239 hp (178 kW) at 5200 rpm with 278 lb·ft (377 N·m) at 3700 rpm on 91 octane. This engine features Toyota's VVT-i, variable valve timing system on the intake cam and a compression ratio of 10.0:1. Service weight, including fluids, is 166 kg (366 lb).

An updated version of this engine features Dual VVT-i, increasing output to 254 hp (189 kW) and 270 lb·ft (366 N·m) on 87 octane and 285 hp (213 kW) and 289 lb·ft (392 N·m) on 91 octane. Inside, the 1GR uses a "taper-squish" combustion chamber design with matching pistons to improve anti-knocking and engine performance, while also improving intake and fuel efficiency. Toyota adopted a siamese-type intake port, which reduces the surface area of the port walls and prevents fuel from adhering to such walls. This engine has special cast-iron cylinder liners cast into the block, which are a spiny type to improve adhesion between the liner and cylinder block. With these special thin liners it is impossible to bore the block. In the event of cylinder wall damage (scoring, deep protrusions, etc.), the entire cylinder block must be replaced. For increased block rigidity, the 1GR also receives a high temperature plastic insulator/protector, which fills the empty space between the outer portion of the cylinders and block material common to open deck engines. For increased cooling efficiency, the 1GR employs water passages between the bores of the engine. There are two such passages for each bank for a total of four. This reduces cylinder hot-spotting and keeps combustion chamber temperatures more uniform.


Hmmm with the weights and added tq on the cast iron block of the 4runner it could be interesting.

Edit: Never mind the V8 has another 300lbs at least over the FJ Paper loss again.
