Toyota 3VZ-FE engine factory workshop and repair manualon PDF can be viewed using PDF reader like adobe , or foxit or nitro File size 15 Mb in 528 pages searchable Contents The basic design is a revised 3VZ-E iron-block engine, mated with aluminum DOHC 24 valve heads. It has a forged steel crankshaft and cast connecting rods. The upper intake plenum is of the split-chamber design with Toyota's ACIS variable-intake system feeding three sets of runners for both heads.Because the VZ was originally for pickup truck and SUV use, the 3VZ-FE happens to be a physically tall motor. To make the engine fit in FWD engine bays, Toyota tilted the motor towards the firewall. This "tilt" is so severe (~15 degrees) that reaching the rear bank of cylinders is nearly impossible without first removing the intake plenum. Parts-wise, the 3VZ-FE shares very little with the rest of the VZ engine family. The main bearings are shared with the 3VZ-E, but little else. Cams can also be interchanged between the 5VZ-FE and 3VZ-FE heads.The 3VZ-FE was used on the Camry platform from 1992 to May 1997 depending on the market: North America saw the engine only in 1992 and 1993, while Australia and New Zealand had it from 1992 to 1996. The engine was available in some parts of Asia in the Toyota Windom until May 1997. Following 1994, the 1MZ-FE engines replaced the 3VZ-FE in most applications. However the 3VZ-FE continued to be used in Australia until 1996, especially in the Camry. The power spread of the 3VZ-FE is wide, having close to maximum torque between 2500–4600 rpm, with power trailing off by 6000 rpm. The stock redline is 6600 rpm, and the ECU's fuel/ignition cut-off is 7200 rpm.The 1992–1993 engine is rated at 185 hp (138 kW; 188 PS) at 5800 rpm and 189 lb⋅ft (256 N⋅m) at 4600 rpm. Compression ratio is 9.6:1. The 3VZ-FE is fairly common in most parts of the world, having a long lifespan in popular models.

Toyota started the production of 3.0 liter 3VZ-FE engine in 1987 as the new engine for Toyota 4Runner. This engine was installed in other off-road Toyota models in the future. The engine is similar to its predecessor the 2VZ engine, but the more significant displacement is not the one difference.The cast iron cylinder block looks the same, but it is taller by 20 mm (the height is 223 mm). The angle between cylinders in V-shape configuration of the block is 60 deg. Inside the block, there is new forged crankshaft with nine counterweights and 82 mm stroke.The early version of this engine 3VZ-E has SOHC aluminum cylinder heads and original pistons. The compression ratio of these engines is only 9.0:1. The redeveloped version and more performance engine the 3VZ-FE was produced from 1992 to 1997. The 3VZ-FE got aluminum DOHC heads with the increased diameter of the intake valves to 34 mm from 33 mm. The engine doesn't have hydraulic lifters. The shape of intake valves also was changed. 27.3 mm is the diameter of the exhaust valves. There are numbers for adjusting valve gaps: 0.25-0.35 mm intake, 0.15-0.25 mm exhaust.3VZ camshaft specs: duration - 230 intake 230 exhaust, 12 deg overlap, 7.85 mm intake lift (or .31"), 7.6 mm exhaust lift (or .30"). Timing belt drives the intake cams. The exhaust cam is driven by intake camshaft through gear in the middle of the cylinder head. The engine has variable geometry intake manifold called ACIS by Toyota. The exhaust system also was tuned and optimized.The engine was designed to be installed with 15 deg angle to use it in many applications. The manufacturer slowly replaced 3VZ-FE engine since 1994 by 1MZ-FE, but 3VZ got new life as the 3.4 liter 5VZ-FE in 1995.
