1VZ-FE


The 1VZ-FE is a 2.0 L (1992 cc) version. Bore is 78 mm (3.07 in) and stroke is 69.5 mm (2.7 in). Output is 136 hp (101 kW) at 6000 rpm and 128 ftlbf (173 Nm) at 4600 rpm.


Applications: JDM

2VZ-FE


The 2VZ-FE is a 2.5 L (2507 cc) version. Bore is 87.5 mm (3.4 in) and stroke is 69.5 mm (2.7 in). Output is 159 hp (118 kW) at 5800 rpm and 159 ftlbf (215 Nm) at 4600 rpm.


Applications:


19881991 Toyota Camry


19881991 Lexus ES 250


3VZ-E


The 3VZ-E is a 3.0 L (2958 cc) version. Bore remains at 87.5 mm (3.4 in) but stroke is pushed to 82.0 mm (3.2 in). At introduction output was specified as 145 hp (108 kW) then later bumped to 150 hp (112 kW) at 4800 rpm with 180 ftlbf (244 Nm) of torque at 3400 rpm. Despite sharing an engine family designation the 3VZ-E and 3VZ-FE have few parts in common.


Applications:


19881995 Toyota 4Runner


19881995 Toyota Pickup


19931995 Toyota T100


3VZ-FE


The basic design is a revised 3VZ-E iron block truck motor, mated with aluminum DOHC 24-valve heads and Toyota's most advanced OBD-I control system. The upper aluminum intake plenum is of the split chamber design with Toyota's ACIS variable intake system feeding three sets of runners for both heads.


Because of the truck roots, the 3VZ-FE happens to be a physically tall motor. To make the engine fit, 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 VZ engine family. The few parts shared with the 3VZ-E that are interchangeable are the main bearings, and little else. Also cams can be interchanged between the 5VZ-FE and 3VZ-FE heads(the 5VZ-FE cams have more low end torque). In a surprising twist, no electronics from other Toyota (Denso) parts are swappable.


The 3VZ-FE is a smooth running engine that was used on the Camry platform between 1992 and 1997.5 depending on the market: North America saw the engine only in 1992 and 1993 while Australia and New Zealand had it from 1992 through 1996. The engine was available in some parts of Asia and in the JDM Toyota Windom through 1997.5.


The 19921993 engine has 185 hp (138 kW) at 5800 rpm and 189 ftlbf (256 Nm) at 4600 rpm. 1994+ have 200 hp (149 kW) at 5800 rpm and 204 ftlbf (277 Nm) at 4600 rpm. There is no mechanical difference in the engine. In an embarrassing move, Toyota inadvertently created an engine competing with the more performance oriented 7M-GE (200 hp) and 2JZ-GE (225 hp) installed in sportier, more luxurious cars of the time. Because of this; the stock ignition timing and fueling was noticeably detuned. The power spread of the 3VZ-FE is wide, having 100% torque between 25004600 rpm, with power trailing off by 6000 rpm. Stock redline is 6600 rpm, and the ECU's fuel/ignition cut is 7200 rpm.


Though harder to find in good used condition in North America (unless imported), the 3VZ-FE is a fairly common V6 in most parts of the world, after having a good lifespan in popular models. They are cheap, simple, have few problems, and have become a semi-popular subject for engine swaps (particularly into the mid-engine MR2).


The 3VZ-FE has a larger forged steel crankshaft and large cast rods. They can handle double the stock power output, although forged pistons & rods are recommended. A few nitrous and turbocharged examples match or exceed 450 hp (336 kW) on both the stock engine and engine management with a piggyback chip controlling fuel & ignition.


Applications:


19921993 Toyota Camry


19911996 Toyota Windom/Lexus ES300


4VZ-FE


The 4VZ-FE is a 2.5 L (2496 cc) version. Bore is 87.5 mm (3.4 in) and stroke is ever so slightly lower from the 2VZ-FE at 69.2 mm (2.7 in). Output is 173 hp (129 kW) at 6000 rpm. Compression ratio of this engine was raised from 9.0:1 to 9.6:1. In production from 1992 until 1996, it was built to replace the 2VZ-FE as Toyota's 2.5 L V6. Engine was only sold with JDM vehicles.


Applications: JDM


19921996 JDM Toyota Camry Prominent


19931996 Toyota Windom VCV11


5VZ-FE


The 5VZ-FE is a 3.4 L (3378 cc) engine. Bore is up to 93.5 mm (3.7 in) and stroke is 82.0 mm (3.2 in). Output is 190 hp (142 kW) at 4800 rpm with 220 ftlbf (298 Nm) of torque at 3600 rpm. It has a cast iron engine block and aluminum DOHC cylinder heads. It uses MFI fuel injection, has 4 valves per cylinder with bucket tappets and features large cast connecting rods, a one-piece cast camshaft, and a cast aluminum intake manifold.


The 5VZ-FE is a robust engine, as a handful of built versions exceed 900 hp (670 kW), and some stock engines can produce 450 hp (336 kW) or more with forced induction. This has become a popular engine to consider when doing engine swaps with the availability of the 3.4 L bolt-on TRD supercharger kit and custom turbocharger setups.
