3VZ-FE INFORMATION
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 1992-1993 engine has 185 hp (138 kW) at 5800 rpm and
189 ft·lbf (256 N·m) at 4600 rpm. 1994+ have 200 hp
(149 kW) at 5800 rpm and 204 ft·lbf (277 N·m) 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 noticibly detuned. The power spread of the 3VZ-FE is wide, having
100% torque between 2500–4600 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 450hp
(336kW) on both the stock engine and engine management with a piggyback chip
controlling fuel & ignition.
