Is it Possible

[stanno]

I currently own a gen2 sv21... i'm very interested in upgrading to the camry prominent equipped with the 4vz... but doing some research on toyodiy.com i see there were no 5spd models in the 4vz (vzv32/33) equipped models... only for the ones with the 1vz (vzv30/31) ... is it possible to convert the 4vz model prominent from automatic to manual using the 5spd from the 1vz camry prominent or 2vz (vzv21) camry le 5spd box... ? In other words... will the automatic 4vz ecu function with the 5spd mated...?

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

* 1992–1996 JDM Toyota Camry Prominent
* 1993–1996 Toyota Windom VCV11

now what you want is the 3vz-fe

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 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 noticeably 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 450 hp (336 kW) on both the stock engine and engine management with a piggyback chip controlling fuel & ignition.

Applications:

* 1992–1993 Toyota Camry
* 1991–1996 Toyota Windom/Lexus ES300

what you need is a full ecu swap and custom wiring and mounts, you would have less trouble with a 3s-gte

No doubt the 3vz is the ultimate vz badboy for a camry... but... i wanted a 4vz prominent for two specific reasons...

Reason#1... Our govt here recently implemented some heavy taxing on vehicle registration for luxury vehicles sporting engines 3L and over.... and the increase is ridiculous ... really can't afford it sadly... & #2...the 4vz is the only v6 option which is 500cc less (give or take) than the 3.0 mark... & It's the stock engine which would also mean i could avoid engine swaps etc and just mate a 5spd and call it a day ... So... can't the stock 4vz run a 5spd...?

this is a hard thing for me because the 4vz never made it state side.

yes you can mate a e153 (early years have a wider than newer e153 but wider than the s54)

what you have to do is ground the control solenoids using high wattage resistors.

all vz series engine have the same bell housing, they also share the same bell housing with the s,mz,a,az series engine.

do a search on here for manual swaps they should cover about what parts you will need to get eveything working.

also the 2mz is a 2.5l

Whoa... didn't know that so many other family engines shared the same bell housing... An especially shocker is the A series engines... altho... the 4A-GZE did carry an E-series transmission (E58)... So i guess this makes sense... will do a search ...

Thanks...

i was hoping to answer this...but yes a 5spd from a 3vz-fe or a 1mz-fe will bolt onto that engine. i believe the prominent is like the es300/250 i've looked at alot of specs on that car. the shifter should be the same as a camry as well as the cables. the subframe will also give you some insight if it is identicle to a state side camry.
