Toyota 5VZ-FE engine reliability, problems and repair

In 1995, specifically for the off-road Toyota models, 5VZ-FE engine has been released. It has been developed on the basis of its predecessor – 3VZ-E – though, it has some differences. 5VZ engine cylinder block is configured 60° V6, just like the 3VZ-E, but the bore diameter has been increased up to 93.5mm. The engine has new pistons; the compression ratio is 9.6. This way, the engine has got the displacement of 3.4L.

5VZ uses more modern cylinder heads with two camshafts. They are similar to those of 3VZ-FE but they have some differences. 5VZ uses camshafts that produce maximum torque at low-mid engine rpm. This engine is provided with an oil cooler and its engine coolant system fan has been improved. To this, its timing belt was renewed. The intake manifold with long length runners also produces maximum torque at low-mid engine rpm. In comparison with the 3VZ-E, 5VZ-FE features the modified exhaust manifold construction and a slightly changed ignition system. The stock size of fuel injectors is 276 cc/min. Firing order – 1-2-3-4-5-6. 5VZ features sequential multiport fuel injection (SFI), just like 1MZ.
All this secures lots of torque at low-mid engine rpm that is perfect for the off roaders, pickup trucks, and commercial carriers.
If this is not enough for you, specifically for the 5VZ-FE, TRD company has been releasing the supercharger kits, which increase the engine power up to 245 HP and the torque – up to 360Nm.
The production of 5VZ has been stopped in 2004. Instead of it, 1GR-FE engines are used.

Toyota 5VZ engine problems and malfunctions

The main troubles of 5VZ-FE are the same as those of 3-liter 3VZ, though the problems of overheating and the troubles with cylinder head gaskets occur much less often. This engine has longer life expectancy, especially if you use the highest quality engine oil. You can learn more about the possible problems HERE.

5VZ Supercharger

This engine is designed for the off-road vehicles, so you do not need to buy performance parts to build high rev naturally aspirated race engine, this would be a bad idea. If you want more power, you may buy a TRD supercharger kit that uses Eaton M62 supercharger. TRD supercharger kit of the second generation (black) is the best choice, as its lifespan is higher. Its price is quite high, so it may be better to buy a used kit. However, this is not enough and you may need some more performance upgrades.
If you have the 5VZ with EGR valve, then you are better to use the fuel injectors from the 2JZ-GE engine (315 cc). If your engine does not feature EGR valve, then you need the 5VFZE 7th injector kit. It is also desirable to buy Denso IK22 iridium spark plugs and Walbro 190 fuel pump. Install this kit to the stock internals and at the maximum boost pressure of 7 psi (0.5 bar), you will get about 250-260 horsepower. This way, you can achieve a huge raise of the torque at all range.
Instead of stock 2.37’’ pulley, you may use 2.2″ size pulley. This will increase the maximum boost up to 8.5 psi (0.6 bar), and you will get about 280 horsepower. But this way, you need to use gasoline with the higher octane number. Buy a cat-back performance exhaust system, and this will add about 10 HP.
If you want more than 300 horsepower, then buy 2.1″ size pulley (or even 2″), this will increase boost up to 11 psi (0.75 bar). However, your stock internals might not withstand such performance upgrades. You’ll need to buy forged pistons to lower the compression ratio or a water/methanol injection kit.
There is no point in porting or 5VZ-FE turbo constructing, as it is too expensive. It would be better to buy a more powerful car.
