Toyota 2JZ-GTE/GE/FSE engine reliability, problems and repair
In addition to the 1JZ,they produced the second, larger modification of the JZ called 2JZ. The
engine replaced the past Toyota 7M. The 2JZ is a simple sort of a
straight 6 cylinder motor with a hard cast iron cylinder block and 3
liter displacement. Comparing with the 1JZ, the block of cylinders
became 14 mm higher. A crankshaft with a longer piston stroke (to 86
mm.) was mounted inside it. The motor is like the 1JZ. It has got two
camshafts and 4 valves for each cylinder. The engine is equipped with an
ACIS variable length intake manifold. Since 1997 the VVTi system was
added. There are no hydraulic lifters on the motor. The valve clearance
control is needed each 60,000 miles (100,000 km) of mileage. Firing
order on the 2JZ is 1-5-3-6-2-4.
The 2JZ has a toothed timing belt. Its life span is 60,000 miles (100,000 km) of mileage.
The 2JZ (2JZ-GTE modification) is more known and famous, than the 1JZ motor and is similar to the Nissan RB26DETT
engine. The quickest and craziest Toyota Supra engines (1500-2000
horsepower) were made of the 2JZs. These cars drove ¼ mile quicker than
per 7 sec. The fans installed the 2JZ in other Toyotas, and also in Ford
Mustang, Chevrolet Corvette, Camaro, different BMW, Mazda, and so on.
The
2JZ was produced from 1991 to 2007. The following modifications were
produced: 2JZ-FSE, 2JZ-GE and 2JZ-GTE. Their specifications are given
beneath.
Toyota 2JZ engine modifications and differences
1. The 2JZ-FSE D4 modification (1999 –2007) is a sort of the 2JZ engine with a direct injection system, which
is similar to the 1JZ-FSE. It has got a compression ratio of 11.3,
capacity of 220 horsepower at 5600 rpm. and its toque is 294 Nm (216
lb•ft) at 3600 rpm.
2. The
2JZ-GE type (1991 – 2005) is a kind of the 2JZ naturally aspirated
engine. The first modification produced till 1997 had compression ratio
of 10.5, 2JZ-GE stock injectors were 250 cc. Its capacity depended on
settings and varied from 220 to 230 horsepower. When upgraded in 1997,
the 2JZ was provided with a VVTi system, 3 ignition coils, another ECU
broaching, etc. The capacity remained the same.3.
The 2JZ-GTE engine (1991 – 2004) is a sporting turbocharged 2JZ-GE
modification. The motor was improved with CT20A turbochargers,
intercooler, and the other pistons fitted to compression ratio of 8.5.
The connecting rods were borrowed from the 2JZ-GE and the injectors are
440 cc. The 2JZ-GTE camshaft specifications are as follows: duration
224/236 deg, lift 7.8/8.4 mm. Such engines developed a capacity of 280 horsepower at 5600 rpm. and had a torque of 435 Nm (320 lb•ft) at 4000 rpm.
The
2JZ-GTE modifications were designated for exporting. They were equipped
with CT12B turbocharges, other camshafts (duration 233/236 deg, 8.25
/8.4 mm lift), and 550 cc injectors. Due to those factors, the capacity
of the exported 2JZ-GTE engine was increased to 330 horsepower at 5600
rpm. with a torque of 441 Nm (325 lb•ft) at 4800 rpm.
In
1997 the 2JZ was provided with a VVTi variable valve timing system. Its
power remained the same, and its torque rose to 451 Nm (332 lb•ft) at
3600 rpm.
Toyota 2JZ engine problems and malfunctions
The 2JZ failures were similar to thoseof its younger brother, the 1JZ. Water can pour onto the spark plugs if
washed. In such a case, your 2JZ won’t start. Due to the presence of the
VVTi and idle control valve sensor, there can be problem caused by
rough idle and so on. It is HERE, where you can find out about all common problems.
The
2JZ is extremely safe and durable. If your motor has been properly
maintained and only a high quality engine oil has been used, the 2JZ
engine lifespan will comprise more than 300,000 miles (500,000 km) of
mileage.
Toyota 2JZ engine tuning
Twin Turbo 2JZ. Single Turbo
Everyone knows about the 2JZ’s tuning. Although, some basic principles are worth mentioning.It’s
no use upgrading the 2JZ-GE. You can certainly buy all the necessary
performance cams, ITB, do head porting, mount an aftermarket intake
system, headers and performance exhaust system.
When the engine has been built, it will develop not bad capacity, but
the 2JZ-GTE equipped with a simple boost-up will be more powerfull and
simpler.
You can buy a 2JZ-GE
turbokit (Garrett GTX30) with a complete set of details and bolt the
2JZ-GTE pistons on or a thick 3 mm cylinder head gasket. You can also
buy a 80 mm throttle body and adjust it on the Greddy E-Manage. As a
result, you can get about 450 horsepower.
2JZGTE Tuning guide
The simplest and most reasonable thing is a purchase of a powerful 2JZ-GTE and swap.The
boost-up is to the first step to upgrading the engine. For doing that,
you need to get a big intercooler, huge radiator, oil cooler, air
filter, Toyota Supra US (280 lph) fuel pump, and injectors. The stock
can be remained or you can buy 550 cc stock injectors. Also, you will
need a performance exhaust system 3″, ECU Mines/Blitz (or something like
that), and a boost-controller.All
the aftermarket parts allow increasing pressure in the stock
turbochargers up to 17-19 psi (1.2-1.3 bar) in order to generate 450
horsepower.
If that doesn’t suit
you, you will have to buy a 2JZ-GTE turbokit (Garrett GTX3582R), 264
deg. camshafts, Walbro 400 lph pump, 1000 cc injectors, and ECU APEX’i
Power FC. That will help generate up to 750 horsepower.
It
is dangerous to exceed that limit while dealing with the 2JZ stock
internals. Otherwise, you can face the music. For further increasing the
engine’s capacity, it would be better to acquire new forged pistons
with reinforced Carrillo connecting rods, ARP head studs; you also had
better improve the cylinder head and buy the camshafts (duration 272 –
280 deg.), as well. In addition to that, you have to get more powerful
turbokit and gain the engine’s capacity to 1000 – 1500 horsepower or
more.
