Toyota 2JZ-GE Engine Specs
The Toyota 2JZ-GE is a 3.0 liter 182.89 cu-in (2,997 cc) straight-six, four-stroke cycle natural aspirated gasoline engine from the Toyota JZ-family. The Toyota Motor Corporation made the engine at the Tahara Plant (Aichi, Tahara, Japan) in 1991.
The Toyota 2JZ-GE VVTi engine delivered from 215 PS (158 kW; 212 HP) at 5,800 rpm to 230 PS (169 kW; 227 HP) at 6,000 rpm of HP and from 294 Nm (30.0 kg·m; 217.0 ft·lb) at 3,800 rpm to 304 Nm (31.0 kg·m; 224.3 ft·lb) at 4,000 rpm of maximum torque. Bore and stroke are 86.0 mm (3.39 in) and 86.0 mm (3.39 in), respectively.
The Toyota 2JZ-GE engine has been fitted with an L-type electronically-controlled, multiport sequential fuel injection (SFI) system and VVT-i (Variable Valve Timing with intelligence) since 1996.
The Toyota 2JZ-GE engine features a cast-iron block, an aluminum cylinder head with dual belt-driven overhead camshafts, and four valves per cylinder (24 in total).
The Toyota 2JZ-GE engine used a conventional throttle body whereby the part of the accelerator pedal effort determines the throttle valve opening. The throttle body and Idle Air Control (IAC) are integrated into a single unit.
The VVT-i version used the ETCS-i system (Electronic Throttle Control System-intelligent). For this system, the ECU (Engine Control Unit) calculated the optimal throttle valve opening according to driving conditions and used a control motor for the throttle valve opening.
The breakdown of the Toyota 2JZ-GE engine code is as follows:
- 2 – 2-nd generation engine
- JZ – Engine family
- G – Performance wide-angle DOHC
- E – Multi-Point Fuel Injection

Valve clearance adjustment data
Calculate the thickness of new adjusting valve lifter so valve clearance comes within specified values.
R = Thickness of removed valve lifter
N = Thickness of new valve lifter
M = Measured valve clearance
Intake:
N = R + [M – 0.20 mm (0.008 in)]
Exhaust:
N = R + [M – 0.30 mm (0.012 in)]
Valve lifters are available in 17 sizes range from 2.50 mm (0.0984 in) to 3.30 mm (0.1181 in), in steps of 0.05 mm (0.0020 in).
Example (intake valve):
R = 2.90 mm
M = 0.40 mm
N = 2.90 + (0.40 – 0.20) = 3.10 mm, so we need a valve shim with thickness of 3.10 mm (0.1220 in).
