Toyota 2JZ-GTE Engine: Specifications and technical data (2024)

Engine code identification:

2 – 2-nd generation engine
JZ – Engine family
G – Performance wide-angle DOHC
T – Turobchagered
E – Multi-Point Fuel Injection

The Toyota 2JZ-GTE engine has a cast-iron cylinder block, bore is 86.0 mm (3.39 in) and stroke is 86.0 mm (3.39 in). Compression ratio rating is 8.5:1.

The cylinder block, a monoblock specially cast structure, employs the seven bearing support system. The crankshaft has seven journals and twelve counterweights; both pins and journals are induction-hardened. The pistons are special aluminum casting. Each piston is fitted with two compression rings and a single oil ring. The surface of the top compression ring is chromium plated. The 2JZ-GTE has recessed piston tops then 2JZ-GE, it gives a lower compression ratio.

The cylinder head is made of a light, strong aluminum alloy with good cooling efficiency. Camshafts are made of specially cast steel and are driven by a timing belt. The 2JZ-GTE engine is equipped with four valves per cylinder: two intake valves and two exhaust valves.

Valves are made of heat-resistant steel and have an included valve angle of 45°. 1-st generation of the 2JZ-GTE engine for JDM has an intake duration of 224&deg, and exhaust duration of 236°, intake valve lift is 7.8 mm (0.31 in) and exhaust valve lift is 8.4 mm (0.33 in). For North American and European markets intake duration is 233&deg and exhaust duration of 236°, intake valve lift is 8.25 mm (0.32 in) and exhaust valve lift is 8.4 mm (0.33 in).

The Toyota JZ engines are not equipped with hydraulic lifters, so special valve shims are used to adjust the valve clearance.

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).
