The Toyota 2L-T is a 2.4 L (2,446 cc, 149.3 cu·in) four cylinders, four-stroke cycle water-cooled turbocharged internal combustion diesel engine, manufactured by the Toyota Motor Corporation.
The 2L-T is a turbo version of the 2L still being produced since 1985. The 2L-T engine has a cast iron cylinder block with 92.0 mm (3.62 in) cylinder bores and a 92.0 mm (3.62 in) piston stroke. Compression ratio rating was 20:1. The motor has a cast iron cylinder head with a single overhead camshaft (SOHC) with two valves per cylinder and indirect injection design.
Later version the 2L-T II is an upgrade of the 2L-T. The cylinder bore and the piston stroke remains the same. The most significant change is that the camshaft lifts the valve directly via tappet instead of a rocker arm. The valve clearance is adjusted using shims.
The Toyota 2L-T produced from 86 PS (63 kW; 85 HP) at 4,000 rpm to 91 PS (67 kW; 90 HP) at 4,000 rpm of maximum horsepower and 188 N·m (19.2 kg·m, 138.6 ft·lb) at 2,200 rpm of maximum torque. The 2L-T II modification produced 94 PS (69 kW, 93 HP) at 4,000 rpm and 216 N·m (22 kg⋅m, 159 ft·lb) at 2,400 rpm.
The breakdown of the engine code is as follows:
- 2 – 2nd generation engine
- L – Engine family
- T – Turbocharged

Cylinder block
The cylinder block is made of cast iron. The crankshaft is supported by five bearings on the inside of the crankcase. The crankshaft bearings are made of aluminum alloy. The crankshaft is integrated with balance weights which are cast along with it for balance.
The cylinder bore is 92.0 mm (3.62 in), piston stroke is 92.0 mm (3.62 in) and compression ratio rating is 20:1.

“Nozzle opening pressure: New: 14,810-15,590 kPa (151-159 kg/cm2, 2,148-2,262 psi)
Reused: 14,220-15,200 kPa (145-155 kg/cm2, 2,062-2,205) ”
isn’t correct.
for the 2L-T engine the nozzle pressure is about 1500 PSI, as described at the Workshop manual.
