The engine is equipped with a Hitachi sequential electronic fuel injection system, an ignition control system, and an EGR system. A cylinder bore of 89 mm (3.5 inches) and a piston stroke of 96 mm (3.78 inches) give the engine a total of 2389 cc of displacement. The compression ratio is 8.6: 1 or 9.1: 1 for the early 1989 Nissan 240SX. The Nissan KA24E engine produced 143 PS (105 kW; 140 HP) at 5,600 rpm of horsepower and 206 Nm (21.0 kgm; 152.0 ftlb) at 4,400 rpm of torque. The engine code breakdown is as follows:

  • KA – Engine family
  • 24 – 2.4 liter displacement
  • None – SOHC
  • me – Multi-point fuel injection
