The KA24DE engine was made by Nissan and used in several models including the Nissan 240SX. Cast-iron was used to manufacture the engine block and aluminum for the cylinder heads. According to 240 Edge, the KA24DE engine is very similar to the KA24E, although it has more power and torque.
The KA24E engine has a single overhead camshaft (SOHC) and three valves per cylinder. The KA24DE has a dual overhead camshaft (DOHC) and four valves per cylinder; it also has a knock sensor, which detects and responds to engine knock. The pistons have oil injection and the spark plugs are top firing.
The displacement of the KA24DE, or volume swept by the pistons within the cylinders, is 2.4 liters.
Bore and stroke refer to the diameter measurement of the cylinder and the length of piston travel. For the KA24DE, this is 3.50 inches by 3.77 inches, respectively.
Compression ratio is the ratio of the volume of the engine's combustion chamber from largest to smallest capacity. From 1991 to 1993, the compression ratio of the KA24DE engine was 9.0-to-1. From 1994 to 1998, it was 9.5-to-1.
The KA24DE engine produces 155 horsepower at 5,600 rpm. The torque is 160 foot-pounds at 4,400 rpm. The redline (safe maximum engine speed) is 6,500 rpm.
