The KA engines were a series of inline-4 four-stroke gasoline piston engines manufactured by Nissan, which were offered in 2.0 L and 2.4 L versions. The engines blocks were made of cast-iron, while the cylinder heads were made of aluminum.

Despite their large capacity, this motor was not equipped with balance shafts.

When used in the passenger cars both versions of the KA24 used a crank girdle, as opposed to individual caps. In the Nissan Hardbody and Frontier applications a crank girdle was not used.

KA24E

The KA24E was a SOHC12-valve engine produced from July 1988 through January 1996. It uses SEFI fuel injection, and features forged steel connecting rods, an internally balanced forged steel crankshaft, and a cast aluminum intake manifold.

KA24DE

KA24DE Engine in a S14 240SX

The 2.4 L (2389 cc) KA24DE was used in many Nissan cars and trucks. Most KA24DEs bound for the US were built in the Mexican city of Aguascalientes, with the exceptions of the 240SX and 1994-97 Altima (rebadged Bluebird SSS), which were manufactured in Fukuoka Prefecture, Japan, and the U13 Bluebird released in Australia with FWD configuration. The KA24DE is very similar to the KA24E. The cylinder head is the only major change: the KA24E is SOHC with three valves per cylinder actuated by rocker arms, and the KA24DE is DOHC with four valves per cylinder and shim-over-bucket valve actuation. Other design improvements include the use of a knock sensor, different oil pan (not interchangeable between blocks), different oil pickup, dipstick location and piston oil squirters. In addition to the increased power and torque, the KA24DE has a higher redline than the KA24E.^{[citation needed]}
