Nissan KA engine
Encyclopedia
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 head
s were made of aluminum.
Despite their large capacity, this motor was not equipped with balance shaft

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 features forged steel connecting rods, an internally balanced forged steel crankshaft, and a cast aluminum intake manifold.
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, 1994-97 Altima (re-badged Bluebird SSS), and the U13 Bluebird released in Australia with FWD configuration which were manufactured in Fukuoka Prefecture
, Japan
. The Mexican block is the same as the KA24E but has a DOHC head on it and doesn't incorporate the design improvements of the block from Japan. The KA24DE is very similar to the KA24E. 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. Design improvements of the block from Japan include the use of a knock sensor, girdled main bearings, different oil pan (not interchangeable between Japanese and Mexican blocks), different oil pickup (front pickup on Japanese block and side on Mexican block), dipstick location (toward the rear of block on Mexican and mid block on Japanese) and piston oil squirters. In addition to the increased power and torque, the KA24DE has a higher redline than the KA24E.
