When used in the passenger cars both versions of the KA24 used a crankshaft girdle, as opposed to individual main bearing caps.

Most KA24DEs bound for the US were built in the city of Aguascalientes, Mexico, 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 Yokohama, Kanagawa, Japan.

The head and block are non-interchangeable between all other models and are uniquely cast for front wheel drive operation.

They also used a single row chain for the upper timing assembly without valve cover mounted guide.

The crank rides on individually capped bearings with a slightly smaller diameter than the Japanese block, with shorter, slightly lower compression pistons in cylinders that have thicker walls than the Japanese DE.
