KA24DE Information

Many owners will swap their ka24de with an sr20det especially when it comes to a 240sx application, is it worth it? 

If you must have more power under the hood, at least try to transform your ka24de into a KA-T (turbo), many have done so successfully & safely, as the stock ka24de block can handle up to 450 rwHp & in comparison to sr20det a KA-T can rack up +50 Hp more than a stock unmodified SR20.

Whatever your decision is, here are some helpful  specs & information on your ka24de.

The 2.4 L (2389 cc) was used in many Nissan cars and trucks. Most of KA24DE 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.

KA24E+T & KA24DE+


Aftermarket turbocharger kits are available for the KA24DE as well as many other Nissan engines. After the engine is turbocharged, it is generally referred to as a KA24DET. The KA24DET was never produced by Nissan. The "T" at the end of the engine code indicates that the engine is turbocharged. The turbocharger is added to increase power in Nissan's 2.4 L DOHC inline 4 engine. Some enthusiasts turbo charge their KA24E (SOHC) and they call it the KA24ET. This was also never produced by Nissan in a turbocharged version.

If you already swapped your engine with an sr20det engine, take a look what JDM Car Parts has to offer.

2010-07-29
It looks like a very beefy transmission, and if I can use it in a auto to stick swap, I sure would like to know if it can be done. Also, I am told that spun bearings are common for 240sx's.
