Various Nissan cars and trucks is utilized with Nissan KA24DE Engine series. It is a 2.4L inline four-cylinder engine that uses an iron cylinder block with an aluminum cylinder head. The KA24DE is the engine that almost all Nissan 240SX series used in America.
If you have been around the drifting field especially in the US, well then you’ve probably familiar with the Nissan KA24DE engine.
KA24DE History
Nissan KA engine first introduced in 1988 as a replacement for the outdated Z24 engine. There were 3 engines in the Nissan KA series.
- The KA20DE
- The KA24E
- The KA24DE (had the most power)
The KA24DE was introduced as an upgrade to the KA24E engine, boasting a dual overhead camshaft (DOHC) and 4 valves per cylinder, a departure from its predecessor’s single overhead cam design. This modification paved the way for larger inlet valves, improved knock sensors, and a revised oil pickup system. Consequently, the engine’s redline surged to 6900 rpm from 6500 rpm, offering better performance.
One of the remarkable traits of the KA24DE engine is its tuning potential. Car enthusiasts can explore upgrades, including turbocharging, to squeeze out more horsepower. This makes it a budget-friendly option for those exploring the drifting scene.
Comparatively, the KA24DE holds its ground against other engines like the SR20DET, thanks to its sturdy build and tuning flexibility. The engine’s strengths lie in its robustness and potential for modifications. At the same time, its weaknesses are seen in its somewhat heavier build, primarily due to its initial design for trucks and SUVs.
KA24DE Engine Specifications
The breakdown of the KA24DE engine code is as follows:
KA – Engine Family
24 – 2.4 Liter Displacement
D – DOHC (dual overhead camshafts)
E – Multi Point Fuel Injection
The KA24 engine is crafted with shaped iron block and an aluminum head. The valvetrain for this engine, is dual overhead camshaft. This 4 cylinder engine has a total amount of 16 valves, with 2 intake and 2 exhaust valves every cylinder.
The KA24DE engine is very similar to the KA24E, but you will find a few fundamental differences that separate these kinds of engines. The only major change is the cylinder head design. As the KA24E has a Single-Overhead Cam (SOHC) with 3 valves per cylinder, the KA24DE has Dual-Overhead Cams (DOHC) with 4 valves per cylinder.
Other development changes include the use of a knock sensor, oil injection at the base of each piston, and top-firing spark plugs.

KA24DE-T’s
In addition to the increased power and torque, the KA24DE engine has a slightly wider power than the KA24E. These engines have already been proven to be quite tough. In turbocharged form with stock long block 500+ whp has been achieved but short lived and 1000+ whp fully built.
There are a variety of stock block 300+ whp daily driven KA24DE-T’s. This engine has pushed into the 7 seconds in the 1/4 mile in some Nissan 240SX’s. With their large stroke these engines are well known for getting low revving torque monsters considering the torque numbers have already been known to stick to or even higher than hp outcome.
Cars That Use the KA24DE Engine
Nissan set the KA24E and KA24DE in their various car production series. Some engines were destined for light duty pickup or trucks and SUV series such as the Nissan Hardbody or Nissan Xterra, but the nissan KA24 engine is best known for its appearance in the 240SX. It makes sense just to adapt the engine for multiple platforms rather than creating an all-new engine.

KA24DE Engine Reliability and Common Problems
Since its introduction, the Nissan KA24DE engine, a 2.4-liter inline-four engine, has been a reliable power plant for various Nissan vehicles. Its cast-iron block and durable design have earned a reputation for robustness among automotive enthusiasts. However, like any engine, the KA24DE has its share of common issues, often minor and manageable with regular maintenance.
Reliability Attributes
- Durable Cast-Iron Block: The cast-iron block of the KA24DE engine is known for its durability and toughness, providing a solid foundation for stock and modified applications.
- Maintenance-Friendly Design: Its design facilitates ease of maintenance, contributing to its longevity. The engine’s reliability is further enhanced when maintained properly, including timely oil changes and adherence to service schedules.
- Timing Chain Over Belt: Unlike engines with timing belts, the KA24DE employs a timing chain, which has a longer lifespan and requires less frequent replacement, provided it’s maintained properly.
Common Concerns
- Valve Cover Gasket Failure: A typical issue with the KA24DE engine is the failure of the valve cover gasket, which can lead to oil leaks. Replacing the gasket is a straightforward fix for this problem.
- Faulty Distributor: Distributor problems are common, leading to starting issues or erratic engine behavior. A replacement distributor or repair kit can resolve this issue.
- Timing Chain Rattle: Particularly in high mileage engines or 1st generation models, the timing chain may exhibit a rattling noise, often described as marbles in a jar during idle. This is more of an annoyance than a serious problem. Still, a timing chain guide or tensioner replacement can help alleviate the noise.
The Nissan KA24DE engine has a couple of known problems that are common. The manufacturer is known for failing on earlier versions of the KA24 engine. Another typical KA24DE problems is a rattling timing chain, which occurs when the timing chain gets loose from age and begins to rub against the timing chain cover.
It’s advised to maintain KA24DE engine periodically and buy only high class engine oil. Oil pressure on front-wheel drive cars can decrease if to press oil pan slightly. In this instance, it’s necessary to remove oil pan to examine the condition of oil receiver pick up pipe. You can easily destroy the engine if you using low-quality engine oil. When timing chain begins to work too noisy, the process of motor destruction has already started.
Nissan KA24DE engine production stopped in 2004 due to the release of more advanced 2.5L Nissan QR25DE.
Widley known for having great endurance and reliability, Nissan KA24DE engine doesn’t require any special care. Yet KA24DE engines have high fuel consumption (do not be surprised with it). But in total, KA24DE engine is a secure and durable motor.
