Facts You Should Know About Nissan KA24DE Engine

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.

Nissan KA engine first introduced in 1988 as a replacement for the outdated Z24 engine.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 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

KA24DE Engine Specifications

The KA24DE 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 KA24DE 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

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 KA24DE engine if you using low-quality engine oil. When timing chain begins to work too noisy, the process of motor destruction has already started.

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.

Nissan KA24DE engine production stopped in 2004 due to the release of more advanced 2.5L Nissan QR25DE.
