Stock horsepower for Nissan’s 2.4-liter inline-four engines typically sits around 150 horsepower for the KA24DE variant, with older KA24E units generally lower at about 125–140 hp. Exact output depends on year, market, and emissions tuning.
Understanding the 2.4L Nissan engine family
The Nissan 2.4-liter lineup primarily includes two main engine codes: KA24DE (dual‑overhead cam) and KA24E (single‑overhead cam). Both displace roughly 2.4 liters and were used in a range of pickups, sedans, and sport-oriented models throughout the 1990s and early 2000s. Output varies by year and market, so precise figures depend on the specific vehicle.
Horsepower by variant
The most common 2.4L engines are KA24DE (DOHC) and KA24E (SOHC). The figures below reflect stock factory ratings and can vary by year and market.
KA24DE (DOHC 2.4L)
Stock power figures for KA24DE in typical U.S.-spec applications are around 150 horsepower, with torque near 160 lb-ft.
- Horsepower: about 150 hp (112 kW); Torque: about 160 lb-ft (217 Nm)
Note: Output can vary by model year and emission-spec calibration.
KA24E (SOHC 2.4L)
Stock power figures for KA24E are generally lower, around 125–140 horsepower, with torque around 145–150 lb-ft.
- Horsepower: about 125–140 hp (93–104 kW); Torque: about 145–150 lb-ft (197–203 Nm)
KA24E performance also varies by market and year, reflecting different emissions controls and tuning.
Model examples and era notes
These engines appeared in several Nissan models during the 1990s and early 2000s. The KA24DE powered sportier or higher-spec variants such as the 240SX (S13/S14) and some Frontier models, while KA24E was used in earlier Hardbody trucks and other applications. Output figures above align with factory ratings for typical configurations from those periods.
- Nissan 240SX (S13/S14) – commonly KA24DE with roughly 150–155 hp in U.S. markets
- Nissan Hardbody/D22 pickups and related models – KA24E/KA24DE variants with roughly 125–150 hp depending on year and market
- Early Nissan Frontier (late 1990s–early 2000s) – KA24DE in stock form at about 150 hp
For a precise number on a specific vehicle, check the engine code on the block and refer to the original factory specifications for that VIN-year combination.
Summary
In short, the Nissan 2.4-liter engine family centers around roughly 150 hp for the KA24DE variant and about 125–140 hp for the KA24E variant, with variations by year, market, and emissions tuning. When evaluating a specific car, confirm the engine code and consult the official specs for that exact model year.

How long do KA24DE engines last?
250k-300k miles
They'll go for a LONG time with proper care. My KA24de died when it hit the 180k mark. The previous owner didn't really take care of it, and neglected oil changes. A well maintained KA can last up to 250k-300k miles from what I have seen, which means that one is most likely on its last legs.
