The 1986 Nissan D21's horsepower varies by engine and market, but the most common U.S. configuration—a 2.4-liter four-cylinder—produced roughly 120–135 horsepower.
Engine options in the 1986 D21
Engine choices for the D21 in 1986 depended on the market. In the United States, the lineup centered on a 2.4-liter four-cylinder, while some international markets offered smaller gasoline engines or diesel options. The following summarizes the engines most likely found on 1986 D21 pickups.
- 2.0-liter inline-four (gasoline) – typically around 90–105 horsepower, depending on tuning and emission controls.
- 2.4-liter inline-four (KA24E) – commonly around 120–135 horsepower in early to mid-era configurations, with variations due to carburetion vs. fuel injection and emissions equipment.
- Diesel 2.2-liter (CD-series) – generally about 60–75 horsepower, depending on market and turbocharging.
These figures are approximate and can vary by country, model year, emission standards, and whether the truck used carbureted or fuel-injected systems.
Horsepower by engine type (approximate, 1986 D21)
To give a clearer sense of the range, here are commonly cited horsepower figures by engine configuration, noting that actual output can vary by vehicle condition, gearing, and tuning:
- 2.0L I4: about 90–105 hp
- 2.4L KA24E: about 120–135 hp
- Diesel 2.2L: about 60–75 hp
Always verify the exact rating for a specific vehicle by checking the engine code under the hood and the model year’s specifications, as outputs can differ by emissions equipment and market.
Context and nuances
Horsepower on the D21 is not a fixed specification across all units. Early carbureted 2.4L variants tended to show lower numbers, while later fuel-injected versions and regional variants could push outputs higher. Transmission type, rear-axle gearing, and overall vehicle condition also influence the measured horsepower at the crank versus at the wheels.
Summary
For a 1986 Nissan D21, horsepower depends on the engine and market. The most common US-spec configuration used a 2.4-liter four-cylinder with an approximate output of 120–135 hp, while the 2.0-liter and diesel options were lower, around 90–105 hp and 60–75 hp respectively. Check the engine code and the specific market variant to confirm the exact figure for a given truck.
