The 1986 Nissan Pickup, commonly known in North America as the Datsun 720, offered two inline-four engine options: a 2.0-liter L-series (L20B) and a 2.4-liter Z-series (Z24).
In the United States and other markets, both engines were used across different trims and production runs. Availability depended on the specific model year, emissions rules, and whether the engine was carbureted or fuel-injected. Engine identification generally comes down to the stamping on the engine block and the vehicle’s option labels.
Engine options for the 1986 Nissan Pickup
The two primary gasoline powerplants used in the 1986 Nissan Pickup (Datsun 720) are described below, with notes on fuel delivery and typical output ranges.
- 2.0-liter inline-four (L20B): commonly found in base and some mid-level models; configurations could be carbureted or fuel-injected depending on the production date and market. Output typically falls roughly in the 95–110 hp range, varying with emissions gear and fuel system.
- 2.4-liter inline-four (Z24): offered in higher trims and later production batches; some versions were carbureted while others used electronic fuel injection. Output generally sits around the 110–135 hp range, with exact figures depending on configuration and emissions equipage.
Engine availability and performance for the 1986 Nissan Pickup varied by market, with the L20B and Z24 representing the two core gasoline options during that period. Always verify the exact engine from your vehicle’s codes and documentation.
How to tell which motor you have
To confirm the exact engine in your truck, use these steps and look for identifying codes and features.
- Check the engine code stamped on the engine block or valve cover (L20B for the 2.0 L, Z24 for the 2.4 L).
- Inspect the vehicle’s emission sticker, VIN decode, or door jamb tag for the listed engine option.
- Compare distinctive fuel-delivery elements: carburetors indicate older configurations, while electronic fuel injection points to EFI-equipped variants.
Engine codes to look for
Common codes to identify the motors are L20B for the 2.0-liter and Z24 for the 2.4-liter, but the exact stamping and labeling can vary by market and build date. If in doubt, cross-check with the VIN and factory documentation.
Knowing the precise motor helps with parts compatibility and maintenance, especially if you’re planning repairs, restorations, or upgrades on a 1986 Nissan Pickup.
Summary
The 1986 Nissan Pickup (Datsun 720) offered two main gasoline engines: a 2.0-liter inline-four (L20B) and a 2.4-liter inline-four (Z24). The exact setup—carbureted or fuel-injected—varied by market and production period. To confirm which engine your truck has, check the engine code on the block, review the vehicle’s option labels or VIN decoding, and note the fuel delivery system.
