Short introduction
If you’re looking for a durable, no-frills compact truck from the early '80s, the 1984 Nissan pickup (model 720) is worth considering—especially if you value mechanical simplicity and long-term reliability. How to choose a 1984 Nissan pickup comes down to one key factor: the engine. Most models came with the 2.4L Z24 inline-four, an 8-valve SOHC engine known for lasting well over 200,000 miles when maintained. If you’re a typical user, you don’t need to overthink this. The Z24 was the standard engine, carbureted, iron-block with aluminum head, and often equipped with dual spark plugs per cylinder for improved combustion. Avoid models with unclear service history or rust-heavy frames—these are more critical than engine code alone. Recently, interest in these trucks has grown due to their affordability as restoration projects and strong parts availability.
About the 1984 Nissan Pickup
The 1984 Nissan pickup, officially known as the Nissan 720 series, replaced the earlier Datsun 720 and marked a transition toward the 'Hardbody' design language that would define Nissan trucks into the 1990s. Available in rear-wheel drive (RWD) and four-wheel drive (4x4) configurations, it was marketed as a compact workhorse suitable for light hauling, farming, and daily driving in rugged conditions. Trim levels included Deluxe and Standard, with options for long bed or short bed, manual or automatic transmission, and solid-axle suspension.
This truck was part of Nissan’s push to establish reliability in the North American market. Unlike flashier competitors, it focused on durability, fuel efficiency, and ease of repair. The cab design offered basic comfort, with minimal sound insulation and analog gauges. Over the past year, vintage truck enthusiasts have increasingly turned to the 720 as a low-cost entry point into classic ownership—especially those seeking a platform for mild off-roading or urban utility use.
Why the 1984 Nissan Pickup Is Gaining Popularity
Lately, the 1984 Nissan 720 has seen renewed attention not because it’s powerful or luxurious—but because it’s predictable. In an era of complex electronics and sealed engines, a carbureted, mechanically simple truck offers something rare: transparency. You can diagnose most issues with a multimeter and a wrench.
This piece isn’t for keyword collectors. It’s for people who will actually use the product.
The rise in popularity also ties to practical factors: parts for the Z24 engine remain widely available, and the chassis is compatible with later Nissan components. Its compact size makes it easier to park and maneuver than modern pickups, while still offering ~1,500 lbs payload capacity. Enthusiasts appreciate its lightweight frame for off-grid camping builds or minimalist desert rigs. Restoration forums and YouTube channels have amplified visibility, showing complete rebuilds under $3,000—making it accessible even on a tight budget.
Types and Variants
The 1984 Nissan 720 came in several configurations, though engine options were limited in most markets.
1. 720 RWD (Rear-Wheel Drive)
- Pros: Better fuel economy (~22 mpg highway), lighter weight, simpler drivetrain, lower purchase price
- Cons: Less traction in snow/mud, not ideal for heavy towing or steep inclines
2. 720 4x4 (Four-Wheel Drive)
- Pros: Improved off-road capability, locking hubs, stronger transfer case, better resale among collectors
- Cons: Heavier, slightly lower fuel efficiency (~18 mpg), more maintenance points (driveshafts, U-joints)
3. Engine Variants
While most 1984 models used the Z24 2.4L carbureted inline-four, some export markets may have received diesel or smaller gasoline variants. However, in North America, the Z24 was essentially standard.
- Z24 (Carbureted): Reliable, easy to tune, widely supported
- Z24i (Fuel Injected): Introduced in later years—rare in 1984; avoid assuming your model has it unless verified
If you’re a typical user, you don’t need to overthink this. Unless you're importing from Japan or Europe, expect the carbureted Z24.

How to Choose a 1984 Nissan Pickup
Follow this step-by-step guide to make a smart purchase.
Step-by-Step Checklist
- Verify engine type (Z24 2.4L I4)
- Inspect frame for rust, especially near suspension mounts
- Check for smooth transmission engagement
- Test 4x4 system (if equipped) on incline or loose surface
- Confirm dual spark plug operation
- Review service history or maintenance records
- Start cold to detect hard-starting or flooding
- Examine bed for rot or patch repairs
Decision Flow
- Are you using it for work or restoration? → Choose 4x4 if off-road or rural.
- Is budget under $3,000? → Prioritize RWD with clean title.
- Do you want low maintenance? → Ensure carburetor is tuned and cooling system flushed.
- Is long-term ownership likely? → Invest in a rust-free example even if pricier.
Recommendations by Scenario
- Daily Driver (Urban): RWD, manual transmission, standard cab
- Weekend Off-Roader: 4x4, long bed, lift kit already installed
- Restoration Project: All-original, low-mileage, matching numbers
- Budget Hauler: Any running model with solid frame
Red Flags / What to Avoid
- Severe frame rust – structural integrity compromised
- No service history – hidden engine wear likely
- Replaced engine without documentation – could be mismatched or damaged
- Flood damage signs – mud in cabin, musty smell, corroded connectors
- Non-functional 4x4 – expensive to fix transfer case or differentials
If you’re a typical user, you don’t need to overthink this. A running 720 with a solid frame beats a 'project' with unknowns every time.
