Which Is The Best Toyota Engine For A Land Cruiser?

A question that’s hotly contested among enthusiasts is which used Toyota engine is the best available option for their classic Land Cruiser.

The engine is just one part of the powertrain equation. From the transmission to the fuel delivery system to the tires, what you combine can affect your vehicle's overall capabilities and performance. All relevant factors must be considered when buying a used engine online. However, here we always have the high-performance and reliable Toyota Land Cruiser classic engine.

The Old Reliable: Toyota’s Original F Engine

The original F engine was released in November 1955. It had 23% more horsepower than the previous Land Cruiser engine and quickly became known for its ability to produce high torque at low rpm.

One thing you'll notice about this engine is its large cast iron block. This is just one of the reasons these engines were considered nearly indestructible. Some even claimed that Toyota's F engine would go 500,000 to 600,000 miles before it finally shut down.

F engine Specifications

• 3.9-liter, inline 6, with carburetor
• Production years: 1955-1974
• Horsepower: up to 125 hp at 3,600 RPM
• Torque: nearly 209 lb-ft of torque at 1,800 RPM
• Fuel: Gasoline
• Transmission: three-speed or four-speed manual
• Great for off-roading, weekend drives, and adventures.
• F engine models for Land Cruiser: FJ25, FJ40, FJ43, FJ45LV

The All-Out Classic Performer: Toyota’s 2F Engine

Over its nearly 20 years of production, the original F engine has undergone many improvements. It seemed to get better over time. But it morphed into something else with the bigger and stronger 2F.  

The 2F-type engine was installed in the newly developed FJ56V and was later installed in other models. It was the engine that gave Toyota's larger 4×4s a much-needed horsepower boost.

A closer look at this engine reveals that the steel fan of the original F engine has been replaced with a plastic fan, but the cast iron block is still there. The 2F engine is bigger than the F but more efficient and its parts are more readily available and easier to replace.

2F Engine Specifications

• Production years: 1975-1988
• Horsepower: about 135 hp at 3,600 RPM

• Fuel: Gasoline
• Transmission: 4-speed manual or 5-speed manual
• Great for off-roading, driving around town, and highway driving.

The Modern Monster: Toyota’s 1FZ Engine

The Toyota 1FZ makes its U.S. debut with the Land Cruiser 80 Series. Like its predecessors, the F-Series engine features a cast-iron engine block, continuing Toyota's tradition of extreme durability and reliability. Toyota's largest in-line 6-cylinder engine.

1FZ Engine Specifications
