Is There a V8 Version of the FJ Cruiser?

The Toyota FJ Cruiser is known for its retro styling, off‑road ability, and reliable 4.0‑liter V6 engine. Since its debut in 2006, enthusiasts have often wondered if a factory V8 version exists. The answer is no, but that has not stopped custom builders from making it happen.

Factory Options

• No Factory V8 – All production FJ Cruisers came with the 1GR‑FE 4.0‑liter V6.
• Power Output – Ranged from 239 hp in early models to 260 hp in later years, with around 278 lb‑ft of torque.
• Transmission Choices – 5‑speed automatic (2WD or 4WD) or 6‑speed manual (4WD only).

Aftermarket V8 Conversions

• While Toyota never offered a V8 FJ Cruiser from the factory, some shops and individual builders have performed engine swaps:

Popular Swap Options

• Toyota 2UZ‑FE 4.7L V8 – Found in the 100 Series Land Cruiser and Lexus LX470. Known for smooth power and Toyota reliability.
• Toyota 3UR‑FE 5.7L V8 – Used in the 200 Series Land Cruiser and Toyota Tundra, delivering up to 381 hp.
• GM LS-Series V8s – Available in many displacements, known for high horsepower potential and broad aftermarket support.

Considerations for a Swap

• Transmission Compatibility – May require adapters or a full transmission swap.
• Cooling Upgrades – Larger radiators and enhanced cooling systems are necessary.
• Fuel Economy – Expect lower mpg compared to the stock V6.
• Emissions Compliance – Local regulations may restrict or require certification for engine swaps.

Why a V8 Swap Appeals to Enthusiasts

• More Power for Towing and Off‑Roading – Significant torque increases make heavy loads and steep climbs easier.
• Improved Highway Performance – Faster acceleration and higher cruising speeds.
• Uniqueness – A V8 FJ Cruiser is rare and stands out in the off‑road community.

There is no factory‑produced V8 Toyota FJ Cruiser, but skilled builders have proven that V8 swaps are not only possible but highly effective. If using a Toyota 2UZ‑FE for OEM feel or a GM LS for maximum power, a well‑executed conversion can transform the FJ into an even more capable and exciting SUV, as long as you are prepared for the cost, complexity, and potential legal considerations.
