Future Motorsports Stage 4 Race 2JZ Cylinder Head – 1300–1600HP

The Future Motorsports Stage 4 Race 2JZ Cylinder Head is our high-performance cylinder head package developed for serious 1300–1600HP Toyota 2JZ-GTE and 2JZ-GE engine builds. Designed for high-power street, drag and competition applications, this package combines our proven port design, precision machining and premium Ferrea valvetrain components.

Our 2JZ cylinder head packages are built from years of experience, development and proven reliability on high-horsepower Toyota Supra and 2JZ applications worldwide.

Stage 4 Race 2JZ Cylinder Head – Proven 1300–1600HP Performance

The Future Motorsports Stage 4 Race Cylinder Head is designed for serious high-horsepower 2JZ applications.

We have 2JZ and Toyota Supra customers worldwide running this cylinder head package at power levels ranging from approximately 1300 to 1600 bhp, with applications ranging from high-powered street cars to dedicated drag cars.

A major focus of our cylinder head development is achieving excellent airflow without unnecessarily increasing port volume. Correct port design, valve seat work and careful attention to the complete airflow path help retain excellent gas velocity and contribute towards the quick turbo spool characteristics our cylinder head packages are known for.

This development comes from years of experience within the performance, aftermarket and racing industries, building high-horsepower engines and competition cars.

Stock-Size 2JZ Valves – Proven to 1600HP

Across our Stage 1 through Stage 4 2JZ Cylinder Head Packages, we utilise factory-size valves up to 1600HP.

This decision is based on practical experience rather than theory.

We have built 2JZ cylinder heads capable of supporting 2000HP using 1.0mm oversized valves. However, our experience has shown that for builds targeting approximately 1300–1600HP, correctly prepared stock-size valves can provide the required airflow without unnecessarily moving to oversized valves.

Bigger isn't automatically better. The complete cylinder head combination – including port design, valve seat profile, chamber work, camshaft specification and valvetrain setup – is what ultimately determines performance.
