• New FD3S 13B-REW rotor housings
• Power seals installed
• Rotors
• Full seal set

Built for Serious Rotary Enthusiasts

The 13B-REW remains one of Mazda’s most iconic rotary powerplants. Found in the legendary FD3S RX-7, the twin-rotor turbocharged engine has earned a reputation for smooth power delivery, lightweight construction, and immense tuning potential.

Starting with fresh components is critical when building a reliable rotary engine. Used housings, worn irons, damaged rotors, or questionable seals can quickly compromise performance and longevity.

This engine core removes those concerns by providing a fresh starting point that allows builders to assemble an engine with confidence.

Zero Run Time Advantage

One of the biggest advantages of this package is its zero-run-time condition.

Unlike used engine cores that may have unknown mileage, overheating history, detonation damage, or internal wear, these components have never been operated.

Benefits include:

• Maximum sealing efficiency
• Improved compression potential
• Greater long-term durability
• Reduced risk of premature rebuilds
• Better reliability under boost

Ideal for OEM Restorations

Finding original FD3S engine components in excellent condition has become increasingly difficult.

Many RX-7s have undergone decades of modifications, racing, or multiple rebuild cycles. For restoration enthusiasts looking to return their vehicle to factory specifications, this package provides an exceptional starting point.

The original geometry and design characteristics of the 13B-REW platform are preserved, allowing builders to maintain authenticity while benefiting from fresh components.

Perfect for Performance Builds

The 13B-REW is renowned for its tuning flexibility.

This engine core can serve as the foundation for:

• Street performance builds
• Weekend track cars
• Time attack vehicles
• Drift cars
• Drag racing projects
• High-boost turbo setups
• Professional rotary race engines

Builders can customize porting, seals, turbo systems, fuel systems, and engine management solutions according to their performance goals.

Precision Rotary Engineering

Rotary engines operate differently from traditional piston engines.

Component condition is crucial for:

• Compression retention
• Oil control
• Rotor stability
• Thermal management
• High-RPM reliability

Beginning with fresh housings, seals, and major internal components provides builders with the best opportunity to achieve excellent performance and durability.
