Detailed Product Description

The Rebuilt 0-Mile Turbo II Engine has been assembled to provide enthusiasts with a dependable, performance-ready rotary engine that eliminates the uncertainty associated with high-mileage or untouched used engines.

Every critical component has been carefully selected to maximize reliability while maintaining excellent power potential. From the premium apex seals to the upgraded oiling system, every detail contributes to creating a rotary engine capable of handling demanding street and performance applications.

One of the highlights of this build is the use of Rotary Aviation 2mm Cryo Apex Seals. These high-quality seals are widely respected throughout the rotary community for their strength, durability, and resistance to wear under high-performance conditions. Combined with cryogenically treated side seals, the engine is better equipped to withstand increased cylinder pressures and long-term operation.

The engine has also been fitted with a Big Street Port, professionally machined to improve airflow while maintaining excellent throttle response and street manners. This port configuration strikes an ideal balance between daily drivability and increased horsepower potential.

To further improve long-term reliability, the engine features external oil passages, enhancing lubrication to critical internal components. This modification is particularly beneficial for performance-oriented rotary applications where consistent oil delivery plays an important role in engine longevity.

Rather than using aftermarket studs, this engine has been precision dowelled, ensuring accurate alignment and excellent structural integrity throughout the engine assembly.

An OEM rebuild kit supplied by RA has been used wherever appropriate, helping maintain factory-quality sealing and fitment while complementing the upgraded performance components.

Because the engine has zero miles since rebuild, buyers receive a fresh engine ready for break-in and tuning according to their specific application.
