6. Detailed Product Description

The 20B with a Borg Warner 300SX-E turbo, ZF 8HP trans, and Link FuryX ECU/Razor PDM in control represents the evolution of modern rotary performance. Instead of relying on outdated factory electronics and aging hardware, this package integrates today’s most advanced technology into one complete, ready-to-install powertrain.

At the heart of this build is Mazda’s legendary 20B three-rotor engine. Known worldwide for its smooth operation, unmistakable rotary sound, and incredible power potential, the 20B remains one of the most desirable rotary engines ever produced.

To maximize airflow and efficiency, this engine is equipped with a Borg Warner 300SX-E turbocharger, a favorite among professional builders for its quick spool characteristics, excellent compressor efficiency, and ability to support substantial horsepower without sacrificing responsiveness.

The engine is paired with a ZF 8HP transmission, widely regarded as one of the finest modern automatic gearboxes available. Fast gear changes, exceptional durability, and outstanding street manners make this transmission the preferred choice for many high-performance builds around the world.

Engine management is handled by the highly respected Link FuryX ECU, delivering advanced tuning capabilities, extensive data logging, boost control, safety strategies, and flexible calibration options. Complementing the ECU is a Razor PDM, replacing conventional fuse and relay systems with a modern programmable power management solution that improves reliability while simplifying wiring.

Internally, the engine benefits from numerous precision machining processes including:

• CNC extended porting
• CNC doweling
• In-house CNC performance modifications
• Blueprinted assembly
• Premium sealing components

High-quality I-Rotary apex seals have been installed to improve durability while maintaining excellent sealing under high boost conditions.

The Bosch Drive-By-Wire system provides incredibly smooth throttle response while allowing advanced tuning features such as traction control, launch control, boost-by-gear, idle control, and multiple engine maps.

Every aspect of this engine has been designed around creating an exceptionally reliable, responsive, and enjoyable street rotary without compromising performance.
