BMW & Toyota B58 Stage 3 Hybrid Turbo | Supra MK5 A90 Z4 G29 | 600 HP

Serious Performance Upgrade

The B58 engine is famous for its strength, but the stock BorgWarner turbocharger is the primary bottleneck for those chasing 600 HP. Our Stage 3 Hybrid modification redefines the capabilities of the factory housing. By installing significantly larger, custom-engineered internals and precision-machining the housings, we unlock the airflow needed for high-boost applications. This is the ultimate choice for Supra and Z4 owners who want a true “bolt-on” monster that maintains the factory engine bay look.

Why This Turbo Wins

• Target power of 580-600 HP
• Lightning-fast spool thanks to lightweight CNC Billet technology
• Custom 9-blade high-flow turbine for reduced backpressure
• Reinforced performance bearing system for stable high boost
• 100% Plug & Play—no custom lines or adapters needed
• Utilizes original high-quality BorgWarner actuator
• Precision balanced on VSR machines at real-world operating speeds

Internal Upgrades

• Custom CNC Billet Compressor Wheel: Larger aerodynamic surface area designed to move significantly more air mass.
• 9-Blade High-Flow Turbine Wheel: A custom profile that allows exhaust gases to exit faster, lowering EGTs and increasing top-end pull.
• Upgraded Bearing System: Features reinforced journal bearings designed to handle the increased axial and radial loads of high-power tuning.
• Precision Machined Housings: Exhaust and compressor housings + sealing plates are CNC profiled for maximum volumetric efficiency.
• VSR High-Speed Balancing: Each core is balanced at speeds nearing the turbo’s physical limit to ensure long-term reliability under extreme stress.

Performance Characteristics

Despite the significant increase in size, the Stage 3 B58 Hybrid retains the engine’s famous “instant-on” torque feel. The lightweight CNC wheel ensures the spool is sharp and responsive for street driving, while the 9-blade turbine allows the power to climb relentlessly until the redline. This setup eliminates the top-end “choking” common with the stock turbo, making it a weapon on the highway and track.
