Pro Xe BMW B58 Gen 2 6 port PX950 Hybrid Turbo Upgrade

Pro Xe PX950 Hybrid Turbo Upgrade – BMW B58 Gen 2 6-Port

The Pro Xe PX950 Hybrid Turbo Upgrade is engineered for BMW B58 Gen 2 owners looking to maximize the performance potential of the factory turbocharger platform without sacrificing the responsiveness and drivability that make the B58 exceptional.

Built around the OEM-style B58 Gen 2 6-port turbocharger configuration, the PX950 incorporates a significantly larger billet compressor wheel, an upgraded high-flow turbine, extensive internal porting, and precision high-speed balancing to deliver exceptional airflow and performance under demanding conditions.

Designed to support up to 950 BHP with the proper supporting modifications, the PX950 targets strong midrange response, improved high-RPM efficiency, and substantial top-end power for high-performance street, drag racing, and roll racing applications.

Features

• Up to 950 BHP estimated airflow capability with appropriate supporting modifications
• 57 mm / 62 mm billet aluminum compressor wheel
• 64 mm / 58 mm high-flow cutback turbine wheel
• Precision-machined compressor and turbine housings to accommodate the upgraded rotating assembly
• Hand-ported and polished compressor and turbine flow passages
• High-temperature ceramic-coated turbine housing
• Precision-assembled and VSR high-speed balanced rotating assembly
• OEM-style bolt-on configuration for compatible B58 Gen 2 6-port applications
• Retains factory-style electronic wastegate, oil, and coolant connections

Benefits

• Significantly increased airflow capacity over the factory turbocharger
• Improved high-RPM exhaust flow with the upgraded turbine geometry
• Reduced exhaust restriction potential under high-load operation
• Strong midrange response with substantially increased top-end performance capability
• Retains the packaging advantages of the factory turbocharger architecture
• Designed for high-boost performance applications
• Supports aggressive power goals without requiring a completely custom turbocharger manifold

Important Fitment Information

The Pro Xe PX950 is designed specifically for B58 Gen 2 / B58TU engines equipped with the factory 6-port turbocharger configuration.

Not compatible with:

• B58 Gen 1 turbocharger applications
• B58 Gen 2 factory 2-port turbocharger configurations
• 2020 Toyota GR Supra 3.0 factory 2-port applications
• B58TU2 applications unless specifically verified

Model year alone does not guarantee fitment. Engine specifications, production dates, and regional configurations may vary.

Customers are encouraged to contact Pro Xe Automotive with their VIN before ordering to verify the correct turbocharger configuration.

Performance Requirements

Achieving the PX950’s maximum estimated power potential requires appropriate supporting modifications, including upgraded fueling, intercooling, custom ECU calibration, and engine/drivetrain preparation appropriate for the intended power level.

Actual horsepower, boost response, and performance will vary depending on fuel quality, engine configuration, tuning, and operating conditions.

950 BHP is a projected capability, not a verified dyno result or guaranteed output.

Professional installation and custom tuning are required.
