PA TD04 20T Billet Compressor Wheel Performance Hybrid Twin Turbochargers for BMW 135i 335i 535i and Z4 N54 Engine

Introducing our PA TD04 20T Billet Compressor Wheel Performance Hybrid Twin Turbochargers for BMW 135i, 335i, 535i & Z4 N54 Engines

Push your N54 further than ever with the largest hybrid option in our TD04 lineup.

These are brand-new TD04 hybrid twin turbos built exclusively for the BMW N54. Stock compressor wheels are swapped for oversized high-flow billet units, matched to larger turbine wheels, delivering substantially more airflow and the ability to support serious power numbers while staying a true bolt-on solution.

Available configuration:

• 20T – Maximum-flow option engineered for top-end power (supports 700 hp range with proper supporting modifications)
• Billet compressor wheel construction
• Optional high-flow inlet pipes and downpipes available for a complete package

Key specifications & upgrades:

• Compressor: 47 mm inducer / 60 mm exducer billet wheel, 52 mm inlet
• Turbine: 46 mm exducer / 52 mm inducer with 0.41 A/R housing
• Ball-bearing cartridge for improved durability and response under elevated boost
• Reinforced wastegate actuators and upgraded internal components
• Precision balanced (component + dynamic + VSR) for reliable high-boost operation

These turbos bolt directly in place of the factory N54 units using the original mounting points, oil lines, and coolant lines. Installation remains straightforward. A custom tune is required to unlock the full potential.

Select the 20T when your goal is maximum airflow and power capability in a stock-location package. Designed for high-performance street and track N54 builds that still need daily reliability.
