TTE460 BMW N55 Hybrid Turbocharger Upgrade | 135i & 335i E-Chassis 2010-2013 | TheTurboEngineers

TTE460 uprated turbo for BMW N55 3.0 petrol six, E82 135i and E90 E92 335i

Looking for a serious step up in boost without compromising drivability or reliability? The TTE460 is a stock-location, bolt-on performance charger for BMW’s N55-powered E-chassis 135i and 335i that delivers rapid spool, hard-hitting midrange and strong top-end on pump fuel. Built from a brand new genuine unit and re-engineered in Germany by TheTurboEngineers, this is the go-to drop-in solution for drivers who want big gains with OEM-like manners.

Key reasons enthusiasts choose TTE460

• High-efficiency billet compressor wheel with a wide operating window for strong flow and cooler charge air
• CNC-machined compressor cover with optimised clearances for improved efficiency and response
• Ported inlet pathway for reduced restriction and smoother airflow into the wheel
• Curved clipped turbine to lower exhaust back pressure and temperatures, enabling safer higher boost targets
• Lower rotating mass for faster spool and sharper throttle response
• Retains genuine actuator and bypass valve for factory-like behaviour and refinement
• Direct replacement in the factory position, no fabrication required on E-chassis N55 135i and 335i
• Precision balanced and supplied with an individual balance report
• Engineered and assembled in Germany by TheTurboEngineers
• Proven capability of 470+ PS on 98 RON with supporting hardware and calibration

Real-world gains you can feel

Dyno data on the N55 platform shows what this uprated unit can do: 472 PS and 637 Nm demonstrated, with strong, repeatable performance on road and track. Expect rapid spool for street use, a muscular midrange and sustained pull to the redline.

Built for longevity and quiet confidence

Each cartridge is balanced in stages, from component balancing up to 2,800 rpm, through to full CHRA dynamic balancing up to 250,000 rpm. The result is smooth operation, durability and refined acoustics, backed by a serialised balance sheet with every unit.
