TTE1140 5554 S58 BMW M3/M4 X3M /X4M UPGRADE TURBOCHARGERS & INLETS

The TTE1140 represents the pinnacle of S58 hybrid turbocharging, evolved directly from the race-proven TTE940 Stage platform. Engineered for maximum performance, these turbos deliver exceptional flow, efficiency, and durability for the ultimate plug-and-play upgrade.

Advanced Turbo Design

Each TTE1140 turbo begins with the removal of the original compressor wheels, replaced with 55mm billet wheels that offer significantly increased efficiency. The compressor covers are precisely machined to achieve optimal clearances, fully matching the new compressor profile. On the turbine side, TTE 9-blade low-mass 54mm turbines are installed in the housings to maximize exhaust flow, reduce gas temperatures at high boost, and support sustained performance. A TTE upgraded bearing pack ensures longevity under extreme conditions.

High-Performance Inlets

TTE provides dedicated upgrade turbo inlets compatible with the OEM air intake system or optional EVENTURI intakes, delivering unrestricted airflow and seamless installation. This combination unlocks the full power potential of the TTE1140, providing a complete high-performance hybrid solution.

Precision Equilibrium

Optimal balance is critical for both performance and durability. TTE turbochargers undergo a meticulous multi-stage balancing process. Components are first balanced at slow speeds up to 2,800 RPM using single-part machines. After assembly, the CHRA is dynamically balanced at speeds up to 250,000 RPM (depending on application) using TTE’s in-house VSR machine, ensuring stability, longevity, and superior acoustics. Each turbocharger is supplied with a serial-numbered balance test certificate, exceeding OEM standards for reliability and precision.

The TTE1140 upgrade delivers a perfect fusion of engineering excellence, peak performance, and plug-and-play convenience, setting a new benchmark for S58 turbocharging.
