TTE500 – Upgrade Turbos – BMW 135i E8x / 335i E9x N54

Description

The TTE500 is the ideal entry-level hybrid turbo upgrade for BMW models with the N54 engine. This kit combines high performance, rapid response, and proven reliability in a fully plug-and-play configuration. With a potential output of over 500 hp on 98 RON fuel, it's the perfect upgrade for those who want more power without compromising on ease of installation or durability.

Based on the original N54 turbochargers, the TTE500 units are completely redesigned internally. The standard compressor wheels are replaced by TTE's advanced billet compressor wheels with next-generation geometry for improved efficiency and increased airflow. On the exhaust side, the TTE High-Flow turbine ensures lower exhaust gas temperatures, less backpressure, and faster spooling.

Each unit is equipped with the reinforced TTE bearing package for optimal durability under high boost pressures. Optional TTE upgraded wastegates—including reinforced flappers, arms, and bushings—are available for added stability under extreme loads. Each turbocharger is individually balanced on the in-house VSR machine up to 250,000 rpm and comes with an official balance report with a serial number.
