BMW S58 Pure Turbos Stage 2+ Turbo Upgrade

Upgrade your BMW S58 with the Pure Turbos Stage 2+ Turbo Upgrade — a high-performance OEM housing turbo upgrade designed for serious BMW M2, M3, M4, X3 M and X4 M builds.

Built for the 3.0L S58 twin-turbo engine, the Pure Stage 2+ upgrade is designed to support major power gains while retaining an OEM-style turbocharger fitment. This makes it a strong option for customers chasing serious street, track or drag performance without moving to a completely custom turbo setup.

Designed for the BMW S58

The BMW S58 is one of BMW M’s strongest modern engines, with excellent tuning potential and a proven ability to make serious power with the right supporting modifications.

The Pure Stage 2+ turbo upgrade is designed to increase airflow, improve top-end performance and support high-output S58 builds when paired with the correct fuel, supporting hardware and custom ECU calibration.

900+ WHP Capable

Pure Turbos rates the Stage 2+ S58 upgrade as capable of supporting 900+ WHP, with final results depending on fuel type, supporting modifications, tuning strategy and vehicle condition.

As with any upgraded turbo setup, final output will vary between vehicles. Correct fuelling, cooling, exhaust flow, intake flow, engine health and ECU calibration are all critical to achieving safe and reliable results.
