Ready to unlock serious power from your N54 without the headaches of a full custom turbo swap? These brand-new TD04 hybrid twin turbochargers are purpose-built for the BMW 135i, 335i, 535i, and Z4 platforms. Each unit receives a high-flow forged billet compressor wheel (choose between 17T or 19T) and a matching upgraded turbine wheel designed to move significantly more air while keeping lag under control.
The 17T setup delivers an excellent mix of quick response and strong mid-range power, easily supporting builds in the 600 hp range with the right supporting mods. Step up to the 19T for maximum airflow and the ability to push into the 650 and beyond. Both sizes are available with either 6+6 or 11-blade billet compressor wheels featuring extended-tip technology for improved efficiency and higher flow capacity.
Beyond the wheels, these turbos include reinforced wastegate actuators, stronger internal components, and upgraded thrust assemblies. Every set is precision balanced — component, dynamic, and VSR — so they remain smooth and reliable even under elevated boost. They bolt directly in place of the factory turbos using the original oil and coolant lines, making installation straightforward. Optional high-flow inlet pipes and downpipes are available if you want a complete airflow package.
A proper tune is required to take full advantage of the extra capacity. Whether you’re building a strong street car or a track-focused N54, these hybrids give you a practical, bolt-on path to substantially higher performance while retaining daily-driver reliability.
