Turbosystems BMW B58C (for G-series 2 ports) hybrid turbocharger

This Turbosystems bolt-on hybrid turbo is intended for BMW G-series models with the B58C engine, as listed by the manufacturer. Its upgraded compressor and turbine sides provide more capacity than the standard turbo and stronger components for tuned engines.

Futurez is an importer and partner of Turbosystems. It has long been our most popular upgrade-turbo brand, and for good reason: in our experience these turbos have proved exceptionally durable even in demanding use.

This is a sound choice when the standard turbo is reaching its limit but clean installation, responsive road manners and a broad usable powerband are still important.

Several versions are available, with manufacturer-stated power potential ranging from 550 hp to more than 750 hp. Final output always depends on engine condition, the fuel system, cooling and, above all, engine-management calibration.

Please note: An upgraded turbocharger should always be paired with professional ECU calibration. This allows the turbo to operate correctly and deliver its full potential.

How the exchange core and deposit work

I will send my turbo first: After ordering, you will receive a return label for sending your turbo to us for upgrading. The work normally takes around 1–2 weeks after a suitable core has arrived.

Complete turbo / Core deposit: You receive a complete turbo without sending yours in advance. You may return an undamaged original core to us within 14 days of delivery, after which we refund the price difference. If you wish to keep the original turbo, simply do not return it.

Tip: Ask us for the required gaskets, bolts, oil lines and other installation parts. A new turbo should not be installed with a restricted oil line or leaking seals.
