BNR ST770 Turbo Kit for 2013-2018 Ford Focus ST

NEW BNR ST-770 Turbocharger is available for PRE-ORDER! Shipping of turbochargers will happen approximately middle of October 2025!

The BNR ST-770 turbocharger upgrade is intended for cars with auxiliary fuel systems and built bottom end. This turbo is good for up to around 580-600 WHP (more power is possible with a more efficient cylinder head). This upgrade will spool similarly to the ST71 but nets around 100 more peak HP when maxed out. The 770 has a German made ceramic dual ball bearing system that is reliable under extreme conditions! We also include a .038” restricted banjo bolt to eliminate oil feeding issues that journal bearings sometimes have when the engine isn’t ventilated properly.

If you currently have a BNR turbo, we can sell you just the turbocharger for a discounted rate. Please contact us by phone if you request this option!

Fitment of the BNR-770 may need minor clearance on the axle mount and will need a intake coupler to adapt to your intake system. Unit pictured has an inlet extension which will be removed when we start shipping out units!
