This item ships directly from BNR Turbo
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 flooding 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. Â Unit pictured has an inlet extension which will be removed when we start shipping out units!
