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.  The 770 also comes with a manifold spacer to keep you from having to clearance on the axle mount.  We also include a separate DTM wastegate actuator assembly for those that want to maximize the internal wastegate performance.  Directions are included with the actuator for preloading.
