This turbo features a newly designed Boost Lab Point-Milled Billet 6+6 Blade 76mm compressor wheel. This new design is extremely efficient at lower shaft speeds compared to other similar size units on the market. This translates into a stronger power band from mid-range rpm to the top-end horsepower.  A 10-blade 75mm turbine wheel drives this rotor assembly. This unit comes standard with a 4" Inlet / 2.5" Outlet compressor housing. Our Twin Hydrodynamic Journal Bearing with 360* Thrust CHRA is designed to handle high boost operation with ease. We are now offering a Dual Ball Bearing option for faster transient response and higher boost capability! The Boost Lab Billet BL-7675 is fully assembled and VSR balanced at our facility and all of our BL turbochargers come with an industry standard 1 year unlimited mileage warranty.  The BL-7675 GEN 2 turbocharger is typically in stock and ships same day.
