Boost Lab BL78R Ball Bearing Turbocharger

This turbo features a newly designed Boost Lab Point-Milled Billet 7+7 Blade Point-Milled 78mm 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 ported anti-surge 4" Inlet / 3" Outlet compressor housing. This unit is available in Journal or Dual Ball Bearing. The Boost Lab Billet BL78R 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.
