BorgWarner Super Core EFR B1 6258 Turbo (11587105002)

11587105002

The BorgWarner EFR 6258-G 49mm Supercore is the smallest and fastest spooling turbocharger in the EFR lineup, thanks to its low inertia Gamma-Ti turbine wheel, which is 50% lighter than traditional Inconel wheels. It delivers a single turbo output range of 225-450 HP and 450-900 HP in twin turbo applications. Featuring a 62mm compressor wheel, the EFR 6258-G offers a large map width for exceptional power potential, even at high boost levels. The low inertia 58mm Gamma-Ti turbine wheel is perfectly matched with the forged milled aluminum compressor wheel for maximum response and fast spool. Its compact EFR compressor housing allows for fitment in the tightest engine bays.

Designed and produced in the USA, BorgWarner is a leading manufacturer of turbochargers worldwide!  All BorgWarner turbochargers are produced with quality and performance in mind, and this is why the brand has more than 100 years of boosting heritage.
