History
Did you realize BorgWarner’s origins can take us back all the way to 1880? The BorgWarner we all know about today started in 1928. That’s a whole lot of decades in the industry. Currently, BorgWarner is a massive company, providing parts for car companies that need to work day in and day out. That same OEM reliability and quality standard reflect the same in their aftermarket options, with way more performance.

Product Details
The EFR 9180 is BorgWarner’s answer to the goal of a 1000hp capable turbo with unparalleled spool and response. Winning races is the purpose of this turbo. Honda’s Indycar Team, 3x World Time Attack Champions Tilton Racing, 2012 WTAC champs Nemo-Racing, FXMD NSX and many more – this turbo redefines what 67mm turbos are capable of. The EFR 9180 is the biggest, baddest, highest flowing turbo in the EFR family. Capable of a remarkable 94lb/min airflow and stable at high boost levels, the 91mm OD compressor measures 67.7mm inducer and is a 7 blade extended-tip FMW compressor wheel design. Utilizing the identical design and material turbine and compressor wheels as Honda’s IndyCar 2.2L single turbo engines, EFR 9180 is ideal for use as single turbo applications in the 700-1000hp per turbo range, or as very high power twin turbo applications >1000-1700+hp. Available with .83 a/r (undivided T3 IWG) or 1.05 a/r and 1.45 a/r divided twin scroll T4 housings (external WG). Ceramic Ball Bearing only, water cooling optional (recommended)
