.74MM B2 Frame Turbine Housing By BorgWarner
The EFR (Engineered For Racing) turbochargers from BorgWarner offer an unprecedented combination of advanced technologies. Low-weight Gamma-Ti turbine wheels and shaft assemblies for quick boost response Patent-pending dual ceramic ball bearing cartridges for more thrust capacity, durability and turbine efficiency at low expansion ratios Stainless steel turbine housing for increased efficiency, improved durability and corrosion resistance Range of units supporting 225 to 1,000 horsepower per turbocharger.
EFR turbine wheels are made from titanium aluminide (or Gamma-Ti). Not quite ceramic and not quite metal, the material is very light-weight and demonstrates excellent strength at high temperatures. Because EFR turbine wheels weigh 50% less than typical turbine wheels, less energy is required to spin up the wheel, allowing the turbocharger to respond faster. BorgWarner EFR turbochargers also feature the newest ''super back'' and ''fullback'' turbine designs for high-boost, high-efficiency applications.

Map was great to answer all my questions and point me in the right direction with my build and parts. If Map website doesn't have what you need or you seem unsure in your direction, just contact them and they will set you straight. I originally didn't know where to go with a turbo set up. I had thought bigger was better (stock block), but after conversating with Adam we decided on a 8474 and the power band is perfect for my application. Also the product had no issues and was properly packaged and wrapped. Keep in mind you still need hardware to assemble the supercore to the turbine.
