BL-R Series Turbos
The BL units with an "R" designation like the BL64R are a T04S based frame turbo. (This is the same frame that a majority of manufacturers use. PTE/HPT/Turbonetics, ect..). The BL-R units all come standard with billet compressor wheels and have the option for Journal Bearing or Dual Ball Bearing CHRA's. These units are direct fit for turbo kits that use PTE turbochargers as a baseline. And most T04S (S Cover) based turbos.
