  • Turbine wheel: 55mm x 60mm gt3071 turbine
  • T2 .64 turbine housing (from nissan sr20)
  • .48 compressor housing (i have no idea what this comp cover came from)
  • Garrett Ceramic Dual Ball Bearing
  • Trask internal wastegate
  • HP Rating: 400+ Hp and 600 CFM

The previous Trask turbo specifications are:

  • Turbine wheel 47mm x 53mm
  • Compressor wheel 45 x 60
  • HP Rating: 165 hp

It looks From this picture that Trask Performance does do garrett ball bearing upgrades, but im not sure what size. Here is a picture of a To4b cover that they used, with this cover I could have machined it all the way to a 3076 or a gtx3582r. But we were just trying to make 200 hp with our build.
