This is a garrett t-3 turbo .42 on the compressor side and .48 on the exaust side. It is used but in great condition. The shaft has very little play, spins freely, and has never made contact with the housing. It has an internal wastegate that is adjustable from 6 to 12 psi and more is aquired via boost controller as the turbo will put out 15 psi efficiently. I want $265 + shipping.email me with questions or for pics.
