PT61, T350 turbine wheel, T3 .63 A/R turbine housing, with a 4" / 2.5" compressor housing. Turbo has oh...about 30-50 miles on it and ZERO hard driving at all (IOW, it's still new or next to new). Would like to get $750 for it, but will entertain offers. Only reason I am selling is to go bigger, this turbo is supposed to be capable of ~550 HP IIRC, I will probably be ordering up a PT-67 to replace this one. When I was driving around with this it would make 20 psi by 4000 RPM on a 2.0 liter WRX. [email protected] 701.541.3484 -Chuck
