k27_turbo

i have a brand new kkk k27 turbo charger for sale, and apparently it is a direct upgrade for an audi k24 or k26 turbo. i am not familiar with audis, so bare with my limited knowledge. anyway, the turbo is a k27, suited for 550hp with a 68mm compressor wheel, and 75mm exhaust wheel. it is an oil cooled turbo, and has a split pulse design exhaust housing. there are numbers on the front plate (the blue one). they are (from top of plate to bottom): GROSSE: k27, ATL-NR.: EA503728800053 and AUSF-NR. 5327 988 6072. i am looking for $1300 firm on this turbo. cheers, nick.
