It's a Garrett 3788 Stage 3 water cooled ball bearing turbo. Housing size is 63.5/73.5/14. I've had this turbo for about a year, has around 10,000 miles on it and I've sled pulled with it about 6 times. It is still great for daily driving and towing being that it is the ball bearing style it still spools fast. I've ran 100 and 200hp injectors and comp box with it. It will bolt up to stock exhaust flange. It will fit 98.5-02 cummins 24 valve. I have also built a 4 inch hood stack pipe that bolts up to it. This turbo sells for around $2500 new. I'm wanting $1250 for it or $1400 with the hood stack pipe.
