I have a set of sport 600's w/upgraded thrust bearings ( 360 degree ) and carbon seals. These turbos have a 1year warranty. The manufacturer / distributor I used works with the major vendors on this site. The turbos are ready / available now and I am letting go @ $2200. I also have a set of 3 inch 4bolt random tech downpipes with egt bungs welded in for another $100 that I will throw in. Total cost = $2300 plus shipping. Serious inquiries only. These turbos allowed me to reach 604rwhp on the dyno with minimum lag. See profile for dyno results.
