I have a turbonetics cpt62 from cottons, bout 20k miles on it, nice shape. Its (to the best of my knowledge) single ball bearing, 4" in, 2.5" out, a/r .63 exhaust housing, went 10.7 @126 on a sloppy tune mild build full weight car, would definately get you to mid 10's with a good converter and tune. Needs about 3k stall speed, spools pretty quick. 500 bucks and its yours, it was over 1200 new in 08.
