no need for ball bearing IMHO...Precision does make waterless ball bearing now. A JB billet wheel is plenty. I have the Pricision 6768 CEA(billet) t4 with a .96AR...935hp rated. 67mm is a great startinig point turbo. A 71mm is very nice too. I try and make 750rwhp with a 67mm on a 2v.

a 76mm is fine with a built longblock and turbo cams and looking for over 800rwhp. But a 67-71mm is plenty for most people with mod motors.

a guy with my exact turbo just BB(mine isn't) with just a forged shortblock with near stock CR made 499rwhp and 5xx rwtq at 13.7psi on a 2V motor. Imagin that on a 3v engine...quick spool and TONS of torque without the wieght/more piping for cracks/leaks. I would be a lot faster...
