Yeah, the ones Jackson Diamond said are Ball bearing. You might whant to look into an Innovative Turbo also. Contact Frank and talkt o him about them. His screen name is cnynracer1 . Good Luck Brian! I'll have to come up for a ride in that beast when its done too!!
i finally had a chance to review some of my data logs after a little more street tuning. at around 3500-4000rpm boost comes on real quick . the turbo is one of our off the shelf non ball bearing T3/T67 with a .63 AR HPC coated turbine 4 bolt housing with a stage 5 wheel.
