Nice! I find these to work even better than the skateboard bearings as the allow for slight misalignment without binding.Spherical Bearings, 8mm ID, 22mm ODhttps://www.mcmaster.com/2995K32
68HTA is a fantastic turbo for anything up to 450whpIf you go the Holset route just remember they’re physically large and they like high boost pressures to get into their efficiency range and make any power.
Buy a used FP turbo then. I’ve seen greens and reds go for $400-$650 fairly often. And if he can’t afford that then he can’t afford the clutch and fuel upgrades that go along with it either.
