ive tried to get a rebuild kit from a turbo supplier/repaier....he rekons that the t2/t25/t28's balances are very fiddly, so they dont even overhaul them they send them out to a place that has a static balancer.....but i do rekon you can get kits from them, and as long as your only taking off the housings and not dissasembling the core you dont have to worry about the balance, MTQ turbocharges is the company's name they have branches in every state (im pretty sure)
