sorry guys to bring this old thread up again, but now it still leaks a small amount of oil out of between where the turbine housing goes to the center housing, and i'm still not running a restrictor? where's the cheapest i can get one at? the turbo supposedly is a ball bearing, but idk. it spins for a while after i turn the car off, at least a good 20 seconds or so. also, the turbo is loud as hell!! not like it going bad, just while ur driving. it sounds like a diesel turbo, lol u can definately hear it.
