I run an ebay turbo on my rb30.
And I don't get the anti-china thing? If those guys can accurately put together the thousands of precision bits you are typing on, they they can build a big cast fan.
Yes my turbo is a bit laggier and not as efficent as some, but it delivered my goals for a street motor at a good price. And it might not last as long, but I can replace it 5 times before its worth buying a garrett.
BTW on custom race turbs from Garrett are built in america. Everything else is built in a third world factory just like your nikes
