I currently have a bid on ebay for a TDO5H turbo and manifold. It does not have the exhaust flange/O2 housing on the turbo. Seller says its off a Starion turbo, but then says he thinks its aT3 From what ive researched the exhaust flange/O2 housing is the same as aT3. Any info on this turbo, no matter how trivial, would be much appreciated
