So I have a bad turbo, lots of play in the shaft, resistance spinning. I am open to rebuilding (easiest if it works) or replacing. After searching here I am baffled by the array of possibilities. I want mild performance (at altitude) on a 3b. The present turbo says TD05-H re no KD 1900164. TD05-H seems to be the type or style of turbo, which could have all different internals, is that right? I have a stock flipped 3B exhaust, is there a known workable turbo which has that flange bolt pattern? I guess really, where do I start? Thank you!
