When I re-installed my stock turbo (after BHG work), I didn't put my car in a lift. I did all the work over the engine; not easy getting the oil lines back in place but I took my time and familiarized myself how bolts go back in. IIRC, there's one bolt that I can't see when installing but knew where it goes and had to put in in by feel, if that makes sense.
Good luck.
Captain, thanks for posting that pic of the gasket. I have that laying around from my head gasket replacement kit and didn't know what the heck it was for. (I didn't remove the elbow after the turbo .) Now, I know what it's for, lol.
