turbo is a tc05-10a non-wastegate sent it out for a rebuild, there was lots of play in the spinny thingy, and it was leaking oil into the exhuast. before the rebuild i was making 7lbs ish.
The turbo shop had to replace the center housing as well as the seals. I installed it, it spins, but no boost at all, the gauge doesn't move.
The gauge is ok, i checked it with 10lbs of compressed air, there doesn't appear to be any exhuast leaks.
The only thing done while the turbo was out was to fix an exhaust leak about a foot after the turbo. Could this be causing back pressure and not letting the turbo spool? could the turbo place have used wrong parts? Am i an idiot?
