I'm propper fucked off. I bought a Garrett GT28R brand new from the States last year, i've done about 6,000 miles, but have been running it at quite high boost (18psi - which it can't hold at the redline).

It's started smoking on the over-run. There is about 1mm in and out play on it, no side to side. The compressor wheels are fine and so is the housing. How much am I looking at for a re-build?
