I read somewhere it's a 3 day turn around too so factor that in. This doesn't include putting the turbo back on the car btw.
When I did the dump pipe on my stag it was easy enough but some of the studs were a bit tough to do, Also my turbo had half a mil of play so 66yo yours sounds normal for the KM's you've done. I would suggest looking into a hi-flow in the near future though before your hairdryer grenades itself.
P.S. YES that stupid f*cking c*nt engineer that designed that f*cking heat shield should've been taken out and shot!
