Thanks so much to Peter and Dave for the information.
Having studied the Vadis instruction that you sent Dave, I still think I am missing something. I looked at the car again and couldnt see what they meant by the lower crossmember.As for 6 hours, well I think I would struggle at 16 hours!
You cant see anything from underneath, it looks like its maybe a 'Tom Cruise' mission impossible job dangling from the ceiling to remove them from the top!
Maybe its one of those jobs that just looks worse than it actually is?
I'm not even sure yet that it needs a turbo! but from what I've seen so far it all points to that. I dont know if I really want to do it, I'm too old to be lying across an engine block looking like my cocks caught in the radiator filler!

Colin.
