Caroline's 996 Turbo has just had the Akrapovic evolution system fitted and the condition of the turbos came up - at the last service Parr said they were corroded but they had seen far worse. As everything is now nice and easy to get at and undo is it worth replacing the turbos? Or leave them a year or two till they get really bad? Internally they are fine and the studs/wastegates/rods/oil pipes are fine.
I don't like the sound of 'the turbos are corroded' - yet the Porsche guys I talk to take it all in their stride.
I'm used to a Lexus LS that is hewn from granite, the exhaust still looks like new after 200k miles, the underside of the car has no corrosion yet the 996 looks quite, ropey, and that seems the norm. A bit like old British cars - as long as you look after them they are fine. No comparison in the driving - the Turbo is great fun, the LS a lovely waft.
So - replace the turbos now when everything is nice and loose - or wait till they get worse?
