I think what Scott is trying to say is fair enough really:
1. How much is the cost to single turbo a car that has had EVERYTHING done to freshen it up already (stem seals etc.) - IGNORE THE COSTS OF THE FRESHEN UP.
2. If the freshen up stuff (stem seals, nuts and bolts, gaskets etc.) had NOT been done, how much to do it all?
3. If spec prior to starting was not up to a high standard (J-Spec brakes, poor tyres etc.), how much to get it up to spec?
4. Any additional parts that would be nice but are 100% NOT NECESSARY (billet tensioners etc.), how much to add them as well?
That's how I'm reading it anyway.
