Does this look like a good turbo build?

Why not ask about what the dealer wrote. You shouldn't have to "deduce" anything. If they don't know about the car's injection system, they probably don't know very much about ANY of the car.

So, how about some real questions then.

What turbo is it using? Is there any play? How many miles on the turbo?
What management is being used? How and where was the car tuned? Are there dynos? How much power is it making? What boost level is it running? What is the compression in each cylinder? What do the plugs look like?

And so on, and so on.
