asking if a car can use a turbo without braking is a question that will need more information. You sould be safe a a low boost ~6psi, but if he is running stock internals or injectors on something more optimistic say 14psi, then it's a ticking time bomb. As a personal rule of thumb i try to stay away from modified cars, because usually thay have been abused, driven hard and put away wet, i always figure your better off getting a cheaper car and doing your own work to it, that way you get exactily what you want, and you know it's done right.
