Turbo upgrade options for 2.0 TD

[jackbombay]

Since I am going to rebuild my Audi 2.0 TD I was considering a cheap turbo upgrade. Does anyone know what turbo came on the 2.0? There is a Volvo 740 TD at the wreckers near here and I was thinking that turbo might be a relativley easy upgrade. Where can I find out which turbos came with these cars? And just as importantly is the bolt pattern the same.

  Thanks, Jack

BTW my intention is to run 15-18 PSI through an intercooler once the engine is completed. Stock the current turbo pushes 9-10 PSI, no IC.
