Default Numerical integration of Spalart Allmaras turbulence model

RenardP is on a distinguished road

What is the more reliable technique to discretize the compressible Spalart Allmaras turbulence model on an unstructured grid ? My solver uses 2 order upwind for the convective fluxes and 2 order centered formulas for the viscous fluxes. For time integration I use a 4'th order RK scheme.
