We study isospin effects in semiperipheral collisions above the Fermi energy by considering the symmetric {sup 58}Ni+{sup 58}Ni and the asymmetric {sup 58}Ni+{sup 197}Au reactions over the incident energy range 52A-74A MeV. A microscopic transport model with two different parametrizations of the symmetry energy term is used to investigate the isotopic content of pre-equilibrium emission and the N/Z diffusion process. Simulations are also compared to experimental data obtained with the INDRA array and provide information on the degree of isospin equilibration observed in Ni+Au collisions. A better overall agreement between data and simulations is obtained when using a symmetry term that linearly increases with nuclear density.
