We propose a model for the large NSU(N) lattice gauge theory, obtained by introducing twisted boundary conditions on the Eguchi-Kawai model. The simplest version corresponds to changing the sign of the coupling β in the EK model. The Schwinger-Dyson equations of our model are equivalent to those of the Wilson theory. We argue that (U(1))4 symmetry is not broken. Monte Carlo data indicate that our model reproduces the main features of Wilson theory.
