We present an improvement of the recently developed effective interaction method for the hyperspherical formalism (EIHH). The method is extended to include contributions of three-body effective forces and the non adiabatic kinetic energy term. It is shown that the rate of convergence is improved considerably, opening up the way for application of the method to realistic 6-body calculations.
