We report, as a part of a long-term study of IR mergers and IR QSOs, detailed spectroscopic evidences for outflow (OF) features in nearby IR mergers/QSOs (with low and extreme velocity OF, LVOF and EVOF, respectively). We found EVOF in IRAS 01003-2238, 11119+3257, 13218+0552, 14394+5332, 15130-1958 and 15462-0450. The low velocity OF components were detected mainly in objects with starburst processes. Meanwhile the EVOF were found mainly in objects with obscured IR QSOs plus strong starbursts. HST images of IR+BAL+Fe II QSOs show in practically all of these objects ``arc or shell" features probably associated to galactic winds (GW) and/or merger processes. We present also new results of a study of the morphology, kinematics and ionized structure of IR mergers/QSOs with GW. This new study is based mainly in INTEGRAL two-dimensional (2D) fibre spectroscopy (obtained at La Palma 4.2 m telescope).
