  In this paper we explore an evolutionary Unified scenario involving super
massive black hole and starburst with outflow, that seems capable of explaining
most of the observational properties of at least part of AGNs. Our suggestion
is explored inside the expectations of the Starburst model close associated
with the AGN where the NLR, BLR and BAL region are produced in part by the
outflow process with shells and in compact supernova remnants. The outflow
process in BAL QSOs with extreme IR and Fe II emission is studied. In addition,
the Fe II poblem regarding the BLR of AGN is analysed. Neither the correlations
between the BAL, IR emission, FeII intensity and the intrinsic properties of
the AGN are clearly understood. We suggest here that the behaviour of the BAL,
IR and FeII emission in AGNs can be understood inside an evolutionary and
composite model for AGNs. In our model, strong BAL systems and Fe II emission
are present (and intense) in young IR objects. Orientation/ obscuration effects
take the role of a second parameter providing the segregation between Sy1/Sy2
and BLRG/NLRG.
