  At CERN Linac4 is being com­mis­sioned as first step in the LHC in­jec­tor up­grade to pro­vide 160 MeV H ions. In order to fully de­ploy its po­ten­tial, the PSB con­ven­tional mul­ti­turn in­jec­tion will be re­placed by a charge ex­change in­jec­tion. An ex­pected bright­ness im­prove­ment of about a fac­tor 2 would then be dif­fi­cult to di­gest at PS in­jec­tion due to space charge. There­fore the trans­fer en­ergy be­tween PSB and PS will be in­creased at the same time from 1.4 to 2 GeV. This paper de­scribes the new PSB in­jec­tion sys­tem and the sta­tus of its test stand. Mod­i­fi­ca­tions of the PSB ex­trac­tion and re­com­bi­na­tion septa and kick­ers in the trans­fer line are shown. A new fo­cussing struc­ture for the trans­fer lines to match the hor­i­zon­tal dis­per­sion at PS in­jec­tion and the de­sign of a new eddy cur­rent sep­tum for the PS in­jec­tion are pre­sented.
