It depends on the amount of use of that stock fuel pump. IF you're using it with an FMU and stock injectors, your setup should come with at least an INLINE pump to ensure that the FMU can work properly. If not, I'd upgrade to a larger one if not now, than soon. If budgets are a concern, a larger used unit from a 3rd gen should be able to work for you.. But at around 100 bucks, if you can afford to go turbo, you can afford to get a better fuel pump..
