    Thumbs down Injector Size help Needed

    I am looking at taking the Riva 50 injectors from my ski as I am just about to fit a Mini Rude and a RRFPR. What I am asking is would I be better with Bosch 48s or Bosch 50's

    Set Up on Ski

    Riva ECU
    Riva 50's (to be changed)
    X-Charger(to be change to Mini Rude)
    Rear Air/4" Kanaflex
    XS Intercooler
    Up-rated Walbro Fuel Pump


    I am sure there must be a lot of you out there with something the same or have done in the past to what I am running.

    So do I need Bosch 48's or 50's

    I am running the Riva 50's now but i would hate for then to lock up, this is why I am looking at changing to the Bosch units. I have read on here the Bosch 48's are around the same flow as the Riva 50's. If I was to go with the Bosch 50's would this make the bottom end to rich?
