Ask a Question
  • I have a s366 borg Warner turbo on a 6.5” pedestal and wanted to know if just running a single turbo would be fine with this kit? I plan to go with twins in the future.

    On Single chargers use this bridge
    It can wil be in the way of a twin turbo though..... The Twin style HSP bridge is for a stock turbo and with compond on top of it. The twin style HSP bridge will be a pain to try to route intake tube to single s366.
