Thread: Wastegate Spring Fitment

  1. #1

    Cool Wastegate Spring Fitment

    Does anyone know if a wastegate spring that fits in a 40mm wastegate will fit in a 38mm wastegate too?
    I have a 40mm wastegate spring and am wondering if it will fit in a 38mm wastegate.

    I am going to guess you're referring to Tial Wastegates.

    Follow this link:

    Although the springs are indeed interchangeable, the same color spring will equal a different wastegate setting depending on the size of the wastegate. That link has the different pressure settings per wastegate.

    There are different charts per wastegate at the bottom. Just click and they'll open.
