    external wastegate suggestions

    holset he351cw with aftermarket turbo manifold on 2.4L.

    planning on welding puck shut and using the external wastegate manifold mount. having a hard time trying to justify spending 250 on a tial. any other tested wastegates at a lower price available? what would you recommend for min spring pressure?

    After being very impressed with the Synapse Engineering synchronic bov, i would look at their external wastegate offerings. But, i am not sure of the cost matching that pricepoint.
    The bov has no diaphragm, and the wastegate uses the same technological design.
    If i ever need to use an external I will be trying one of theirs.
