We start with a Tomioka Racing 3 bolt uppipe then modify it to accept the Turbosmart wastegate of your choice. OEM quality multi-layer-steel gasket sets available in full kit (2x Head to manifold, 1x 3 bolt manifold to uppipe, 1x uppipe to turbo, 1x turbo to downpipe) or basic kit (1x 3 bolt manifold to uppipe, 1x uppipe to turbo) Our kits feature Turbosmart wastegates which utilize the smallest light-weight diaphragms for fast valve response. Easy to swap interchangeable springs make dialing in boost a breeze. All wastegates come standard with a 7psi mid spring with additional springs available for purchase.
