These Turbonetics Evolution series wastegates redefine performance for externally mounted boost controls. Utilizing the latest technology in flow design and materials, they feature an investment-cast 304 stainless body designed with computer flow analysis, a "Nitronic 60" stainless steel one-piece valve, and a polished aluminum billet cap. The wastegates' new smaller size is designed to fit into the tightest turbo systems. They're also fitted with a rolling-type diaphragm and floating valve seat, able to comfortably handle 400+ hp.
