One of the most important components in a well designed turbo kit, is a properly sized wastegate. Too small of a wastegate can cause boost creep, while too large of a wastegate will increase boost lag and decrease performance. Our external wastegates are made from the highest quality materials to assure both stability and durability in a turbo charger’s boost control. We have many options for you when building a turbo kit or if you are just changing your existing setup. This is one of our quality wastegates that can be used to control boost pressures. Our wastegates include spring(s), hardware, gaskets and flange(s). Please make sure it is correct. We believe our items are so outstanding. All products are quality checked. Otherwise deal is final. We will be happy to resolve any issues you may have in a cordial and friendly manner. We appreciate your Postive Feedback, and will do the same in return.
