If you are running a turbocharger on your vehicle, it is absolutely crucial that you have all the correct components for the turbo to proper functionally. One of the most important parts of your turbo system is the wastegate. As your turbo builds up pressure, it is the job of your BMW Z3 wastegate to divert exhaust gases away from the turbo to prevent over boosting. Here at Andy's we have a great selection of BMW Z3 wastegates. Whether you want an all-out racing setup or something more suitable to daily driver use, our offering of BMW Z3 wastegates from all of the leading brands is sure to have you covered.

The wastegate is actually a flapper valve that mounts on your turbo setup. It is controlled by an actuator which is set to a predetermined boost level. When that boost level is achieved the actuator opens the wastegate and redirects exhaust from the turbo impeller straight into the exhaust system so that the turbo slows down and does not over boost. If the turbo were to over boost it would cause all sorts of problems from a blown head gasket to a completely grenaded motor. It is important that you make sure you have the right BMW Z3 wastegate setup for your turbo if you want to keep your motor healthy.

Q: How do you install a wastegate?
A: Wategates are mounted onto the turbo manifold by using a flange. Basic bolting of it is needed for installation.

Q: What is a wastegate? Why buy a wastegate?
A: A wastegate regulates boost by allowing excess exhaust pressure to bleed off. Wastegates generally come in two different types. The first is an internal wastegate, which is controlled by a wastegate actuator and bleeds directly into the exhaust system. An external wastegate is controlled by a boost controller and can be directed to bleed either into the exhaust system or directly into the atmosphere. It's mounted wherever there's space for it. External wastegates can handle more boost, but can be too big to fit in the space next to the turbo.
