This page offers upgraded turbochargers for cars that came from Mazda, Mitsubishi, Nissan, Subaru, Toyota, and VW. If your car did not come with a factory turbo, we also provide GReddy Bolt-On Turbo Kits.

There is no doubt that turbocharging a car provides the very best bang for your buck in upgraded performance. The factory provides turbochargers on some models for the very same reason. It allows them to provide their customers with an engine that makes more horsepower than it would if not turbocharged, and it does so within the federal gas mileage and emissions standards.

As the owner of a factory-turbocharge vehicle, you were probably impressed with the horsepower your car provided when you first drove it. Now that the new has worn off, you're wondering what else is possible. Or, if you've had the misfortune of seeing your factory turbodrop dead, you may be curious if your hard-earned dollar might buy something better than stock now that you're forced to do something.

Well, wonder no more! The turbocharger upgrade kits offered on this page are made by GReddy® one of the worlds foremost authorities on aftermarket turbo applications. Each kit is designed to provide the precise turbocharger to give both dramatic increases in performance while maintaining drivability. In addition, many of the kits here include upgraded manifolds (some even stainless-steel turbo headers), upgraded wastegates, and more. Some even convert the stock dual-turbo systems to a single turbo. (Wait! Don't look like a newby and ask why anyone would want to go from two turbos to one. It turns out that you can make far more horsepower with a single big turbo than you can with the stock dual-turbo setup. Who knew?)
