The Impreza platform is well catered to by Turbosmart. From mild, bolt-on mods, through to full blown, high horsepower race builds there are Turbosmart products to suit every Subaru enthusiast’s plans.
BOOST CONTROL
The simplest and most cost-effective way of increasing the boost is via a Gated Boost Controller Valve (GBCV). Easy to fit and set, a GBCV offers a simple boost control solution if you’re after a mild boost increase while running a factory turbo. Once fitted, you simply set your boost and forget it. The boost can be adjusted under the hood (Boost Tee) or from within the cabin (In-Cabin and Dual Stage). Turbosmart offers three types of GBCVs:
Boost Tee
The Boost Tee is an ideal entry-level boost controller. It’s inexpensive and easy to fit. The boost adjustable from under the hood with an accurate, proven Detent System. Set your boost and forget it – it’s that simple!

Suitable for all Subaru WRX, STi, Liberty/Legacy and Forester models.
In-Cabin
With the In-Cabin you can set the boost from the driver’s seat. Using the same proven Detent System as the Boost Tee, In-Cabin allows you to make boost adjustment on the run.

If you want to have more control over your turbocharger than the GBCVs can provide – the next step up are Electronic Boost Controllers.

Turbosmart offers two types of electronic boost controllers:
e-Boost STREET
