  • Utilizing a uniquely engineered ball/spring mechanism combine with an adjustable bleed valve, the BC-HPBC allows you to spool your turbo to full boost up to hundreds of RPM faster than stock! The adjustable bleed mechanism lets you minimize the massive boost "spike" that can occur with poorly designed ball/spring manual boost controllers.

  • Winner of the Global Press Award at the 2007 SEMA Trade Show, Turbosmart's e-Boost2 allows the user to control, monitor, map, and compensate boost. But e-Boost2 is a lot more than just a boost controller – it can also control water spray, methanol, or nitrous injection, manage shift/warning lights, and read/monitor RPM. The e-Boost2 has been effectively controlling up to six stages of boost by gear, boost by rpm, boost by time, and more, all the way up to 60 psi for over a decade. All in a self-contained gauge pod, with an overboost shutdown to keep your motor safe from harm. While e-Boost2 is fitted with state-of-the art software, it has been designed to be easy and logical to use.

  • The GrimmSpeed Boost Controller Solenoid is designed to work with your factory computer (requires tuning). It will not reduce the life of your factory computer because it is designed to draw the same amount of power as the factory BCS but flows better and reacts faster. It plugs in and requires no splicing nor soldering. With the included bracket, you can bolt it in, plug in the connector, and start tuning for faster boost response and increased boost pressure. Planning on returning the car to stock? Simply reverse installation.

  • If you've been in the Subaru game for long, you're probably well aware that a 3-port Boost Control Solenoid (BCS) is considered by most to be a 'must have' upgrade before having your car tuned. GrimmSpeed has become the most trusted brand in the BCS market, with tens of thousands of their boost control solenoids in operation today across the globe.

  • GrimmSpeed introduces the most complete and easy to use 3-port electronic boost solenoid available on the market. This GrimmSpeed aftermarket boost controller allows you to raise the OEM boost levels in a quick and efficient manner. If you try to raise the boost on the weak OEM boost solenoid it will start to become unpredictable and unable to maintain proper and safe boost levels. Using this solenoid you are able to spool your turbo quicker and maintain a rock solid boost level. GrimmSpeed has made this solenoid to withstand up to 120 PSI.

  • We are proud to present the GrimmSpeed Manual Boost Controller, the most refined manual boost controller available on the market today. For over a year, GrimmSpeed worked hand-in-hand with tuners across the country to develop this boost controller. The GrimmSpeed MBC allows you to raise OEM boost levels in a quick and efficient manner through superior boost range and ultra-fine resolution (.25 PSI/click). Adding the MBC to your car will result in quicker spool up, quicker response, increased horsepower, and increased torque.

  • GrimmSpeed has introduced the most complete and easy-to-use 3-port electronic boost solenoid available on the market. This GrimmSpeed Boost Solenoid allows you to raise the OEM boost levels in a quick and efficient manner. If you try to raise the boost on the weak OEM boost solenoid, it will become unpredictable and unable to maintain stable and safe boost levels. Using this solenoid, you are able to spool your turbo much quicker and maintain a rock-solid boost level. GrimmSpeed has made this solenoid strong enough to withstand up to 120psi.

  • AEM's TRU-BOOST Gauge-Type Controller is an electronic boost controller that combines the simplicity of a manual boost controller with the added ease of adjusting boost levels through a gauge interface. There is no external interface required for set up, and it is fully functional right out of the box. There are no gimmicks or special software programs included. If you want more boost press the button on the right of the gauge face, and if you want less boost press the button on the left of the gauge face. It's that simple, and it just works!

  • The Turbosmart E-Boost STREET is an electronic boost controller aimed at the street performance market. It features many boost control capabilities found on its big brother the e-Boost2, continuing the e-Boost tradition of providing class-leading boost control, value for money and no-nonsense features. New features include a 40 PSI max boost operating pressure and an auxiliary output.

  • Turbosmart's Gated Boost Control Valve is the easiest and most cost-effective way of controlling the amount of pressure going to the wastegate. All Turbosmart Gated Boost Controllers are manufactured from high-grade brass and aluminum, and are renowned for their easy installation, operation, stability, and durability. The extensive range covers all applications from mild street-tuned engines to purpose-built race power plants.

  • Fast boost response with two adjustable boost levels. Toggle between high and low boost on the fly. This is the ideal replacement for factory boost controllers. Both high and low boost settings are fully adjustable. All Turbosmart Gated Boost Controllers feature their exclusive gate feature which minimizes wastegate creep and can result in quicker spooling up to 800 rpm earlier in the rev range – this means you can increase the performance and response from your engine without raising the maximum boost level.

  • Smaller and lighter than other Manual Boost Controllers on the market, the Turbosmart Manual Boost Controller allows to you to simply set your boost and forget about it. Boost is adjustable from under the hood with their accurate and proven detent system. It is easy to install and adjust, while Turbosmart's gated system brings boost on faster.
