Boost Controllers

Boost Controllers for Turbo Japanese and European Cars

Boost controllers give you proper control over wastegate pressure instead of leaving it to a factory actuator spring and a long rubber hose. This range covers manual bleed-style controllers, electronic boost controllers and the solenoids, fittings and hose needed to plumb them in. We stock the brands with a real track record in boost control because a cheap controller that creeps or spikes is a fast way to hurt an engine. Customers run them on everything from daily-driven Sydney turbo cars to circuit and time attack builds at The Bend.

Shop by Vehicle

Suits most turbocharged platforms, including Subaru WRX and STI, Mitsubishi Lancer Evolution, Nissan Silvia and 180SX (SR20DET), Skyline GT-R and RB-powered Skylines, Toyota Supra (1JZ/2JZ), Mazda RX-7 and turbo VAG platforms. Selection depends on whether your car uses a pneumatic actuator or an ECU-controlled solenoid, so check your setup before ordering.

Why Boost Controllers

A factory actuator opens progressively, which usually means soft spool and boost that drops off up top. A good manual controller holds the wastegate shut longer for a sharper ramp and flatter curve. Electronic units go further: closed-loop or duty-cycle based control, switchable boost levels, gear or RPM-based settings on the higher-end models, and a warning function if boost overshoots. Manual is simple and cheap to run. Electronic costs more and takes longer to set up, but it is far more repeatable across hot days, cold nights and different fuels.

Fitment & Installation

Most manual controllers are universal and plumb inline between the boost source and the actuator or wastegate. Electronic controllers need a switched 12V supply, earth, and a mounting spot for the solenoid away from direct exhaust heat. Many installers recommend fresh silicone or PTFE-lined hose and good clamps at the same time, since old hose is a common cause of boost creep and inconsistent readings. Any boost increase should be backed by a tune and appropriate fuel, and on stock turbos it pays to know the safe limit for your platform. Emissions and compliance rules vary by state for road-registered cars.

FAQ

Manual or electronic, which should I choose?
Manual suits a single boost target on a mostly stock or lightly modified turbo car. Electronic suits bigger power, multiple boost settings or cars that see track use in changing conditions.

Will a boost controller add power on its own?
It changes how and when boost arrives. Any real power gain comes from running more boost, and that needs a tune plus fuel and supporting mods to be safe.

Do these work with a factory ECU?
Manual controllers can work on some cars, but many modern factory ECUs run closed-loop boost control and will fight a manual bleed or throw a fault. Electronic controllers or a tune are the better path on those platforms.

Does the collection cover fittings and hose?
Yes, boost tees, fittings and hose are listed alongside the controllers so you can complete the job in one order.

Do you ship Australia-wide?
Yes, we ship to all states and territories, including WA and regional addresses.
