Turbosmart
Turbosmart has been making turbo management products in Sydney, Australia, since 1997, and its range here is about controlling boost and fuel pressure. It covers blow-off valves (Kompact, Kompact EM, Dual Port, Plumb Back and RacePort among them), internal wastegate actuators (IWG) and external wastegates in several sizes. It also has electronic BoostGate units, manual and electronic boost controllers, and fuel pressure regulators. TS-1 turbochargers, V-band flanges, oil lines, fittings and gaskets complete the list.
A good share of the range is service parts: replacement diaphragms, springs in different pressure ratings, O-ring kits, solenoids and weld flanges. These let you rebuild or re-spring a valve rather than replace it.
Turbosmart parts are sorted by model and specification, not by car. For valves made for a particular car, the title gives the application; otherwise choose by flange size, spring pressure and fitting.
The other large range in the Turbo section is turbochargers and housings. Turbosmart is where to look for the valves, actuators and controllers that manage the boost those turbos make.

Description
Turbosmart Upgraded Wastegate Actuators have been developed to provide maximum possible boost response for your factory frame turbocharger. The Turbosmart IWG75 Series of upgraded Actuators benefit from an increased ‘Working Ratio’ over the factory equipment resulting in improved boost response, throughout the RPM range.
This Improved ‘working ratio’ is achieved through an increase to the effective surface area of the diaphragm & revisions to the actual springs fitted resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive.
Upgrading with the same base pressure as factory, you can expect a broader boost & torque curve through peak boost being achieved earlier in the RPM and being held longer, into higher RPM. These improvements can be amplified with higher base pressures, however tuning & recalibration is likely required.
Features
Proprietary Silicon Nomex Diaphragm
Choice of Springs from 3psi to 26psi (Optional)
High Grade Billet Aluminum Construction
Stainless Steel Rods and Clevis
Turbosmart Unique Locking Collar System
Suitable for Polaris RZR Turbo and Turbo S vehicles from 2016-2021. Please look up the vehicle application guide for more detail.
