    (0 reviews) Share it View Details

    Smaller, Lighter and Faster – Turbosmart’s turbocharger series has been developed to leverage modern materials, design and manufacturing techniques to create a turbocharger range that meets the demands of both motorsport, and performance enthusiasts alike.
    Every Turbosmart turbocharger comes standard with everything you need for installation, weld flanges, V-band clamps, gaskets, oil feed and drain fittings are included.
    The TS-1 series are oil cooled turbochargers with lightweight investment cast turbine housings, a proprietary bearing and main shaft combination which will provide transient response you never knew possible with the type of performance, quality, reliability and support you’ve come to know Turbosmart for.
    The ultra-low rotating mass of our unique bearing and shaft assembly is matched to aggressive compressor aerodynamics to ensure high levels of performance at lower shaft speeds which is mated with a unique turbine wheel to ensure power at high loads and flow is maintained.
    All Turbosmart turbochargers have been designed with an engine end-to-end approach aiming to achieve power through reduced back pressure and high performance turbines – while being smaller, lighter and faster in response than other solutions on the market.

    Dual Port Smart Port Nissan GT-R R35 Kit

    (0 reviews) Share it View Details

    As turbocharged performance cars go, the Nissan GT-R is a legendary giant killer. The R35’s twin-turbo VR38 V6 offers exotic-beating performance levels in a much more accessible package. Turbosmart has developed a range of products specifically for the R35 GT-R, and our commitment to this legendary nameplate continues with our latest SmartPort blow-off valve.

    The SmartPort is a revolutionary BOV design. The SmartPort’s drive-by-wire friendly staging technology works with the vehicle’s standard mapping to maximise the performance of the valve to deliver the best results for the car, giving you the response of a Plumb Back valve, with the high-performance benefits of a vent-to-atmosphere valve – a welcome improvement in a vehicle with such massive performance out of the box.

    The SmartPort’s piston is made from aerospace alloy with a military-spec coating, reducing its weight and friction and improving valve response and durability. With faster response and better sealing, the SmartPort allows quicker spool-up and better performance on the drive-by-wire GT-R while reducing damaging compressor surge.
