When Turbosmart began making performance products back in 1997, a great amount of effort was put into the design and manufacturing process to ensure our products created a new standard. More hand-crafted than mass-produced, Turbosmart products quickly gained acceptance within the performance community for their quality and reliability. Coupled with extraordinary service and after-sales support, Turbosmart quickly became one of the most sought-after names in the industry. Not much has changed since then. Although our product line and the company itself have grown considerably, the products are still designed and manufactured in our factory in Sydney, Australia, using the same tried and proven formula of innovative design, strict quality control, and rigorous testing. We have invested in our research facility manufacturing equipment and staff training to ensure our products continue to perform up to and beyond your expectations. At Turbosmart, we do not believe in cutting corners and half-measures. We do not accept anything short of perfection - and neither should you. Behind every Turbosmart product stands a long and rich racing history. While a majority of Turbosmart products are used on street cars, their design and testing procedure is identical to the high-end purpose-made racing products. Before reaching the consumer, Turbosmart products are subjected to a range of tests performed in the most demanding environment, the race track.

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.

This Part Fits:

The Smart Port is an innovative Blow Off Valve combining advanced design with precision CNC machined billet components. The valve works using two staged ports and a one-way valve on the trumpet outlet. This enables the Smart Port BOV to work like both a bypass AND vent to atmosphere valve in one while also eliminating stalling and significantly reducing the chances of low-speed compressor surge. In addition, the Smart Port's unique lightweight piston is made from aerospace alloy with a military-spec coating, resulting in quicker valve response, better sealing and superior durability.

• Smart Port trumpet eliminates stalling and allows smooth integration with the car's factory engine mapping
• A Milspec, lightweight, aluminum piston providing excellent valve response and prolonged piston life
• Staged dual ports allow for bypass and vent-to-atmosphere operation in one valve
• Manufactured, assembled and validated in-house at Turbosmart HQ
• All billet CNC construction and attractive anodized finish
• Direct fit upgrade for the factory BOV on EVO IV to X
