The Ultimate Mitsubishi Dual Port Fitting Guide

Turbosmart Blow Off Valves - BOV5 Range

Drive Your Ambition with the Mitsubishi Dual Port

Mitsubishi Dual Port

We demonstrate how easy it is to fit the Turbosmart Mitsubishi Dual Port onto an Evo. We used an Evo X for this video, but the Turbosmart Dual Port also fits Evo VI, VII, VIII and IX, and the Ralliart Colt.

SmartPort Technology

The SmartPort is an innovative Blow Off Valve. It combines 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 as a bypass AND vent to the atmosphere valve. It also eliminates stalling and greatly reduces the chance of low-speed compressor surge. In addition, SmartPort’s unique lightweight piston is made from aerospace alloy. It has a military-spec coating. Resulting in quicker valve response, better sealing and superior durability.

Benefits Include

  • A direct fit upgrade for the factory BOV on EVO IV to X.
  • Staged dual ports allow bypass and vent to atmosphere operation in one valve.
  • Smart Port trumpet eliminates stalling. This allows smooth integration with the car’s factory engine mapping.
  • A Milspec, lightweight, aluminium piston. This provides excellent valve response with prolonged piston life.
  • All billet CNC construction and attractive anodized finish.
  • Australian-owned and manufactured. Assembled and validated in-house at Turbosmart HQ.
