How to Install the Skyline Boost Controller
Give your Skyline more performance with a boost controller upgrade (turbo image by Elijahu from

The Nissan Skyline developed a huge following in its native Japan and overseas due to appearances in the "Gran Turismo" line of video games. The relatively small RB series 2.6L-6-cylinder-DOHC (double overhead cam) turbocharged motor was mandated to have a maximum limit of 276 horsepower, however the real figure was closer to 320, as several GTRs were tested on dynamometers to acquire accurate baseline readings. The GTR's little brother (GTS-T) has a smaller motor but still manages to produce 215 horsepower in stock trim. Both of these engines run conservative boost levels from the factory, and can be fitted with a simple boost controller upgrade to unlock hidden power.

  1. 1

    Connect one end of the boost controller barb to the wastegate actuator with a vacuum hose.

  2. 2

    Connect the other side to the boost outlet source, near the turbo compressor intake.

  3. 3

    Attach the MBC with zip-ties (included in the kit) away from the turbine housing and exhaust manifold.

  4. 4

    Turn the knob on the controller to adjust boost psi in the desired direction, and perform a full throttle run to get a reading on the boost gauge.

  5. 5

    Fine-tune the controller to reach target level (no more than 12 psi on the stock Skyline fuel system).

Tips and warnings

  • Supporting modifications such as intake, exhaust and bov (blow off valve) upgrades, will further increase power gains and minimise turbo-lag.
  • Increasing boost past factory programmed settings can cause serious engine damage; proceed with caution.
  • Use a private road or track for all testing.
