    Engine Code: VR38

    Peak Power: 480ps/6,800rpm

    Peak Torque: 58.0kgm/1,700 - 5,600rpm

    Details: VR38 Twin Turbo V6
    The engine powering the new GT-R will be extremely lightweight compared to engines of similar capacity and complexity. Titanium intake valves and magnesium alloy exhaust valves will be used as well as a version of the new VVEL (Variable Valve Event and Lift) technology as used in the V36 Skyline Coupe. Red line is from 7,600rpm, with a 7,800rpm rev limit. Even after peak power has been achieved at 6,800rpm, 90% of maximum power will still be available from 6,800 - 7,500rpm with the power curve staying virtually flat from 6,800rpm to red line. The secret to the GT-R's speed is in it's ability to obtain peak torque at such low revs, as well as a very usable spread of power right across the rev range. There is even mention of the engine being designed for a maximum power output of 600ps, but being detuned to 480ps for production.

    The engine powering the 2008 GT-R is not part of the VQ family. Holiday Auto have reportedly been told that the engine appearing in the new GT-R has a 'VR' designation, leading them to believe that it has a strong connection to the VRH35L from the Nissan R390 that contested the Le Mans 24 Hour endurance race!.
