2009-2021 Nissan GT-R Mid-Cover Oil Passage Gasket Set by AMS Performance

Our 4.0 liter Big-Bore Engine adds displacement but in doing so maintains a great peak RPM capability by increasing bore and not stroke. The result is an increase in power without compromising RPM limitations. With proper tuning and supporting modifications the AMS Alpha Big-Bore Engine is capable to revving over 8,000 RPM!

In addition, we raised the compression ratio to further increase horsepower throughout the power band. This increase also produces more low end torque which considerably reduces turbo lag and improves boost response. By combining a larger bore size with an increased compression ratio we have achieved a 5-10% increase in torque and a 300-400 rpm improvement in turbo spool up time!

Features

  • 5-10% increase in torque
  • Balanced rotating assembly
  • 300-400 rpm improvement in turbo spool up

Benefits

  • Great peak RPM capability by increasing bore and not stroke
  • AMS proprietary components for the strongest, most advanced engine program available
  • Increased compression ratio for added horsepower and torque

Applications

  • 2009-2021 Nissan GT-R
