When Nissan offered their Series II upgrade package for the 2009 GT-R they improved the handling and added a few aesthetic pieces, but they forgot to increase the power. That is because the Japanese automaker’s motor sport division, Nismo, is offering an upgrade of their own. The Nismo power package consists of new engine and transmission software that offers more low-end torque and a higher maximum boost for more top end. They also raised the top speed to 199 MPH.
However, unlike the upgrade being offered by Nissan, you have to rent the Nismo package. The first two years of factory tuned GT-R fun will cost you $3,090; after that the lease can be extended for another year for only $330 more.
Seeing as the initial investment is about 10 times the cost to maintain the package, the Nismo power upgrade is an investment that is well worth holding on to.
