High performance natural aspiration power:
it is what defines the NSX. ScienceofSpeed introduces the
most complete engine tune packages available for the NSX. These stages emphasize maximum natural aspiration power with street
usability and durability. Increase power and revolutionize your NSX with our multi-stage
performance engine packages.
These stage packages are only examples of suggested product
combinations. Horsepower gains represent typical differences in peak
horsepower output when comparing a factory equipped 3.0L NSX and a 3.0L
NSX equipped with these engine packages and supporting intake / header /
exhaust.
These recommended stages included a package discount. |
