Inside Line takes the NISMO 370Z to Willow Springs for a performance test. Just to recap, Nissan has raised engine “output to a nice round 350 hp, but you’ll have to rev the mill to 7,400 rpm to access it.” Video after the break. Click here for first picture in gallery.

A recalibrated ECU and true dual exhaust (difficult to accomplish with this rear suspension configuration, we understand) are solely responsible for the additional power and torque.
