New to the 2006 and newer 350Z models is the VQ35DE 3.5-liter V-6 powerplant that now pumps out a factory rated 300 hp. In previous models, the 350Z was recorded as delivering 287hp. Along with a revision in horsepower, the 350Z received some updates to the front bumper, headlights, front grille and a spiffy set of LED brake lights.
The trunk capacity within our roadster was laughable at best when measured in size (4.1 cubic feet). We were barely able to shoehorn a cardboard box without smashing it to bits.
The newer '06-'07 350Z VQ35DE engines are referred to as the "REVUP" engines, which produce a rated 300hp and 260lb-ft of torque. While Nissan markets the new and improved "Z" as receiving a gain of 13 more horsepower than its previous "287" (horsepower) models, they fail to mention that torque numbers were significantly affected as the numbers dropped from the previous 274 lb-ft to the present 260 lb-ft; a decrease in 14 lb-ft. of torque. With the aid of MotorDyne and AEM, we were determined to restore those lost numbers while increasing midrange torque and power-an area that's proven to be a valuable commodity both on and off the track.
