2014 Nissan GT-R Engines Get Enhanced

BY Joel Tam

As if it needs more power and 'improved throttle and acceleration feel' - the Nissan GT-R still gets it anyway. That, and an aluminum nameplate with the name of the engine constructor.

Based on the already improved engine with better intake efficiency, reduced airflow resistance and improved exhaust emissions efficiency, the current powerplant in the GT-R has been upped by 15 bhp to 545 hp, and 20 Nm of torque to 628 Nm.

You think that should do it, but no. Nissan's engineers have fitted new fuel injectors to enhance torque response in the 4,500 - 6,000 rpm range. They claim that will be 'improving throttle and acceleration feel at mid- and high-rpm ranges'. Really? We'd be able to tell the difference?

Other bits include an oil pan baffle that has been added to stabilize oil behavior and oil pressure under high performance driving conditions. The baffle reduces rotational friction, which contributes to the increased responsiveness.

Since each Gt-R engine is hand-assembled from beginning to end in a special clean room by a single specially trained technician, for 2014, an aluminum nameplate will be added to each engine showing the name of the engine constructor. That's quite cool.

Other tweaks on the new refreshed car include forged aluminum 20-inch wheels, manufactured by RAYS®, utilize knurling inside the wheels that help keep the tires from slipping around the wheels under heavy acceleration or braking. The Black Edition features special metallic black six-spoke RAYS® forged lightweight wheels in place of the Premium model's 10-spoke design.
