It is the same as QR20DE, but new crankshaft with 100.0 mm (3.94 in.) of piston stroke gave the engine a 2.5 L of displacement.
The QR25DE engine has an aluminum cylinder block and head. It used dual overhead camshaft (DOHC), four-valve designs with continuously variable valve timing (CVTC) on the intake camshaft, individual ignition coils, electronic throttle, and multi-point fuel injection system.
The engine built with cast steel connecting rods, a steel timing chain, counter-rotating balance shafts, and an aluminum intake manifold.
An 89.0 mm (3.504 in) cylinder bore and 100.0 mm (3.94 in) piston stroke give the engine a total of 2.5 L of displacement.
Compression ratio rating is ranging from 9.5:1 to 10.5:1 depending on the vehicle.
The Nissan QR25DE produces from 147 PS (108 kW; 145 HP) at 5,600 rpm up to 203 PS (149 kW; 200 HP) at 6,000 rpm of horsepower and from 213 Nm (21.7 kg·m; 157.2 ft·lb) at 4,400 rpm to 245 Nm (25.0 kg·m; 180.8 ft·lb) at 4,000 rpm of torque.
