Default How does the D21, and D22 compare?

I am wondering about the 4 cylinder in the D40. Is it the same engine they put into the D22?

This is from wikipedia. I wonder why the Altima get 175hp, and the Frontier gets 154hp.

QR25DE

The QR25DE is a 2.5 L (2488 cc) variant built in Decherd, TN with cast steel connecting rods, a steel timing chain, counter-rotating balance shafts, and an aluminum intake manifold. The engine bore is 89 mm with a stroke of 100 mm and a compression ratio ranging from 9.5:1 to 10.5:1 depending on the vehicle.[1]
Output is rated 175 hp (130 kW) at 6000 rpm with 180 lbft (244 Nm) of torque at 4000 rpm in the Altima 2.5 and Sentra SE-R models. Altimas that are PZEV compliant create 170 hp (130 kW) and 175 lbft (237 Nm) of torque.[3] In the 2005+ Nissan Frontier the QR25DE generates 154 hp (115 kW) and 173 lbft (235 Nm) of torque.[4]
