well the QR25DE also has some sort of variable valve timing. it has a motor in the intake cam sprocket that adjust the timing for more torque or top end depending aplication. but the only reason why i see the civic as costing more is becsaue the SE-R is made up from the parts bin of other cars. the sentra chassis, the altima 2.5 liter engine, and the maxima SE's 5 speed gear box.
