Does the 2003 Sedan 6MT have the VQ35 or the VQ35DE engine? All coupes, auto or manual seem to have the DE.

 

From what I have read, the D stands for DOHC and the E stands for Multiport Fuel Injection. The Sedan has both of these features, correct? Infinitihelp.com says the sedan is a VQ35 and the coupe is a VQ35DE, that's why I ask.

G35 coupe, G35 sedan, M35, i35, fx35, murano, xterra, pathfinder, quest, 350z, altima 3.5, maxima, all have the VQ35de with minor variations in intake/exhaust systems and cams. timing/tuning is the only real difference between the various cars.

the frontier has a bored out vq with 4.0 liters of displacement

This vq35de is a modified version of the vq30de found in earlier maximas/i35.

it is not the same as the vg30de found in earlier 300zx's.

other engines in nissan's stable are qr25de (sentra/altima), vk45de (m45, fx45, q45), ca18de (sentra), sr20de (sentra), and the 5.6 liter in the titan/armada/qx56

 

In body style, V35 designates the Sedan and CPV35 designates the Coupe. Same engine used in both as 3point has already stated.
