View Full Version : Difference between a VQ25DD and QR25DE?
02-28-2002, 03:08 PM
The Spec V has a QR25DE right? That engine putsout 175HP, but another engine VQ25DD is used in the Skyline 250GT and puts out 210HP.
Does anyone know what the differences are between the two engines? 210HP in a Spec V, now that would have been the new definition of "pocket rocket"

If im not mistaken its a rear or awd version of our engine and is considered an Inline 6 not a 4
'97 S14 SE Turbo

All wrong information...
VQ25DD. Same family as the VQ30DE, and VQ35DE in the Maxima/Altima/G35.
It's a 2.5L V-6. There are also the following: VQ20DE, VQ25DE, VQ30DD, VQ30DET, etc.

So you think we could drop the altima engine (260hp) into the spec V? Cause we already have the same 4cyl motor the low end altima has. So shouldn't things match up pretty well? 260hp and lots of torque would be really fun. Just wondering.

Well we have the trans out of the maxima which is a 3.5, images/icons/confused.gif isnt it?

The Skyline 250GT is a inline 6

1st, the Altima VQ35DE is a 6 cyl not 4, therefore it would not fit in our engine bays.
2nd, I have not heard of the VQ25DD, only the VQ25DE, which is indeed a 2.5 v6 with 190hp (I think)
I think it uses more gas, but I still wonder why nissan would design a new engine when they could use the VQ25DE
Also, the VQ is not in the skyline, I believe all skylines have the RB series engines

My bad, it is the VQ25DD with 210hp I was thinking VQ20DE with 170hp

The VQ25DD would be a nice little engine to put on the Sentra, no? Add that with RWD the Sentra would have kicked ass!!!
The new skylines does away with the RB engines and now uses VQ engines.

He was talking about the 250GT, but yeah, new ones have the VQ images/icons/frown.gif
As for rear wheel drive I think it's close to impossible to convert a car from front to rear for a reasonable amount of money, but if your loaded go ahead, I doubt it'd be easy to find the parts that would fit.
As for the VQ25DD, it might not pass emissions.

Umm, assuming you people asking about using VQ25DD engines are here in N America, then dont even think about it. The DD means its a direct injection engine, which require a special type of catylitic converter. However, the high sulfur content present in US gasoline basically destroys the converters, without which you cant hope to pass emissions...
