what is the difference between vq25dd and vq25de
1) which one have neo.
2) how much price difference
3) how to sitinguish ( any photo )
4) power ratio and fc

 

[chteo]

Wikipedia will answer 1, 3, 4.
2 depends on chop shop, and whether engine kosong or whole half cut, but expect 1.8 to 2.5k for engine kosong (with trade-in of your old engine) and 4 to 6k for half-cut

 

[xw4600]

[chteo]

Yup, but so far never heard of anyone putting in a neo into a32, not sure the engine mounting fits or needs modifications or not

I heard that the old VQs (DE i think) gives higher toque specs and hp.

VQDE & VQDD produces the same torque and horses ?? Then, why bother to change to the DD versions?

again from Nissan VQ engine - Wikipedia, the free encyclopedia:

The VQ is a V6 piston engine produced by Nissan with displacements varying from 2.0 L to 4.0 L. It is an aluminum block DOHC 4-valve design with aluminum heads. It is fitted with Nissan's EGI/ECCS sequential multi-point fuel injection (MPFI) system. Later versions feature various implementations of variable valve timing and replace MPFI with direct fuel injection (marketed as NEO-Di). The VQ series engine was honored by Ward's 10 Best Engines list almost every year from the list's inception. The VQ series replaced the VG series of engines.
