[xw4600]

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]

so.... should go 4 vq25dd .many converted 3.0 to 2.5 in carlist is without neo lor.

 

[chteo]

Vq25dd not as common as vq25de ma...

 

[xw4600]

if can get below rm24k with neo supplied ....wow wow wow

 

[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

 

[sb3]

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

from Wikipedia:

VQ25DE

It produces 190 PS (140 kW; 190 hp) to 210 PS (150 kW; 210 hp) @6400 rpm and 174 to 195 lb·ft (236 to 264 N·m) of torque. Later versions produce 186 PS (137 kW; 183 hp) @6000 rpm and 171 lb·ft (232 N·m) @3200 rpm. (1994–1998 Nissan Cefiro A32)

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.

ummph yes, but the LSD i think mainly with the rear wheel drive such as the Stagea and 4 wheel drive only...

[imperialrealcs]

My de also has LSD...

 

[weikee]

Highest as possible. 97

 

[imperialrealcs]

alamak, 97 is just too expensive la. any documentation from nissan ar?

 

[weikee]

When Malaysia introduce Ron-95, motortrader and other auto magazine already publish what car can use. Cefiro A32 and A33 is advice able to use 97. Go search the old news. And Japan mostly use high octane fuels.

You can try 95 for few tank, you know the difference. Even my wife can tell the difference. Alternative, fuel 1/2 95, and 1/2 97. The difference will not be that bad.

 

[imperialrealcs]

yes, i saw that news. but it state there ron95 compatible but ron97 recommended. maybe is the power issue that the engine have to retard to accomodate ron95. maybe i should emanage it to take ron95
