I'd go with the 07 base. You get a little more power, if you want you can swap in a quaife LSD later on (plus a 3.9 FD ), and perhaps most importantly the dipstick is in a better location on the 07's

 

Go for a '07 Eth. If you can't find one go for the '07 Base and buy a good LSD for it. IMHO.

I love my Base but, there are times I want the cruise control... not often but, there are sometimes it would be easier on my rt leg.

Good luck ...

 

Saw your threads...

Are you buying a 350Z???

 

is the HR really a huge improvement? i know it has 8 more lb ft & 6 more hp but, thats not huge IMO...is there more midrange than the revup?

 

07 base and throw a nismo LSD in the financing.

We'll it's not so much that the it's a huge improvement. Though some have said that is seems to have better cross the board performance and response to thottle which can mean a lot.

The big deal is:

1) Your getting a year newer car ... Resale will be higher
2) Twin intakes
3) Reworked plenum for better flow - waranteed instead of aftermarket that might cause warantee problem.
4) Hood Bulge - I do not like it.....
5) There was a couple of other minor things I saw but can't remember right now.

 

07 !!!!!

why?

Overview
This is a general overview of the new and/or changed features in the VQ35HR engine.

[edit]Press Release
NISSAN DEVELOPS NEW-GENERATION V6 ENGINES --Engines to power all-new Skyline to be released this autumn--

TOKYO (Aug. 22, 2006)--Nissan Motor Co., Ltd., has newly developed two new-generation six-cylinder V-type engines for front-engine, rear-wheel-drive vehicles featuring powerful performance and improved environmental friendliness.

The 3.5L VQ35HR and 2.5L VQ25HR engines will be built at Nissan's Iwaki Plant in Fukushima Prefecture and will be equipped in the all-new Skyline to be released this autumn in Japan, as well as the US where the model is sold as the Infiniti G35.

Featuring newly designed engine blocks and other key components, the engines offer smooth transition to top-in-class level engine speed of 7,500 revolutions per minute drawing upon the "smooth transition" concept of the popular VQ engine, the only engine in the world to appear on Ward's 10-Best Engines list for 12 consecutive years.

The engines achieve a 10% improvement in fuel efficiency compared to vehicles equipped with the existing VQ engine and top-in-class Super Ultra-Low Emission Vehicle level emissions. SU-LEVs have 75% or less nitrogen oxide (NOx) and hydrocarbon (HC) emissions than those stipulated by Japan's 2005 exhaust emission standards.

The letters "HR" in VQ35HR and VQ25HR stand for "high revolution" and "high response."

Nissan began VQ engine production in 1994 and has produced a cumulative total of 5.5 million units as of last fiscal year, ended March 31, 2006.

Main specifications of the VQ35HR and VQ25HR engines:

Smooth transition to top-in-class level engine speed of 7,500 rpm

Reduction of weight and friction through adoption of asymetrical piston skirt configuration
Reduction of piston-side force through lengthening of con rod
Addition of rudder frame, newly-designed cylinder block with significantly improved rigidity
Thrilling revving sound and top-in-class output

Adoption of perfectly symmetrical intake system
Adoption of continuously variable valve timing control (CVTC) for intake side and electromagnetic valve timing control (e-VTC) for exhaust side
Reduction of intake resistance through adoption of symmetrical twin intake system and straight intake port
Adoption of isometric exhaust manifold and perfectly symmetrical exhaust system
Improvement of fuel-efficiency and emission cleanliness

Reduction of friction through adoption of world's first hydrogen-free, diamond-like carbon (DLC) coating
Adoption of catalyst substrate with ultra-low heat mass, super-ignition iridium spark plug and fast light-off O2 sensor control

[edit]Aim of the next generation VQ35HR engine
The aim of the next generation VQ35HR and VQ25HR series engines has 5 main points. An increased maximum RPM limit of 7500 is realized. Improved sound during acceleration was also one of the key design criterias.

Read below to see the key points of improvement and how they have been achieved on the new VQ35HR and VQ25HR engines.




[edit]High Revolution Rate
Reduced friction and vibration at high speeds
Smoother piston action
Installation of ladder frame on block
Extension of conrod length
By minimizing piston inclination, friction is reduced
Asymmetric piston skirt
Skirt width reduced on side with least amount of pressure resulting in reduced friction.



[edit]Pleasant Acceleration Sound
Linear and clear acceleration sound in response to engine RPM.
Reinforced sound clarity with reduced noise.
Symmetrical Intake and Exhaust system
Aids the production of clear and powerful sounds at high RPm.
Twin intake
Twin exhaust


[edit]Top Level Power Performance in Class
Improvements in intake, exhaust, and combustion
Reduced intake resistance by 18%
Utilize VTC intake and exhaust controls on both sides
Suppresses exhaust loss

If I were you I would...

Never mind. I am not you. Please delete.

 

I would, but I'm not a mod

 

That some funny S#!t !!!

 

 

Just look at that thing it's B E A Utiful !!!

 

2007. The new engine is incredible in so many ways. After that, get a Carbonetics LSD or Quaife LSD.

If your planning on getting an 07 base and adding an LSD..then you might as well step up to the 07 enthusiast and get everything else with it. The price will the exact same...regardless

If you look at invoices, the price difference is less than 2 grand.

I have a base model simply bc it was the only interlagos fire they had, I had an 04 enthusiast before that. The only thing I miss from it is the cruise control. If I were you I'd just spend the extra $1500 for the 07 enthusiast and start having fun.

 

I wouldn't go with a Base, at least go with a Enthu

 

07 foooooooooooooo

 

i got the 07. definitely doesn't pull like my M did. brakes are also pretty weak. ride is a lot rougher, but it's brand new, and i am falling in love with the way it sounds. i and feels. it feels like a true sports car.

i will post pics when it stops raining -_-

oh and, carbon sivler > silverstone

 

^Now I know why people get drunk.^
