Removed Posted July 21, 2006 Share Posted July 21, 2006 news from across the pond... not t a completely new engine, rather heavily revised from the last version, as it is over 85% new. This is the same engine that was announced for the new G35 sedan, and at the time was only said to put out 310 hp (again not a big bump in HP, but rpms have increased by about 1k). NISSAN announced the following specifications: * New design cylinder block. The rudder frame was added, rigidity was raised substantially. * Left and right complete symmetrical inhalation and exhalation air system * Decreasing the friction worldwide first hydrogen free DLC (Diamond Like Carbon) with coating. * Setting electromagnetism VTC on exhaust cam side in addition to the oil pressure VTC of air inlet cam side. * Isometric exhaust manifold Only the '07 G35 and '07 350z will have the new VQ35HR motor. This new engine has increased response and rpms, this allows it to max out at the 7500 rpm redline ("HR" most likely meaning High Rev or Higher Rev) vs 6600 rpm (on 2006 and older 350z) and have improved top end power.

Removed Posted July 23, 2006 Author Share Posted July 23, 2006 depends on point of view though.... diferent compression means BAD news for those people who want to put a FI kit on... so depending on what you want to do with your Z, you might be actively look for a PRE 06 or 07 car Quote Link to comment Share on other sites More sharing options...

Chesterfield Posted August 18, 2006 Share Posted August 18, 2006 so us 05 model owners are now two steps behind. Hmmm - if this is how quickly Nissan make our cars outdated, then I doubt the next one I buy will be a Nissan. Quote Link to comment Share on other sites More sharing options...
Jacko Posted August 18, 2006 Share Posted August 18, 2006 so us 05 model owners are now two steps behind. Hmmm - if this is how quickly Nissan make our cars outdated, then I doubt the next one I buy will be a Nissan. I think to be fair, tis just the normal process of evolution. I don't think Nissan are doing anything that any other sports car maker does..... just trying to keep their product at the top of their relevant tree.....

Chesterfield Posted August 18, 2006 Share Posted August 18, 2006 It was one thing releasing the 06 roadster less thana year after the release of the 05 in the UK, but a new engine less than a year after the 06? That's two updates in less than two years. Most other manufacturers give you at least couple of years before outdating your product with a new model. The 06 owners must be pretty pi$$ed off right about now. Nissan certainly know how to alienate a customer base, and a customer base thathas purchased the flagship model non the less.

Chesterfield Posted August 18, 2006 Share Posted August 18, 2006 Well - in part yes. I have to wonder what Nissan hope to acheive with this. I for one will certainly not buy a New or nearly new model again, whats the point if they are going to outdate and devalue them within a year?

mattuk77 Posted August 18, 2006 Share Posted August 18, 2006 Well, having read this and ordered my Z only three weeks ago I was at first pi$$ed, but thinking about it, cars are like computers, if you wait for "the next version" you'll always be waiting! I'll hopefully be happy at the end of sept and will have 6 months or so before I would have been able to get the new engine... ho hum, price of progress I guess!

rickya Posted August 18, 2006 Share Posted August 18, 2006 If you like buying new cars then I do understand how these things must pi%s you off But I am one of those persons who refuses to buy new & pay a premium & take the depreciation hit, an especially bigger one at times like this. I prefer to buy anywhere from 6 months to 3 years old cars (find a bargain) & change every 3 to 5 years. That way I dont lose much money at all. But obviously its not the same as buying a brand new car & the feeling you get of being the first owner. But I do find it a bit stupid of Nissan to do a facelift in 06 & then do an engine change in 07?? Quote Link to comment Share on other sites More sharing options...
Guest prescience Posted August 18, 2006 Share Posted August 18, 2006 I know what you mean but as you also note there is nothing like owning a car from new and knowing that nobody else has thrashed it or whatever. Buying cars is never (well unless you are super-rich) an investment and should never be worried about on that score, buying property is Quote Link to comment Share on other sites More sharing options...
H5 Posted August 19, 2006 Share Posted August 19, 2006 Who know what this new engine is like too. It may be unreliable, thirsty, not nice to drive and everyone favours our 'out of date' cars. I don't see it as anything to worry about. People still buy Escort Cosworths of all ages and specs - because they're awesome cars. People will still spend £20k + on one rather than an Evo...... Same will happen with the Zed IMO. The range is good, if they develop it then I think that's good for keeping the name going and the second hand market good for us. Plus, you're driving it now, not next year!! Quote Link to comment Share on other sites More sharing options...
Removed Posted August 23, 2006 Author Share Posted August 23, 2006 some more info: "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" play sound: http://www3.stream.co.jp/web06/nissan/p ... kyline.asx d/l sound: http://www3.stream.co.jp/web06/nissan/p ... ne/wav.exe sources = http://press.nissan-global.com/EN/PHOTO ... ology.html Quote Link to comment Share on other sites More sharing options...

Traktion Posted September 20, 2006 Share Posted September 20, 2006 I guess it depends whether they just switch the whole VQ production to the latest model or not. Unless there is a lot of costly materials used, I should imagine they'd just use the new design in all the cars where it would fit. I don't know much about engine production, but I'm guessing that once you've re-tooled, it's easier and better to use the new design everywhere feasible?

GC350z Posted September 20, 2006 Share Posted September 20, 2006 This is certainly an interesting topic. The new Skyline / G35 has been available since 2003 using the same lump as the Z. The major difference as far as I can remember is in the saloon version of the Skyline (350GT-8). There's a 8 speed auto box available. That's not a typo. I suspect the real change though is because the GTR is due out next year and as yet the engine has been kept a secret. It's rumoured to be a twin turbo 3.5 pushing out 400 - 500 bhp. So because Nissan share all the parts between their models to reduce costs the engine is being altered to accommodate the GTR. Could be very wrong here.
