The new generation of the vq35 in the new g35.

What do you guys think?

 

Wow.. that's hot. See through valve covers FTW..

 

I think we need about three most posts of this thing in every thread.

 

it will also be offered in a fwd setup in the new altima as well

 

I was reading about this engine the other day.. It's about time Nissan stepped up thier game on the VQ.. The engine has so much potential..

Dual TB? Getting it ready for a TT edition? GT-R engine???

 

It's already done... in the GT-R..

 

still no direct port injection>? ftl

 

in japan they already have vq30's with direct injection...and are experimenting with it in the 35's I believe...but I don't know why they don't bring it over here...they could run way more power by knocking up the compression ratio's and running leaner afr for better gas mileage as well...

also...a while back I saw something about their neo vvl technology being experimented on a vq30 over in japan...that would make some serious power! neo vvl and direct injection on or vq's!!!

 

I think i just wet myself

 

That would be the sh*t... We make some pretty serious power with the SR20VE engines in the Sentra.. I doubt it will see the light of day though.. under the rule of Goshn, or however you spell his name.

VQ30DE 190hp 1995 - 1999 Maxima
VQ30DE-K 222hp 2000 Maxima
VQ30DE-K 227hp 2001 Maxima
VQ35DE 240hp 2001 Pathfinder
VQ35DE 255hp 2002 Maxima
VQ35DE 260hp 2003 G35 Sedan
VQ35DE 287hp 2003 350Z
VQ35DE 300hp 2005 350Z
VQ35DE 300+hp 2007 G35 Coupe

So they've increased the output of the US sold VQ engines on average of once a year, starting from the 1999 model year. And if the 2007 engine produces 310-320hp that would be a difference of 120-130hp in 8 model years from the first VQ we could buy. I would hardly classify that as complacency on their part by saying "it's about time".

However, IMO, anything they do short of introducing NEO VVL and direct injection is a band aid. I am reserving my "it's about time" for when they finally give us both of those technologies.

 

They should have skipped over from 2001, straight to 2007..

 

the 227hp and 255hp figures are pretty dubious.

 

I could have listed them all.

 

Twin throttle bodies!!! ohh that goin to MOVE!! It's about time Nissan freed up their engines to breath.

it looks like 100% DBW no more sole engine swaps w/out ECU upgrades

at least on this engine

pretty cool though

 

wow...that means twice the cost for intakes though...cause you need two of them...however, I agree the NEO VVL, and direct injection is what we should have gotten...too bad only the japanese know the joy of those on the vq so far...I think then the vq35 could put out a ton of power...I wonder what the VQ37 in the upcoming skyline is like...I wonder what they did to the internals, and what it redlines at?

 

To my knowledge there is no VQ in production with NEO VVL. They do have some with direct injection though.

 

I think the reason that Nissan hasn't done direct injection in the US is due to increased NOx emissions.

the gt-r will have a vq35tt.

 

anyone have a link?

very interesting

 

this new gen sounds promisiong. higher compression ratio, dual TB in combination with varible valve timing, shoud make for an even more impressive motor.

I wonder if it will get de-tuned when its to be put into the altima.

"Though touted as Nissan’s range topper, the new Maxima’s last gen. VQ 3.5L V6 only produces 255 hp and 252 ft-lbs. of torque. Both of those ratings are below what the new Altima will be putting out with its “next-gen” VQ."

http://www.autoblog.com/2006/04/12/n...of-the-altima/

"A new generation VQ-Series 3.5L V6 puts out 265 hp and 255 ft-lbs. of torque through either a six-speed manual or through the company’s Xtronic CVT, the latter of which is quite an achievement considering the amount of torque Nissan’s V6 is able to generate."

WOW, this is what really impresses me. That Altima will be the must-have car with it's triple front cup holder.

 

That source is useless if they can't even get the facts straight.

Since 2004 the Maxima ratings have been
265 hp @ 5,800 rpm
255 lb-ft of torque @ 4,400 rpm

They for some reason are claiming this is a new power rating.

It was the 2002-2003 (A33B) that had;
255hp
246tq

 

I've seen more than one source say that the 2007 maxima will only have 255hp due to the CVT.

 

probably it will and it wont have the dual tb IM either.

its hard to say which engine the maxima will have ( new version of the vq35 or the old version of the vq35) but it willl put out 255hp and the only available tranny is a cvt. no manual.

 

I'm sure it'll be the next gen vq35. It wouldn't make much sense to manufacture 2 gens of the same engine at the same time. It'd be more expensive to do that. It will be detuned though and prolly not have dual TB and have a suffocating IM.

 

if that is true about it then, the best option woudl still be the 350z IM but thats another story.

but nissan will probably come out with 2 different IM. One for the FWD vehicles and one for the RWD vehicles. History repeats itself huh

 

no the new gtr will have a vq37tt....I know a nissan master tech who saw the white paper....before he left the company....even road and track said they got this info from an anonymous source...

and a while back on here someone posted a pdf link that was entirely in japanese with a dyno graph of a vq30 with neo vvl...as well as tech info about the technology...it isn't in main stream production on the vq's...but it shows that they have played around with it and tested it...

 

hahahahahahahahahahaha. That's good compton.

 

proof? cause it won't.

 

I agreeeeeeeee

 

vq30dd i think has neo vvl, i had a thread about it a year ago... it cant work here cause it has direct port injection and i couldnt get the rest translated right, but it said something about neo

 

ah...there's the guy who posted that pdf/article...

how do all those german companies and now some other japanese companies have direct injection? do they just lean out the AFR a lot and run really hot to keep emissions down?

 

did some checking around and the new intake system is called "symmetric twin ram air" intake system pretty tech for twin throttle bodies

this new engine has me excited
can't wait to get my hand on that IM!!

 

And that ECU and that wireing....
