Yea tonight i went to a local car meet around where i live and this dude pulls up with a 300zx.. we started talking.. led up to engines.... anyway he was like the new VQ motors are garbage and the internals are crap he was like the VG30 (which ever motor is in the 300zx) is way better and can handle lots of power compared to the VQ motors can anybody tell me how to prove him wrong ????or can't I

 

theyre both great motors, for some reason nissan replaced the vg with the vq, i know the vq is supposed to be a lot lighter. the z line went from vg to vq just like the max did.

 

same engine different displacement.. that's it......

 

I bet i can show him up of i had a motor like sr20den his car is NICE.....its all ready nice running 12.8 but if he broke 12 i would shutup and drive a KIA........... no i wouldnt

 

does he has a TT or normally aspirated one. You can easily race a non TT, but a TT is a different story

 

no his is normally aspirated from what i belive its crazy

 

Are you effing serious?

 

That's what Iam saying lol

 

The stock internals on the old 300zx could handle alot more boost/horses than the new VQ ever could because they were built to withstand boost AKA " TwinTurbo" models. Your buddy is right your wrong.

 

soo VQ's suc and vg are better but i herd vg have lots of problems

 

No the VQ does not suck. But if you are serious about boosting you could definetly pick a better engine then the VQ 3.5. You would be better off with the 3.0 VQ.

 

Sorry to hijack your thread BUT I have a feeling that 2006 will be the year that the VQ is kicked out of Ward's 10 best engines. Lexus' IS 350 which uses direct injection bests the VQ 3.5 used in the Z/G35 in both power and torque & yet offers better fuel economy.

 

well i hope when the new skyline debutes it has a well built motor.....like 2jzgte,rb26dett,sr20det amazing motors

 

The VQ was never the most powerful or fuel effecient engine, but still won. I'm not daying it will win again, I'm just saying your points hold no water because of my 1st statement.

 

It HAS been the most powerful & torquey naturally aspirated V6 for the 11 years it has won. Its brake specific fuel consumption has also been among the best. Is refinement enough to carry it through? I don't know.

 

Even in 99 when Accord had 200 hp from their J series, and Maxima had 190... Pissing contest I know, but

 

i know the vq35 is a great engine i love driving my max.... i just wish the internals were beefed up with all the HP that it puts out..then i think it will be on the list for another 10 yrs

 

You are right. I swallow my words

 

what's the point of this? It doesn't have to have beefed up internals to win wards 10 best

 

theres no reason to "beef up" the internals cuz there is no need for it. like was said before, the 300ZX has a TT version, so its block had to handle that power. there is no TT version (stock) for the VQ35, there are just several different versions of the same damn engine. like i said in the other thread about the maxima being "dead" in its 7th generation, Nissan isnt designing these engines with the thought that SSR and whoever else is going to turbo them, they design them to win sell cars, and win awards, which will sell cars.

 

Theres no reason to compare the older VG series of engines that nissan started back in the 80's to the newer higher technology VQ's that we have today. For there time the VG's were very robust and could handle great amounts of forced induction. There iron blocks could take years of abuse and mileage into the 500k mile range.

But comparing the VG's old belt driven sohc cams(on max's), distributor style ignition will show they are a far cry from the all alum, chain driven dohc, with coil on plug, VQ's we have today. Not to mention the advances in alloys, friction reduction and lower NVH that has made the VQ so dependable, powerful and resistant to failure even under hp outputs sometimes tripling there original amounts with stock internals.

Lets just wait and see how a new VQ stacks up when a TT version comes out under the hood of the Infiniti Skyline in 2007 boasting 500+hp stock.

 

I totally agree. The new VQ is a technical marvel compared to the VG. In my opinion there's nothing wrong with the new VQ. Maybe it could be a little smoother but the motor rocks and has tons of low end tq....

 

ha ha , I have both engines

 

I thought the only real "weak" point in the VQ35 was the rod bolts. Change those and you're ready to start boosting. Correct me if I'm wrong here...

 

Rod bolts are weakER than the VQ30, and the 3.5 has a longer stroke so there's more mechanical stress even at lower rpms vs the VQ30.

The rod bolts are a different design when comparing the 2 engines. And well, they are changed out typically for higher rev apps and w/boost, might not need as much revs.

 

That's also assuming the new Toyota 2GR-FSE raises the bar so high that it would put the VQ35DE to shame......to wit, I doubt that's happened.

IMHO, Toyota's intro of this motor will probably result in Nissan further enhancing the current VQ (i.e.: adding DGI, VVL, etc,...).


Ward's

 

The ignorance in this thread is outstanding.

Do some research people.

 

Pls explain...

 

ignorance on what ??

 

I think that's what threads like this are for...

 

I know, there is just alot to cover and now I have time to start.

 

The NA versions of the VQ aren't build to withstand loads of FI power like the RB. They have FI versions of the VQ30 in Japan which are built that way. But the VQ does make more NA power and uses less fuel than any VG has ever been capable of. Nissan wouldn't take a huge step backward in technology, which is what that guy is trying to imply. However it is entirely the opposite.

The VQ block, even having a wet deck, is stronger than the RB26 block and the 2JZ block. There are already a couple VQ engines making over 1500whp which proves their capability. You won't however find any VG engines that can get close to that.

 

The guy is only right about comparing the VG30DETT to the VQ30DE or VQ35DE as far as FI power capabilites are concerned. However it only takes a few internal changes to make the VQ easily outshine the VG in that department, and it will do so more efficiently.

The guy is 100% wrong with the 'crap' comment. And if you look at every angle and fully compare them it is easy to see that the VQ is far superior to the VG in almost every aspect. It also hasn't really been proven how far the stock VQ35 rods can go. People tend to forget the high 10.3:1 comrpession ratio of the VQ35, as comapred the the lower ratios of the VG30DETT. This alone makes it very difficult to compare them for rod strength.

 

I suppose this could be based on a personal preference, but if you observe everything that has been done on both engines you'll notice that the stock VQ35 long block has been pushed further than the stock VQ30 longblock when comparing FI alone. Sure Hal made 522whp on a stock VQ30 but he did so with a big shot of nitrous on top of the FI. There are plenty of stock VQ35 engines running around with more FI only power than he made. And they aren't needing to replace their engines all the time like Hal did.

But is this even a fair comaprison? Certainly not. Therefore this issue hasn't been proven by anyone because there isn't any reliable data to claim which one is really better for this purpose. If you decide to compare the aftermarket availibility of parts then you can easily see that the VQ35 wins hands down.

And even from a personal preference standpoint, I would want to take the larger displacement engine knowing they're indentically sized on the outside. As well as the larger intake valves, more aggressive cams and better flowing heads.

But to each his own.

 

Nissan has already been using DI in some VQs in Japan for a few years now. The VQ30DD makes 256hp @ 6400rpm. Just imagine what a VQ35DD with dual VTC will make. Or even better yet, if/when they decide to add their NeoVVL and release a VQ35VD beast onto the market. A config like that could easily make 350-400hp in street form.

Nissan has been improving the thing every two years or so since 2000.

Even if they don't release that technology to the US market I still doubt the VQ35 will lose it's spot on the Wards list. The last enhancements (300hp Dual VTC) they made has already bought it another few years on the list.

 

All Hail king SR20DEN

 

agreed. I hope they bring the VQ30DD over here...

 

you see this guy around a lot?

sounds like hes jealous about his inferior, outdated engine.

i have both engines, the VG, although an (E), doesnt even hold a candle to the VQ35.


next time you see him, ask him if he wants to race a family car with a crap engine. i'll gladly make the drive.

 

The thread starter stated that a guy he met said the "STOCK" motor in his 300ZX could handle way more power than the 3.5 thats in todays Maxima. My answer was he is correct. There was no mention of a few changes to the stock internals to the VQ in his post....... Stock engines which could handle more power? Thats the answer I gave him.

 

He never specified if it had to be stock. But to me it sounded as if the guy was grossly exaggerating and passing off his opinion as fact.
