In late July, Nissan confirmed its new VQ35HR engine — which will appear in the 2007 G35 sedan — had achieved an SAE certified rating of 306 horsepower. Today, the automaker released a few more details:

* 10% improvement in fuel efficiency
* Super Ultra-Low Emission rating
* Smooth transition to 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
* 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
* 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

[Mr.Duck]

:drool: 7,500 rpm redline.......... mmmm

an SAE rating of 306 hp? damn.. nissan is doing something right for once huh?

[Nissan 6]

Just when you thought it couldnt get any better....

[Kowalski]

now let's just hope they don't catch fire...

[Ovaltine Jenkins]

wow, maxima.org thread from 2 months ago...

[Mr.Duck]

well i never saw it... and i'm sure a few other people havnt seen it yet either...

[Mr Grey]

I was waiting for Dave to say that. :wall:
I saw it, but many here don't vist the org.

[Xmax]

I haven't seen it either, but I knew that the 2nd gen G35 was going to have at least 300hp. Hmmm a few years from now, I wonder how much those engines will be going for.

[Ovaltine Jenkins]

yay, an 8hp jump from 298 to 306. I'm also guessing a big TQ drop is in order since the 306hp is most likely close to redline, the tq would be acura like...

[walec05]

oh nice, i wonder if we have any info on this. hhmmm.

[THT]

Wish I could find one in a salvage yard...

[walec05]

ya, that would be nice. but maybey you will find one in 2008.

[DasTeknoViking]

Blehh another lowly 3.5L VQ..... Honda is working on a repleacement engine series for their aging J-Series V6s. The current 3.5L VTEC SOHC makes almost 300HP. Honda is working on a 3.5L DOHC with I-VTEC, it should provide class leading power you would expect from a Honda engine. I was told that 100HP per liter will be standard, and it will spawn a RWD sedan or 2 for Acura.

3.5Ls are garbage engines. I don't see nearly 10% of problems with our J series engines in Acuras that Nissan dealer next door sees with the 3.5s.

My last Nissan so it doesn't matter.

[walec05]

same here, this is my last nissan. there are too many problems with the new cars, and if you have a older car, its almost the same problem.

[DasTeknoViking]

With the way automotive industry is "evolving" every car company out there is going to be in some deep shit in the near future with their bland unreliable products.

I dont see any problems with the engine in my car being a 3.5L.
Why would the vq be rated one of the best engines out there if they are junk?? And for the last 10-12 years straight.
I have had nothing but luck with nissan since the first maxima we had in 1988. That was actually probably my favorite car out of all of them.
I will never buy a honda, dont care how great they are.
And Paul, you are talking about the QR motor, those have always been shit....and they are only getting worse. Thats why I got rid of mine.
But how many 3.5's do you see come in with any major engine problems?? And what are they?
Other than that piece of shit minivan that nissan makes....where EVERYTHING falls apart.

[DasTeknoViking]

Alot of people with higher mileage 3.5Ls have oil burning problems. The 4.5L VK45DE in the M45, FX45 and Q45 has oil burning problems also. I am NOT used to checking my oil level, and I refuse to put EXTRA oil in the engine. If it burns oil, it means its no good. My 160K mile VQ doesn't burn it, neighter my SR or VG did. My 00 Altima with the venerable KA24DE doesn't burn a drop of oil

[Just_A_Wrx]

Well, knock on wood, I hope that doesnt happen to me. So far it has been great. Our 88 maxima was the best. It went 140,000 HARD miles. My father didnt even change the oil for at least 6000 mile intervals and NOTHING went wrong with that car. What motor was in that car??
But it will take me a long time to get high mileage on this car, and by that time I probably wont own it anymore.

VG30E
10char

[DasTeknoViking]

Most people notice increased oil consumption at around 50+K miles. GBAUER on the .org actually had the most miles for a 3.5L anywhere- like 150K when his engine just went out due to oil problems. His car would burn oil more and more gradually. Its not a uncommon problem for the 3.5L, if you look around on the Z, G, FX, etc.... forums you will see that this isn't just a "maxima" problem.... this problem has been around for a while. VQ30 doesn't have any of those mechanical problems.

VG30E is a excelent engine, so good that Nissan made it for 20+ years and it came with twin turbos, high HP NA, Supercharger, single turbo option and few diff displacements. It was probably THE best V6 ever made. Simple and reliable. VQ30 is slowly getting to the VG status of reliability, 3.5L unfortunatelly has way too many problems to be considered a great engine. Sure enough its got power, but I also look at reliability.

If you don't drive alot, you probably won't see the oil burning problem happen.

VG30E

The 3.0 L (2960 cc) VG30E produced 153 hp and 182 ft.lbf. Bore is 3.43 in (87 mm) and stroke is 3.27 in (83 mm). In 300ZX form, it produced 160hp and 174lb-ft. 1988 saw the 300ZX gain 5 more horses for a total of 165, however torque ratings remained the same. In 1989, the Maxima received the 160hp rating, but also used a variable intake plenum that let it make 182lb-ft@3200rpm. Strangely, the 300ZX never received the variable intake plenum.

It was used in the following vehicles:

* 1984–1989 Nissan 300ZX/Nissan Fairlady Z
* 1987–1988 Nissan 200SX SE
* 1984–1994 Nissan Maxima
* 1990–1991 Infiniti M30/Nissan Leopard
* 1990–1996 Nissan pickup
* 1990–1995 Nissan Pathfinder/Nissan Terrano
* 1992–1999 Nissan Gloria/Nissan Cedric
* 1992–1995 Nissan Quest/Mercury Villager (modified to become a non-interference design)

VG30ET

The 3.0 L (2960 cc) VG30ET was available in early production with a single Garrett T3 turbocharger and a 7.8:1 compression ratio. The USDM version produced 200 hp and 227 ft.lbf. In 1988 it changed to a single Garrett T25 turbocharger and an 8.3:1 compression ratio to reduce turbo lag, and was bumped to 205 hp and 227 ft.lbf. No VG30ET was ever factory equipped with an intercooler as they featured low boost pressure for fast response.

It was used in the following vehicles:

* 1984–1989 Nissan 300ZX Turbo
* 1984–1986 Nissan Fairlady Z
* Nissan Leopard
* Nissan Gloria/Nissan Cedric
VG30DE is a seperate motor

[DasTeknoViking]

One can argue that the VQ35DE is a separate motor from the VQ30DE, and that the VQ40DE is also different from the other 2.

When I say VG motor- I mean every motor within the whole range of VG motors, same wouls apply to L-series that came in 6 and 4 cylinder applications.

[Brian]

I wasn't arguing, just pointing out that people commonly group the DE with the E, but they only share a Block and that's it.

[DasTeknoViking]

They dont even share that.... you CAN'T put the DOHC heads on a SOHC block. Not possible. Displacement and its bore dimensions are same, but the blocks are indeed different. I wanted to build a 95 Pathfinder once, put DOHC heads on it and the block was different.

[TurTLe]

the newer engines haven't had any detailed research done to it. They are just out to make the numbers. VW has been fighting off the number of engine replacements on the 2.0L engines due to oil consumptions and the 1.8T in the passat with had a bad oil pump and tentioner. The 1.8T passat is the same engine running on the 1.8T A4. But i dont think the A4 shares the same problems.

I've seen next door there are countless 3.5L issues. On top of that everyone that owns a 2.5L thinks its going to catch on fire now. Something is up with the Z's everytime i walk in the shop every Z has the rear cradle out and the exhaust hanging.

I don't see myself getting anything newer then a DE-K. But i am trying to go SR20DE way.

[DasTeknoViking]

96-98 A4 1.8Ts had oil pump problems also...... I've done a few of them under warranty yeaaaars ago.

My brother owned a 00 Jetta 2.0L, it burned as much gas as it did oil. When he wanted to get it fixed, VW said "its a high compression high performance engine, it is supposed to burn oil"...... well how can 115HP 2.0L SOHC motor be called HIGH PERFORMANCE ? Stupid VW. He bought a 4th gen and put like 100K miles on it with ZERO problems.

[TurTLe]

Mike, those 2.0L are infamous for oil consumptions. We all know its there but we really don't like to give out free engines because for warranty costs for oil consumption 2.0L pay out like 4 some odd hours. Theres a crap load of paperwork that needs to be filled and they need to come back to the dealership every 500 miles for like 6 times to do all this stuff. Its really gay.

lol high compression peice of crap. That motor has no balls what so ever. They are carry so many issues. More the reason for me to get out of the VW world.

I was driving my 00 Altima GXE AUTO today driving the woman home, some fully riced out Beetle 2.0 5spd with a big GTR wing, body kit, huge tach, gauges, graphics, exhaust etc.... tries to race me. I didnt know if it was a 1.8 or a 2.0 so I didnt even wanna go... but 2nd light he takes off hard, chirping 2nd gear and going all the way to like 60 and then slowing down to 50.... I was next to him the whole time- AND my Altima shifted at like 3800RPM each gear as I wasn't even racing him. Next light I brake torqued the Altima and manually shifted- I ended up pulling good 4 cars on him to like 70 where I shut down.

Altima mods- 15" 99 G20 wheels, K&N drop in filter, Timing advance, 02 RSX Type S exhaust tip.

VW makes Garbage cars.

nice altima mike, u know what it is.......that rsx exhaust tip.

2.0 power!!! haha i get girls with the same car like that but in auto. Aleast some get the 1.8T and are chipped tho. But yea they make shit box cars. My 4th gen auto kept up with a vr6 5spd untill he was in 4th and started to pull on me.

Our new 3.6L 4-motions Passats are decent, supposely its going to be on a "R36" sometime soon.
