Oh! They finally put that 7 speed auto in the G? Cool. I know that as far as manuals go, though, they didn't put the syncro-rev match trans in the G. They're saving that for the Z.
Yeah, I've heard really good things about that Auto. The torque converter is a 5 disc variable lockup from 5% to 100%... Should be as a good as a clutch, just a bit heavier.

370z stock has run 13.2@107mph in one of the magz there no joke. and really to bash nissan is kinda stupid. there engines are good quality and last a while. and there trans are no slouches either. this is just in response to the guy on the first page resorting to "well its nissan" as an excuse that is less of a car.. pretty good ricer mentality there.
I don't know how you can say Nissan makes good motors when they still produce piles of crap like the 2.5L, which are notorious for eating piston rings and needing entire overhauls before 75,000 miles due to excessive oil consumption.

Nissan motors are nothing to brag about. Read any review about the 350Z or 370Z or G35/37 and you'll read complaints about vibration and harshness. Its an unbalanced motor, and you feel it in the cabin, shifter, and pedals in the higher RPM's. The higher you rev it, the more unrefined it gets. Not only that, but it also has a relatively horrible intake/exhaust sound, which reviews often also comment on. The VQ also has oil burning issues, not sure if they've corrected any of those with the newer versions.

I've driven a few 370zs. I also had a G35. I never once thought the sound was horrible. In fact, I like the sound. At high RPM, I didn't feel any harshness in the car at all. And I didn't hear any rattling either. But I do hear rattling in a lot of GMs. My dad's 2007 Solstice GXP rattles like crazy already. My Z06 doesn't, though.
As for burning oil, from what I understand, just using Mobile 1 in an LS1 will burn oil. I don't know if you can say that the 370z burns oil just yet. The oil doesn't even get hot enough to burn because if it goes over 240*, the engine goes into a degraded limp mode and waits for the oil to cool down. I do know that the Zs are having oil cooling issues on the track, but that's being solved by aftermarket oil coolers.
My Z06 is harsh at higher RPMs. It's quite smooth at lower RPMs.
So IMO, your statement is pot calling the kettle black.

um what?? 60 degree V6 engines like Nissans VQ series are the most balanced engines you can have aside from an inline 6 or a V12. We have 5 different Nissan V6s in our garage/driveway both modified and stock and I can assure you there is no harshness in these engines. In fact i'd venture to say Nissan builds some of the best V6s in the world and has for some time.

Most manufacturers correct it with balance shafts (like the 3800 Series II), Nissan doesn't.
There are only 2 naturally balanced engine configurations that exist. The straight 6 and the V12. The V8 is balanced due to its crossplace crankshaft and counterweights.
Read any review of the 370Z and you'll see the same thing.
Per Motortrend:
"Naturally, there are a few characteristics of the new Z with which we're not entirely enamored. The VQ engine, while more powerful and polished than its predecessor, still exhibits a coarseness near redline. Further, that coarseness rears its unwelcome head in the gearbox and pedals, transmitting a slight vibration to your hands and feet when firing off high-rpm shifts."

GMs 3800 V6 on the other hand is a 90 degree V6, 90 degree V6s are produced so they can use the same production-line tooling set up to produce V8 engines (which normally have a 90-degree V angle). Although it is relatively easy to derive a 90-degree V6 from an existing V8 design by simply cutting two cylinders off the engine, this tends to make it wider and more vibration-prone than a 60-degree V6. 90 Degree V6 engines need balance shafts and large counter weights to operate acceptably smooth.

Except if you take the 350/370 to redline the gear shift lever will vibrate pretty well from what I've read. Incorrect?

Drive one and you tell me, i've never noticed it. The only vibrations I can think of that they may be referring to is the new VVEL(valve timing system) thats in Nissans new 3.7Ls and 5.0Ls, its similar to BMWs double VANOS.

Except they don't share the same platform. They're a completely different car sharing the same motor and in the Auto form, share the same transmission... That's it. Even the frame is different. The G37 has a longer frame. And it's not as stiff as the 370z's frame.
I don't know how many of these cars you've driven, but I didn't notice any vibrations in my hands or feet while driving the **** out of them. And I wear thin-soled pumas while I'm driving.
I think personal experience always talks more than an "editor's" opinion.

Lots of uneducated people in here.

you're preaching to the wrong crowd here. the shifter itself could be a vibrator and they still would say that they didnt notice any vibration, even though it a commonly accepted problem with the nissan rice burners.

Stillen Gen 3 Long Tube Intakes on the 370z dyno'd 15RWHP more alone. I couldn't believe the numbers myself, but I started seeing independent dynos on different machines (dyno jets, mustangs, etc) and they were all coming up with huge gains.
Berk test pipes, Stillen Gen 3 intakes, and pretty much any cat back exhaust was yielding serious numbers to the ground. With just those 3 items they're making over 300 to the ground. Apparently, there was a lot to gain from simple bolt-ons. There's also headers out, but I don't believe they made that much of a difference (maybe 10RWHP). Either way, F-bodies are going to need to step up their game and get LTs, CIA and a dyno tune to stay in front of the new Zs.
I haven't raced a new Z yet in my Z06, but I'm anxious to. Had an opportunity last week, but I didn't really know the car yet, so I didn't do it.

90 degree V8s are not inherently balanced but like a 60 degree V6 they are considered a balanced engine. 90 degrees is optimal for V8 engines and 60 degrees is optimal for v6 engines.
Don't need to, i've driven 370Zs and Nissans new 3.7L is one of the best V6 engines on the market. I also have 5 different Nissan V6s here in my garage/driveway ranging from 230HP-450HP and they are all very smooth well built engines.
