as bad *** as this sounds. chances are, i aint gonna be able to afford this when it comes out or even 10 years down the line. DOH!

I need ot get a job at the dealership, so I get a nice discount... In 1 year I graduate from school and nissan has already sent me offers....

kudos to nissan for having some balls and releasing a beast. i love the twin variable geometry turbos. that really helps the torque down low. i remember when porche released their 911 turbo with one and it amazed me at the rpm spread of the torque. The gtr will be nasty, and for once i'm glad there isn't an rb powering it.

^ Agreed.

It's really mipressive that they've offset the weight of the turbo-related goodies by making the block and assembly even lighter.

I had originally heard reports of electrically-assisted turbos that would function like a real ALS on a rally car only without the wear, but I suppose that was too trouble prone/expensive to actually implement.

I must confess that I'm not even entirely certain how a regular variable geometry turbo functions.....but I gather it isn't the same thing as having them spin up instantly via electric power.

From Wankerpedia:

Variable geometry turbochargers (VGTs) are a family of turbochargers, usually designed to allow the effective A/R ratio of the turbo to be altered as conditions change. This is done because optimum A/R at low engine speeds is very different from that at high engine speeds. If the A/R ratio is too large, the turbo will fail to create boost at low speeds; if the A/R ratio is too small, the turbo will choke the engine at high speeds, leading to large exhaust manifold pressures, high pumping losses and ultimately lower power output. By altering the geometry of the turbine housing as the engine accelerates, the turbo's A/R ratio can be maintained at its optimum. Because of this, VGTs have a minimal amount of lag, have a low boost threshold and are very efficient at higher engine speeds. In many configurations, VGTs do not even require a wastegate, however this depends on whether the fully open position is sufficiently open to allow boost to be controlled to the desired level at all times. Some VGT implementations have been known to over-boost if a wastegate is not fitted.

The most common implementation is a set of several aerodynamically-shaped vanes in the turbine housing near the turbine inlet. As these vanes move, the area between the tips of them change, thereby leading to a variable A/R ratio. Usually, the vanes are controlled by a membrane actuator identical to the one on a wastegate, although electric servo actuated vanes are becoming more common.

The first production car to use these turbos was the limited-production 1989 Shelby CSX-VNT, equipped with a 2.2L petrol engine. The Shelby CSX-VNT utilised a turbo from Garrett, called the VNT-25 because it used the same compressor and shaft as the more common Garrett T-25. This type of turbine is called a Variable Nozzle Turbine (VNT). Turbocharger manufacturer Aerocharger uses the term 'Variable Area Turbine Nozzle' (VATN) to describe this type of turbine nozzle. Other common terms include Variable Turbine Geometry (VTG), Variable Geometry Turbo (VGT) and Variable Vane Turbine (VVT).

The 2007 Porsche 911 Turbo has a twin turbocharged 3.6-litre flat six, and the turbos used are BorgWarner's Variable Turbine Geometry (VTGs). This is significant because although VGTs have been used on advanced turbo diesel engines for a few years and on the Shelby CSX-VNT, this is the first time the technology has been implemented on a high production petrol car (only 500 Shelby CSX-VNTs were ever produced). Exhaust temperatures in petrol cars are much higher than in diesel cars and this normally has adverse effects on the delicate, movable vanes of the turbo. BorgWarner engineers however have managed to combat this problem with the new 911 Turbo.

Awesome engine specs. I still don't understand why it's being badged as a Nissan though.

i'm a little puzzled by that as well, but in the end i don't really care. the fact that it will be sold here is all that matters i just hope it doesnt hurt sales.

Good job nissan,that made drool all over,i'm suprised they have the balls to do that.But anyways,justin how are ya feeling about your corvette?

MattB wrote: I still don't understand why it's being badged as a Nissan though.

Why not? The corvette isn't marketed as a cadillac.

So Greg... how long til the owner of the internet's largest Nissan/Infinity site has a new GTR? You KNOW you gotta do it man!

Also, do you think they will release any sweet commercials about it? I mean, its not like they have to advertise at all (They will sell them all I'm sure), but then again, how do you keep that sexy beast under wraps?

Holy crap

Does it come with a trailer hitch?

Why would it possibly not be badged Nissan?

Didn't you know? Nissan uses a complex algorithm and actuarial formula to determine engine codes

Soundin pretty ****in awesome! I really cant wait to start seeing this car on the streets!! Since good chances are, I prob wont b able to afford one of my own

wow that is going to be sweet. even tho it will probly be a while before i could even think about the possibility of gettin in one but its good to know nissan isnt flaking on their game. this is the reason why i think nissan owns all other import manufacturers, sure you got some people who come out with 300+ base hp cars but nissan is always on top somehow or another. even if most of us americans havent got to completely enjoy some of their best in the past we definately have a lot to look forward to with what they are offering now. mad props to nissan.

Sounds incredible but hardly rolls off the tongue with that huge mouthful of engine code.

To all those who are going to go out and buy one, take care of it, I'll be looking to get a used one way down the line.

and for those that dont take care of it ill be lookin in junk yards to get your engine!

Does anyone know what the sticker on that badass is gonna be?

I highly doubt you'll ever find a totaled GTR with an intact engine still in it, even if you watch junkyards like a hawk. I highly doubt I'll ever even see one in person except for when I go out to test drive one.

yes that is most likely the truth, but you never kno these days. i seriously doubt i will ever be as lucky either. even if i was ever to find a engine from one which i also see more than likely not to happen for sale i doubt ill be able to afford it. still its a nice thought to have such a fun powerplant under the hood of a 240. especially with that torque band

The VR38 is AWD is it not? That'd be a lot of modifications, and absurdly expensive. I just don't think it's worth it on a 240. Maybe a Z32, but JUST barely. Vette engines seem to be comparable, so it's like, why not just go with that?

for reals.

it'd be easier to package in the engine bay too.

DOHC V6's are quite big....turbos on the sides don't help....

the car sounds sexy.

I hope they do a comparison with the damn RS8.

The motor isn't AWD.

The motor swap, if it fits, probably wouldn't be worth it in a 240 or Z32. Maybe a Fairlady Roadster or 510.

Looking forward to a Top Gear episode about the GT-R.

Don't get butt-hurt Greg.

Nissan's only now catching up to the LS2, LS3, and Ls7.

LS2 = 400hp/400tq, LS3 = 430(more like 450)hp/430tq, Ls7 = 505hp/440tq.

Hey I'm happy for Nissan. It's about time there was some competition for the Corvette from Japan. You're still looking at a year or two, before the GTR even HITS THE ROAD HERE. But the GTR isn't going to be King of the Road in the U.S. Especially since the Blue Devil will be out at the same time with 650hp.

But the Corvette has looked like *** for the last 30 years...

Smelled like it too

Lets hope there are no defects like some of Nissan's other engines. Sounds very promising, and if it is, it would be nice to replace the POS VK45 with it.

running 21 psi, i'm willing to bet that the motor is pretty stout. hopefully it responds well to upgrades.
