New GTR: VQ33DETT

[adey]

The GTR followers may already know this, but apparently the new generation of GTRs will be powered by a twin turbocharged 3.3 litre V6 ... or at least that's what I can make out of this magazine I'm reading.
Earlier speculation spoke of Supercharged V6, but it seems like they even have a working prototype for this VQ33DETT. 400ps at 7200rpm and 50kgm at 4500rpm. 1,500kg curb weight with 275/40/19 stock alloys stopped by 4 piston brembos up front. 93.0*81.4 bore*stroke.

...This article says something about a power (electrically) assisted Turbo... maybe they're thinking it will be twin-charged? ... interesting.

Anyway I just thought I'd bring out some (new?) news. :)
Speculate away!

I know what they did! The prototype consist of a standard t3 setup. But for the extra kick in the pants, they went out on ebay and got that eletrical turbocharger.... I knew these were for real, Im going to buy fourty right now and sell em in two months when they get hot!!

:rolleyes: :rolleyes:
:D

well adey , its getting the setup I have been saying it would have.
People have been specutating on the twin turbo V6 setup for months . You just confirmed it. What I really like is the horsepower figures . It also proves that the 350z is being considered a entry level sports car. Which puts another nail in the coffin of any more Silvia's. Even if they did use a new chassis platform.

vk45de + supercharger > vq33dett :mad:

[Ryan of Velocity]

I hope you are relying on the "gossip" magazines. I've seen alot of people talk about this and all their information is coming from magazines of that type.

But I would agree that that is most likely going to be the setup. Look at the GTRs in the JGTC running twin turbo VQs:) Makes you think.

[nrcooled]

You beat me to it. They have been prototyping the tt setup in JGTC so it will be interesting the exact setup. Has anyone seen the engine bay up close on the 350? I can't imagine that they would TT the 350z due to the lack of space in the engine bay. ::NO room for intercoolers or plumbing:: Even in the wheelwells there is no room due to the sophisticated suspension setup.

Just my .02 Although I would love to see it

I read here often but here's my first post.

wow, now that is a beautiful sight :). I really wonder though, how in the hell did they fit that in there?!?!

[Ryan of Velocity]

That's the Power Enterprise twin turbo kit. It's hasn't been released yet as they are finishing up the final touches. You should see the shots from the bottom, it's a tight fit but it works. Nice bolt on 100HP on conservative boost:)

Our next project is a Z33 and we're throwing the entire PE Z33 parts lineup on it:)

Probably going to have no knuckles left after strapping the turbos on..lol.

[nrcooled]

It looks a tad bit photochoped but if that is the real deal then kudos to the characters who came up w/ the setup.

[misnomer]

Beefy looking setup, but I'd hate to have to work on an engine bay that cramped. . .

[ridebmx]

that is one thing that sucks about newer cars, christ the hold ones you could just hop under and the hood and have alll the room in the world, you could pretty much stand in there, or atleast sit comfortabley and still be albe to get at every bolt....and then not having to worry about sensors, sensors and then more sensors

[transient]

Sensors are fine with me, it's the endless mass of vacuum tubes that I hate :p

[Silviaholic]

I wonder how you change the headlights....

:-)

[DarkRaptor42]

my 350 is cramped but if you take off the cover there is alot more room than it looks like there is. I got this little bit of info from a nissan mechanic who told me the reason why they did it like this is to discourage people from changing the oil and what not in the car themselves but to instead take it to a dealer. Its the same block in all the new nissans so go figure. As far as a TT though, the car already hauls ass, I cant even begin to imagine the power of the TT. But as I was told at a dealer last night, the TT has been pushed back a year due to the outstanding sales of the 350. The convertible is also pushed back a year.

All this VK and JTGC (sp?) talk is confusing me a bit, albeit I sound like a brand spankin baby noob, can someone please enlighten me to what this are?

JGTC Japanesse Grand Touring Championship I think that is what it stands for???????

On and if people are wondering about the power assisted turbo charger, it was first used on SAAB's about ten years ago! They used an electric motor to spin the turbine while the engine was at low RPM levels. If i remember correctly they never perfected the system, so they stopped using it!

I think they should have used the VQ35DES :D I think a supercharger would have been better for the GTR than twin turbos (probobly going to get flammed for this)

"Talk amongst yourselves,"

[Silviaholic]

Thank you for clearing that up for me... I dont see why you should be flamed... people were prasing the idea of a SCed 240 a little while ago

[DamnedButDetermined]

I think a turbocharger is better suitted for a 240sx, because in order to make 400hp on a KA24DE you will have to have a turbo (I thin)...But a supercharger is more suited for a Skyline, b/c it can easily create that much horsepower on a supercharger, and it will be available alot earlier than with a supercharger!

I agree.

Some mag said the USDM is going to have the VK45DE, now all it needs is a NISMO supercharger kit = VK45DER
(if i remember correctly nissan use R instead to S to denote a supercharger. like in the Xtera S/C VG33ER

Let the USDM conversion begin! :D :o

Boost is boost. Sc or T. Parisitic engine drag would be the only factor.

A supercharger will get to full boost before a turbocharger will! But you are correct 10psi on a supercharger is the same as 10psi with a turbo

Not really. Superchargers *should* be sized so they develop boost progressively. If one is getting boost too low, it'll run out of steam at the top end. Go drive a Supercharged Pontiac Grand Am. You'll see what I mean. Tons of balls for squirting around traffic, but NOTHING up top (obviously using a too-big pulley on a too-small compressor for an insta-6 psi). Feels like the HP curve of a stock KA. Blah.

this is a bit off but have any of you guys seen the z33 fairlady with the rb26dett in it? i was just wondering cuz i read about it in some japanese magazine.

i actually wish that the R would still be a straight 6 engine. i prefer the exhaust note of a I6 over a V6. it sounds much smoother. also thats how its been since way back inthe day.
