True, but what about fuel delivery? If they keep the naming convention like this (and like the HR motors), I guess they intend to keep us at multiport FI forever...

 

I was referring to the actual runners.. in this pic:


You can see how the left side runners are horizontal, then point down, the right side immediately goes down.

 

z06 yes it is an excellent preformer but if i had a choice between this car and the z06, the gtr would be the obvious choice even if it was slower.

Its not all about going fast....

 

I'm going after motorcycles when I get one. Forget Z06's.

 

Yeah you're not seeing things, I can see that in both pics now that you say that, the charge pipe on the drivers side looks like it's higher up as well. Probably just had something to do with fitment/clearance issues.

 

It definitely appears that way but d@mn. Even with a solid mounted motor vibrations would kill that weld after time unless the boots between the BOV pipe and the TB were extremely supple. I think the pic is playing with our eyes.

 

Go Back and look at the first post... the charge pipe is not welded to the strut tower...

 

I don't really see how they could name it any differently. It has DOHC, but it also supposedly has VVEL technology. If that's the case, it would need a V somewhere in the name. Couldnt be VR38VETT, because that would refer to the Neo VVL system, a la SR20VE. It would be VR38VTT if anything, but since I'm assuming this is going to be the only VR-series motor nissan produces for a while, there's no need to make that distinction.

 

Hmm you're right, that's really strange.

It also looks like the same effect looking up the right side and down the left side, in increasing level of "immediacy," or decreasing level of curvature.

Considering the intake system is almost symmetrical, I can't think of a reason for that.

 

I'm pretty sure the Cosworth engineers involved with powertrain development could come up with a couple.

 

you can also go on record to be the first one to try.....

 

Lies. All LIES!

 

Brace yourselves.:

 

Best quality pic so far. Awesome.

One Q about cars in general these days. Why is there still coolant running to the TB's? Since the TB acts as the IACV these days the plate would only be fully closed when the motor is off. If the concern is about the plate freezing in the TB an electric element would be faster for thawing it; no? What am I missing? Seems like an unessecary complication.

 

I believe it does 2 things:
1) keeps the TB warm so it doesn't freeze up in the winter seasons.
2) warm air mixes better w/ atomized fuel

Seems like every car on the market has coolant flowing through the TB.

 

dang. did you snap that pic yourself terry? just kidding. looks nice.

i also don't really understand why you need coolant to run to the TB.

 

I wish.....

 

Here is a really large close up shot...http://img516.imageshack.us/img516/9539/jap3ba7.jpg

We should all keep a close eye on these technologies developing before our own eyes. The new Nissan Maxima will be just around the corner and I can bet they will try very hard to retain the 4DSC name back where it belongs. The press indicates that the new Maxima will use similar technologies in engine development not only meet ultra low emissions standards but with power and performance to boot.


Back to the VR38DETT...
Those IHI turbos must be impressingly responsive due to the lack of restrictions. With fully independent intake and exhaust systems which are symmetrical must help aswell.

Also..

 

One piece turbo/exhaust mani FTW

 

Needs external wastgates that reintroduce the exhaust 18 or more inches away from the turbine housing. Needs equal length ex manifolds and true dual exhaust.

There are some more pics if you guys are interested.

 

hahaha

 

Wow!! Those latest pics of the drivetrain have changed my mind about this thing. I now bow down to it. Nissan stepping to a rear transaxle is freakin awesome. Can the driver controll the rear bias in these or is it always automatically controlled?

 

^I believe I read it can be controlled anywhere from like 50/50, 20/80 to full 100 % rear bias.

EDIT can't find where I read it, maybe Ghosn said it during the Tokyo motor show, but I do recall reading or hearing it will have some type of controllable bias implemented.

 

There is no user controllable front/rear torque split.

 

Now we know why; the left side runners are sweeping towards the rear of the car whereas the right side are sweeping towards the front. It just looks as they're a different shape because of the perspective of that picture.

 

Just to beat a dead horse http://en.wikipedia.org/wiki/Image:N...T-R_engine.jpg

 

I'm in love with this car. Unfortunately it's a little out of my price range...

The VR38DETT Nissan says is a completely new engine from the VQ - but engineers beg to differ saying it carries a lot of the same designs as the VQ.

Essentially what we have here is an ultra refined VQ engine.

 

ich habe better cut away pics

I'm no Skyline fan boy, but I have to say I want this car bad!

To me it would be like driving a VR4 on crack! I been on a hand full of 500+awhp cars and let me say its like nothing else. Not even a 500hp vett is as fun. The control you have is out of this world.

I'm looking foward to D-day... its going to be awesome. I hope I'll get the apportunity to sign on the dotted line for one of those... since after I hear it was coming to here, I didn't get my vett. Time to start saving now huh? Hahaha

 

Lack of equal length mani tubes leading into the turbo FTL

Nah, that's trivial; this is one hell of a car.

 

the only thing that drives me crazy is the rear quarter windows. Why in the hell didn't they make them follow the body lines like this:




Versus this:



OT i know, carry on.

 

Because that would push the MSRP above $70k

I do agree though, those windows look a lot better. Now it looks a bit more Porsche 911 like.

 

Because the insurance companies pushed for Nissan to make the C pillar and thus blind spot bigger and give them another excuse to charge higher premiums.

 

As if that car needed any more reasons to raise the premium

 

Guys, there is a thread (actually a few of them) in the Other Cars forum for general discussion concerning the GT-R. This thread is for discussion about the engine and anything related to it. Please keep the posts as such.
