New Gtr

As the title says, Looks like the GTR is on the right path to become the best/fastest car to roll off the production line!
It’s reporting that an unofficial hand-timed 7m 38s shows the GT-R’s skinned the Turbo’s official 7m 40s, making it one of the fastest production cars to ever loop the Nurburgring’s notorious Nordschleife.

"One of the fastest" is not "the fastest". And, as I said in a previous thread, its still more than half a minute off the production car lap record.

something that irks me to date is why they insist on retaining the Skyline stovetops if they want to break away from teh Skyline lineage with the new GTR.

It has been written that a senior engineer in charge of development and design stated that there will be no GTR without round rear tailights....

grabbed this info to add...

Holiday Auto has been hard at work putting together a 10 page article exploring the new GT-R’s engine, chassis, driveline and interior features, some of which is old news by now but included nonetheless. We’re told that Nissan was in fact looking at a V8 engine to use in the GT-R in its early stages of development but found that the VK45 from the Nissan President wasn’t an engine worthy of the ‘R’ in the GT-R’s badge. Although it could satisfy the power, torque and driveability deemed necessary for the GT-R, the way in which it delivered those attributes was more befitting of a large saloon than a GT car. There was also a status problem, the VK45 being associated with Nissan’s luxury sedan would cause problems with potential GT-R buyers who were looking for more exclusivity… well exclusivity is what they got.

The VR38VETT

Holiday Auto broke the news about the existence of a VR based GT-R engine last month, and since then has gone one further and given us a actual alphanumeric designation: VR38VETT. The VR38 is actually a recreation of the famed VRH35L V8 powering the R390 Le Mans car albeit in V6 form. A lot of knowledge gained from Group C and endurance racing has allowed Nissan to take the performance aspect of the GT-R that little bit further (over say, a VQ based engine) by taking the basic design of the VR38 and using it for the new GT-R’s V6 engine block and cylinder heads. A surprising feature of the twin turbo system is the ‘Integrated Exhaust Manifold Turbine’ where the exhaust manifold and turbo exhaust housing are formed as one piece. We’re told this is for weight saving, packaging and high response and was chosen over the more costly ‘motor assisted twin turbo system’ that was predicted way back in mid-2004. What all this has resulted in is an engine design that could be viewed as two 1.9L straight 3-cylinder DOHC turbo engines joined by a common crankshaft, with separate intake manifolds and throttle bodies for each bank. The intake manifold is actually the centerpiece of the engine bay, its intake runners being used as a design feature of the VR38VETT as shown in the CG mock up image shown below.

Cosworth’s involvement in the GT-R’s engine development has been mentioned before on many occasions but until now there hasn’t been much information on what they’ve actually done. Holiday Auto tells us the GT-R’s aluminum engine block is a ‘monoblock’ design, meaning it doesn’t use sleeves inside each cylinder bore so that the pistons make direct contact with the block. Cosworth has also reduced the weight of the crankshaft, conrods and pistons to achieve maximum response and a free revving nature that belies its larger 3.8L capacity. It comes as a surprise too that the whole engine looks a lot shorter than what you would expect a 3.8L engine to be, its compact design and light weight being a major contributing factor in the cars overall balance. Many other parts such as the cam covers, timing chain cover, oil pan and a multitude of bolts, screws and washers are all made of magnesium. The GT-R will also use a semi-wet sump system which can handle higher g-forces over a traditional wet sump which start to suffer from ‘oil sloshing’ at around 1.8g. As pointed out in our previous article, the power delivery of the VR38VETT is extremely linear and does not drop off after hitting maximum power at 6,800rpm which was a big factor in proceeding with the development of an all new engine. From as little as 1,500rpm a powerful surge can be felt with - what seems like - all 480ps available with very little throttle application. It has been said that there are very few people with enough skill to drive the new GT-R at its limit, this limit being so high that a driver of average skill level would never be able to test the boundaries of the GT-R’s performance… this could possibly be an exaggeration on Holiday Auto’s part, but the point has been made clear: the new GT-R is every bit a Supercar.

yer but it also says it has Blembo brakes.. i wouldnt trust a magazine much until the actual thing hit the streets or actually went to a magazine like i dunno... motor magazine? wheels? but on an international level??? whats a really really big world wide mag??

otherwise, theyre just rumour mags... it is meant to weigh in the 1700kgs+ thou :thumbsup:

i just dont know about the "blembo" brakes lol

Seems its a bit heavier than the 1740kg

I know they call Porsche's 'Porka', but if that's the official weight of the new GTR, we might just have a 'Porka' vs. 'Porky' show down. :D

The GTR doesn't sound like the most entertaining car from a complete stop at that weight. Hmm. Have to weight and see! :thumbsup:

imo this car looks nice and all. may or may not hold the nurberg record for 'production' cars. but at the end of the day weight is the major factor.

this car will have lots of power and performance for a 'production' car. what interests me more is how this engine will fare for aftermarket upgrades - will it even be able to hold the same hp as the old RB???? really not so sure on that one.

will look and feel great but wont ever be the toughest street or track car out there from the range currently available.

plus imo, you can't beat manual. 1/2 a second quicker changes????? a lazy man changing gear maybe? if you want no stall then you don't need your clutch and you can't beat the selection from a manual- unles thisnew gearbox has some really fancy shit and knows what corner lies ahead before you get there...

    • So.... when I'm finally getting around to having my power steering leak sorted, now it looks like I've got the same issue most A/T Skylines are having. My A/T light will randomly come on and I'm stuck in 3rd gear until I turn the car off and on again. Only 3 weeks ago I did a complete transmission service: Oil flush + new gasket + new filter. This came out of nowhere!! It wasn't like the car was driven hard. I drove about 3 mins down the road to get fuel and boom!!!  Anyway, I have a few questions and hope you fine people can help me out here. All questions are in red. 1. The solenoids: I was looking at the parts catalogue in Amayama and I could only find the Solenoids as an assembly. https://www.amayama.com/en/part/nissan/319404ax05 I read in another thread that Solenoid A = 31940-4AX02 & Solenoid B = 31940-4AX05 but the Amayama product has only the code of B. Is this the right part? Can anyone who has done the Solenoid changes or seen them confirm if this is the complete set of A & B?   2. Gasket and Filter: I'm not going to try change the solenoids myself because it seems difficult to do in a home garage with just 2 jack stands. I plan to take it to a shop and get it changed. I was also going to buy the transmission sump gasket at the same time so I don't reuse the same gasket. Should I just use the existing gasket as it has only been on the car since OCT 19th? (~3 weeks) Should I be buying a brand-new gasket and a filter? Does this job involve taking the filter out?   Thanks in advance to everyone. It's hard to find a video of someone doing a solenoid change on a R34 so any help you can give answering my remaining questions would make me less stressed.
    • Yea - From what I have seen from the video, the car idles like any R34 lol 50PSI of fuel pressure is hardly super abnormal, the regulator is working because the pressure remains static when the throttle gets revved, i.e pressure remains the same when manifold vaccuum changes. Bigger pumps on stock rails always bumped the pressure in the rail without using an aftermarket regulator to change that. Do you know what your IAC is actually doing? Has there been any data showing the stepper motor % etc? There's no way your idle is actually moving around the way the cluster(s) are indicating. You would hear the difference with the engine RPM flying to 3k and 1k in mere seconds. I'd be checking the wiring to the tacho. What the tacho is telling you and what the engine/ecu is telling you are different things. I assume your ECU doesn't display the spike. So whatever is telling the tacho to be at X rpm is doing something weird. When the going gets insane, you're on the wrong path. You've ruled out plenty of things that are working correctly/aren't the issue. Your idle isn't doing what the tacho is indicating. You have two seperate issues, I don't think they are linked, and the idle seems reasonably okay unless it's stalling which.. well, it hasn't. Troubleshoot the stall if it occurs by figuring out what your IAC is doing vs what it is being told to do.
    • So awesome! I love the RB with the exhaust on display.
    • NO HITS PRICE DROP   ENGINE - $8.5k ONO TRANSMISSION - $1.8k ONO  
    • If it has had a code in the recent past, the code should still be there waiting to be read.
