Holiday Auto Magazine Print Next Gtr Engine Specs?


Recommended Posts

Could this be yet another Japanese magazine printing a wish list + photoshops as an article claiming to be the real specs or will this be the final engine spec??? Who knows:

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.

Hey i see they're using those new "blembo" brakes i hear so much about

Less torque than a 911 Turbo, and heavier :)

not looking good

p.s I notice the price for a GT-R comes out at $142,250 if you take the values of each in Yen, and then transpose the price of a Turbo in Australia into the equation. hmmm....

Don't get too depressed, those are just Holiday Auto's estimates. They said themselves that it was what they expected the specifications to be and might differ slightly. How much? Who knows... just wait until the end of next month :)

I find the second half of that paragraph to be a bit specious, though.

Firstly, the R390 hasn't been raced since 1999 and no-one else has used that block for racing since. So that's almost 10 years of no R&D for racing applications. The game as moved on a lot since 2000. The VRH block is based on the VH45DE, which is still in production....in luxo barges.

Hardly a test bed for a supercar engine.

The VQ block, on the other hand, has been the SuperGT powerplant for Nissan since the RB was removed from the GT500 Skylines in 2003, and continued in the FairladyZ's. The VQ30DETT is currently Nissan's engine of choice in Japan's top-tier motorsport category.

Given that the VQ is the current "racing pedigree" design, and doing quite well, I'm not entirely sure I can see how the abandoned VRH gives Nissan "more performance headroom".

Did you also not read this part:

...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.

... it's not entirely about super dooper RB26 busting performance. Exlusivity plays an equally big part as does ultimate performance. Thats why the engine isn't a VQ, and that's why the engine isn't a VK.

It's funny you say the VRH35L is hardly a test bed for a supercar engine when the VQ has been ditched this year in favour of a VK for the GT500 Fairlady Z. It's not like Nissan had a few 1999 VRH blocks lying around and has 'blown off the dust' and used them again 8 years down the track. The new engine - according to Holiday Auto - is a recreation of the VRH35L albeit in 3.8L V6 form with VVEL (2007 tech right there), twin turbos with integrated exhaust manifolds (never heard of that before), semi-wet sump, and Euro 5 compliant emissions. So the game has lifted since 2000? Good thing the new GT-Rs engine has too :D

Btw, the VK is based on the VQ, not the VRH (VH)

I think the pic they have in the article looks hideous compared to the ones pictured in videos recently. I'd say the video evidence is a lot closer to the mark - otherwise why would they cover half the car up? The one pictured isnt' covered up at all, which is a dead giveaway that its not the real deal.

And until now we've been told it is a VQ based engine - 3.8L twin turbo, so who knows who to believe. Nissan apparently haven't been telling anyone anything so this article is as much a guess as any other info you might read. Until the tokyo motor show this year we'll know nothing.

Yep you're right. Just one thing... theres hundreds of thousands of people who want to know beforehand. So these articles cater for those people... whether they're right or wrong.

October 24th is going to be the acid test day for Holiday Auto.

Well we all know what it looks like from this video:

Price looks to be $80k for japan.. if it ever gets released here expect a price 30k or so above that I'd imagine.

The release date in Japan for the new GT-R has been confirmed for 24th October 2007.

official pricing and has also been released in japan

Nissan dealers have said to expect a cost price of 7.7million yen in JAPAN drive away, but that does not include registration, taxes and importation to other countries, which could increase the price upto 30-40%

yaeh you have. the old holden calibra turbo had it. and im pretty sure the new astra turbo has it to. bit of an opel trick.

lol @ blembo!!!!!!!

  • 3 weeks later...

add 101yen exchange rate, that makes a 997 Turbo ~$180k AUD. They retail for $330K+

so how you extrapolate that to a GTR price is anyones guess, because going by that, you roughly double the price (53% or multiple the yen price by about 1.47 to get a rough Oz showroom price) . Making an Oz delivered GTR $115K from the Porsche calculations

But Porsche make money off their cars, i don't know if Nissan would be hunting for a net profit on just 1 unit sale (before servicing, parts, etc)?

i like that price

    • Not stock. All remade. Mostly looks stock because the pipes run to and from the standard holes in the inner guard to get to the return flow FMIC. I'm not sure which question you're trying to ask, because it seems like "stock position" vs "stock position".
    • Hey, it's a GT-R, it's just as significant a moment as mine😁 It's not ideal when things are uncertain; I'm the type of person that always has a set plan for things in life so being unsure of this plan puts me in a weird place mentally.
    • Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?
    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card style AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had no flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
    • So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?
