Vq30dett Vs Rb26dett

[TeamFL1]

OK forget what i said about VG, but why VQ30DETT is in a hooked up 350z or the JGTC Z cars. why not twin turbo the 3.5 that we have... i seen it done but i don't know how much power it can make. The new skyline R35 is probably be the vq35dett....i hope so. the Ferrari 360 is n/a or twin turbo n yea it is 3.6 liter, i don't study cars at that price range. but if the 360 is twin turbo..... then the new skyline is in the game, if it makes ummm over 400 hp? 350 be nice but 400 is the way

The 3L VQ revs more smoothly than the 3.5L and still gets the job done. NISMO has already clinched the JGTC title this year. In addition, the 3L was already available turbocharged from the factory, in the JP market Cedric and Gloria twins.
Finally, you have to have a little something up your sleeve. Why go all the way, if you can sandbag and still win? If the competition comes up with something better in the future, then NISMO can worry about using bigger VQs.

The GT-R's engine will probably not be 3.5L. There haven't been any rumors with that displacement for a long time. Most information has been pointing to a 3.2L, which could be a destroked version of the 3.5L. Power could be as high as 480ps(~473hp).

The now defunct F360 was NA with ~400hp. It's replacement, the new F430, produces 490hp, but 'only' 343lb-ft. The turbocharged GT-R will likely have more torque. While the Ferrari is a great car, the GT-R's real target is the Porsche 911 Turbo.

TeamFL1... I would like to introduce you to VQuick. He has probably the most efficient, and reliable information out of anyone that inhabits the Nissan section. You can learn a lot by listening to him, as I have.

All of what he said was pretty much what I was thinking... I personally think Toyota has something tricky for next season, and I think NISMO (Nissan Motorsports International) is going to combat it with something awesome, I dont know what, but I cant wait to see

Maybe a highly tuned Naturally Aspirated VK45DE? That would be nice.

I don't understand why Toyota tried to go with the V8s. Almost seems like a step backward. The 3SGTE I4 was lighter than the 2JZ I6, could be better positioned in the engine bay, and could make just as much power(class is limited to 500hp), albeit at the expense of torque. The aluminum 1UZ might weigh a bit less than the 3S, but who knows what torque output is like with an NA powerplant.

If Toyota tries to pull anything(turbocharge their new truck V6, the 2GR or something??), NISMO can just fire back with a bigger VQ. Heck, NISMO can still go up a full liter on the VQs if they want. As it is, I wouldn't be surprised if the turbo VQ can make more torque than the NA 1UZ V8. If NISMO stays FI, they'll probably have better torque than than the V8, while weighing less.

Toyota sucks , that all i can said, but I don't know how many Toyota have won a champinship, but I see skylines all the time. and NSX, LOL what is that? Nissan makes the best performance cars out of Japan, thats my opinion. they have the S13 14 15, skyline, the Z, and Toyota? MR-2 Supra /we talking about big names / so forget about your crolla a86. Honda i think its the s2000 and NSX. so which company has more serious sport cars? NISSAN hands down!!

Nissan, Toyota and Honda are pretty much up there. but in JGTC, its tied with Toyo and Nissan.

the nissan owns in Jgtc. Personally I think they should have put the Vq in the R34 and see how well that did. Is it true that Vq broke at 400 hp.

Yep. They took the 2004 championship, clinching the title before the season was over.

They did that in 2003, and took both the manufacturer's and driver's championships. The VQ30DETT-powered R34s were much better. The engine is short enough that, when placed against the firewall, it basically made the R34 a front mid-engine car. This meant better weight distribution. Drivers loved the improved turn-in, and the lower weight of the VQ vs the RB(probably at least 200lbs difference) allowed engineers to place ballast elsewhere in the car for even better weight distribution.

Then in 2004, we saw the VQ used in the Fairlady Z. Since the car was pretty much designed around the VQ, it was able to put the engine to better use. Toyota stepped 'up' to an NA 5.2L V8 for their Supras, and they didn't even make a dent in NISMO's armor.

Is it true that Vq broke at 400 hp.

Probably not. Street VQ30s are making more than that on stock internals, which includes rather boost unfriendly 10:1 pistons.

[tyndago]

The VQ is a good motor - all aluminum - 3.5 liters of displacement stock. They probably run the 3.0 liter for the extra weight advantages of less displacement.

More displacement = more torque.

The VQ head is supposed to be better than the RB head - flows more.

Stock the rods in the VQ are not as good.

Stock iron block vs aluminum block - the iron block wins, but the VQ has already been fairly proven.

Have a look at Performance Motorsports Pro Street Tire VQ35 powered 350Z. They went 8.3@176 mph last year. Impressive. Expect more this year.

[VQuick]

Thanks for the additional info! I forgot about the Performance Motorsports 350Z.

I think it would have been pretty cool if the NISMO R34 GT-R Z-Tune had used a VQ like the 2003 JGTC cars. Would have been a nice sendoff for the R34, and could bridge the gap between it and the R35/36.

Well if I had the money I'd try that R34 and drop a Vq in it. Guarenteed to make the cover of tons of mags.

Let's not forget the real reason behind JGTC and the GT500... why do you think manufacturers and tuners are so interested in this series? Why spend millions and millions on race cars?


R&D, baby...


Is it such a big surprise that Nissan/Nismo is using a VQ30DETT in the JGTC. Do you think it's a coincidence that the former R34 GTR chassis had a CQ in it too? Nissan/Nismo is using this engine in different chassis' from the R34 to the almost perfect aerodynamic Z33... these cars are merely test-mules for Nissan Production Prototypes. Doesn't a VQ30/VQ32DETT in the new GTR make perfect sense now?

As for Toyota using NA V8's... well, this is all R&D too. Those engine are being used in the Luxo-Sport Sedans and Big Luxo-SUV's currently in the Lexus line-up. Don't be surprised a TT V8-V10 series pops up sometime soon (new Supra).

A super Nissan Natrually Aspirated V8 would be nice! Ala open-wheel IRL VH45 powered cars!

Actually, Toyota is using a bigger V8 than what is in production now. The Supras have a 5.2L, compared with the 4.3L out now. The 5.2L or something similar should be produced seen. We all know the Tundra could use a bigger V8(Only 245hp in a full size? Get real!), and the Lexus LF-C supercar will probably be one of the other cars to use it.

The IRL cars use the same block as the VK45(VH is dead), but the engine is actually smaller. The VRH35L is only 3.5L, and is turbocharged, running on methanol fuel. An NA version probably wouldn't make much power, or be very streetable(revs pretty high).

Seriously i think vquick should be a mod for this new forum.
he knows more than most people working at nissan now lol. Zedex, how can we recommend him for the position hehee?

Actually I was reffering to the older cars... but I had no idea the new cars ran a VK. Thanks...

I second that!
