i think that it should run on Nitrous only. fill up with 18 gallons and you'll get where you're going before you leave

I like the rational of the detuned VR engine. It seems that the VQ has been maxed out. I don't know that much about the VR engine except that the TT version of it in the GTR is the only production version of that engine. I wonder what kind of power it produces without the TT setup. I wonder if it would be possible to put a non TT 4L VR engine in the next gen. Then it wouldn't really step on the GTR since there aren't any turbos. All that dreaming aside, I dont know enough about that engine to know if that could be a reality.

Me too! HAHA! But the fact of the matter is, it's 2010 and they already have this kind of technology knocking at the consumer door.

It won't be long before congress legalizes marijuana and we are driving hybrid and electric cars :rock:

Nissan won't be borrowing any of Mercedes engines, those are all rumors are heresay. The Daimler alliance is about sharing EV technologies, Daimler has no in house EV technology so they are going to utilize Nissans. Nissan also wants to maximize its production of its new battery technology to recoupe development costs and be considered the industry leader in EV production. Nissan produces more V6s at a cheaper price then Mercedes can, Nissans V6s are more potent, fuel efficient, and reliable. Nissans V6s have been class leading for many years now, no reason to "downgrade" to a Mercedes engine.

Nissan won't use the VR has its cost of production is to high(its partly hand built), the Z will continue to use a mass produced V6 similar to whats found in other future Nissan vehicles. The VR is also meant to be "special" in a way by only being found in the GTR, putting it in another vehicle would take away some of the uniqueness of Nissans supercar.

I would expect Nissan to adopt direct injection on their next generation V6s. They very well may continue to evolve the VQ line as it has largely been a success for Nissan both on the cost efficient side of things as well as the power/fuel consumption side. I don't for see displacement getting much if any larger for Nissans V6s as the CAFEs fuel economy standards are only getting stricter. Direct injection would help fuel economy and torque production without increasing displacement Nissan is likely to incorporate their "DIG-T" technology found in the new MR16DDT engine in the Juke. DIG-T stands for Direct Injected Gasoline Turbo-charged, Nissans new MR16DDT has proved that this technology is both fuel efficient, good for making power, and cost efficient. I'd expect to see displacement in the 3.0L-3.8L range with something similar to the DIG-T configuration.

They should allow us to tap the VVEL.

Sorry but I just had to say that the rumors are not hearsay. Hearsay is used in courts not on the forums.

I believe this is the road ahead too. I'm still wondering why Nissan hasn't incorporated gasoline direct injection in their higher displacement cars yet. Even the GT-R is still conventional EFI, I believe.

IMO the Z with a 380-400hp turbo or V8 would be ideal at it's price range...then it would be in corvette land.

Nissans new 5.6L found in the Nissan Patrol/Infiniti QX56/Infiniti M56 has Direct Injection and makes 420HP/417TQ.

The new Juke will be DI also, smaller engine, but more testing

Oh, that's right - +1 rep for ya on reminding me of that one!

i would LOVE a direct injection turbo. MMMMMM :tup:

I'm going to bet that like the M3 Nissan will downsize the engine and make up for the capacity loss with turbo's or superchargers...

3L Direct Injection v6 with a turbo would be fantastic...

I would rather see a slight reduction (destroke to increase redline) in displacement with two small turbos and direct injection. Keep compression high for power and small turbos for rapid spoolup.

thats exactly what i would love to see... but knowing nissan :shakes head:

It makes perfect sense. Smaller displacement=less fuel consumption, higher compression=better efficiency. Direct injection allows this. When you think about it it is the best all around solution.

Nissan is always listening to what the people want, however they find a way to get it to you in a "cost effective" form. Most likely, whatever the uprated Altima and Maxima get is what will make it's way into the Z. And Maximas and Altimas are selling like hotcakes............

my perfect engine will be a VQ37VHR but with downsize rods to 3.5L, with turbocharged direct injection, ufff sex...
