Vq30dett Vs Rb26dett

[charlzneon]

the latest news i've heard is that the new Infinite GTR's will have a 4.1L v6 engine

[jcsaleen]

Sources report that the 2008 skyline will be built on a unique awd platform and power by a twin turbo version of the 350'S 3.5 litre V6, possibly bored out to 4.0 litres. The Grapevine speaks of 450 hp allied to nissan's next-generation, variable Torque split, ATTESA E-TS all wheel drive system. - Auto mag

VQuick, you seem to know quite a bit about Nissan cars and engines, what do you think about dropping a RB26dett into a 240sx (s13 or s14) i've seen it in some magazines and was curious. I've looked at JDM , a price for a RB26dett with harness was about $3500, do you know of anywhere cheaper or more reliable?
I would greatly appreciate your thoughts on this mainly because I know the power that a RB26dett produces and i am a bit weary of that power with the weight of a 240sx.

Just purchased a sandrail with a VG30DET JDM motor. It has twin Garrett turbos and was dyno'd by the previous owner with 13lbs of boost at 380HP at the rear wheels. I'm looking for a source to get engine gaskets for this engine. Any help would be appreciated. I may be selling this to upgrade to a V-8.

The only rumors I have heard on the GTR is that the engine will be one of three types, or multiple engines based on market, the main contenders are a street-legalized version of the VQ30DETT race engine used in the current JGTC Fairlady Z's. In current form the engine makes 480 ps (~473 hp) unfortunately, I don't have any numbers on it's torque. Another contender for the engine is, as VQuick mentioned, A destroked 3.2 L VQ35DE, probably with forced induction of some sort and a lower compression ratio, I don't really have any info on this engine other than it may exsist, if it really does, the guys over at Nissan are being very secretive about it. The final contender is some version of the VK block. The VK block is very capable, being a V8 based on the VQ's technology, rather than the previous VH's technology. The VK45DE as it stands is rated at 335 hp, 333 lbs/ft torque in the US model M45 (slightly detuned from this number in the Q45 application), and is probably not even being utilized to it's fullest potential. One good example of the VK's potential is the ImpulPower VK45DE, a stroked, bored 5.1 Liter of the VK45, still natural aspirated, Impul's version makes about 370 ps (365 hp) and 53 kg/m (383 lb/ft) although these are Impul's numbers and I am told they are somewhat conservative. All 3 engines are aluminum/aluminum, and use state-of-the-art in Nissan's engine technologies, so I don't see why any one of them wouldn't make a good solid engine for this next generation of Nissan's halo sports car. As a side note, for the people that were quoting the 276hp number for the VQ25DET and the VQ30DET, it is important to note that those are Japanese MANUFACTURER numbers and it is a longstanding tradition and a gentleman's agreement among Manufacturers in Japan that no vehicle is released from the factory with published power greater than 280 ps (276hp) despite that, most cars rated in japan at 280 ps, are truly putting down more than that.

P.S. Please don't compare the VK to toyota's UZ series V-8... it's really poorly designed, Toyota needs to stick with I-4's and V-6's... they can't design a decent V-8 to save their lives.

As an aside, I don't post much, but that's good. I tend to be long-winded and vehement about my position on things.
