The only other person i know as knowledgable about VQ's other than Matt.. is another Matt (SR20DEN on the maxima forums) and when i say know the VQ.. they know it bolt for bolt and know exactly what will happen with the motor.

Maxima's are slow.....
Brian are you going for sure? Neal told me about going to US41. If I go, can I borrow ur ET streets?

Vq35 uses a 48mm big end journal, IIRC. That's why this is such a good option. Pretty weird size which limits available bearings(only used on a 4G63 and SR20det that I know of). Where the 50mm is used in many more applications.

This thread is retarted. My 1986 300zx has a VG30E which is the predecessor of the VQ. They are very very similar motors. Maximas are cool, they barrowed a lot of technology from the Z33 like the suspention for example.

We are talking about a VQ30det. Not a VG. Who's retarted(especially in reguards to spelling) now. JK. Just having a little fun, not bashing you.

vq30de (dual overhead cam 24v V6 alum block/heads with chain driven timing)
vg30e (single overhead cam cast block with belt driven timing)
Far from similar.

I believe the main point of the thread was to point at a different setup for the VQ engine, regardless of what type of car it is/was in.
One of the main gripes when the 350z first came out on Best Motoring by japanese professional drivers was that the engine did not have the characteristic high-rev ability seen in most sports cars (I believe the porsche GT3, skyline, s2000, NSX and others all rev past 7500 rpm)
Many others entering high boost or horsepower applications have gone the route of reducing displacement in order to have a safer and higher rev capability. Such is the case with 1) Jim Goughery's 350Z, 2) Top Secret VQ32 350Z, 3) JGTC, and 4) Dallara Lemans Prototype VQ30DETT - i don't think many know of this, although I think they ended up increasing displacement later on
http://www.mulsannescorner.com/dallaralmp11.html
And yes, the fact is that most will not opt for this nor a 8000 rpm rev limit since a simple ECU reflash will compensate up to 7100 rpm. Most people would not opt for cams, rods, or pistons either but that doesn't mean no one should make it or put it in their engines. A higher rev limit also is important on a road course, allowing you to maintain a specific powerband given the gear ratios of the transmission during turns and technical sections.

The JGTC engines are not high-revving, neither is the VQ in that prototype you posted. I haven't seen anything to prove that TopSecret uses a 3.2L in its project car except from a SuperStreet article, and I don't think they have any idea what they're talking about. I had no idea Jim Goughery altered discplacement. The only example of a high revving VQ, that I know about, is the old formula nissan engines that topped out just over 10,000rpm. They were a modified VQ with 3.0 Liters.
Swapping out the DET crank for stronger rods and shorter stroke, with less compression might be a good, cheap way to build the motor for boost, but for revs, the rod/stroke ratio is about the last thing to consider for building for high revs. I think the biggest advantage to this, besides the low compression, is ditching the CVTCC system. This doesn't require changing the crank obviously, but putting the VQ30 cover on and using pins allows a low compression 3.2L that can now be tuned using a JWT ECU. This is the best part of the package IMO. No more piggybacks or expensive stand-alones, and JWT has dyno pulled just about every cam and boost level for the optimum- and safest- tune. This together is pretty enticing..and of course with Z33 cams and the better breathing head of the VQ35, I would be impressed to see what's ultimately possible in a Z with this configuration.

I believe the JGTC VQ30DETT revs up to 8000 rpm, with a 12:1 compression ratio. I'll have to look up my sport compact car issue again.
However my conception of high-revving may not be the same as yours since you mention 10,000 rpm on the old formula nissan engine. As for the Top Secret car, well its hard to find hard information on that. The super street article just mention that its a destroked vq35 with a VQ30 crankshaft
Jim Goughery didn't actually alter displacement. He opted for a VQ30 instead and used a modified maxima manifold for a little bit also. He sent pics to a friend once that requested it from him on another forum.
