2007 Nissan 350Z VQ35HR - I may just have to get another.
This was the release notes on the '07 G35 but it will pretty much be the same for the '07 350Z. Supposedly it will be much lighter than the '03-06's too. I'm interested in seeing this new "twin ram air intake" and new exhaust. I guess I may be going back to a Z after all. 
The VQ-series V6, which has been named one of the "Ten Best Engines" by Ward’s Auto World magazine for 12 consecutive years, now moves into its fourth generation and has been significantly rethought, with approximately 80% of major parts (except bolts, O-rings and clips) redesigned. The block features ladder frame construction for greater rigidity, crank journal and pin diameters have been increased, the block height increased by 8.4 millimeters to reduce piston side force and the engine center is now 15 millimeters lower, which also contributes to the G’s improved dynamic performance.
Other engine enhancements include the addition of standard variable exhaust cam timing (eCVTCS), a higher rev limit (increased from 6,600 rpm to 7,500 rpm) and higher compression ratio (10.6:1 versus the previous 10.3:1), asymmetric piston skirts, twin knock sensors, improved coolant flow and new Iridium spark plugs.
A new symmetric twin ram air intake system helps reduce airflow resistance by 18% and a new exhaust system design with equal length exhaust manifolds and reduced muffler exhaust pressure (25% less than the first generation G35) help improve engine breathing. Both are tuned to create authoritative harmonies, helping enhance driving pleasure.
The result of all these changes is an estimated 300-plus horsepower and a powerful torque curve (final horsepower and torque figures will be released at a later date), an exciting engine sound and expected improvements in emissions and fuel economy.
The new VQ engine design also includes a long list of advanced systems found on the previous design – including a continuously variable valve timing control system, a "noiseless" timing chain for quiet operation, an electronically controlled "drive-by-wire" throttle system, microfinished crank journals and cam lobes, and molybdenum coated lightweight pistons.

So I know what to wait for
07 350z owners who went TT and sell their OEM Headers
However, for the new motor, I think i'll be SAE corrected HP and TQ will be lessen the 06 specs even though they're all the same stuffs - Well, at least its only on the paper. Well, that's what they said for the 07 G35 Coupes.
