3.0L twin turbo i6.
After reading about how Mazda is thinking about using a smaller engine in their next Miata, that got me to wonder if Nissan is finally going to use a smaller engine in the Z car next tine around? I'd like to see that already since it's just not the same car the original 240Z was, especially since it's 1100 pounds heavier now I understand how you can blame lots of the weight on safety regulations and consumers not willing to accept a raw bones car like the 240Z originally was. None the less Nissan can still trim lots of pounds from the Z now. Even one of their 4 bangers could crank out more horsies than the original 6 cylinder used in the 240Z(151 horsepower and 146 pound-feet of torque). Although if Nissan did use a 4 banger in the Z now, I get the feeling it would be the FRS/BRZ's new competitor. I can live with that though. Nissan is probably safer though keeping the 6 under the hood. I still wonder if they're going to bore out the engine again though
Everything I have read has indicated that Nissan will continue using a variation of the VQ engine.
Might they reduce displacement? Perhaps. More than likely, however, it will stay at 3.7L, but they will increase the horsepower a bit and add fuel-saving functions such as those found on Mazda's Skyactiv engines.

There is 40 years between the two cars. Please name a production car that has been around for 40 years and weighs the same or is within 10% of its original weight?
The trend will continue and the number will be greater. Look at the history: 2.4/2.6/2.8/3.0/3.5/3.7
Can anyone tell me WHY they increased the displacement each time?
Here, I will help. It is because of safety regulations and emissions. That is the only reason the 260Z exists. They bumped up displacement to compensate for added weight and emissions choking out the engine.
Get rid of the long hood? You said yourself, "wouldn't resemble a Z car then" why would Nissan want to make a Z that didn't look like a Z???? And it was a rip on the Ferrari not so much the Jag.
As for your last point, the cars available were completely different back then. As was the market. Comparing apples to Llamas. You won't see that happen again.
From what little we've heard from Nissan/Infiniti, the next G motor will be an evolution of the current VQ37 with a revised head and direct injection and possibly a small bump in displacement. Whether it's also slated for the next Z or not is up in the air, as Infiniti is really trying to seperate from Nissan.
In the interview with MotorTrend the Infiniti source confirmed an evolution of the current VQ with DI and revised head, and someone who works for Infiniti who frequents the G forums also confirmed this.
Have you driven the 370Z? People are obsessed over a number that is honestly unrealistic when you think about it.
People want cars with options, the best selling cars are usually those with options. Especially in the target market for the Z. If you want to remove the radio/NAV/multi-speaker setup, power windows, power/heated seats, luxurious materials on the interior, sound deadening etc. then yeah you could hit a lower target number. But to meet the safety standards and stuff 6 airbags and active head restraints as well as the expectations of customers with sound deadening and technology weight is inevitable.

In 1973, the Mustang 351cj weighed ~3680lbs 'dry' with 266hp/301ftlbs.
Today, a much faster V6 mustang weighs 3400lbs 'wet' with the much more powerful V8 GT weighing in at 3533lbs.
I think a Ford Mustang certainly qualifies as one of the most common production car of the last 40 years.
