The 370Z still isn't light, and listing a bunch of heavy cars doesn't make it light either, save for relative comparison to those cars. It's not about math, it's about weight.

Now maybe you just aren't aware of what is considered normal weight. It's fine. I've owned quite a few cars and have good points of reference. For the industry, three thousand pounds is considered a normal sized car. The majority of cars are on the big side. Which means that the Z probably finds itself closer to the average size of cars that are much larger. No one would argue that any of those cars you listed aren't heavy (except again, perhaps relative to other cars you listed). Also, no one would argue that the Corvette is light, much less VERY light as you said the Z is and the Vette is 100 lbs lighter than the Z.

Your numbers are close, but still a little low. The 370Z Touring/Manual has an actual curb weight closer to 3330 lbs. Want proof? Forged Performance weighed their car on corner scales with nearly a full tank of gas (which is how you are supposed to measure curb weight in the States) and got 3323 lbs. Top off the tank and see where she lands (hint: it's more than 3323).

Now, this thread isn't about weight. If you want to continue the discussion of the 370Z's weight, please feel free to start a new thread and PM me to take part.

As for the 20G, I had mine on a 2.3L stroker on my 97 Eclipse GSX. That thing spooled very quickly and never ran out of steam. I ran it at 21psi on 93 octane here. It's kind of conservative, but I prefer to overbuild and underrun in order to add longevity.
