They would finance 100% of a $40K MSRP vehicle, though, and that would leave me with the downpayment I saved up for the Z06 to put a twin-turbo setup in the 370. I'm a flexible person with life and like to keep my options open. It seems like the issues with the FI setups have been worked out, and like I said all along, my only issue with the 370Z was the cheap paint and the lack of power. The TT kit fixes the power, and about a month ago I became aware of "car wraps", which takes care of the cheap paint. Besides, buying a cheaper car would allow me to move/do whatever I wanted a lot sooner than a more expensive one. So, will just see what the bank says and go from there.
I'll believe it when I see it

Well, we will see. The other car besides the Z06 that I have looked into is the GT500. All depends on what the bank says they will/won't finance. If they are bent on financing below the $50K limit, then the Z is my choice of ride under the $50K range. Above that tier, are the GT500 and the Z06. Been putting away $1500/mo for whatever, and am itching to get back into a sports car.

My reason for asking the torsional rigidity is because I am curious how it compares to the Z06, since that is the power level I am shooting for with a TT kit if I go with the Z. Basically, will the structure of the 370Z handle 420-440whp soundly, reliably, and over 100K miles?

I can only quote what nissan has stated when comparing to 350z which im sure you have come across:

Quote:
Front body torsion rigidity is improved by 10 percent with an extensively revised body structure which includes a new front suspension cradle to reduce front body lateral bending, new rear structural reinforcements, and an underbody "V-bar" to help reduce rear lateral bending. Additional enhancements include the use of a carbon fiber composite radiator housing and strengthening of the rear fender and hatch areas. Rear body torsion rigidity is improved by up to 22 percent and rear body vertical bending rigidity is improved by up to 30 percent.
This also has a good amount of info on the suspension setup

edit: can't link to 370z.com? weird.

Very nice, now I just need to find 350Z #'s and extrapolate. Thankyou!

/\ at those powerr levels, I'd be more concerned w/the shorter wheelbase of the 370z as a limiting factor for car control/handling (vs. something like the zo6. From what I've read, which was just quoted in this thread, the 370z is world's improved over the 350z and is a very rigid car.

I rode in a 350Z back in 2005, and have driven several 370's and agree fully!

The 370Z has a 100.4" wheelbase.
The Carrera GT2 RS (2010) has a 92.5" Wheelbase.

I think it has more to do with design than wheelbase, as noone will argue that a GT2 is bad at anything other than slaughtering a bank account.

/\ good point, but that porsche was also designed from the ground up for those power levels, and it's also rear engined. And it will put a hurting on your bank account for sure.

I'm not saying the Z will be unmanagable at 4xxwhp, but I doubt any nissan engineers were figuring that level of power into their designing the 370z.

Hmm, I just reread what you wrote and I think we're sort of saying the same thing...

Short wheelbases can be a concern with a lot of power output, but having owned a 700whp car with a 94.5" wheelbase, I can comfortably say anyone that is a reasonably competent driver should be able to handle FI power levels in the Z. It's not nearly as big of an issue as it is often made out to be.

I am considering 440whp or so. It's not like we are talking about something rediculous.

Cool, man! I hope that whatever car you end up in, you're happy with it. And I agree that buying a cheaper car allows for more financial flex.

I feel you on wanting a sports car after driving a sedan for several years. That's where I was last year.

I don't have the numbers you requested, but I had an '06 Z06 and have a 370. The 370 feels significantly more rigid. Actually, my pop's '10 Camaro felt more rigid to me than my Z06. The Z06 isn't a wet noodle by any stretch, but it doesn't have that billet-solid feel.

The Z06's aluminum chassis seems to have a tiny bit of initial flex, then tightens up. For example, when going up a driveway incline on an angle, you feel a small degree of torsional flex, but then it stops. It's tiny, but noticeable. Regardless, the car is certainly capable of handling its power (and more). Mine was fairly rattle-free, too.

Do you ever miss the Z06?

That was my impression of the C6 'vert I rode in, obviously floppier than a Z06, but it was pretty bad. The "initial flex" included 2 points that creaked every time we went over an expansion joint. One near the cowl, and one near the back of the roofline.
