^sorry, I should have been a little bit more clear...i figure when I say names like Mitsubishi, Subaru, etc... you would only think of EVO's and STI's. Yeah the "other" mitsubishi's (the ones really made by Chrysler) are crap...but the EVO and the true JDM Mitsubishi's are exceptional cars!

Transmissions ARE based on "load tolerance", but more specifically, stress resistance. I never said that they weren't.
Also, strength is not (stress/pressure) as you stated. Strength is simply measured by a material's relationship between stress (load/area) and strain (deformation under load). So, to design a strong transmission, you want gear sets that can withstand lots of load over a given area, with minimal strain displacement (deformation). But this is getting off topic here....
I agree with you that the VQ35DE is not as strong as some of Nissans other motors in the past, such as the VG30DE and the RB26DETT. However, if you are not adding forced induction to the VQ, then whats the difference? The VQ is strong enough for its intended application. Just because the VQ cant handle 1000 hp on the stock block doesn't mean that the engine is somehow inferior. Nissan engineers decided to go for weight savings with the VQ in the Z, and this improved the handling and weight distribution. They *could* have gone with some cast iron block VQ thats super stong and can handle lots of boost, but then the car would likely have weighed 100 pounds more than what it allready is. And trust me, the last thing the Z needs to do is gain any more weight.
I understand that cars like the M3 may demonstrate higher levels of engineering prownes than the Z, but thats why those other cars cost so much more. The STI and Evo may have super duper motors, but the cars themselves leave a lot to be desired in the build quality department, esp in the interior and body panel gapping.
And finally, I dont know what your deal with the Lambo is, but making the argument that a 200,000 dollar Italian exotic uses all forged internals, and therefore the 30,000 dollar Z crap because it only uses a few forged internal parts is pointless.
Have you noticed that S2000 motors do not take to turboing very well either? Both the S2000 and Rev-Up 350Z make use of high compression lightweight motors that are designed to be NA. Bolting on a turbo kit and wondering why the engine is not reliable and calling the WHOLE car crap is nonsensical. The VQ35DE was never meant to be a turbo motor, and thats what Nissan intended. The reason the Evo and STI are so stout is becasue they were designed to be turbo motors from the start! Of course they are going to be stout.
If you think your Z was somehow "crap" just becasue the VQ cant handle some moster turbo kit you wanted to put on, then I rest my case. If the VQ was intended to be a turbo motor, then Im pretty sure you would have seen the stronger internals, and stronger block, most likely cast iron. Nobody's VQ35DE motors are blowing up in their Z's, so I dont really see why you think the motor is so unreliable, or so weak, or so inferior.
Likely the new VQ35HR is going to provide a stronger block (Its intended to be a turbo motor -> GT-R) and stronger internals to handle the extra power demands. And Im willing to bet we will see a new transmission design as well.
Nissan is capible of producing cars that rival or beat the best from Germany. Just look at the new M45. It beat out BMW and Mercedes and Lexus in the recent issue of Car and Driver.
