Why the alarm? A 4-cyl turbo Z = 240SX, Silvia, browntop SR20DET
It would be "cheapy-Z." When the Z32 debuted in N America, it was Nissan's halo car. All the JDM fanboys clamored for the Skyline GT-R because it was only available in Japan, Australia, England, and some other countries...They got their wish via the R35. R35 blows away prior gen "Skylines" in performance.
I expect the next Z to be 'watered down.' Nissan is gunning for sales i.e. numbers, not exclusivity. They already stated that they're not that happy with Z34 sales numbers overall. They want to whore out cars, not make them "low production, high priced" ones.
