Stock internals

Hi all, can the stock engine handle GTM 600 supercharger kit which if I'm not mistaken running 11 psi boost? On top of that the 7 AT gearbox, can it take such HP?

Actually there is some factual data on what the 7AT in the 370Z was designed for, which I found with some internet sleuthing in this thread over here: Nood questions needing your expertise (supercharger on a A/T)

The bottom line is our 7AT (Nissan model number RE7R01A) is actually a Jatco model number JR710E transmission and is officially rated to handle 295 ft-lbs (presumably that's measured at the engine output, before drivetrain losses for rwhp). There's another version of our 7AT transmission that's used in FX50/QX56, which is rated for 443 ft-lbs (Jatco model number JR711E). IMHO, it seems like it would be worth pursuing the idea of swapping in a JR711E from a wrecked FX50/QX56 as a cheaper alternative to doing massive internals upgrades on our weaker model. I'm not sure if they're 100% compatible in dimensions and ECU hookups, etc, though, and at higher levels of forced induction even that one would need more upgrades.

Anyway,once you modified your car,you expected the engine to have shorter lifespan,because of higher temperture it produced,esp we are in hot weather[Brunei & S'pore almost the same temperture].

Reliability of a car has much to do with how the car is driven and the aggression of a tune and supporting mods.
