if i don't even need internals to get 600bhp what will the combo i posted in my first post make? Will it be unreliable? How much will the z drivetrain handle then? Ifi take good care of the car with all the aforementioned mods will i be able to get 100k out of hte engine like i would a stock Z motor. Thanks for all your help guys. I just gotta get over worrying about breaking stuff.
