2) you're rolling the dice with forced induction. yes, it's been installed on a stock motor before. none of them have blown up..yet. but forced induction means the motor is seeing more stresses, no matter how you drive it.
there, my opinions. please, PLEASE just use the search next time so we don't get a failtrain going...

Stillen is in the process of providing engine warranty for the supercharger. Your point on engine blowing up with forced induction is mainly a thing of the past. The engine in the 350Z and 370Z handles it greatly and unless used weekly on a track and provided that the normal maintenance is done correctly, the engine will last over 150,000 miles...
Of course you may have to change a few engine part but you may have to change them on a poorly maintained stock car also...
