Fellas, reread the title of the thread slowly "Stock motors(plural) that can handle alot of boost". There are so many motors that fall into this category beyond the jz motors and 4g63!, the sr20 definitely being one of them. There is no argument here. Now if the title of this thread was "Strongest Stock motor(singular) that can handle the most boost" then one can argue that the sr20 is not in this "league". As a matter of fact, the jz or 4g63 motors wouldn't be neither. I'm pretty sure in stock form the Bugatti veyron motor can make more power than "almost" any engine lol
