I truly am gonna miss NA motors, they're so much more fun to drive. I love the high revving our motors like to do. If the motor in mine drops in the distant future, the only other motor I'd consider swapping in is a s52 to make it an even better NA. Torquey motors are fast but just not fun to drive. Half the 135i's on this forum can't even hook up tires since they make 400 ft/lbs at 2k rpms.
