[QUOTE="yacob.naif, post: 1884752, member: 565696"] There's no replacement for displacement. It's the EXACT same argument as turbocharging a 4 vs. swapping in an 8..... with the ported single, or the turbocharged 4, you get: equivalent peak power, with less displacement, but with peakier and peakier response the more boost you try and gain (higher the tuning) and worse and worse SQ and transient response the bigger the box. (bigger the turbo, bigger the turbo lag, and worse and worse torque/hp ratio, throttle response) you have to decide on a desired peak output range in the frequency band, where you want to have equivalent power to the dual subs, tune it just right for the sound you want, SPL (drag racing) SQ (daily driver) street beats (lowend, auto-x) and tune it high (292 cams, big turbo, short intake runners) low in medium size box (260e/278i cams, big turbo, long intake runners) or low in a big box ( 260 cam, small turbo, long intake runners) And the benefits of the v8 swap/ dual ported is: twice the output through the full rpm/frequency range, at the expense of more weight, more money, and more fuel economy/wattage. It's plug and play, the oldest trick in the book. But you can have the smoothest response, and both quality and output. [/QUOTE]
