Duratec (standard) has +45 HP and about +30T. Given the same tranny you could not help but notice a big difference. At least 1.0 sec in the 1/4th.. Zetec a bit better on gas but not much with both giving 30+ MPG highway.
More parts for zetec but even with big bux a N/A zetec will be hard pressed to outperform a Duratec with bolt ons.. One guy spent $5000 IIRC to get a British Zetec to 165 FWHP N/A...same as a stock SVT Duratec. And 3L Duratecs are another cheap option for 200+ FWHP.
Main zetec advantage...turbo. The kit is cheaper, the forged internals are cheaper, and its a simpler overall deal. If you are planning N/A..Duratec. But get a zetec for FI..
