But FastCougar, On the SVT, you would not need aftermarket head, valve, cam mods - factory is fine for turbo at least up to 450 HP levels (probably want to do some heat resistant coatings in chambers & valves though). True, you need a few more pistons, rods, bearings (all more expensive for the Duratec because they would be custom), but the stock forged crank may be OK. In contrast, the nodular iron Zetec crank would be suspect in my book if going for big power. So, I do think the build up cost would be more for the Duratec but not that much more. I think on a HP/Dollar basis, if you are starting with a Duratec you will be better to stay. Staring with a Zetec, better to stay Zetec, cost wise.
