I'm gonna guess that lots of people are gonna tell you to ditch the SC for a turbo.

I dont think fs is the way to go at all , C-F-M , Mcnews can get you the same quality parts and in most cases for less money

Loose the cams may help some , FI and cams dont work well on the Zetec with FI and loose the SC for a turbo

Yeah I have to agree, Tom(1turbofocus) can get you to whatever power goal you want.

Not sure what type of SC you have but if you really wanted good power, i.e, more then mid 200's, you should have gone with a turbo!

Am I the only one to notice that the "head was bored out to 2.3L"??? Fairly sure this isnt possible... And if they lied to you about that, then I would start to question the internals too.

Actually if I remember right, Tom is the only one out there with a 2.3L setup for sale, but he does it by increasing teh stroke, not bore. I dont know if Eagle Rods does his stroker rods, so I would say that he is the first to ask. If he does use eagle rods, then maybe the previous owner did make your zetec a 2.3L but just didnt explain well enough.

Ya, its not possible to bore out the foci head to a 2.3 L . by stroking it, you use a different crank and different rods that are larger. say instead of pushing the pistons down 1.0 inches (numbers are ficticious for theory's sake) w/ the crank and rods, you push the piston down 1.3 inches. this creates more volume in the cylinders so you are creating more volume out of the stock bore.

www.focus-power.com its not the best website, your best bet would be to call or email him!
