I have Zetec turbo manifold as used by Power Engineering for their turbo conversion if you're interested?

You do need to ditch the standard manifold, but can easily link to another one as the standard item is in two parts with hoses linking the bit attached to the head and the runners/plenum part.

Other options are an FRS manifold, Adrenaline's item, the Fiesta Frenzy/Area 6 one......etc
