I enquired about this last week and got this reply from Cosworth:
"Thank you for your enquiry regarding our Inlet Manifold. Cosworth is currently working towards releasing a second inlet manifold with longer trumpets, which will be better suited to the 2,0 Duratec. This will be available towards the end of the year and I can confirm that it has been packaged with the ST150 in-mind. It may be better to wait for this than try and package the manifold that is currently available for the 2,3 engine?"
Sounds like it is a little later than planned, but will hopefully be better suited to the electronic throttle body rather than the US Focus/Mondeo mechanical throttle body and air bypass valve.
I think that with the intake manifold, K&N cone filter, Milltek 4-2-1 exhaust manifold + de-cat, 2.3 ETB and a tweak to the ECU this should be putting out an easy 200HP.
