I don't know anyone who has tried to fit a Duratec in a Fury but I do know that the Duratec can't be used with a Sierra/RS2000 bell housing as the bolt pattern on the engine is different to older Ford engines because it is a Mazda designed engine. Perhaps this is what Chris was refering to? As to who can supply bellhousings, I believe Caterham, Westfield, and Burton Power can supply bell housings to fit a Duratech onto a type 9. I believe these all use a hydraulic clutch. Burton also sell a number of dry sump systems, perhaps it might be worth giving them a call? Or take a trip to the Caterham showroom with a tape measure?

Editted to add that you could also try Raceline
http://www.raceline.co.uk/ as they seem to do a lot of stuff for the Duratec.
