I am finishing up with a rebuild of a 2.0 Duratec motor. It's going into a new Birkin. I understand that I need to purchase some intake pieces and a shorten oil sump from England. I have contacted to English companies that offer these parts but haven't receive responses in a timely manor or no response at all. I still don't know exactly what I must buy in reference to the new throttle body, ECU etc. I would appreciate if someone has a comprehensive lists of parts that are needed to convert the Duratec to fit into a Birkin and which parts are only available from England and which can be sourced in the US. Thanks
