Hi guys i am getting a mk5 escort cabrio, its already got RS2000 bonnet, bumpers but i am looking at doing a rear brake conversion to discs. Is this easy what do i need.

Also not sure what engine to change it to at the moment. Its a standard 1.8 efi but am in two minds to change to either an RS2000 or S2 Rs turbo lump any help would be really appreciated

Thanks Dave
