I converted a 1.8 cvh to a pinto years and years ago, it was awkward as the fuel lines were on the wrong side. It would've been easier putting an EFI tank and lines in with a pinto EFI running a loom/ecu out of a granada mk3 (as these are separate to the main loom) I've not converted to a DOHC but you'll certainly need a EFI fuel tank and pump etc. Maybe a late mk3 grannie has a separate engine loom but I'm not sure, the pinto ones definitely did. Not mega helpful but a cool story none the less... Also my first post in 13 odd years, strange how my old posts are non existent?
