Admin Paul Posted April 6, 2008 Admin Share Posted April 6, 2008 Just in the process of doing mine. If you need help just ask. The first hurdle is finding a Escort EFI wiring loom, the fuel pump will need to be upgraded but this is a easy job. Paul Link to comment Share on other sites More sharing options...

You will need to upgrade your fuel pump. Everything else will drop straight in. But you will need a OFAB or OFAC ECU and map sensor. Paul Link to comment Share on other sites More sharing options...
Admin Paul Posted April 6, 2008 Admin Share Posted April 6, 2008 You will also need the Air Charge Sensor from the Fiesta Turbo if you are using your standad EFI inlet. There are some pin changes on the ECU but sepends if you run OFAB or OFAC. I have pin outs if needed. Paul Link to comment Share on other sites More sharing options...

Paul im gonna try and get a battered/rotten fiesta so i should get these bits on it,apart from that sounds straight forward enough thanks 4 ur help Link to comment Share on other sites More sharing options...
Guest smoothy582 Posted April 8, 2008 Share Posted April 8, 2008 mfi fuel pump will be fine for efi, most things are a strate swap, you will need to swap some pins on the ecu multi plug. all info can be found on www.rsbible.co.uk Link to comment Share on other sites More sharing options...
Guest turbosy Posted April 10, 2008 Share Posted April 10, 2008 MFi fuel pump is actually better than the EFi pump.......more fuel pressure! Looms right, fezzy turbo engine, ECU (you need a few wires moving), air temp is different as is the map sensor Link to comment Share on other sites More sharing options...
