Ones Single pison and the other is Twin Piston I think the MFI is Twin not 100% sure tho A efi will run both without a problem but not the other way around 
and wen u remove the dump valve off a escort turbo mfi and leave the hose end open dose the engine go off ?

Yes m8 if you remove the Dump Valve you need to plug it with some thing i've a Alloy dump valve plug or abit of broom handle on any car tbh the cossie will run with a boost hose off but you dont get any boost ect im not sore if the FRST is the same 
BUT the MFI engine set up will Stop running
