ok yes you can use the fiesta efi inlet,also the rover one,the easiest inlet i would say to use would be the rs1800 efi jobbie as it can flow 300+you then could get away with using fiesta charge carrier and make your own hoses to suit, what are you doing for internals,if you are running reliable high power you would need a low comp pistons and steel rods,some people have just used a decomp plate,
