now this is what i meant,i have a fully rebuilt efi engine...block and head and was wondering if i could run the dizzy,im sure i could of but does not seem the case, the management comes with an mfi inlet and injectors which goes over the gearbox like the 3i style this should be ok to fit efi head,but its the dizzy part which i doubted would fit the efi headif i could run the coilpack it would be perfect,then i wouldnt need to refurb my other mfi head
