i have an 86 FC and im getting ready to buy a turbo. i was wondering if i could keep the NA engine ( yes i know the ports don't match up and that i would need a spacer for the turbo ) how hard and expensive would it be to have those parts made?

okay another question what are the bare minimum that i would have to swap for this conversion. I know i would have to get new ECU and wiring harness, what else do i need?
