hi, ive just had the idea spring into my head to convert ny s2 turbo to efi, ive just bought a rotten fiesta turbo which is standard and in good running order, i would like to use my mfi block but ive read some threads on here and it needs to be drilled and allsorts! would i be better off just swapping the whole engine and loom over? my mate is an auto sparky so the loom is no problem.
