  • EFI to Turbo Cylinder Head?

    I want to run a brand new efi head on my turbo engine - obviously with sodium exhaust valves and steel cam buckets. Is there anything I have missed to convert this efi head to turbo? Camshaft should be the same as turbo one - but I can't think of anything else that may be different?

    Any pointers would be gratefully received thank you.

    pretty sure there different.

    Although Im sure Dan or some one will correct me.

      Extra stud on the manifold I think.

      I think the valve guides are the same but as you have already mentioned the sodium filled exhaust valves will swap over hopefully.

        Thanks chaps - very interesting. I can't see the extra stud hole comparing the two cylinder heads I have - black one turbo/other thought to be efi? Or both could be efi? That would be disastrous if that were the case as the black head came of a gold-seal turbo engine and definitely shouldn't be efi?

            Are both these heads I have pictured efi or turbo then?

              surely the compression ratio on a turbo engine is lower, it would blow up otherwise.
              Non turbo head must presumably therefore have a higher compression ratio?

                Efi/turbo heads are flat to the block and don't dictate a higher compression ratio from the other. The lower cr in a forced induction set up in the O-series engine is achieved with pistons.
