    Intake, what do you guys make of this?

    If i understand correctly hes saying its got an increase in volume over the stock ABY unit. Can that really make much difference

    I noticed that on ebay earlier too, just looks like a cheap copy of an ABY manifold to me

      You can see the difference in this pic, cant help but thinking what a waste of time but isn’t an ABY intake larger than the 3B one?

      And is the RS2 manifold the same volume inside as an ABY?

        the upper looks like an ABY manifold, the lower a 3B manifold which has a lower volume

          Hi!
          Interesting...!
          Looks as though there are no ugly access holes. Also the injector bosses aren't drilled.
          So is it a new casting without any of the access bolt pillars inside the manifold (guess that would give you more volume) or a modified standard ABY one.

            Is there any point in changing an ABY / RS2 inlet unless you go the MTM style reverse inlet.

              Yeah it looks like a rough casting, i.e. you need to mill the mounting face's so there flat and true and drill/tap the bolt holes and injector mounts.

              Thats what i want to know Jamo, can it make any difference?

                Mmmm..
                Thats a lot of work. You would be better off either milling the access tubes out and welding the holes shut or sectioning the manifold and scooping them out. If thats the only difference between that manifold and a normal one. Unless you are a competent machinist with some nice bits of kit in your shed.
                Others have performed similiar surgery. Not sure what the result were though.
