    Urgent. RS2 Turbo to MAF hose

    Hi guys
    Am trying to fit all my new parts at the moment and I can't get the stock ABY turbo to MAF hose to fit
    I believe the ABY is 60mm and the RS2 is 70mm. Am I missing something or do I need an RS2 hose to make it fit
    Cheers

      Hmmm, would that be more or less work and time than getting hold of a new hose Who on here has done that move to the pressure side. Does it require a remap?

        Should be a straight swap from s2 to rs2.

        It does require a remap after moving the maf.

          Thanks Doug. I guess I won't do that just yet then!
          The MD147 is a stage 3 RS2 Turbo. It appears to have a 70mm outlet as opposed to the 60mm of the S2 / RS2 turbo.
          Does that make sense?
          Does that require a custom hose? If so, does anyone know where to get one from? It's the same stup as ApNess

            ah - ok - if you want to keep the maf hose - then you need a 60 - 70 adapter hose and a short section of 60mm metal tube - and you can make a short adapter for it - 60-70mm is the same size as the IC mod hose as well - HTH

                Greg has that turbo too i think, so he may be able to help before you start buying other bits to fit

                      Sorted as recommended. Fitted a 70mm - 60mm reducer and a silcone straight.
