    Injector advise please.

    I am currently collecting parts to convert my S2 aby coupe to RS2 spec.
    I have a brand new Borg and Warner K24 7200.
    New Wagner evo exhaust manifold.
    New Wagner intercooler.
    New HRC fuel pump.
    Is there anything else I need?

    I have been looking for a set of Bosch RS2 injectors new or second hand, but had no luck.
    My question is this, can I use a more modern easily available equivalent Bosch injector for this set up and use one of the generic chip sets available (TS, Homefries, are there more?)
    I don't want to go down the custom mapping route.
    I purely want plug and play.
    I have seen a set of new Bosch RS2 injectors (280 150 984) on eBay.de for €699. Which I'm not prepared to pay.
    Have been advised not to use 034 replicas.
    Could I for example use these

    and use a generic chip set?

    Advise please.

      The injectors in the ebay link would not be compatable with a generic chip as they flow more than RS2 injectors.

        So I also need a 3 bar map sensor. Thanks Rikki Kitto.

        I understand now that I can't use the injectors in the link. I see that RS2 injectors flow at 360cc/min.
        Can I just buy some modern Bosch injectors that flow at 360cc/min and use generic software? Or will this not work correctly?

            If you let me modify the ECU then all parts internal to the ECU are included (MAP sensor and other bits), so you don't need to buy them separately.

            As for injectors, get the 0 280 155 968 ones.
            They are a bit bigger, but plug and play fit and the map can be accommodated to suit. I have a generic map for these with RS2 setup.

            Also, what you need is an improved exhaust on the S2, the stock one is too restrictive.

              injectors

              Thanks for your post PRJ. I have sent you a pm about remapping.
              Where's the best place to buy the injectors you mentioned?
