    How about taking Volvo K24-7400 to billet style?

    Cheers,
    P.

      Hank also builds k24-7400s with billet wheels and also had a new turbo based on the k24 7000 with a billet wheel and is making very impressive numbers with them

        that is the k24, what they said about the turbo:

        "Some billet k24 development taking place fresh off the dyno. This plug and play revision shows almost 70whp gains to the stock 7000 k24 despite spooling nearly identical. We have another revision in the works that should trade 100-200rpm worth of spool in the name of an additional 40whp and make this a contender with the billet rs2 we offer. "

              Second post from bottom of page:

              Turbo Swap weekend update:

              Drove to Vegas

              Swapped in one of the Iroz K24 Billet turbos

              Put down 265whp/285wtq on 91 and 310whp/355wtq on E85

              Full Setup:
              - Stock 3b Long Block
              - VEMS
              - 630cc Injectors
              - 4bar fuel pressure regulator
              - stock exhaust manifold
              - stock 90 fuel pump
              - 2.0 coils

              Overall I'm really impressed with how quickly this turbo spools and how well it puts down the power...

                  Google 'iroz 7200' or 'iroz rs2 billet', that info has been on their website for a while.
                  But there's not much info around yet on the 'k24 billet under development' (k24-7000?), especially figures or a like for like comparison with rs2 or billet rs2, and costs..

                      If you'e talking about the stock RS2 turbo:

                      Compresor wheel: 66mm
                      Inducer: 47,5mm

                      Turbine wheel: 59mm (K24!)
                      Exducer: 52,8mm (bigger than S2 K24, the RS2 turbo ist a very special K24 with another turbine wheel conture that is only used in this turbo )

                      Shaft: 10mm, which ist K26 Standard; the RS2 turbo ist made from a K26 billet, S2 turbo (and other K24) have 8mm shaft.

                      Peak Power ist around 350hp.
