Combining Turbo parts?

[Tom Egbert]

  I have just completed this project with advice from an audifriend in Ohio. He has more experience with conversions and power adders than anyone in the states. 
     Start with a Porsche K-26 from a 944t. The part number must be 5326 970 67## The 67 digits is the compressor and turbine that will produce the most efficient boost and flow the most RPM.  Plain audi K-26 won't give as much benefit.
     Then take the compressor and turbine wheels and housings from the Porsche turbo and rebuild an audi K-26 center section and build it. Take the shaft and wheels to a reputable turbo shop to get the rotating components balanced. The shop must have a KKK approved machine and they will mark the new nut and position the wheel so you can put it back together oriented the way they balanced it. (Very Important)
     My turbo is ready to go but I don't have the guts to do it yet. The rebuild kit cost 94$ and took 3 weeks to come from Europe. The balance was 25 and the used turbos were cheap on ebay. The porsche was harder to bid and win on. 
     I have ridden in a 200t with a K-26 without the RS2 manifold and I wouldn't bother. Too much lag. 
      Best of luck, Tom
