We have frame 5 GE gas turbine of model MS5001K partially uprated to LA. Turbine is being used to drive a compressor at 4860 rpm. We want to replace existing tie wire second stage buckets with long shank shrouded second stage buckets along with large area second stage nozzle.

What adverse affect of this modification can occur.
