Hey, So putting final design down for my hybrids and have to decide whether to to use a billet K24 or 2283 compressor wheel? other modifications will be: - Upgrade compressor as above - Upgraded turbine 45.5x51 (OEM 45x50mm). - Clipped turbine - Competition 360 thrust bearings etc - Modified actuator 1.0bar. These turbos will be fitted and tested on my own RS6 hence the extra steps to reduce back pressure and if they perform and meet expectations (650+HP) I will consider making them as bolt ones for S4/RS4s etc. id appreciate your feedback on which to use, also please provide reasoning.
