Hello, i have a k03 turbo upgraded to 43/56 11 blade compressor wheel. K04-064 Turbine wheel and K16 thrust bearing. With this combination i have achieve 330hp at the crank. Now its the time to upgraded one more time. and i want your opinion. im thinking to upgrade my compressor housing to K04-023 and adding a bigger compressor wheel 46.4/60 11 blade with k16 thrust bearing and again k04-064 turbine wheel and to reduce the backpressure i will add an external wastegate . with this i ll try to reach 350hp. Do you believe 11 blade is better option than classic 6+6? Do you believe that o will reach my goal of 350hp? Thanks in advance.
