Ok my turbo went out so i order my 2871r with .86 ar and 54mm wheel trim. My current mods are tomei 550cc inectors , custom suction kit , z32 maff , hks air filter, apexi super afc , greddy 02 pipe , greddy down pipe , 3 " hks high power exhaust , and 3 " cat . Now i have heard ppl saying 550's are to small to reach 380-400 whp and that a enthalpy tune and 740 cc injectors are needed and my next mod is to be a aem wideband o2 . My question is whats the hp limit on the 550 cc and 740 cc .
