Thanks for the help guys. Intercooler is infact a 700x300x70 and turbo is a t3/t4 to4e. The RB25s have side feed injectors correct me if im wrong? so 550 cc injectors would be big enough to see me into the 400hp range? i was thinking 650cc just to be sure fuel supply would be excellent and not lean out on me in the top end but if 550cc is enough i wouldnt want to go overboard with 650cc when i dont intend on replacing internals with forged anytime soon. Anyone roughly know how many PSI of boost to make 400-450 hp??

Hi guys, What do you think is the maximum horsepower which is safe to run at without disaster on my daily used Nissan Skyline 1997 GTS25T. looking at upgrading to reach max potential through upgrading fuel pump, injectors, regulator and a Link g4 storm computer. What size pump and injectors would you recommend? i was thinkin 500hp pump with 650cc injectors. Currently has a T3/to4e turbo with 40mm external and a intercooler around 700x300x70 (not too sure about the size will have to check). Was aiming for about 400hp realistic? Anyways apprieciate any help! Cheers Lionel
