Hi, I need help or advice with my RS 250 CUP. I change turbo from original to original hibryd and inyectors to 630 but only make 270hp to the wheels. Wich forge spring I have to put in the diverter and wastgate? I want only 310 or 320hp Thanks!
ha ha, you have right! but I banked my stock internal stage 2 RS to 385HP and later the new config, hibryd turbo with 630cc and water cooling intercooler, with the stock intercooler from 23 to 36 degres and only the torque goes up, to 45, but the HP only goes quickly to 370 and thats all. I notice they didn't change the turbo exhaust wheel
