60 degree I <3 Bananas, I have a standard plenum, cold side intercooler piping is 2inch 3/4 Not even 3inch. and the intake temps are no over 40 deg.. all I have to say is go see MICK @ Pitlane. my forged motor is noisy too but bearable.. like other ppl have said, a forged motor is not going to sound quite like stock standard will. if u get a fg bottom end your going backwards.. best thing to do. for peace of mind pull the motor out and put new forgies? *get another opinion, go see Mick @ Pitlane *get a desent intercooler *get the car checked over. good luck with sorting it out
