the larger radiator would probably be the reason, the more cooling capacity the better the cooling, engine heat it derived from combustion heat, intake heat, egts, its a vicious cycle, the hotter the engine gets, the higher underhood temps get, the higher underhood temps get the hotter intake temps get, the hotter intake temps get the hotter the air entering the turbo gets, and hot air being compressed into the engine only gets hotter with combustion, which exhausts into the turbo creating high turbo and EGT's which also feed higher underhood temps.... it spirals out of control, the best thing to do is open the exhaust, open the intake, and make sure your coolant system is in good working order, engine fan clutch, water pump, thermostats, even your radiator, make sure that its not full of gunk, i would even flush the cooling system, and start with fresh coolant, because coolant does break down over time
