Wow Winnie I would not be thinking of dumping that turbo mate! And before you go planning a heap of cash outlay on stuff to cool the sweat girl is be booking it in for a decent tune mate! There is likely Nothing wrong with it other than a really junky tune mate!!!
Seriously mate! You probably won't need the radiator and could get away with tuning it without an intercooler at about 14psi and get a power gain and great temps. This should be your priority 1 before any other plans for your car take hold mate. Truly.
