well you can make 170bhp by a simple chip upgrade and -31 actuator to hold the boost,then maybe either a kent or piper cam for longer duration( the time the inlet valves are open) and then a uprated intercooler like a pace 50% larger one or the new front mounted ones with one or two fans at this point you should see around 190ish,after this you will want to go for a hybrid turbo as the original t3 will stop at 16psi you will see just over 200bhp , i would then strongly advise you then start looking at low compression pistons arp con rod bolts etc........
