Im pretty sure that factory turbo motors are built stronger with better internals and better cylinder walls but are they able to be at full throttle and full boost for long periods of time . I was doing some research about turboing hondas and I read in some threads it is not safe to boost in fifth gear for long periods of times . Is this only our motors since there not built for turbo or is it the same with all engines .

 

not really anything is gonna get super hot when you boost for a long time, some turbo cars didnt even come with forged internals.
