Sorry, let me rephrase this question. What is the max safe boost pressure you can run on a 7.3 with blowing out the head gasket ect...
This is a completely different question having nothing to do with any turbo.
I personally would not try to surpass 40 PSI without springs, valves and probably studs too. Honestly if i was pushing 35 PSI consistently i would do springs and valves but i like my stuff to last and i like the piece of mind. Some will say you are fine especially at 35 but going past 40 and you will want do springs, valves, and studs. Its not a must do but its a good idea.
If your only running a 38R i would not upgrade these items unless you plan on going bigger in the future.
I do not have personal experience with this but i do a lot of reading.
