You could build 100 500hp FI civics and still blow this motor on 12 psi with your bolt ons. (dunno) What is your point?
But your answer is yes, people have run 12psi on the stock botttom end, and for most of them it did not end well, and most knowledgeable people wouldn't dare run 12psi on your set-up, unless they didn't care about blowing a motor, or are just ignorant.
You ever hear the saying "ask a stupid question, get a stupid answer"? If you have all this experience with FI motors, and know enough to not need our help, you wouldn't be asking this stupid question.
