So i traded my civic for a 94 civic hatch with a b20b4 tuned at 15 psi but set at 10 psi right now, I was wondering how do i know if i got a stock bottom end, all that i see on the out side is it looks like it has an aftermarket intake manifold and it has a moroso oil pan. Would it be safe to run it anywhere from 10 psi to 15 psi since it's tuned, and it's a daily driver.

the cloest you can come to telling is that you take out the spark plug and put a light threw it and see if it has a arrow ( ->) like that going to the timing belt side? if it does then you have stock piston. if not then the piston should be clean of any mark. but just to be safe as the owner and buy this one tool i forgot but its from the home deport that you can slide it in there and see it from the top camra.
