I've heard that the rods in the sr20 red top are weaker than those in the black top. Is this true?cause I thought they were basically the same motor w/ different valve covers. If they are the same, i've also heard that you shouldn't boost it on stock internals,but I thought that stock internals can take 400-500hp. Who is right!!??? If the rods aren't very strong then what about the pistons

 

U kan boost it on stock internals, i know of a shop that has one that is takin 25psi on stock internals!! thats right...25. And got about 450 HP(not to sure on that).
