which block is better... i was talking to a guy that works at horsepowerfreaks.com and he told me that the s13 motors are stronger (better pistons and rods) than the s14 motors under boost. He also said that the s14 motors have a tendancy to blow at any boost level... some at 8 some a 15?

From my knowledge of KA's, ive always heard that a KA was a KA... but this guy says that approx after the 94 year, Nissan ditched the stronger S13 bottom end for a "cheaper" & weaker bottom end which they put in the s14's.

Can anyone give me more insite to what this guy is saying. I plan on boosting my engine to about 8lbs but i don't have the extra ~1k to build my bottom end. Im afraid that if i boost my engine it will blow and that will suk *** b/c im on my third motor and im tired of swapping them in and out!

It's total BS....I have at least 3 early de's and 3 E's and 5 late de's casting numbers on rods are different but quality and strength are the same in all parts. 7300 rpm and the rods break like twigs. the cranks are all plenty strong.

i thought s14 ka's have forged rods? while the s13 DE and Es had casted?

forged handles stresses better, and casted objects are general more brittle
