I can't find the spec for USDM S13 and JDM S13

[citanest]

i have been trying to find the spec difference between the USDM 240SX and the JDM S13.  I am looking for the detail differences like "master cylinder, caliper size, control arm, frame differences, sub-frame, etc...

I just couldn't find them anywhere.... &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=':('>
