R32/R33 front end on s13??

[Wake]

i read on some forum somewhere that the R32 or R33 front end can be directly bolted onto the s13 (89-94 240sx) chassis with minimal modifications I would really like to to know whether or not its true and if not exactly how hard it would be to do, i know the tex kit http://www.shibayama-tire.co.jp/tex/home.html
and the chargespeed kit http://www.chargespeed.com/photo/ext-force/s13/f.jpg are similar but i want info on the oem bumpers, out
