ok, clear some things up for me, please!
why would it be a waste to sell your 200SX SE or what not to get an SE-R? the SE-R carries the SR20DE. so it's WAY better than any other of the trim models of the 200SX that carrie the pitiful GA16DEs.
next, i find it EXTREMELY hard to believe that you searched for anything related to the 240SX AT ALL. if you can't find at least ONE site pertaining to the 240SX, you didn't do a search AT ALL. there's a MILLION of those sites.
www.240SX.org
www.nissansilvia.com
www.zilvia.net
to name just a minute few of the millions of sites that are available.
