If you want to learn about the 240sx,the best thing to do is join a forum(already done) STFU and read,READ alot,just cruise all the threads ,read and learn its not that hard. Any specific questions(e.g. How much horsepower does the S13 KA24DE have? Wait,...you don't know what that is yet!

back on topic..) try to search for them,if you don't get a real answer then ask the question.
