Ive just put an r33 5 spd into my vl and i knows there already alot of threads about it but just wanted to make sure I put the speedo drive into the box that you buy from nissan after doing research and its 20kmh out or so did i do something wrong, the only thing is ive still got an auto computer could that effect it and im wating on a computer but i jsut wanted to check and make sure i didnt do anything wrong.
