All 92-03 standup stators/cdi and all 92-95 sitdown stators/cdi are compatible. The only box that you want to throw away are the 92s. Do not use the cdi if it has 3728 or 3729 on it. These have no high rpm retard and no rev limit. The 3733 box is good and will rev into the mid 7000 rpm range. The 3738 box was used on all big pin sxi and sxr thru 2003 and have a higher rev limit. This is the best box for high performance.
