I'm building a 96 ex trans and need a little bit of help from you guys. I'm ordering a full rebuild kit with carbon synchros, and a LSD. I need help with a few options I have to accomplish getting the best built transmission for what I'm doing. The car will be street driven but a weekend warrior as well. I will be using it at the drag strip and also autocross. I have 2 extra transmissions laying around 1 is a 97dx and the other is a 96cx. I want to know if I should use any gears out of those and which LSD diff would be best. I would really like a close ratio on 1-4 but a really low 5th.
