Hi guys, I am following honda-tech forum for a long time and usually find my answers here but this time I am a bit confused, hope you will help me...
I have EE9 civic and at the moment it has H2b conversion with Y1(cable) tranny with OBX LSD... and it has usual issues ... I have decided to upgrade to hydro with shorter FD... so few questions here?

1. Will my OBX LSD fit in hydro boxes?
2. Drive shafts as I understand will fit to, yes?
3. Which one should I choose Y21/Y80/S80/S4C? 4.4 fd or 4.7 fd (car will be used for drag)?
4. Will Y21/Y80/S80/S4C mounts fit or I need some modifications?
5. What about cable to hydro conversion? is the innovative the way forward or there is better ways?


p.s. few pics of it:
