Miata gear swap

infernosg · 03-04-2013, 09:21 AM

I've read several threads on the evil forum and everything Mazdatrix has to say on the matter and I'm still a little confused how to proceed. I've gotten this far with both transmissions:

Everything I've read just says "swap the guts and modify the input shaft," which isn't overly helpful. Has anyone here done this swap/modification? What I'm trying to figure out:

1. Do I need to swap output shafts to keep the harmonic balancer?
2. Do I need to swap the 5th/reverse housing and/or bearing plate?
3. Is there an easier way to remove the input shaft than what's outlined in the FSM?
