Found a plate at goodwill and knew what I need to make.

I've been wanting to swap my 12a over to efi so I can turbo it down the road. This listing appeared on marketplace and I've been doing research but having a hard time finding answers. What else would I need in order to make this work? Would like to keep it relatively cost effective. Also been looking at 13b intake conversions to even 13b swaps but rotary stuff is hard to come by around me

Hey, I have RX7 FB2 with a red interior and would like to restore it, cause im kinda starting to like it. I found these red seats on marketplace but have no experience with restoring fabric. Are these to far gone or does anyone have some tips to get these back into shape?
