Question my 12a project

is it posible to use the fuel injection intake off of a 13b on a 12a. also will a transmission from a 13b bolt to a 12a. i just got into a a rx-7 i always liked them but never worked on them so if any one has any suggestions on performance and stuff because i dont know much i always work on small block chevys and stuff and i thought about putting the 350 in it but i said no because i want the rotory.

any suggestions?

you can buy an adapter plate from tweakit (IIRC) that will allow you to bolt up a FC/TII intake to a 12-A motor. At the same token, the LIM can be modded to fit all 4 injectors.

yes on the tranny except the TII's bellhousing must be changed to an old school so you can keep the stock 12-A clutch etc etc.
