12A to 13B?

I have an 82 RX-7 with a 12A and I just got a great deal on a weber carbed 13B out of a 1985 GSL-SE and I was wondering what all needs to be changed to be able to accomadate this new engine?
Thanks

You will need the front crossmember from the 13B.

It will bolt directly to the transmission. I'm fairly sure that the clutch stuff is the same. If not, swap the flywheel and clutch from the 12A onto it.

You'll need a new exhaust header.

I forgot to say that i got a new header with the deal so i should be good other than the crossmember.
Thanks
