Heres a dumbass but legit question. Is it possible to swap a 13B Turbo Header and put it onto a 12A? I can't seem to find any headers that fit a 12A (For obvious reasons I guess). I was looking up parts and theres these headers that fit 79-91 13B RX-7's. Now if I remember correctly, they did introduce a 13B in the 84 FB's, but the true 13B's didnt come around until the FC's. Anyone tried to swap the headers before? Comon guys, I got an engine waiting to be turbo'ed!!!!! Im gettin ancy!!!!

 

the bolt holes are off by a slight margin, and should line up with the exhaust outlets holes fairly close, like within 1/4"... if it's the same as the 12A, 13B headers
