Gotta question!?
 

ok, im new to rx-7's and im trying to learn. i have a question about the engines. which engine is better the 12a or 13b?:confused: might be a stupid question but i know jack shit about 7's. if u have any other information that i should need to know about, please let me know. thanks:confused:

Well the 13B has more displacement than the 12A, so it has the capability to make more power. However you can get good power out of the 12A and its lighter and smaller than the 13B.

Go thru the FAQ posts at the top of this forum.. There is a ton of info on our engines and are cars in general. Also, do a search on google for info on wankel engines. Good luck and welcome to rotary life.

thanks, i've been hooked for a while so im glad yall could help
