Hi, new to this site and rotary in general. got an 85 rx7 a couple months ago and managed to overheat and warp the original 12a. got lucky and found a 13b (or is it 13a? not really sure) and now im trying to figure out what to do, use fuel injection or try to make the 13b a carbed engine (has fuel injection system on the motor but no wiring or pcm ecu or whatever mazda calls it

and thats what has brought me here to your site

I will be posting tech for help shortly.
