Is it possible to convert from auto trans to a manual trans in an 83 RX-7? I read somewhere the engines are different but I cant hardly believe that.

 

No, same engine. You need a new flywheel, counter weight, clutch, clutch pedal assembly, clutch hydraulics, tranny, driveshaft, and interior pieces (ie. shift **** surround, and if you really want, but not necessary instrument cluster). Plus, loose the tranny cooling system (which depending on your set up, might mean a radiator)... That sounds harder than it really is. The hardest part is getting the pieces and changing the pedal assembly.
