hey guys im looking into doing a swap inmy fb and im looking at all sorts of rotaries and the thought of a 3 rotor has come up. does any body know what would be involved in doing the swap? also could i just run a carb until i could afford a miroctech?im thinking like single turbo setup with that. i know it wouldnt be ultimate power potential but this is my daily driver and the power even wit a carb would be plenty for now any pics and info would be great.

 

The 3-rotor swap is incredibly expensive and difficult. Make sure you have a build list before starting the project, as you may want to consider a 13BT once you see what is involved. These sites are based more on a 2Gen RX-7, but the 1Gen RX-7 wouldn't be much different.

This 1Gen RX-7 has a custom-built 3-rotor, but a 20B swap would be similar. A 3-rotor engine custom built in the US would cost too much to be practical for most people.

The 20B-REW 3-rotor engine already comes with fuel injection and two turbochargers. If you used new components, it would actually cost you more money to convert it to a carb than it would to buy a Microtech LTX-12.
