Putting the rotary back in
So I bought this 1982 Mazda RX7 gsl with a 5.0 5 speed out of a Fox body mustang but I’m looking to put the rotary back in but I want to put a 13b in it instead of a stock 12a but a lot of the stock stuff has either been cut out or Been taken out or not used so I’m wondering how much this would cost me and what I would need to put a 13b in

Personally I wouldn't do it, I would expect that in order to fit that engine and trans in there, they had to cut/remove/hammer sheet metal back. You'd probably find upon removing the engine that a lot of the mounting positions for various stock components no longer exist. Unless whoever swapped it provided you documentation of everything they did, you'd likely be cleaning up tons of little messes.
It doesn't look too bad, other than the shifter being way too big... I'd see if you can clean that up and just keep it as-is with the 5.0. Hold off until you can source a car with the stock motor if you want to keep it stock. ---- If you do keep the 5.0, look up the 2G to 3G alternator swap for Ford 5.0's. The 2G alternator (likely what that engine has) has the alternator charge wires (two thick black ones) routed to a plastic plug that plugs into the top of the alternator. This was a horrible design idea and is widely known to cause engine fires on 5.0 motors. The 3G alternator swap is basically bolt-on and allows use of a proper charge wire setup with a bolt and ring terminal which is much safer. Feel free to send me a PM if you'd like to know more details on the swap. |
