Another theorie 1993 Mazda RX-7 post...
Continuing with the fuel system upgrade, I decided to pick up some 1300cc injectors. With the stock twins, I wasn't ready to step up to 1600cc's yet, so for now 1300cc's should do the trick.
Stripping down the motor and the fuel rails:
Secondary rail on the left, 850cc vs 1300cc on the right:
1300cc injectors in the secondary rail on the left, engine bay reassembled right:
--- Update ---
Shortly after installing the 1300cc injectors, I decided to actually go with 1600cc injectors and a new secondary fuel rail. Install & write up coming soon...
