I'm looking at doing a K24 turbo RWD swap and i'm considering using a RX7 FD box because they are easy to find over here and not too expensive. The Honda F20C boxes are hard to find and expensive and still not a bolt on option. I've considered the RB25 box also, but the RX7 boxes are cheaper and easier to find. So the question is, how much torque can these boxes handle? I'm planning for no more than 400bhp (350ft-lb?) from the K24 and it will be going in a retro car, obviously running an LSD the rear tyres will be no wider than 205. Any other suggestions appreciated.
