Yeah I had a Tomioka lsd, With the old motor I was making about 320hp & 611nm which i thing is about 450ft lb at the wheels. Kennedy will make any any adaptor you want. My adapter is for a ls to gm set up. So im not making any kits. Personally I don't like any engine made by subaru. if you want a flat 6 just buy a 996 carrera engine. then the trans will also bolt up
