Have a Nice Day? ring and pinion swap for 92' legacy Turbo


I have a 3.90 LSD from a 92' Leg turbo and wish to swap the ring and pinion for something smaller like a 3.70, or preferrably a 3.545. NOTE: This is for a locost bike-engine project, not an actual Legacy vehicle (no front nor center differential issue). I need smaller ratio to get better top-end speed and spare the Hayabusa's tranny from destruction.

1) Can the early 90's SVXs ring and pinion mate on into my Leg diff.
2) If so, where can I find a ring and pinion? junkyard? or Subaru parts store?

The svx runs an r 180 doesnt it?
And isn't your diff from the turbo legacy is an r 160?
Are those internals compatible?
