Got the rear LSD from an RX, and a spare 3.9 diff to convert it. Problem is the RX diff is from a EA82, and the 3.9 is from my EA81. Will the 3.9 EA81 case bolt into the legacy? and will the EA82 diff hold up to the power of the EJ22T?

your car is a 91 it should already HAVE an LSD...
Also, unless you have the proper tools to set up the gears and bearing preload, it's not worth it.

Gee Hondasucks, look at his signature block, it will tell you it is a 92 Legacy Turbo. And the rear diff in the 91 was a VLSD, not a LSD.

Brian, yes it will work, all of the 3.90 LSD conversions that I have made were for EA81 cars and the 3.90 came from thoses cars. Yes, that rear diff will fit in your Legacy Turbo.

By WCSS I should have a 3.90 VLSD available, but it won't be cheap, next to the fabled 3.90 LSDs, these are rare, only available one year.

would it be wise to go with a VLSD? Or better to use the real LSD?

Either will work, VLSD really works better at higher rpms, the LSD works at any rpm. The difference is that the friction material in a VLSD is the viscous fluid, and in the LSD it is clutch discs.
