ej and transfer case?

[Uberoo]

I just bought a 91 AWD legomatic with 234K and a overheating issue for $120.It overheats after about a mile or so is what the guy I bought it from said,even though it didn't even warm up when I drove it on the trailer.So I will look at it after this rain stops and see what the problem is.anyway I bought it because my EA81 in my wheeler toy ingested some mud destroying the rings or the piston walls...Anyway at some point in the future I plan to T case my subaru and run 31-10.50-15's on it.I was wondering if anyone has ever ran an EJ in a transfer case subi,And what the results were?Im thinking the torque of the ej could help abit when in high range,but then as soon as you put it in low range does it destroy axles?
