318ic diff behind M20/260?

[Lair]

I bought a '91 318ic with a dead engine and installed an M20b25 with a getrag 260. It runs like a champ, but I'm worried about the diff.

How long will it last?

Should I take it easy with it?

-I say change the fluid w some redline, take it easy, and don't be too suprised when it goes. But it may last a while!

i had a small case 4.10 in my M50 cabrio. It lasted for a long while. Ive since sold it. So i dont know if its still working.

I loaded up on Redline at the last NASA event. I'll change the fluid this week and hope for the best.

I swapped an m20 into my 318, and left the small case open 4.10. I have plans for an obx, but it's worked fine so far. Clutch dumps, burnouts, and chirping tires I would advise against.
