    318ic diff behind M20/260?

    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 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.
