Depends on spec, you could have had 3.91 4.10 4.27 or 4.45

You would be much better off changing the engine rather than the diff

I am changing the engine for an m20b25 soon

Why do you want to run that ratio diff? Are you allergic to first gear?

I'm running a medium case 4.45 LSD built by Gareth on the forum details below.

The gearing is stupidly short but the M42 likes to rev. A roads are good fun using 3rd & 4th. responsibly of course.....

"Built using a E30 LSD with a E34 4.45:1 CW&P. The original two clutch plates have been replaced and all necessary parts modified to take 4 new clutch plates, ramp angles remachined from 45° to 30° giving a total lock upgrade from 25% to 75%"
