Can an e30 rear diff be used on another rwd car?
I want to build a drift slag but don't fancy ruining an e30 to do it.

I heard once that the E30 casings are the same size as those from a Porsche 944 but I've never checked.

944 uses a gearbox on the back axle.

I believe people use the clutch plates in the diff to increase lock %.

As for being the same as an omega in fairly certain they're completely different.
