Differential /axle upgrade for 1200 whp S50B32 Twin Turbo Swap

[twinturbom3]

Planning on swapping S50B32 twin turbo engine, ECU, transmission from E36M3 coupe into an E30 Compact for the purpose of weight reduction.

Engine puts down 1200 whp. Works flawless on E36 M3 Euro Coupe, but need to go down to 1150 kg (2500 lbs)

What are the solutions to strengthen rear subframe?
I saw supra diff adapted by Dave Kern.

What other differential/axle solutions do we have for Compact?

There is a turbo build over on www.e30tech that utilizes a Corvette rear subframe.
