2.9 V6 turbo capri differential

Just a quick question for the above car,

What was the choice for the rear diff on that and what did fitting involve, i think my stock diff will take take the output on the na engine, but when i go turbo i think it would die quick.

If you mean my Capri it has a Volvo Rear axel with a welded diff (temporary solotion). Not really hard to fit but neds modification on the driveshaft and a loot of grinding and welding on the rear axel.
