It'll handle 300 all day. It's the extra torque of the turbo that slowly kills it.

Clutch type (my personal preference) or Torsen will go in there.

As far as handling, there are things that can be done to help the rear, like softening the upper bushes, and using loads of grease and locknuts to allow the inner race of the bushing to rotate. The roll centre has to be corrected by fabricating a new watts link or panhard rod.

There are some drawbacks to the FC subframe. the FC has very different chassis rails so putting an FC subframe in an FB adds a huge increase in ride height, or if lowered awful bump steer.

I think I'd probably avoid an FC swap, so would be looking at what was available for the FB's

In terms of roll centre adjusters, would something like this be the ticket:

Also, there is a panhard conversion kit:

Sorry to keep bringing up Techno Toy, but its just as they seems to have all the products in one place... They have a lot of products, but I'm not too sure what they all do!

Those RCAs are for the front suspension. The rear roll centre is a bigger issue and much harder to correct. Most T3 stuff is very good, but I would avoid those panhard bars, It's not particularly well designed, and I've seen shock brackets snapped because they aren't designed for lateral load and are already under engineered.
