Uh. Try asking on a technical forum appropriate to the question.

Anything is possible, given deep enough pockets, creativity and desire.

Why bother? A correctly-built 3.3 turbo is a torque monster and doesn't need 6 speeds. Time spent shifting is time out of the throttle.

If you've built a un-streetable 930 with an insane amount of boost capability, little or no off-boost power and a very tight power band, it's likely in a lightweight tube framed car anyway (and should likely be making upwards of 800-900HP).

In a tube framed car there would be little difficulty in making any gearbox you want fit.

There are a number of examples of street-registered and driven 600, 700+ HP unibodied cars running a 5 speed.

If so what would all be involved.

All the boxes got longer (and heavier). The 4 speed and the short-bell housing G50s are the same length, or at least very close (enough to compensate by tweaking the mounts slightly).

The long bell housing G50 is longer by about 1.5-2" and requires moving the motor back, which increases the weight bias to the rear - not ideal. Most people shorten the bell housing and the shafts instead. Torsion bar tubes probably still need to be reinforced/modified to clear the longer end cap. This is expensive to have done by a shop.

The 6 speed is longer still - that extra gear lives in the end housing - and not by a small amount. I think it's even a long bell housing, just to make it more interesting.

That's a lot to move the motor back (there's not that sort of room before the rear cross member). The only other option is to recess the end cap into the body, and retain something resembling the stock mounts.
