You don't need any more frame reinforcement than you normally would. People with SR and KA put out insane torque figures as well.

Definitely yes on the driveshaft, but the good thing is the Driveshaft Shop will make you one for around the same price as an SR/KA driveshaft, depending on how nice you are to them. Of course there is an markup for idiotic customers.

The etc. part will be hefty. It all depends on how good you are at fabrication. Everything will need to be fabricated or at least you have to mix and match stock parts.
