NEED HELP with DRIVE TRAIN

Guys,

I am about to get into a situation where I can get free garage time, and free help from a class one grease monkey. SO


What do I need to install Clutch, etc, so that when I get my car up to the goal of 425hp (with NOS) that I can feel safe about punching it?

Due to budget I am looking for best bang for the buck. This is an area that I am lacking in

Jason
