Fabricating Twins

I am thinking of fabricating a set of twins and was wondering how they are plumbed together. This there a special exhaust housing for the top turbo to connect to the bottom? Which turbo (big or little) is bolted to the exhaust manifold? If you use the stock turbo in a twin set-up are the exhaust pressures going be the same as when it is used by itself? Is it possible to install a larger exhaust housing on the stock turbo? How are twins wastegated? What is the best combo? I guess what I am asking is how twins are designed from beginning to end. Sorry for all the questions, but I'm just interested in doing it right the first time and the price of most kits seems high for the parts involved. If you use the B-1 ($1600.00) and B-2 ($800.00) turbos your only at $2400.00 in turbo cost, that's along way from $4500.00-5000.00 that the major guys charge.
