more psi for least amount of money possible

i recently subscribed to diesel power magazine and have greatly enjoyed the few i have gotten so far. the latest issue has something im wanting to try due to the fact that I have the main parts needed for it already. http://www.dieselpowermag.com/featur..._turbo_system/ I have a good operating WH1c on my Cummins right now. I have one i am rebuilding...jus need to get rotating assembly balanced before i put it the rest of the way together. and i have a good HE351VE. the guy in this article is using 3 H1c's all 50mm IIRC. all of them however have different exhaust housings. how crucial is the placement of each these... he has a 16 and an 18cm for the atmospheric turbos and a 14 for the manifold. what wud it do if he had one of the bigger ones on the manifold...(im sry my question mark key doesnt work on this particular computer im typing on at the moment) next Q where are they taking the 14 16 &18 measurement on these turbos... is it the inlet on the exhaust side... by compounding turbos if i used 2 WH1c's to feed a HE351VE that obviously is going to move a larger volume of air it gives you a greater boost pressure of say 60 to 75 psi based on what the article said. but im curious to know now how do you know when you overspool any 1 of the 3...
