TT 5.7 hemi in 75 duster

ok guys I am wanting your thoughts on this. The hemi swap is a sure thing, the TT is a want at this point. I debated going with a supercharger but I like the stelth look of everything being under the hood. I have access to just about any turbo off of a factory car, through a buddys junk yard. And seeing how I was planning on building headers for the hemi for the duster (im too cheep to buy them at $700 a set) so whey not just run them up front and mount the turbos instead of running headers. I have ported and polished heads on the motor as well as an aftermarket cam (getting changed out for a FI cam) I'm guessing the heads flow in the 325cfm range and plan on reving the motor out to 6500rpm so I need a good boost range that will come on hard about 3500 but be sustainable up to the redline. The motor currently has a stock bottom end and will only see 7psi. But once I build a stroker motor, I'm planning on upping the boost to 25-30psi. And I know the turbos will need to be swapped out at that time and that is really not an issue. What do you guys think about the cummins turbos? Any thoughts will be great thanks.
