help needed for turbo info

hello all it is me again I have the other motor sorted out and again thanx to all for the help. now I have a new project on the board and once again I have come to all here for valued info and help.
I am currently in the midst of a twin turbo project idea and I have gotten a pair of fresh to4b18 turbos for little money so I am toying with the idea and need some info on these.
1. does anyone one know what kind of power level these can support?
2. what kind of boost numbers these are capable of I want to keep these around 15 to 18 to start.
I have been told these are capable of 30 to 35 but do not know for sure.
the part number on the 2 are 409570-5016 if this helps anyone I have not been able to find much on these.
3. recommends on cams I am planning to keep it conservative but want a solid roller?
4. also recommend a blow thru carb I know but this is a budget first to learn then maybe injected later on?
the bottom end is done 8.5 comp ratio balanced assembly scat crank scat h beam rods w/7/16 cap bolts and believe it or not with the dart 230 heads hopefully with a lot less issues this time.
so if anyone can help with advice and info on parts and power number and just informative views pleeeeeaaaa****se do so as I want to learn all I can.
I am not expecting monster numbers but it ought to run good and hopefully be fairly fast and a lot of fun. I would like to see a high ten or low eleven in the quarter. all thoughts on this please
thanx in advance once again
p.s. any helpful hints and tricks will be appreciated also advice on wastegates and blow off valves please THANX ROBB
