well as far as engine internals go.....
1st the pistons...for the turbo you should be runnin a deeper dish..cr should be at 8.5:1...this is the best for the turbo,
2nd...rods...go to a better set like forged h-beams, i forget who all makes them, but i know scat does too
3rd....crank....even though this should be the weakest point because of the split throw journals, the powdered metal rods are goona give before the crank does, only thing id do for the crank is cryo treat it. it doesnt really pay to have the edges knifed, and filled with mallory metal..too expensive
4th...valvetrain...pushrods, rockers, valves, and screw in studs

granted all these things above are for going above 12psi constantly, i think out of all these i would most want new pistons to lower the cr, which keeps some stress off the rods
