im turboing my car during the winter while its stored, however iim stuck on 1 thing: twin turbo or single turbo??

i read that twins r more responsive (as in 1 per 3 cylinders) but then i also hear that a larger single turbo does wonders (duh!) but i plan to run more autocross than drag, so i figured i need it 2 spool lower, hence 2 smaller twins. can i get sum input from sum of u guys running boost?

 

how do the prices differ?

 

its all gonna a custom kit. mandrel bnt piping, t3/t4 hybrids turbo or a larger gt35r if i go singled, all lines, oil pan spacer, spearco intecooler, etc all the stuff i'd need, done my research, just need some imput on performance
