twin turbo is a waste of time and money , properly sized single can spool sooner and make more power
how much work can you do yourself? (mechanical,fabrication,wiring +have all tools ect) does this include the car or need to buy that too?
as that will factor in whether it can be done for 10k ,it all adds up very quickly
with only 10k you will want an engine made for forced induction to begin with in my opinion be able to do all the work yourself
if its just an initial 10k to start with and don't mind spending more as you go its not so much of a problem
but if strict 10k knowing what parts you need/want before you start then add it all up for a proper budget and go from there
