prelude

My car is a uk 97 turbo so i have the smaller turbo right?, i am collect parts at the mo to make the car rd 300 bhp at the moment it made 230 on surrey rr with just back box and decat centre .It now has aps inner wing induction kit different dump valve ( fancied a change) tsl back box a one off one ( again couldnt say no) and dawes( not maxed ) .
I was trying to track down a td05 turbo but is this the best one ?, im not sure i read alot of posts on here and i have read a post about moddin the uk turbo but i have forgot where?.
Also can i add a fmic before the turbo plus decat down pipe and remap?and do i need bigger injectors walbo fuel pump ?.
Basicly i need help with my list off things to collect im not in a hurry as i want to do it right and if i dont rush i can mod at a sensable pace still hav ea morgage to pay lol.
Any advice would be great and ill keep reading in the mean time .
