What do i need to fit a turbo? to a 1.4 petrol engine? i have a turbo and intercooler?

hi ive got a car im using for a bit of a project for my missus im a painter so i bought a pair of peugeot 205 convertibles with the intention of making 1 good 1 out of the 2,it turns out ive managed to get the 2 running and she has 1 on the road so im going to keep 1 for a weekend mess around,i dont want to go down the gti route just yet but i probably will in the end,i have a garret t15 turbo and intercooler allready i know ill need a new manifold although have no idea where to get 1 from,i do have a knowledge of engines just not a vast 1,i dont know if it makes a difference but the car is running on the single point injection system not carbs,if anyone can help id be eternally gratefull,even if you know any sites with diagrams walk throughs ets that would be great
