ok, in the 1st bit when you say intake you mean from filter to turbo? so filter, MAF housing and intake pipe. well i was going to try and duplicate as much of the Kinetic st.3 kits as possible which afaik uses the 3" MAF housing and intake. with regards to your 2nd bit are you still refering to the intake or the inlet mani? so if i use the ATP turbo mani i have to go SRI? if i was to use a lhd mani from the US would it be just a case of getting a custom DP made up? really dont wanna go SRI if i can help it
