Inlet modifications, for intercoolers... help, i'm a fish!

[boymostfoul]

Am working towards fitting an S13 intercooler onto ol' Sil (bless her...) and was wondering if there were any quick fix or step by step, to working the piping out and fitting the boost controller and boost gauge on my CA18ET... i've caught up with a few Sil owners and it seems everyone does it different. Am I being stupid or is it a headache?
Cos' surely you have to mod it at both the turbo end and the inlet manfold end too, right?
I am a fish... but with help at least my Sil will be a lil' sweeter...
HELP!
Most Fizzle...
